The introduction of the specialised Patent and Market Court in late 2016 brought hopes of an improvement in both the speed and quality of decision making in IP infringement cases; while it is still early days, reflecting on 2017 practitioners feel that Sweden has already become a more attractive jurisdiction for patent litigation. Looking at 2018, Sweden has good economic growth prospects – the best of any Scandinavian country – which has put patent professionals in a positive frame of mind; a start-up boom in the financial technology and clean technology industries is just one thing contributing to the market’s dynamism. Uncertainty regarding the entry into force of the Unified Patent Court is, on the other hand, a cause of consternation, particularly as Sweden is set to be home to a regional division of the court.

Advokatbyrån Gulliksson

With a commercial orientation and the niche expertise of a patent boutique, Gulliksson houses both litigators and patent attorneys under one roof and possesses a “knowledgeable, experienced and productive” combination of technical and legal knowledge. Having made an early commitment to battling on the generic side of pharmaceutical disputes, it enjoys the loyalty of major players including Teva and Sandoz; the quality of this following is mirrored in the telecoms, electronics and consumer goods fields. “When the going gets tough, Mattias Malmstedt steps up to the plate.” One of Sweden’s best litigators, he is a preferred collaborator for foreign associates in cross-border work. Armed with a technical background, he is an “all-in-one solution to any problem; his work is of the highest quality across the board. He calls on every tool in his box, summoning creative solutions to any challenge and deftly anticipating his opponent’s next move”. “Cementing its solid position on the market”, the outfit has brought on board life sciences doyen Magnus Dahlman. “Magnus hasn’t been there long”, one peer remarks, “but he has already worked with us in litigation on numerous occasions as well as having been an instrumental adviser to his clients on the commercial aspects of their businesses”.

Advokatfirman Delphi

Advokatfirman Delphi’s IP practice showcases the powerful skills of its attorneys at law, who are active in both contentious and non-contentious matters. Strengthening its offering with three new associates over the last 18 months, the set is renowned for its level-headed supervision of agreements between major rights holders. With regulatory and commercial know-how availble at any time via its corporate, competition and M&A departments, licensing, portfolio acquisition and other IP-intensive agreements are handled with the utmost ease and professionalism. A Delphi partner for over a decade, Henrik Bengtsson is in a good position to answer initial inquiries.

Advokatfirman Lindahl

Substantial general practice outfit Lindahl boasts an IP set responsible for a significant portion of the country’s contentious caseload. “Its lawyers are excellent at what they do, particularly in the courtroom.” As a renowned commercial practice too, it boasts an impressive capacity for handling transactional instructions. Among its excellent individuals, Jonas Westerberg “deserves his place in the rankings. A strong player in pharmaceutical matters, especially where regulatory issues are involved”, he is singled out for his talents in litigation.


“In a conflict, we would have no problem recommending AWA”, confides one peer, echoing the market’s wider confidence in “one of Scandinavia’s largest, most well-trained and professional IP sets”. “No matter who’s in charge, the output remains consistent” thanks to the efforts of Julia Mannesson, a mentor to the group’s trainees and a rights protection champion. She has recently been prosecuting patents for Skanska Sverige. Sören Giver is preparing the next generation to take over the crew’s renowned toil before the European Patent Office (EPO). A skilled IP strategist, he maintains a network of clients and associates across Europe and the United States. The same applies for Niklas Mattsson, “an excellent professional and a pleasure to work with”, who is in demand for his ability to secure supplementary protection certificates. Dispersed across Sweden, the firm’s specialists in opposition and appeal proceedings – Mikael Henriksson, Urban Lind and Inga-Lill Andersson – have established an impressive profile. Henriksson has spent nearly two decades on the Awapatent team and he truly is a biochemical savant, adroit in oral proceedings and a dab hand in less heated matters too. Lind takes point on the specialist US law division, transposing his European and US know-how into added value. Andersson has drummed up an influx of new business; the chemical maven’s remarkable IP skills, commercial outlook and pioneering attitude make her a must-hire attorney. “Any discussion of the firm’s dominance in prosecution is incomplete without Mattias Pierrou”, who makes his debut in the IAM Patent 1000 this year. Taking the lead on portfolio management for major electronics devotees over the last 18 months, “the seasoned prosecutor is highly valued by his following”; he applies his comprehensive knowledge in the optics field for display technology manufacturer BOE Technology. “An experienced litigator”, Peter Kenamets masterminds the set’s patent operations. A dominant force in the contentious realm, he showcases his foresight and strategy on behalf of the European operations of major multinationals in myriad industries. Kenamets turns to renowned lawyer Martin Tranälv to put any doubts that may arise about the squad’s power in disputes swiftly to bed.


