The Danish IP scene is thriving; firms are pulling out all the stops to keep up with the increasing amount of work coming their way, as various trends in disruptive innovation shift the market emphasis onto new technologies and computer-implemented inventions. Other than the rise in the number of biosimilar cases, the market for litigation has not changed a great deal – although apprehension remains regarding the future of the Unified Patent Court (UPC). Practitioners fear that the slow trickle of pharmaceutical players taking their work elsewhere in the continent might become a deluge following UPC implementation. However, in the short to medium term, the outlook is good.

Accura Advokatpartnerselskab

Transactional guru to a multitude of high-profile life sciences operations, Accura Advokatpartnerselskab boasts a flair for negotiation and a passion for commercial law work. A fresh face at the helm of the IP team, Morten Bruus adds his striking contentious nous to the team’s already substantial skill set. A trusted ally to both domestic and international partners in the pharmaceutical and high-tech arenas, he is charged with re-stringing the practice’s bow – a task to which he has taken with vigour, priming the office to handle whatever clients send its way.


Followers of Scandinavian IP troupe AWA perceive its excellence to be rooted in “experienced, well-prepared and client-oriented attorneys”. One client enthuses: “We are consistently met with professionalism, straightforward protection proposals and strong performance in opposition and infringement proceedings.” A strategic powerhouse, the firm appeals to the flourishing start-up scene, which appreciates its strong digital focus and growing emphasis on the Asian market. Life sciences maven Sidsel Hauge tops the increasingly diverse technical cast. An incredibly experienced prosecutor, she is also an instrumental operative in contentious work across myriad industries. Shoulder-to-shoulder with Hauge in tackling the surge of construction cases is Eva Carlsson, who “quickly understands clients’ businesses and builds robust protection strategies to match”. A polyglottal renaissance woman who has been with the set for 25 years, she is “devoted to securing IP rights nationally and regionally without restriction”.


A first choice for generic drug manufacturers, Bech-Bruun is the big competitor in pharmaceutical patent litigation. As one client enthuses: “It deserves its gold ranking and is rapidly closing the gap at the top of the market.” Boasting a “significant life sciences patent practice” within its Copenhagen office and a mechanically focused Aarhus offering rated second to none among Danish IP firms, the group provides a steady pair of hands in transactional affairs. It has continued to expand its roster of largely international clients, which appreciate its “outstanding expertise and commercial mind-set”. This drive and reputation was a potent draw for ex-Horten attorney at law Martin Draebye Gantzhorn, who joined the line-up last year, adding his patent prowess to the mosaic. The centrepiece is experienced litigator and transactional sage Klaus Ewald Madsen. He channels his proficiency in patent law for life sciences and technology giants; his aggressive defence of Teva in infringement proceedings brought by AstraZeneca relating to the quetiapine patent won the former the largest damages award ever secured in Danish patent proceedings. Whether assisting Madsen or on his own, Johnny Peterson is in demand for his sound counsel and strategic approach. Catering to his domestic following, Dan Bjerg Geary delivers an outstanding service: “His success reflects his in-depth knowledge – both practical and theoretical. He is one of the top IP lawyers in Denmark.” The motor behind the Aarhus office’s ascendancy, Geary received a well-earned promotion to partner this year for his efforts.

Budde Schou A/S

“Strongly recommended as a technical consultant by attorneys-at-law”, Budde Schou is a first-class patent attorney troupe. Channelling over a century of hard graft in IP matters, the set is “an extremely able, high-quality performer” in both contentious and non-contentious work, prosecuting and enforcing IP rights nationally and at the European level. Its shrewd business acumen and knack for securing and defending supplementary protection certificates wins a devoted following – and renowned life sciences specialist Steen Wadskov-Hansen caters to their every want. “One of the most original strategic thinkers in his field and a go-to for pharmaceutical clashes, Steen is intelligent, analytical and understanding of litigators’ needs. He is a joy to work alongside.” With his 40 years of experience handling mechanical instructions, Leif Rørbøl is a court-appointed expert in the Maritime and Commercial Court. Simply put, his contribution to the firm is “irreplaceable”.

