Since the Patent Act was revised and the new Patent Rules were introduced in October 2019, Canada’s IP scene has been looking vibrant. Although the bulk of the instructions that cross the desks of practitioners concern the life sciences, technology briefs are also flying in – a trend which has much to do with the reshaping and fine-tuning of the IP regime. For instance, after the Federal Court rejected the Canadian Patent Office’s original ‘problem-solution approach’ in Yves Choueifaty v Attorney General of Canada, it issued new guidance, outlining a three-step method for determining patentable subject matter. The new method focuses on defining the claim’s true invention and determining whether that qualifies as patentable subject matter. As a result, Canadian applicants seeking patent protection for computer-implemented inventions should now emphasise how the invention enhances function or solves problems. On another note, the new trade agreement between Canada, the United States and Mexico, which took effect on 1 July 2020, will affect all IP rights in Canada, including patent rights. One significant modification will be patent term adjustment to compensate for unnecessary delays caused by the Canadian Intellectual Property Office (CIPO) during the review of an application. This is expected to be introduced within the next four years and will be of great interest to patent holders, especially in the pharmaceutical industry. Aside from legislative changes, the country has remained stable and has seen a steady rise in work, which has allowed new players to make their mark on the legal landscape and is evidenced by new entries to the firm and individual tables.

Firms: litigation

Firms: prosecution

Firms: transactions

Aird & Berlis LLP | Aird & McBurney LP

Dynamic outfit Aird & Berlis | Aird & McBurney has been going from strength to strength lately: its prosecution practice is widely respected and its contentious division has started turning heads too.

Aitken Klee LLP 

Elite litigation firm Aitken Klee is home to a crew of seasoned trial lawyers who are resolutely focused on securing the best results for their life sciences and high-tech following, whether at home or abroad. Lately, Marcus Klee and Jonathan Stainsby have been staunchly defending Pharmascience against Eli Lilly in an infringement claim. Managing partner Klee has several landmark judgments to his name; while Stainsby’s contentious prowess extends to employment and other commercial disagreements too. IAM Patent 1000 newcomer Scott Beeser has rare experience as the first biopharmaceutical patent attorney at an international generic drug manufacturer, which he has leveraged to chalk up an enviable track record in litigation under the Patented Medicines (Notice of Compliance) (PM(NOC)) Regulations. He recently teamed up with Stainsby to successfully defend Taro Pharmaceuticals against an infringement claim, the result of which allowed Taro to enter the market five years before the expiry of its patent. All-rounder Bill Mayo executes a variety of instructions with finesse, from validity opinions to strategic advice; his deep understanding of regulatory issues is a major plus for his life sciences patrons. Neuroscience and biomedical engineering maestro Bryan Norrie has “carved out a real presence at the Bar”. A “brilliant and persuasive litigator”, Michael D Crinson has been representing Maoz Betser-Zilevitch in a patent infringement case relating to oil and gas technology.

Baker McKenzie

International powerhouse Baker McKenzie is a household name when it comes to intellectual property and its Toronto arm makes astute use of the firm’s sweeping geographical coverage and treasure trove of resources to bring home the wins in commercially consequential cases. It has continued to represent Burlington Northern and Santa Fe Railway Company in an infringement suit of utmost significance, as the adverse party’s patents threaten to monopolise the use of web-based e-commerce tools for the pricing and ordering of goods by rail between Canada and the United States. Running point on this case are William Richardson and Kamleh Nicola. Highly regarded by peers, Richardson has a steady hand when battling it out in complex disputes, but his client-centricity means he also looks to settle out of court where possible. “A phenomenal mentor with a high profile in the IP community”, Nicola works diligently to reduce the risks that her patrons may face. One of her specialities is navigating the intricacies of the country’s dynamic health regulatory regime.

BCF Business Law 

BCF Business Law earns plaudits for its “exceptional client focus, responsiveness and personalised but cost-effective service – it really feels like an extension of an in-house team”. Its diversely talented attorneys cooperate in a collegiate style and “can handle a vast range of complex technologies with ease”; “extensive knowledge of Canadian, US and European patent law” is another draw. On the biotechnology side, Andréanne Auger works closely with developers and their early-stage inventions to provide cogent advice that adds value to their creations. Tuba Yamaç holds a PhD in biomedical materials and fluidly guides start-ups and multinationals throughout the patenting process. Software and telecommunications ace Julien Lachere thrives when tackling ground-breaking technologies and has been vital to the development of the BCF Imagine programme, which provides vital support to Quebec-based start-ups. Ilya Kalnish and Dominic Goudreault shine in the mechanical arena. Kalnish is “an outstanding patent attorney with strong business skills and a high level of professionalism. He has a remarkable capacity to comprehend complex inventions, draft excellent applications and help his clients in making strategic decisions. He is a total team player”. “Dominic is extremely well organised and structured when drafting applications. He gets straight to the point and omits verbiage; and you can count on him to deliver as promised.”

Belmore Neidrauer LLP

Belmore Neidrauer is an invaluable partner in complex litigation, thanks to its eloquent, strategic and technically savvy advocates. The side tackles disputes for some of the leading names in the pharmaceutical industry and recently prevailed for Janssen in a patent infringement action against Teva under the new PM(NOC) Regulations involving Janssen’s schizophrenia medication. Taking the lead on this matter were Peter Wilcox and Marian Wolanski. Litigator par excellence Wilcox heads up the group and is a repository of trust for the likes of Pfizer, Bayer and National Oilwell Varco. With a refined understanding of biotechnology, Wolanski adds great depth to the practice and is a compelling performer before the courts.