Offering comprehensive patent intelligence and a rock-solid filing capacity, BRANN astutely manoeuvres its pan-disciplinary following through the IP minefield. Peers praise the squad for its “meticulous and thorough understanding of technology” and its strategic advice. Annika Kilander is a stand-out; she is a mechanical engineering authority, is “incredibly experienced in patent work and takes a deeply pragmatic approach”. The European patent attorney boasts significant time spent in-house and in private practice, and applies this towards realising the optimum commercial value of innovation and developing a clear path to fully fledged patent portfolios.

Fenix Legal KB 

Sharing its clients’ innovate-or-die outlook and their desire to maximise returns from assets, Fenix Legal is a “highly professional, business-minded and flexible boutique that offers vital feedback on how to proceed, amend and develop so as to transform basic ideas into patentable material”. “The strong team of patent attorneys are adept in all technical disciplines and perform patent searches, filing, disputes and licensing quickly and at a very reasonable price.” The quality reflects CEO Maria Zamkova’s unrivalled expertise in IP and business matters. As one beneficiary of her advice effervesces: “She has the spirit of an entrepreneur” and is “an expert on European patents and international rights protection; she is simply the best patent attorney we have worked with”.

Groth & Co

It has been another great year for Sweden’s longest-serving IP outfit, Groth & Co. A roaring trade in patent work is driving pronounced financial growth, while the set’s “thorough technical reach” has been strengthened by the arrival of three new life sciences attorneys making the switch from a competitor. Its substantial offering allows it to excel where others might not; it exhibits a mastery over more esoteric innovation in the healthcare field and can also step in to relieve the burden on smaller in-house operations when resources are stretched. Long-term clients value the “effective, responsive and timely” attorneys’ contributions in both contentious and non-contentious instructions. “They’re competent, flexible and they listen to buyers’ needs.” Head of the patent department Mathias Loqvist is the key contact for interested parties.

Kransell & Wennborg AB

Kransell & Wennborg’s raison d’etre is patent prosecution and it offers consumer-focused, business-minded and personal service in drafting, strategy and litigation support. The hiring of two new European patent attorneys continues its steady growth. Among its technically masterful line-up, peers commend Johan Wennborg and Anders Wiren as “talented and intelligent attorneys”. With extensive experience prosecuting patents before the European and the Swedish patent offices, the former patent examiner Wennborg is an “immense assistant” to rights holders and boasts a rock-solid reputation on the Swedish market. “With a broad grasp on a range of technologies, he chooses the perfect angle from which to approach rights protection. He also takes an active role in complex pan-European work where his high-quality advice and remarkable language skills have been incredibly valuable. Wiren plays a crucial role in clients’ development; he is a splendid engineer, a practical negotiator and an expert in patent law.”

Mannheimer Swartling

Mannheimer Swartling is “one of Sweden’s leading names in the IP sphere – typically handling around one-tenth of all the patent clashes before the courts, yet best known for its transactional abilities”. Over the last 12 months, titans including Leo Pharma and Novartis have counted on its litigation muscle to coach them through heated disputes, while Volvo and Google have respectively requested its supervision in formalising a joint venture and the acquisition of a competitor. Commended for his abilities in both arenas, “Per Josefson is a highly experienced IP litigator”. Oscar Björkman Possne shares his fellow attorney’s dual focus, expertly assisting on the Novartis instruction and advising on the IP aspects of the Google deal. In recent years the firm has eschewed lateral hires to focus on organic growth and nowhere is this more evident than in Possne’s promotion to partner.

