The Canadian patent regime was overhauled in 2019 with the entry into force of the new Patent Rules and amendments to the Patent Act on 30 October. The revisions have streamlined the country’s laws and aligned them with the Patent Law Treaty, as well as allowing for international harmonisation. Key changes include reduced direct filing requirements; shortened deadlines for examination requests; and the possibility for the restoration of priority. The nation’s practitioners are now hard at work bringing clients up to speed on the legislative shake-up, to help them avail of new opportunities and ensure that operations are not impeded in any way. Meanwhile, Canada’s booming cannabis industry has been up and running for a year, and several firms have expanded their practices to cater for new instructions from that direction. Other sectors running hot right now include biologics, fintech and artificial intelligence (AI): practitioners report increased activity across all three.

Borden Ladner Gervais (BLG) has stacked up one of the most technically diverse benches in Canada and has the wherewithal to prosecute any application with finesse and precision. Clients in the life sciences have struck gold, as David Nauman, Mark Vickers, Scott Pundsack, Jennifer Raoul, Kathleen Marsman, and Graeme Boocock are all eminent experts in their fields. “When unexpected situations arise, Nauman does not hesitate to jump in and is key to developing a winning strategy”; he recently worked alongside Vickers on two successful Patent Appeal Board hearings for Coopervision International Holding Company. “Vickers has the complete skillset for a strong agent, but one of his key strengths is communication. He facilitates good discussions which then lead to securing optimum asset protection.” Senior counsel Pundsack acquits himself with distinction on re-examination and re-issue applications. “Biotech superstar Raoul deftly handles complex cases”; while Marsman is a favourite among pharmaceutical companies. “Keen, sharp and detail oriented, Graeme can reorganise complex ideas and leaves no stone unturned in his analyses. He is conscious of commercial concerns and goes out of his way to quell any insecurities. His knowledge is up to the minute and he has quickly established himself as a leading light in the fields of biology and chemistry.” On the high-technology front, Louis Allard, Curtis Behmann and Brandon Evenson are the A-listers. A former researcher with several patents to his name, “Allard is a true professional who is consistently dedicated to producing first-class work. His ability to convert technical data into an application and extract all the relevant information is exceptional. To top it off, his track record is superb”. Having worked as a senior examiner at the Canadian Intellectual Property Office, Behmann is a perceptive strategist with an insider’s view of the patent grant process. “Clever, conscientious and a great guy all around, Evenson always adds value and is more of a partner than external counsel. His knowledge of the subject matter is immense and he can transfer that clearly to provide sound advice to start-ups and multinationals.” Regional managers of Vancouver and Ottawa respectively, Geoffrey de Kleine and Andrew Sojonky are the resident mechanical wizards. Of Sojonky, one client comments: “His natural entrepreneurial mindset makes him extremely personable and he always puts in the extra effort to meet face to face. Everything he does, he does to the highest standard.” The BLG group also has the capability to protect and enforce assets, with polished litigators Kevin LaRoche, Jamie Mills, Chantal Saunders and Beverly Moore actively looking to nip infringements in the bud. La Roche thrives at unravelling the intricacies of high-tech disputes; Mills blends his IP and regulatory know-how to bring life sciences spats to a favourable close; Saunders has a refined understanding of the Patented Medicines (Notice of Compliance) Regulations and often links up with Mills on pharmaceutical clashes; and IAM Patent 1000 newcomer Moore fights tooth and nail for biotechnology companies.

Patent procurement and monetisation come naturally to Chari, “a responsive, organised and technical practitioner who pays great attention to detail”.  For skilful drafting and prosecution in the software, electrical and mechanical fields, Slaney is the first port of call.

DLA Piper

DLA Piper meets and exceeds the needs of innovators of all stripes from five locations across Canada; the firm’s vast international network is a particular boon to those seeking joined-up global support. Despite some recent losses, the practice is as strong as ever – especially with Bruce Stratton at the helm. Stratton’s technical background gives him an extra edge when devising arguments that will carry the day in IT disputes. “Well known and respected, Alan Macek is always up to date on the latest developments in his field.” He knocks it out of the park in cross-border proceedings involving electrical and computer-related technology.