Bennett Jones LLP

Equally as impressive in prosecution, litigation and transactions, Bennett Jones’ patent agents and lawyers work in tandem to produce exemplary results. With offices in Canada, the United States and China, the side serves clients all over the world and has developed an extensive network to call on for back-up as needed. The prosecution unit can handle matters in a variety of fields, but flourishes in the life sciences, where Irene Bridger and Edward Yoo capitalise on their backgrounds in microbiology to advise major players. Adding to its dexterity is chemistry ace Roseann Caldwell, who brings a strategic eye to the management of large portfolios. Dominique Hussey is “a delightful and very well-known lawyer who is extremely active in the profession”; her mastery of regulatory issues also comes in handy when executing licensing agreements. At the heart of the transactional practice are Stephen Burns and Michael Whitt, who both bring longstanding experience to the table. Burns is at home leading large multi-vendor outsourcing transactions, and Whitt is always on hand to provide commercially on-point advice.

Bereskin & Parr LLP

“Bereskin & Parr is the type of firm you can entrust with absolutely anything – it will always deliver excellent quality and added value to its clients, while keeping costs reasonable. The team is extremely responsive to client needs and innovative in suggesting effective strategies. Unsurprisingly, it is at the top of any list for IP representation in Canada.” Leading the litigation group is Andrew McIntosh, whose chemistry background and smooth advocacy skills make him well suited to technically intricate disputes. Lately, he has been defending Nova Chemicals alongside Robert MacFarlane and Adam Bobker in a claim for the disgorgement of its profits relating to a patent infringement suit brought by Dow Chemical Corporation. Courtroom supremo MacFarlane has been stacking up the wins for more than 40 years; Bobker is “a bright lawyer who thinks on his feet and provides clear guidance in disputes and smart strategies in injunction proceedings”. The pair recently linked up with IAM Patent 1000 debutant Joshua Spicer to represent Packers Plus Energy Services in infringement actions for damages and accounting of profits. Spicer is acclaimed as “an excellent litigator who strikes a balance between what is required from a business standpoint and ensuring patent rights are identified and protected to the full extent of the law. His advocacy, work ethic and attention to detail are exceptional”. Coming through for GlaxoSmithKline are Donald Cameron, Scott MacKendrick and Melanie Szweras, who have been meticulously handling two proceedings against Sandoz and Gilead relating to its HIV medication. Cameron is a trusted ally of innovators in the courtroom, having served as senior trial counsel in Canada’s first-ever DNA patent trial; and the esteemed MacKendrick is likewise at home when acting in hefty disputes. Versatile multi-tasker Melanie Szweras combines litigation and prosecution capabilities to provide detailed guidance that considers the entire patent lifecycle. Also new to the guide this year and bolstering the firm’s prosecution offering are Carmela DeLuca and Jason Hynes. A co-founder of the Greater Montreal Chapter of Women in Bio, DeLuca advises start-ups and universities on biotechnology and pharmaceutical applications, as well as plant breeders’ rights. Those who have collaborated with Hynes have nothing but good things to say: “Jason’s technical knowledge and ability to quickly understand inventions are fantastic. From the beginning, he made it clear that he was there to do the heavy lifting and make the process as painless as possible.” Life sciences division spearhead and co-leader of the cannabis practice Micheline Gravelle is not afraid to stray off the beaten path in search of innovative solutions to protecting patents. She is key counsel to Autolus Therapeutics and has seen through many of its applications relating to the use of CAR-T cells in the treatment of cancer. Similarly, Patricia Folkins relishes working with emerging technologies and has recently been filing for OICIR in relation to its first-in-class pre-clinical therapeutic targeting the WDR5 protein for the treatment of blood cancers. She speaks the language of inventors thanks to time spent in-house at a leading biopharmaceutical company. On the mechanical side, Philip Mendes da Costa and Robert Storey are the names to note. When it comes to the strategic development of patent portfolios, Mendes da Costa is the go-to; while Storey has cultivated deep reserves of knowledge over his 40 years of practice and is a font of wisdom for a high-flying clientele. The firm’s patent offering is completed by a razor-sharp transactional practice, which is home to Bhupinder Randhawa, Victor Krichker and Noel Courage.

A tenacious advocate, Skodyn has a cracking pharmaceutical practice and commands the attention of the courtroom. The pair make a great team, having spent most of their careers working together, and have been busy representing Genentech, Biogen, F Hoffman-La Roche and Hoffman-La Roche Limited in an infringement and validity action concerning an innovative biologic treatment. Other highlights include acting for Facebook and Instagram. New recruit Christopher Hunter has settled into his role perfectly as captain of the commercial IP group. The mechanical engineer views intangible assets through a commercial lens and has been advising GlaxoSmithKline in connection with its collaboration with Medicago to develop, evaluate and manufacture an adjuvanted covid-19 vaccine candidate. Lululemon is another key client: Hunter shrewdly advised it on its acquisition of Mirror, a home fitness start-up.