Noréns Patentbyrå AB

Noréns Patentbyrå’s capable line-up makes a strong showing on the national scene – its software and high-tech specialists are stand-outs within an impressive all-around team. Positioning itself to take advantage of the flourishing start-up scene in the region, it is a natural choice for smaller domestic players and hires itself out as a cost-effective alternative to permanent in-house staff. Experience in contentious encounters and strong ties to Sweden’s best attorneys at law ensure that its clients have little to fear when tensions arise. With his IT background, managing partner and European patent attorney Johan Örtenblad knows exactly how to help businesses thrive.

Roschier, Attorneys Ltd

“A quality offering in Sweden’s transactional IP space for more than a decade”, Roschier has transplanted its Finnish office’s reputation for contentious IP work onto the local market. Loyal follower Nokia opts to use the firm across both jurisdictions in its global patent war with Apple, while major operations in the energy, pharmaceutical and medical device fields seek out its counsel too. Taking point in both battles and negotiations, European Patent Lawyers Association blog editor Erik Ficks is “a flexible attorney with far-reaching expertise in patent litigation”. His consumer focus and rapid response times are a boon for his devotees.

Sandart & Partners Advokatbyrå KB

“With a mountain of experience in instructions across every technical discipline, Sandart & Partners is a go-to in a clash. Well deserving of its place in the gold tier, clients can feel confident that this patent-centric IP boutique can handle any dispute”, assures one competitor. “We’ve faced its incredible team in many a heated encounter, and it’s always a fantastic experience.” For 35 years, the renowned Dag Sandart has been at the heart of the Swedish IP scene. Singled out for his prowess in the courtroom, “Sandart always has a few tricks up his sleeve” to ensure his client comes away victorious. He is a top name for striking IP covenants too; his regulatory know-how and transactional savvy bring harmony to complex licensing and contractual matters for his life sciences following. “The top contender in high-stakes patent litigation, Peter Sande is a fabulous and knowledgeable attorney. If we have a conflict, it’s Peter we go to”, one illustrious peer enthuses.

Setterwalls Advokatbyrå AB

An “impressive, fast-growing” full-service law firm making a splash on the patent scene, Setterwalls flexes its litigation muscles in a huge percentage of all clashes before the IP courts. “It has been the dominant representative of generic pharmaceutical players for a long time, earning its high ranking.” Beyond the life sciences, the set is an established force in heavy industry and consumer goods circles, and is frequently sought out for its counsel on the IP aspects of initial public offerings. “Heading its growth across the board, Per Lidman is a shrewd operator – accessible, straight-talking and knowledgeable” in both high-stakes altercations and in patent due diligence and contractual matters. His colleague Martin Levinsohn ascends to the silver tier this year; “a calm and collected attorney, he convincingly presents his cases to the court”. His subtle approach has been an essential pillar of battle strategies for Actavis, Sodastream and Sandoz. For the latter, he swiftly turned predator into prey, batting away an injunction brought by ViiV relating to its abacavir + lamivudine patent and challenging its validity in revocation proceedings. “A deeply experienced and highly skilled litigator, Lennart Arvidson is the practice’s number one and has been for nearly 30 years.” With a keen regulatory and IP mind, he continues to take an active role in high-profile conflicts for clients including heat-exchanger giant SWEP International.

Ström & Gulliksson AB

From its headquarters in Malmo, Ström & Gulliksson plays a vital role in the prosecution and enforcement strategies of its diverse client base. “A proficient outfit experiencing considerable growth”, it is a prime choice for instructions across the contentious/non-contentious divide and a favourite among pharmaceutical powerhouses for its technical support in litigation. For these players, dedicated, proactive and creative attorney Rikard Roos “quickly identifies and understands the relevant issues of any case; he plays an instrumental and inventive role in any high-stakes litigation team”. Electronics and computer technology savant Björn Andersson boasts an unrivalled breadth of talent; “vastly experienced in proceedings before the EPO”, the able prosecutor is valued for his non-contentious strategy and has also contributed his expertise to six separate IP litigations over the last 12 months. “With a good eye for detail and incredible technical knowledge, Björn adds value through his pragmatic and accessible style.” Telecoms, media and technology expert “Christian Arkelius stands out from the crowd. Detailed and hands-on, he is the best kind of patent attorney and gets to grips with every aspect of an innovation. Top of the list when it comes to knowledge of European and Asian patent processes, he is also able to write US-style applications – a rare gift for attorneys outside of the United States”.