“Incredible service quality and super-responsive” is the verdict on business law firm Fasken. One of the largest outfits in the country, it has over 700 lawyers in seven Canadian offices and additional bases in Beijing, Johannesburg and London, delivering holistic patent protection that makes business sense. Julie Desrosiers and Marie Lafleur are the main attractions for those facing pharmaceutical litigation. “Super-smart and always a winner, Desrosiers is the full package”; while Lafleur has quickly cemented her reputation as an expert in biosimilar disputes. Another biologic drugs ace is David Turgeon, who often sits as lead counsel in sprawling disputes and comes up with time and cost-efficient strategies. Transnational clashes are skilfully handled by high-tech whizz Marek Nitoslawski, whose solutions are as innovative as the clients he assists. Fasken recently added to its contentious firepower by welcoming Jason Markwell, who is active in biotechnology, telecommunications as well as oil and gas; his “dedication to excellence” is on show in his every move. Another new name on the team, Alain Leclerc effortlessly traverses the contentious/non-contentious divide and currently sits as president of the Intellectual Property Institute of Canada. Meanwhile, Fasken’s all-star line-up of Serge Lapointe, Mark Penner, Alexandre Abecassis, Johann Gest and Armand Benitah has prosecution on lock. In the life sciences, Lapointe is the man to call for due diligence investigations. Penner “is a real problem solver who dispenses articulate and succinct advice” in technology-heavy industries. For electrical engineering mind-benders, Abecassis and Gest draw on deep reserves of knowledge to protect innovations and build up portfolios. A lawyer and a patent agent, Benitah has a bird’s-eye view of asset protection and value creation in the mechanical and electromechanical sectors. Transactional maven Jean-Nicolas Delage has an affinity for the fine print of technology transfer agreements and an understanding of standard-essential patents.

The Toronto-based lawyers at Gilbert’s operate adroitly at the confluence of law, science and business, consistently achieving positive outcomes in must-win litigation involving cutting-edge technologies. The firm has a redoubtable leader in Tim Gilbert, who never advises in a vacuum and is always alive to the commercial realities of his clients. Gilbert spends most of his time battling it out in court, but also looks to maximise asset value through lucrative licensing deals. IAM Patent 1000 newcomer Nisha Anand has a doctorate in molecular biology, genetics and cancer, and “can explain complex legal areas clearly and quickly”. Her technical and regulatory nous proves invaluable when unpicking the knots of cross-border pharmaceutical disputes.

Goodmans LLP

“Widely renowned as best in class for major patent litigation, Goodmans zealously advocates for its clients on every occasion and is extremely savvy in court. The firm garners immense respect for its collaborative nature with opposing counsel to minimise fuss and unnecessary disagreements. Simply put, there is Goodmans and then there is the rest.” The squad is impressive from top to bottom. Inspired leader Harry Radomski “has achieved more success in high-stakes pharmaceutical cases than any other lawyer at the Bar. Intelligent, strategic and extremely hardworking, he has built up an excellent team and a loyal following.” “Excellent cross-examiner and trial lawyer” Andrew Brodkin “has extraordinary advocacy skills. He is really persuasive and is without question, among the top tier of IP litigators in Canada”. Dino Clarizio and Richard Naiberg also perform outstandingly in disputes, while putting in a strong showing on prosecution too: “They are really well respected and provide great strategic advice in complex matters.” Patrons are full of praise for Ben Hackett and IAM Patent 1000 debutant Jordan Scopa, “who are emerging as the next generation of patent litigators. The pair are extremely effective, with a great command of procedural and substantive law”.

Gowling WLG 

Gowling WLG takes a comprehensive approach to intellectual property: with the best and the brightest prosecutors, litigators and transactional specialists on tap, clients sleep soundly knowing their crown-jewel assets are safe. Companies in the life sciences look to Konrad Sechley, Susan Tandan, Brian Kingwell, Daniel Polonenko and Selena Kim for robust patent protection.