Borden Ladner Gervais LLP 

A prolific patent filer, Borden Ladner Gervais (BLG) is a trusted adviser to industry leaders and innovators across a range of sectors. Its bench strength and technical prowess are simply undeniable, especially with 12 individuals recommended for prosecution this year. The life sciences are a forte here, especially with eminent experts Mark Vickers, David Nauman, Scott Pundsack, Jennifer Raoul, Kathleen Marsman and Graeme Boocock on deck. National life sciences group leader Vickers is a hands-on, big-picture thinker with a percipient approach to developing portfolios; while Nauman is a favourite among entrepreneurs, academic research institutions and government organisations for his astute strategic counselling. As a lawyer and a patent agent, senior counsel Pundsack is an excellent choice for litigation and opposition support.

Brion is closely involved in Canada’s start-up community; his friendly manner and strategic vision have helped a multitude of fledgling inventors to transform their ideas into thriving businesses. Raffoul carefully shepherds companies through the rocky terrain of software patenting, has a refined understanding of business methods, artificial intelligence (AI) and machine learning, and knows how to carve out a route to optimum protection.

CPST Intellectual Property

Since opening its doors in 2020, CPST Intellectual Property has been making waves on the legal landscape. While the outfit may be young, the collective experience of the team is nothing short of impressive and over half of its prosecution pros feature in the guide this year. Life sciences whizz Santosh Chari brings more than three decades of wisdom to the mix and is a great port of call for international applications. Having started out as a researcher at a major biotechnology company, IAM Patent 1000 newcomer Leah Begleiter Rodin understands the business value behind strong patent protection and develops portfolios efficiently. Novel technologies never faze Brett Slaney, who comfortably navigates tricky AI, quantum computing and blockchain matters. The dual-qualified Anthony Prenol solves complex problems from an inter-disciplinary perspective, given his comprehensive prosecution and litigation know-how.

Dickinson Wright

Headquartered in the United States, Dickinson Wright operates out of 19 bases in North America and has some 475-plus practitioners on hand to dispense pragmatic solutions and sound guidance. It recently drafted superstars Yuri Chumak and Matthew Powell into its ranks and as a result, the firm makes its debut in the Canada rankings this year. Chumak counsels diverse clients in the computer and software space as they make strategic moves both at home and further afield. He also showcases his versatility through his extensive experience in complex trial and appellate proceedings. “A great guy to work with”, Powell “is responsive, understands complex technologies and has a strategic mindset that helps shape a company’s entire patent strategy. He knows that inventions are pursued as a means to create revenue and goes out of his way to help his clients, even leveraging his own personal network in the technology space to make introductions and connections”.

DLA Piper

An integral part of one of the largest European and international patent groups, the Canadian contingent of DLA Piper works with its counterparts all over the world to provide joined-up support to a discerning client base. For example, Bruce Stratton and Alan Macek have been representing Videotron, one of the country’s largest telecommunications providers, in infringement proceedings brought by Rovi and Tivo; and enforcing patents for Canadian Energy Services to ensure that it retains its competitive market position. Stratton is hailed by peers as “an excellent and thoughtful litigator”; while Macek is always up to date on the latest developments in the field and receives praise for his “client-focused approach”. Joining them this year is Geoffrey Mowatt, a superb litigator with an intimate understanding of regulatory and compliance practices. He and Stratton have recently been acting for Pfizer in Canada’s first biosimilar patent infringement action, brought by Janssen.


Canadian titan Fasken has more than 750 lawyers and agents stationed across seven bases in the country and in Beijing, Johannesburg and London. Its prosecution, litigation and transactional experts work hand in glove to provide practical, business-driven solutions to clients of all shapes and sizes. Pharmaceutical and biotechnology companies embroiled in high-stakes disputes can sleep soundly with Julie Desrosiers and Marie Lafleur on board: Desrosiers tackles complex proceedings with poise, while Lafleur is a fine choice for biologicals and skirmishes under the PM(NOC) Regulations. When flagship products are at stake, David Turgeon steps up to the plate: the global IP group chair thinks strategically and designs results-driven enforcement plans that are easy on the bank balance too. “A brilliant pharmaceutical patent litigator with fantastic client service skills and a dedication to excellence”, Jason Markwell is “an all-round great advocate”.  High-tech ace Marek Nitoslawski brings the heat in transnational disputes and knows how best to ensure that counsel across the world are all on the same page. President of the Intellectual Property Institute of Canada and versatile counsellor Alain Leclerc advises holistically across the patent lifecycle. On the non-contentious front, the firm has a stellar line-up in the form of Serge Lapointe, Mark Penner, Alexandre Abecassis, Johann Gest and Armand Benitah. The business-minded and technically skilled Lapointe has in-depth industry and private practice experience, which informs his validity and infringement opinions. Also in the life sciences, fellow biotechnology maven Penner has the commercialisation of assets down to a T. Electrical engineering instructions are impeccably executed by Abecassis and Gest, who between them have spent over three decades at the patent coalface. Dual-qualified Benitah has a dynamic practice encompassing everything from patents, trademarks and copyrights to industrial designs and trade secrets. As a result, he advises holistically and get companies maximum return on their investments with minimum fuss. Contributing much to the deal side of the practice is Jean-Nicolas Delage, who flexes deep licensing and technology transfer expertise.