Synch Advokat AB

Innovative and commercially oriented, Synch’s IP team has attracted a lot of new business in the last year, taking on both contentious and non-contentious patent instructions and providing access to the Swedish market for US-based investors via its office in Silicon Valley. Transactional endeavours are the firm’s bread and butter; it is a major negotiator of licensing agreements for the domestic high-tech scene. Start-ups particularly value the tailored offering and transparent pricing the side offers, knowing that they can pick and choose from a range of services. David Leffler stands out for his work in this sector. A former legal adviser to the Swedish Patent and Registrations Office, he is currently secretary of the Swedish chapter of the International Association for the Protection of Intellectual Property and has contributed his expertise in cross-border IP work to the International Comparative Legal Guide to Patents 2017. Co-founder Sara Sparring is an expert in striking bargains in the life sciences and pharmaceutical arenas. In the past 12 months, she has been busy advising on a range of licensing issues, providing sound oversight to domestic and multinational actors.

Valea AB 

“One of Sweden’s largest IP boutiques, Valea is in prime position to capitalise on the country’s booming domestic patent market.” Major life sciences and automotive actors count on its talents for securing rights protection as well as its prowess in opposition proceedings before the EPO. The United States and Asia are a strong source of growth too, with the extensive line-up handling significant inbound work from these jurisdictions. Supported by “highly valued, trustworthy attorneys and paralegals, Andrew Hammond acts as if he were a member of our in-house team”, expounds a major client. “Famous for his performance in oral proceedings, Hammond is technically skilled and very experienced. His thorough knowledge of case law” is an asset in opposition, invalidity and infringement cases. He champions the rights of flooring titan Unilin; his defence of a patent owned by its recent acquisition, Pergo, is a major success story for the outfit based on the potential loss in licensing income had his arguments not proved so convincing.


“Holding the majority stake in the patent litigation market”, Vinge is a force to be reckoned with in the courtroom, championing the interests of major players in the healthcare, telecoms and high-tech arenas. “Probably the best patent litigator in Sweden, Håkan Borgenhäll has all the prestige that comes with the title and deserves his place in the gold tier. A highly skilled professional, you definitely want him on your side rather than across the aisle.” He is an essential ally in battles for high-profile rights holders including Eli Lilly, for which he has led on the Swedish arm of a global infringement battle against Actavis. He has also advised the Swedish government on issues surrounding the Unified Patent Court and is an expert on the committee responsible for drafting the new Swedish Patent Act. Working alongside Borgenhäll for Eli Lilly as well as sealing a number of IP deals for other actors, Ulf Dahlgren possesses a vast skill set. As one admirer confesses: “We regularly consult Ulf regarding possible infringement, knowing that he provides sound advice and action plans; we also ask his respected opinion on our applications prior to filing.” The IAM Patent 1000 luminary has earned his status through “hands-on, business-oriented and cost-effective legal advice”.


More than doubling its workforce in recent years, Scandinavian heavyweight Zacco handles patent prosecution and enforcement work for market leaders. The group’s unique focus on digitalisation and information technology reflects both its attorneys’ technical expertise and the office’s internal processes. Software, pharmaceuticals and automotive actors are increasingly drawn to the firm for its IP strategy and skill in opposition. Sought after as co-counsel in invalidity and infringement proceedings, it has represented behemoths including Eli Lilly against Actavis; for Bayer Healthcare, it has taken a battle against the Swedish Patent Office to the High Court, successfully correcting the duration of several supplementary protection certificates. A crucial player in this case, Michael Byström is an experienced prosecutor of pharmaceutical and biochemical patents. His business-oriented approach has been key to expanding a broad client roster. From offices across Sweden Jörgen Linde and Peter Ekwall carve up the domestic market, handling east and west respectively. Linde is a life sciences sage, skilled in due diligence, strategy and opposition proceedings, while Ekwall provides his shrewd counsel across contentious and non-contentious instructions.