Chas Hude A/S

Drawing on “an extensive international network of foreign associates, personnel competent in relevant technical arenas and a streamlined digital infrastructure”, Chas Hude is among the best patent attorney offices for life sciences and biotechnology operations. “It has repeatedly proven its mettle in securing rights protection, and has, on more than one occasion, demonstrated an ability to turn around a final rejection at the patent office.” High esteem inevitably prompts more instructions, and the capable band has broadened its strategic counselling and transactional offering in response, delivering a cradle-to-grave service. Biotech savant Marianne Johansen stands out for her “proactive approach and strong interpersonal skills”. As well as being a skilled prosecutor, she “knows how to run a business, too”. Johansen works with her predominantly national client base to realise commercial value from their patent portfolios. Qualified to act before both the European Patent Office and the US Patent and Trademark Office, Jesper Mark Wenzel has seen more than his fair share of complex instructions; he is a calming voice in oppositions and appeals.

COPA Copenhagen Patents

COPA is among the best patent attorney firms in Denmark: “Modern and client focused, it is extremely competent in patent prosecution and a preferred co-counsel in contentious matters.” Litigators appreciate its high-quality service delivered at reasonable rates. “With a strong track record in the biotechnology and medical device fields and an up-and-coming detachment of flexible and pragmatic individuals, the group is a pleasure to work with and clearly deserving of its tier-one position in the market.” Those seeking the firm’s technical assistance need look no further than founder Mikkel Bender, a life sciences authority with extensive experience: “He’s very able, delivers quality results and cultivates a wonderful atmosphere whenever he’s involved in a case.” Steven Richard Kitchen is “a valued member of any team”. The “highly intelligent” prosecutor homes in on the important aspects of any case; his steadfast enforcement and strategy work “has earned him enduring respect in the mechanical engineering community”. Highlighted for his 30 years in patent prosecution, Peter Kim Jensen is one of the big names in Danish intellectual property; he sits as a technical judge in the Maritime and Commercial Court.

Gorrissen Federspiel

Peers spontaneously cite Gorrissen Federspiel’s regulatory prowess and the “excellent lawyers” behind its robust life sciences IP practice. “It’s a strong player in the patent scene and a discerning choice for pharmaceuticals.” Capitalising on a boom in mergers and acquisitions over the last year, the set has thrown its impressive faculties into negotiations over licensing agreements and patent transactions for Europe’s largest operations. It has skilfully navigated due diligence instructions for many clients and is frequently summoned for its services in the courtroom when disputes arise. Charged with responding to any eventuality, Jacob Ørndrup is a regulatory sage and “brilliant litigator” who specialises in medical device and chemical disputes. Admitted to the Supreme Court, he is a dab hand in infringement proceedings and fights every battle to the bitter end. Operating out of Aarhus, mechanical specialist Kenneth Kvistgaard-Aaholm is a “clever guy with excellent legal, strategic and technical skills”; he is an asset both in the courtroom and at the negotiating table.

Guardian IP Consulting I/S

Enterprising prosecution shop Guardian IP Consulting is doing extremely well: “Already boasting a line-up of European patent attorneys with significant industry experience, it has continued to bring seasoned specialists on board and is one of the most qualified teams in Denmark; the work it does is excellent.” The set’s diverse client roster is “a strong indicator of the quality of its output, and its excellent reputation”. Peers point to “excellent IP manager” Holm Schwarze as “a leading attorney among many strong practitioners” and a trustworthy prodigy in the physics-related fields; he accompanies his clients every step of the way to rights protection. Electronics specialist Henrik Bagger Olsen tailors his offering to clients of any size. He turns his keen eye for patentable material toward realising maximum value from companies’ innovations. Life sciences maestro Lars Pallisgaard Olsen is a cool head in a crisis and is sought after as litigation co-counsel for his far-reaching technical expertise.