Fineberg Ramamoorthy

Demonstrating great composure in complex cases, Neil Fineberg and Kavita Ramamoorthy are cornerstones of vibrant IP litigation boutique Fineberg Ramamoorthy. “Intelligent and strategic”, the pair are “outstanding at what they do and a real pleasure to work with or even against”. Fineberg’s chemistry background and Ramamoorthy’s toxicology doctorate ensure that every argument they present is underpinned by a solid technical understanding. The firm recently unveiled its new signing Judith Robinson, a seasoned advocate distinguished by her exceptional proficiency in cross-border litigation.

Gilbert's LLP 

The “thoughtful and imaginative” group at Gilbert’s is “not afraid to take risks and take on cases where the boundaries of the law need to be pushed. If you need a firm that will invest its all into a case, it is among the best – if not the best”. Namesake and leader of the practice Tim Gilbert bears “the hallmark of creativity”. His complete command of pharmaceutical matters has earned him a prominent position on the Canadian IP scene and he garners glowing notices as a result: “If I know a case needs some strategic manoeuvring, I refer to Tim. He is also very clever and impressive in bringing parties together, guiding them through tough negotiations and bringing about successful conclusions”. “Skilled and pleasant to deal with”, Nisha Anand “also shows a little tooth when necessary, but always in an appropriate way. She is a worthy adversary and a role model to men and women alike”.

Goodmans LLP

“There is absolutely no doubt that the Goodmans team are premier litigators by a long shot.” “It is one of the best firms to come up against in a dispute: its lawyers are always well prepared and their written and oral advocacy is second to none.” Leading the charge are Harry Radomski and Andrew Brodkin, who have unparalleled drug patent trial experience and are “extremely savvy” in managing complex litigation. “Harry is an absolute trailblazer, while Andrew is one of the best orators in Canada. He is a great cross-examiner too, but his real skill is assembling arguments alongside his team.” The praise continues to flow in: “The pair have built up a new generation of leading advocates, including Sandon Shogilev, Jordan Scopa and Ben Hackett. They have a collaborative approach, are gracious when coordinating among counsel and try to minimise disagreements wherever possible.” Radomski, Brodkin and Shogilev have recently been acting for Apotex in an infringement action brought under the PM(NOC) Regulations; while Scopa and Hackett teamed up with the division spearheads to take on Eli Lilly on behalf of Apotex under the same regime. Further contentious firepower comes in the form of Dino Clarizio and Richard Naiberg, who also make light work of prosecution instructions. Clarizio has co-authored two of Canada’s leading patent textbooks and has solid foundations to draw upon; while Naiberg recently went out to bat for Google in an infringement action against Sonos in relation to its beam speaker products.

Gowling WLG

A member of the patent elite, Gowling WLG has a lot to offer patrons, from a wealth of international resources – courtesy of its expansive global network – to a crew of seasoned professionals who can handle the toughest prosecution, litigation and transactional mandates. Life sciences companies seeking watertight patent protection have an abundance of options, including Brian Kingwell, Konrad Sechley, Selena Kim, Susan Tandan, Daniel Polonenko, Omar Nassif and Jennifer Wilkie. Based out of Vancouver, Kingwell has a patented medical device to his name and channels that same creativity in managing Genentech’s international portfolio. Sechley provides easily executable advice to biotech start-ups; while Kim is highly sought after for her keen strategic eye and dexterity. Tandan has been on a roll lately, having helped Autom River Inc to obtain extensive patent protection across every continent for its biodegradable insect trap. Polonenko taps into deep reserves of biotechnology wisdom to provide advice that gets right to the heart of business; he has co-authored 20 scientific publications, co-invented six patent families and spent seven years at executive levels of two biotechnology companies. With over three decades of experience behind him, Nassif is one of the savviest agents in Canada and drafts applications in a way that judges and juries instantly get. Of Wilkie, one client enthuses: “She works with wildly different inventions and really understands what makes each one unique. She has a 100% success rate and her arguments are always clear, concise and well conceived. She has even managed to overturn decisions to get patents granted and cannot be recommended enough.” On the high-tech side, James Longwell, Neil Henderson, Brian Lee, Grant Tisdall and Roch Ripley are all equally as distinguished as their life sciences colleagues. The technically brilliant Longwell has been prosecuting multiple applications for Geeq Corporation relating to its cutting-edge blockchain technology, securing patent protection in the United States and internationally. Henderson “always provides pragmatic advice and really understands the need to leverage intangible assets to grow a business and turn it into a financial win. His ability to think outside of the box, come up with creative solutions and stay on top of portfolios is most impressive”. Colleague Lee likewise garners positive feedback: “He is one of the very rare patent attorneys who can identify patentable opportunities and effectively compile and submit applications that have a high success rate. Brian also has an excellent ability to capture the essence of a patent in way that makes sense to non-technical executive management.” An exemplary agent with the versatility to handle a wide range of technologies, Tisdall is a fine choice for strategic advice, international filings and the ironing out of R&D agreements. IT and software companies in search of a practitioner who “excels at filing applications and managing international portfolios, and provides practical, timely and cost-competitive services that differentiate him from a sea of other service providers”, should turn to Ripley. There is also no shortage of courtroom muscle at Gowling WLG, and Michael Crichton and Christopher Van Barr are two of the top names on the fight card. The pair recently represented LG Electronics in an infringement action involving mobile phone handover technology and SEPs – one of the only SEP cases ever litigated in Canada. Crichton also linked up with IAM Patent 1000 newcomer Nelson Godfrey to counsel BC Hydro in an infringement suit relating to methods for detecting atypical electricity consumption and the theft of electricity. A prominent figure in the pharmaceutical world, Anthony Creber is a trial wizard who has recently been acting for Astrellas Pharma in enforcing three of its patents against Sandoz. Colleague Ronald Dimock also sets the gold standard and has been pulling all the right levers to carry the day for Henkel Corporation against GEMAK Trust. He also appeared as an expert witness for Sanofi-Aventis. Patrick Stewart Smith has “a level of expertise and understanding of complex chemistry that go beyond the norm. He responds to issues with clarity and conviction, anticipates any hiccups and acts proactively to ensure his clients’ positions are well supported”. Joining them in the guide this year is John Norman, whose “robust combination of skill, experience and dedication is most reassuring. His temperament and demeanour are finely tuned to the needs of the litigation lifecycle, and he has a great disposition when honing strategies too”. Transactions ace Anita Nador understands the business value of intellectual property and puts commercially on-point strategies in place to help clients maximise their investments.