Polonenko is a font of biotechnology wisdom, having co-authored 20 scientific publications and several book chapters, and co-invented six issued patent families. The first woman in Canada to have achieved the certified specialist designation for patent law granted by the Law Society of Upper Canada, Kim is widely respected in her field. “She is really impressive, kind and humble. Selena takes the time to patiently guide you through the process and is always on hand to answer any questions while giving practical and informed advice. Working with her made the ride a whole lot smoother.” The side was strengthened with the arrival of Omar Nassif, whose technical prowess takes him all over Canada and beyond. Meticulous drafting and timely filings are also guaranteed by the high-tech bench, comprising Brian Lee, Grant Tisdall, Neil Henderson and James Longwell. Most active in fuel cell technologies, Lee infuses his advice with insight gleaned from a previous in-house position and a stint as director of the Canadian Hydrogen and Fuel Cell Association. Tisdall specialises in developing bespoke innovation programmes and often works closely with Russian technology companies to help boost their global portfolios. Henderson and Longwell also enjoy an international practice, with a particular focus on the Japanese and Chinese markets respectively. When the going gets tough, Anthony Creber, Michael Crichton, Christopher Van Barr, Patrick Stewart Smith and Ronald Dimock get drafted in to fight the good fight. Seasoned courtroom veteran Creber is a familiar face at the Supreme Court and has chalked up numerous victories over his 35-year career. Lantech, Seedlings and LG Electronics count on IP litigation and strategy division lead Crichton to deliver in convoluted proceedings. Pharmaceutical heavyweights Bayer and Takeda have the ear of Van Barr, a superb first-chair litigator. Spearheading Calgary’s IP group, Smith “is immensely experienced before the courts and has extensive chemistry knowledge. He responds to the needs of his clientele and communicates really well”. The firm also brought on gold-ranked Ronald Dimock from DLA Piper, who knows everything there is to know about patent law after four decades of litigating before the Federal and Supreme Courts.

McCarthy Tétrault LLP

McCarthy Tétrault’s tailored patent service has everything needed to assist emerging companies and well-established multinational corporations in their acquisition, enforcement and commercialisation efforts. Chair of the national IP litigation group Steven Mason “impresses with his strategies, courtroom manner and attention to detail”. He recently put in a virtuoso performance for Bell Canada in three ongoing infringement actions, one of which may be making its way to the Supreme Court. Mason often links up with David Tait on bet-the-company pharmaceutical litigation: the pair have taken on several mandates for Bristol-Myers Squibb Company and Akebia Therapeutics. Life sciences devotee Fiona Legere makes her first appearance in the IAM Patent 1000 this year. Armed with a degree in biochemistry, Legere knows the lie of the land and expertly coordinates multi-jurisdictional suits. Timothy St John Ellam oversees the oil and gas litigation group alongside Steven Tanner. The duo recently did battle for Aux Sable in a matter that received nationwide attention from academics and practitioners.

Macchione is lauded for his “in-depth knowledge, cooperative approach and flexibility. Alfred is really professional, able to work to tight-deadlines and dispenses internationally minded advice. He goes beyond expectations and is truly an extension of the businesses he works with”. Another worldly-wise practitioner, Melanson looks after the firm’s IP strategy initiative and has a fine-grained understanding of the pharmaceutical/regulatory interface. Smooth negotiator Yip can get tricky applications through to grant and is a strong ally for complex licensing agreements. National IT law and fintech co-lead Christine Ing has the technical processing power needed for the most intricate deals.

The practitioners are responsive, timely in their responses and offer advice that is always commercially valuable.” Working in the upper echelons of his profession, J Bradley White straddles the contentious/non-contentious divide with poise. “He has the unique ability to break down complex matters into easily understandable chunks and never sugar-coats the truth. Bradley is an excellent advocate before the courts and addresses any concerns or suggestions in real time.” Litigating alongside him on behalf of Teva is the “diligent and smart Vincent M de Grandpré, who has a knack for defining a patent’s position in infringement proceedings.” “Super-thorough and professional, Nathaniel Lipkus is doing some great stuff” in the heavily regulated industries. The transactions practice is flourishing under W Lee Webster: “He ensures that business interests are protected both short and long term through his thorough analyses, negotiation skills and ability to strongly represent the companies he assists.”

PCK Intellectual Property 

“Approachable and responsive, with an all-encompassing knowledge base” is how the professionals at PCK are described.