Horten Law Firm

If Copenhagen’s Horten is suffering following the loss of one of its best litigators to a competitor, it is not showing it. The gold-tier outfit remains a trusted partner to generic drug manufacturers, handling a significant volume of contentious and non-contentious patent instructions on their behalf. “Certainly up there with the best litigators in Denmark”, Anders Valentin leads a powerful IP team. He is a “clever lawyer” whose courtroom performance and transactional proficiency is essential to multinationals including Synthon and Chemo: “Friendly, experienced and client focused, he understands complex issues and responds with creative solutions.” Still active and expertly assisting Valentin in many of his endeavours, Ole Damsbo is an icon in Danish intellectual property. His impressive résumé includes over 45 years spent honing his craft and positions in the country’s top IP outfits.


“A go-to for the chemical industry”, HØIBERG delivers internationally-oriented patent strategy and portfolio management to both domestic R&D institutions and major multinationals. The team of European patent attorneys is directed by former doctor and medical researcher Susanne Høiberg. “Best known for her finely honed abilities in the life sciences arena”, she exhibits a keen commercial aptitude and strategic mind that is a blessing to her devotees. Both Høiberg and fellow partner Claus Elmeros are skilled contentious operators and each also sits as a technical judge at Denmark’s Maritime and Commercial Court. Head of litigation and oppositions, Elmeros is also a prolific prosecutor and a specialist in mechanical engineering.

Inspicos P/S

These days, clients and litigators want a personal relationship with their technical specialist; for this, Inspicos’s “stable core of hand-picked patent attorneys” are second to none: “A favourite for prosecution and opposition work, it is a first choice in Denmark, renowned for its quality and attention to detail.” According to one peer: “It really comes down to the individuals, and Jacob Pade Federiksen is extremely able.” A “flagbearer for Danish mechanics”, he is excellent in high-tech briefs as well. Clients appreciate the “high-quality service and significant experience” he offers – particularly in opposition proceedings, which are his metiér. Federiksen shares these high standards with co-founder and biotech aficionado Peter Kofoed. Having spent time as an in-house counsel, Kofoed appreciates the needs of industrial players and helps them to realise their desired outcomes in prosecution, litigation and transactional matters. Chemical maven Ulla Klinge is a contentious genius and is in demand among domestics and multinationals; she sits as an expert judge at the Maritime and Commercial Court.

Kromann Reumert

“Recently strengthened by the appointment of a new partner, Kromann Reumert boasts excellent professionals, yet remains something of a one-man army – its success largely attributed to the splendid work of Nicolai Lindgreen. Deserving of its place in the gold tier, the firm is one of the main competitors in Danish intellectual property – with extensive experience in patent litigation and an ability to tackle the most complex instructions.” Of Lindgreen, peers confess: “He’s the kind of guy you wish was on your team. One of the best patent litigators in the country; he’s a good lawyer, a really nice guy and an excellent performer in court.”


Boutique litigation outfit Lundgrens “leaves no stone unturned” in complex life science instructions. A number of lateral hires have enabled “a much wider footprint and more visibility than ever before”, while its devotion to quality ensures that growth is organic and standards are never compromised. At the heart of a “diligent, responsive and well prepared group”, Jakob Krag Nielsen and Rasmus Vang are “incredible litigators and masterful tacticians from beginning to end”. Nielsen excels in the life sciences field, “transforming his far-reaching experience into actionable business advice”. Working alongside Nielsen in pharmaceuticals disputes, Vang is an irresistible force in a courtroom clash. He complements his offering with a strong technology focus and wins impressive victories for clients in heavy industry as well.

Plesner Advokatpartnerselskab

One of the best known firms in Denmark, gold-tier unit Plesner is one of a kind: the singular representative of pharmaceutical originators on the Danish landscape, it possesses a mastery over the major challenges facing these players. Mikkel Vittrup and Sture Rygaard run the “broad” IP and patent practice, promoting mechanical endeavours alongside those in life sciences. Clients value the “fruitful cooperation” that Vittrup’s involvement inevitably prompts; he specialises in securing preliminary injunctions against alleged infringers of medical device patents and comes highly recommended for his skill in negotiating licensing agreements. A biotech expert, Rygaard shares Vittrup’s talents for litigation and possesses a keen strategic mind. “A star performer in court, Jeppe Brinck Jensen has really strengthened the offering. A rare combination of theoretical intelligence and business acumen, he is an extremely skilled life sciences litigator who offers outstanding advice on patent infringement and supplementary protection certificates. Approachable, efficient and concise, he is a pleasure to work with.” “The grandfather of Danish patent law”, Peter-Ulrik Plesner continues to be a powerful voice in infringement proceedings. His arguments have recently been instrumental in a major victory for AstraZeneca. Best known for his skill in trademark litigation, Kasper Frahm is also an exceptional patent litigator; he ably assisted Plesner in arguing key procedural questions in the AstraZeneca case.