A tenacious advocate who puts in eloquent performances, she has proven her mettle in technically complex proceedings time and time again. Joining her in the guide this year is Cynthia Tape, whose pathology PhD and commercial nous make her a valuable resource for universities and industry heavyweights alike.

Marks & Clerk

“Marks & Clerk has top-quality prosecution services and delivers legal advice that fits in with our organisation and its infrastructure,” enthuses one patron. “It is difficult to find foreign representatives who can provide a really seamless service when it comes to international filings, but you can count on Marks & Clerk to take care of it all.” Operating out of the Ottawa branch, Ian Clark, Hetal Kushwaha and Jean-Charles Grégoire coordinate with clients, examiners and other counsel to ensure that large-scale mandates are executed with finesse. A former research associate at the Institute for Biological Sciences at the National Research Council of Canada, Clark is the first point of call for life sciences matters; while Kushwaha is lauded for her “quick response times, customer-centricity and undivided attention to clients’ needs”. Astute in his approach to complex legal issues that have not yet been tested in Canada, Grégoire “is practical, deciphers the law and presents it in a way that makes the path forward very clear. He is excellent to work with”. Over in Toronto, David Ruston navigates a variety of engineering disciplines, including oil and gas technologies, medical imaging and even the aerospace industry. Freedom-to-operate searches and validity opinions are his fortes. The outfit’s contentious offering is heating up too, with the arrival of Bereskin & Parr’s Amrita V Singh. “Industrious and hardworking, Amrita is a go-getter who is always moving the ball forward.” The “practical, thoughtful problem solver and sharp litigator” is “a natural leader who is well respected by her peers.”

McCarthy Tétrault LLP

The McCarthy Tétrault team “is fantastic and does truly wonderful work; they are smart, write incredibly well and produce excellent arguments before the judges; and most importantly, they get results. They have a solid grasp of the technologies and patents they work with, and excel at balancing cases that take place in multiple jurisdictions”. Providing a wraparound patent service, the outfit is a premier destination for life sciences, telecommunications and oil and gas entities looking to procure, enforce or monetise their assets. National IP litigation group chair Steven Mason is “the model of integrity, attention to detail and client dedication”. He and David Tait recently took the lead on multiple actions under the PM(NOC) Regulations for Merck concerning generic versions of three of its products. In the words of one patron: “David is a great litigator who really listens to us and gives tailored advice that is adapted to our business needs; his strategies really go a long way. I think the world of him and his team.” Flanking them is IAM Patent 1000 newcomer and “fantastic lawyer” Rebecca Crane, who stands out for her “scientific knowledge and ability to work effectively with in-house experts”. Bell, TELUS and Rogers Communications have the ear of Fiona Legere, who “conducts some of the most concise and impressive cross-examinations anyone has seen”, according to one peer. Within the petroleum industry, Timothy St John Ellam and Steven Tanner have been doing some great stuff, including representing MEG Energy in a dispute against Crude Solutions that has received nationwide attention. Recommended on both the prosecution and transactions tables, Lisa Melanson, Vincent Kam-Sun Yip and Alfred Macchione are the perfect fit for all things non-contentious. Melanson is a go-to for effective cross-border strategies and global portfolios advice; and Kam-Sun Yip flawlessly navigates complex deals, such as Morningstar Inc’s acquisition of financial-planning and risk-profiling software firm PlanPlus Global. “Bright and up to date on the latest regulatory developments within AI and machine learning”, Macchione “has mastered writing patent claims that get maximum coverage and is extremely skilled at dealing with counterclaims too”. Overseeing the national technology law unit and co-leading the fintech group, Christine Ing has a flair for strategic IP development, licensing and technology transfers.

Merizzi Ramsbottom & Forster 

A go-to for any prosecution needs, Merizzi Ramsbottom & Forster “has the expertise and genuine creativity to prepare patent applications in emerging and novel disciplines such as biotechnology. Its practitioners know how to translate inventions into well-drafted claims and have the foresight to incorporate details that can be used down the line when filing other applications in similar fields”. In Ottawa, André Merizzi is “a master at what he does. He has a constructive approach to drafting, covering subject matter as broadly as possible while focusing in on claims that are commercially useful. He is friendly, skilled at handling complex technologies, provides valuable insight and recommendations and keeps communication lines open. Simply, Andre is one of the best”. Making his IAM Patent 1000 debut this year, the “responsive and highly organised” James Ramsbottom operates out of Victoria: “James thinks critically and his combination of scientific knowledge and artful patent construction is rare to find.”

Norton Rose Fulbright

A comprehensive offering, widespread domestic coverage – it has outposts in Calgary, Montreal, Ottawa, Quebec, Toronto and Vancouver – and a mighty international network make Norton Rose Fulbright more than just an able running mate to some of the world’s most prominent life sciences and pharmaceutical companies. This year has seen it battle it out in some headline-grabbing cases – for instance, it acted for Pfizer in the first action to go to trial under the PM(NOC) Regulations and represented Novo Nordisk in the first patent infringement action commenced under Section 8.2 of the regulations. Taking the lead on the former was Mark Davis, a “sharp, first-class litigator who is relentless in advocating for his clients. He is personable, easy to work with and gives practical advice”. Another major contributor to the firm’s success rates is Jordana Sanft, whose “extensive experience litigating pharmaceutical disputes is clearly reflected in her solid legal advice. She is super-knowledgeable, gives excellent strategic guidance and always thinks of the big picture and the business implications behind her suggestions. Jordana masters complicated technologies and works really well with expert witnesses, while showing a willingness to take the time to explain tricky procedural issues too”. Allyson Whyte Nowak and Amy Grenon also receive glowing feedback: “Allyson provides excellent advice, strategic counsel and solutions that are very thoughtful and aligned with a company’s overall objectives, while maintaining an outstanding level of client service.” “Amy is a fantastic litigator – she effectively and persuasively communicates the essence of complex technologies to the court. Her presentations are smooth and exude confidence, and she remains steady and focused during objections too. To top it off, she can answer any question at a moment’s notice, thanks to her instant recall of every case she works on.” Bringing great regulatory insight to the table, meanwhile, is Brian Daley, who prevailed for I-MED Pharma against TearLab Corporation. IAM Patent 1000 newcomer Kristin Wall makes her debut in the guide on the back of stellar work for GlaxoSmithKline: she fought the corner of the pharmaceutical giant in the first court challenge under Canada’s newly enacted Certificate of Supplementary Protection Regulations. Over on the prosecution wing, Sébastien Clark and Maya Medeiros are the main attractions. A highly regarded scientific adviser in contentious proceedings, Clark is also a superb drafter and strategic counsellor – as evidenced by his work for Bombardier, which covers its entire global portfolio. Of Medeiros, one patron enthuses: “She truly goes above and beyond to support us in research and collaboration products. Her legal talent and client-centricity are exceptional: she is committed to understanding our business, technology and objectives, and always bears them in mind when giving advice.” National IP chair Jung-Kay Chiu is an extremely versatile operator who has recently been working with Johnson & Johnson on its patent strategy.

Osler, Hoskin & Harcourt LLP 

Ascending to the gold tier this year, Osler Hoskin & Harcourt is going gangbusters in the life sciences right now, securing dozens of client wins and acting on some super-impressive mandates. It recently brought home several victories for Teva and has also been representing Samsung Bioepis against Fresenius Kabi. These success stories were due in no small part to J Bradley White, who “runs a top-flight and successful shop. He is one of Canada’s leading and most respected litigators, and deserves only the highest praise”. He regularly pairs up with Nathaniel Lipkus to form an unstoppable duo. An “accomplished trial lawyer with a keen intellect and a strong team player in complex multi-party proceedings”, Lipkis “is always well prepared and super-courteous too”. Vincent M de Grandpré and IAM Patent 1000 newcomer Geoffrey Langen make up the rest of the litigation strike force. All four have been coordinating seamlessly to represent Mylan Pharmaceuticals against Eli Lilly, AstraZeneca, Amgen and Takeda. De Grandpré earns further plaudits as “counsel of choice for complex cases and a smart, strategic lawyer who is very comfortable thinking on his feet”. The strengths of transactions whizz W Lee Webster include “his technical expertise, clear and articulate communication, and attention to detail. In negotiations, he is persuasive, knows how to read the room and asserts himself in a way that gets the conversation back on track. Lee really protects his clients’ best interests and ensures they are protected in both the short and long term”.

PCK Perry + Currier Inc

A wall-to-wall service, technically diverse attorneys, advanced in-house AI technology and a transparent flat-fee structure are just some of the ways in which PCK Intellectual Property differentiates itself from its competitors. The innovative, technologically savvy outfit is always seeking to maximise efficiency without compromising on quality, to ensure that patrons have the best possible experience when they engage it. Co-founders Stephen Perry and Andrew Currier drive the practice forward. Perry acquits himself with distinction when devising strategies that enhance the portfolios of high-tech companies; while Currier understands the commercial side of intellectual property and gives business-minded advice that ensures companies reap maximum rewards on their investments. The pair have an intimate understanding of the law too, as the co-authors of one of Canada’s leading patent law textbooks.

Ridout & Maybee LLP

Having retained its stronghold on the Canadian IP scene for more than 120 years, Ridout & Maybee has intimate institutional knowledge of how the country’s laws and policies have evolved and the foresight to spot where potential changes may arise. This all translates into incisive advice that considers the long term as a matter of course. Mechanical engineer Ken Bousfield is one of its shining stars and can be counted on for astute validity and freedom-to-operate opinions.