Plougmann Vingtoft 

Plougmann Vingtoft’s “strong position in the Danish legal market” and the loyalty of high-profile multinationals bear testament to its “experienced, intelligent attorneys” and their remarkable faculty for prosecution. Its IP strategists deliver “tailored and up-to-date market advice” to meet any requirement clients may have. Both experts in the mechanical field, Peter Sørensen and Michael Friis Sørensen come highly recommended for their gifts at the European Patent Office. Peter Sørensen’s “insight into the market and knowledge of his field” ensures that he works in harmony with in-house technical teams, while Michael Friis Sørensen is a former research engineer who guarantees his clients a sympathetic ear and a robust strategy to achieve their goals. Katja Sørensen is a food and life sciences specialist, active on both sides of the contentious divide. She ably assisted the set’s contentious mastermind Kim Wagner in his sally on behalf of Scandinavian dairy giant Arla Foods. “Kim Wagner stands out in litigation, demonstrating his rounded knowledge of patent law. His experience and understanding ensures his performance in oral proceedings carries the maximum possible weight.”


Scandinavian prosecution heavyweight Zacco is “efficient, cost effective and professional”. With offices across Europe and a robust quality management system, it “easily achieves outcomes smaller outfits would struggle to replicate”. Its line-up of excellent individuals continues to grow and Michael Schandorf Sorensen stands out among them: “A leader in his field, he understands the science behind innovation, and uses this to uncover the best routes to rights protection, adding value through his humble, team-oriented approach.” Managing and prosecuting the European patent portfolios of high-value multinationals, electronics specialist Camilla Rendal Nielsen is also adroit in opposition proceedings and patent due diligence. Pernille Thorsboe and Ejvind Christiansen are a formidable duo in contentious work. Thorsboe is “incredibly knowledgeable” and an asset in complex pharmaceutical cases, particularly those relating to supplementary protection certificates, while former vice president of the International Association for the Protection of Intellectual Property Christiansen is “without doubt, the most experienced patent attorney in Danish IP litigation”. With expertise built up over 30 years in practice, Thomas Sundien is a renowned prosecutor; he employs his skills as a technical judge at the Copenhagen Commercial and Maritime Court.

Other recommended experts

Foreign associates heap praise on Annelise Holme, a versatile practitioner dexterous in drafting, oppositions and infringement proceedings. From family business Holme Patent, the “incredibly talented” microbiology expert delivers a “cost-effective” service before the EPO and in the Danish courts. “Peter Indahl is one of the best patent attorneys out there. A specialist in electronic and mechanical engineering, he’s a reliable professional who is extremely easy to work with.” A former resident of Awapatent, he recently struck out on his own, launching self-titled operation Indahl. Nicka Kirstejn “has an in-depth legal and technical knowledge”; experienced in biotech and medical device instructions, his input in these cases “is extremely valuable and maintains a fine balance between cost and quality”. He recently left COPA to set up new outfit Aera. Joining Kirstejn at Aera, biotech specialist Per Larsen is an outstanding attorney who genuinely relishes the task of obtaining rights protection for clients. A clear and direct communicator, he really takes time to consider an instruction, ensuring that his recommendations are useful and easy to follow. Also making the switch from COPA to Aera, Anders Sandgaard is a seasoned patent prosecutor and an expert in computer-related inventions. The savvy IP strategist is in demand among high-tech concerns, for which his technical experience is a potent draw. Nordic Patent Service managing partner Gerard van Walstijn is an IP master whose far-reaching expertise spans an array of technical disciplines. He serves as a guide to domestic and multinational entities, piloting them through prosecution, opposition and enforcement proceedings.