Founded in 1892, ROBIC has its roots deeply embedded in the country’s legal landscape; but rather than stagnating, it has kept its offering fresh and vibrant with new services – the latest one focusing on cybersecurity in light of the constantly evolving technological scene. Collectively, the team covers a lot of ground to provide “creative and pragmatic solutions to complex prosecution problems”; but the high-tech, engineering and material sciences arenas are where it truly shines. “Clear and timely advice” is dispensed by molecular biologist Gabrielle Moisan; while physicist Isabelle Girard is a natural choice for those looking to develop their portfolios. Metallurgy maestros Nathalie Jodoin and Dominique Pomerleau are meticulous in drafting applications and can identify the optimum route to grant. In the high-tech realm, strategic counsellor Louis-Pierre Gravelle is a safe pair of hands for companies keen to strengthen their market positions; while mechanical engineer David Enciso is highly sought after for his perspicacious patentability and validity opinions. Montreal is also home to a cracking litigation and licensing practice, courtesy of tenacious advocate Bob Sotiriadis and smooth negotiator François Painchaud.

Rowand LLP

Rowand’s USPs include an innovation-driven service, a refined understanding of the high-tech industry and the ability to cater to clients at the cutting edge of their respective fields. For instance, more than 80% of the applications it sees through to grant are for software-implemented inventions; and its latest highlights have been on behalf of A-listers such as BlackBerry, Rogers Communications and Trading Technologies International. For entrepreneurs that wish to leverage their creations and gain a solid foothold in the market, Fraser Rowand is an outstanding choice. He manages portfolios effectively, drives business value and obtains robust patent protection not only in Canada, but internationally too. Fellow partner and electrical engineer Jeff Tracey is not one to shy away from pushing legal boundaries and has a rare facility for the protection of blockchain inventions.

Smart & Biggar 

Unanimously hailed by the market as “a first-class firm that excels at the technical aspects of patent prosecution”, Smart & Bigger is one of Canada’s most prolific filers on behalf of industry giants from all over the world. It is also a formidable force in enforcement scenarios and has chalked up several significant wins over the past year; while its transactions crew is regularly called upon to broker lucrative global licensing deals. On the non-contentious side, managing partner Matthew Zischka sets the tone from the top. The electronic engineer is comfortable acting across a range of technologies and really hits his stride when advising companies on how to make best use of their assets through business-driven strategies. Operating within the same field, John Knox and Allan Brett bring valuable industry experience to the mix. Knox has prosecuted applications in almost every country in the world and has international procedures on lock; while Brett has seen hundreds of originating patent applications through to grant and is a vital resource for those looking to protect electronic or computer-related inventions. Joining them in the guide this year are Elliott Simcoe and Brigide Mattar. Electrical and mechanical practice group leader Simcoe is a repository of trust for blue-chip innovators keen to maximise the return on their investments; while trained computer engineer Mattar is a font of wisdom when it comes to AI. In the life sciences, Daphne Lainson, David Schwartz and Mark Pidkowich are a cut above. Firm chair Lainson impresses with her regulatory know-how and ability to distil legal complexities into readable reports; Schwartz is a known thought leader who has the PM(NOC) Regulations down pat; and Pidkowich brings added value by designing strategies that meet clients’ immediate, mid and long-term goals. The litigation squad also sees some new additions to the rankings this year, in the form of Sheldon Hamilton and Jeremy Want. A compelling advocate, Hamilton has over 25 years of experience and a down-to-earth style which make him highly effective. Immensely seasoned in trials concerning the quantification of damages, Want recently secured a C$650 million damages settlement for Dow Chemical – the largest reported award in a Canadian infringement case. For this, he teamed up with Steven Garland, an “exceptionally strong litigator” who knows how to turn around the trickiest of cases. He recently obtained a rare interlocutory injunction from the Federal Court on behalf of Exaltexx. Similarly, François Guay also comes in for praise as a “dynamic lawyer” – as his fine work for Canadian National Railway bears out, that comes as no surprise. The case was of utmost importance, and the company’s successful appeal reaffirmed the long-established practice of granting protective orders to parties involved in IP litigation before the Federal Court in Canada and reinforced an important feature of the discovery process. Yoon Kang, Nancy Pei and Gunars Gaikis are the names to note for skirmishes in the pharmaceutical sector. A repository of trust for her clients, Kang is a clear-thinking counsellor and tactical litigator with an excellent hit rate. Success on behalf of life sciences innovators is also a daily thing for Pei, whose wisdom on diverse regulatory and commercial matters informs a sophisticated approach to cases. A pre-eminent lawyer, Gaikis has seen and done it all in high-stakes proceedings and thinks up strategies that get life sciences companies out of tricky situations without a hitch. The energy and petroleum industries are happy hunting grounds for Evan Nuttall and Ryan Evans, who dish out sophisticated advice and always have the end game in mind. The same is true of the ensemble’s transactions unit – home to Alistair Simpson, Sanjay Goorachurn, Stephan Georgiev and Theodore Sum. Simpson and Goorachurn are innovative in their approach to structuring deals and work closely with the C-suite to draft licensing agreements that fit like a glove. Georgiev is hailed as a “renowned and super-experienced strategist”; while Sum comes in for praise as a “top-notch practitioner with an unsurpassed legal mind. He is also extremely diligent and ensures every client – big or small – receives the best advice”.

Stikeman Elliott LLP

A new name in the IAM Patent 1000 this year, Stikeman Elliott makes its debut on the back of stellar work examples and an offering that covers all bases to help companies innovate, enforce their rights or carve out market share. As an example, the group prosecutes applications for Edward Lifesciences Corporation, Accuweather and Lyft. Spearheading the practice is Jonathan Auerbach, an elevated strategic thinker who understands that intellectual property does not operate in a vacuum and is always alive to the commercial interests of his patrons.

Torys LLP

“It is always a pleasure to come up against Torys,” enthuses one peer. “Its lawyers are always well prepared and present comprehensive and refined arguments in court.” The side is also lauded for its precision prosecution practice; unique insight into the pharmaceutical, biotechnology and cannabis industries; and ample regulatory expertise. More recently, it has been venturing further into the technology space, having just launched an emerging technologies and venture capital practice group. Stand-out litigators Andrew Bernstein and Andrew Shaughnessy are “exceptional” and are counsel of choice to leading players such as Eisai Co and Catalyst Pharmaceuticals. Shaunghnessy in particular is hailed as “shrewd, practical and highly knowledgeable in all areas of patent disputes. He is instrumental when assessing risks, devising strategies and figuring out the best course of action”. Teaming up with them to represent Amgen in two actions under the PM(NOC) Regulations against Mylan is Yael Bienenstock, a “fair and effective advocate” who makes her IAM Patent 1000 debut this year. On the prosecution side, Teresa Reguly and MaryAnne Arnoldo also make their first appearance in the guide. “Teresa is an invaluable resource – no one can compare to her thoughtfulness, level of strategic thinking and timely execution of instructions.” Arnolodo also garners plaudits: “MaryAnne is very knowledgeable about the agricultural and biotechnology industries, and provides meaningful strategic guidance that considers business needs and is cost effective too. She has also shown an excellent command of the laws and rules, and – importantly – the ability to use that to solve complicated challenges through insightful analysis.” For Procter & Gamble, no one else can prosecute quite as well as their preferred counsel, Eileen McMahon and Edward Fan. A superior strategist, McMahon provides first-class guidance on the development and monetisation of portfolios; while Fan is “super-professional, quick to respond, and produces work of a consistently high quality”.

Other recommended experts

Blending great technical skill with deep substantive patent law knowledge and superb advocacy skills, the dual-qualified Michael Adams is the full package. He operates out of Riches McKenzie & Herbert LLP. In Montreal, Benoît & Côté’s Marc Benoît “has established a powerful practice and is someone I am always eager to refer to,” reports one peer. He and co-founder France Côté are dedicated to clients and offer strategic, commercial advice that protects intellectual property and mitigates risk. Alaka Chatterjee, a chemistry expert at Vanguard IP LLP, astutely manages worldwide portfolios for research institutes and global giants, and forges long-term relationships with patrons. A founding member of Deeth Williams Wall, technology ace Douglas Deeth comes equipped with over four decades of experience and has a gravitas that is hard to find. He and fellow founder Gervas Wall know all the best plays to get high-rolling licensing deals inked. Adapt IP Law’s Peter Elyjiw receives spirited praise: “The value Peter provides with his services is tremendous – you can completely trust him to do the job at the same level you would get at larger law firms, but without the pomp and the price tag. He is mindful of time, explains timelines clearly and translates the details and nuances of inventions extremely well. Basically, Peter is unreservedly recommended to start-ups, large corporations and anything in between.” Eduardo Fonseca of Moffat & Co Patent & Trademark Agents leverages insight gained at a Brazilian firm to serve as a key point of contact for Latin American life sciences concerns which have trained their attention on Canadian horizons, and vice versa. Recently departing Rouse in the United Arab Emirates to set up his own boutique FILFIL IP in Canada, Rami Filfil impresses with his friendly approach, strong scientific background and ability to translate technical data into a successful patent application in record time. Rami presents insightful recommendations informed by a refined understanding of international patent legislation and is adept at securing cast-iron protection on a global scale. Based at his eponymous boutique, Brian Gray stands out for the breadth of his expertise and his willingness to go the distance, whether that be in court or at the negotiating table. At Farris, Vaughan, Wills & Murphy LLP, James Hatton is a widely respected biotech lawyer who does much outside of his practice to support the life sciences community. Heer Law’s Christopher Heer is a repository of trust to software companies and academic institutions seeking to protect their computer-implemented inventions. One of his highlights includes successfully drafting, prosecuting and obtaining two US patents relating to deep neural networks and computer vision for the Governing Council of the University of Toronto. Flying the flag of Oyen Wiggs Green & Mutala, Gavin Manning has spent over two decades obtaining robust patent protection and commercialising assets for technology start-ups and international corporations. Life science sage Serge Shahinian provides inspiring leadership to Lavery Lawyers’ IP group and has a flair for bringing added value to the portfolios of biotechnology companies. Kevin Shipley is “a fantastic IP professional with a thorough knowledge of patent law and practice in both Canada and the United States. He is a very effective communicator, and his framing of the relevant issues for discussion and analysis thereof is highly developed and ideal for solving complex issues”. He practises at Folger, Rubinoff LLP. A preferred choice for prosecution, Jenna Wilson of Wilson Lue enjoys working in areas that push the limits of existing patent law – in particular, within the biotechnology and IT sectors. At Blaney McMurtry, Nicholas Wong knows how to build strong portfolios from the ground up, but maintains a cracking litigation practice too. In the words of one peer: “Even when we were up against each other, Nick just made life easier for everyone involved, which is a fantastic quality to have.”
