Gowling WLG’s relatively fresh-faced Dubai IP practice has quickly gained recognition from peers and clientele alike. The team of 12 experts is well-attuned to working with both locals and multinationals. Aside from cultural acuity, practitioners possess language skills in English, Arabic, Mandarin, French and Cantonese. As such, they are well-positioned to offer a wide array of services that cover not only the UAE, but also the wider region. In complex matters, the local set can also leverage access to the network of more than 200 experts based across three continents. At the helm of the practice stands the seasoned Jon Parker, a valuable ally especially in prosecution, transaction and infringement matters. Having joined the team in 2021, Tamara El-Shibib has significantly boosted the outfit’s patent capabilities. An esteemed technology transfer expert with a flair for IP commercialisation, she gained significant experience working for the Qatar Foundation, and assisting start-ups and government agencies in patent prosecution and commercialisation. Under her guidance, the practice conducted a series of webinars on the topic of tech transfer in the region.

Canada’s largest law firm, and a global giant, Gowling WLG boasts a formidable roster of patent practitioners in London, with top-flight expertise and market-wide recognition. “Huw Evans is one of the UK’s best known and most experienced IP litigators. He is an excellent solicitor and heads up the patent litigation team at Gowlings WLG. At a recent patent entitlement dispute in the High Court, he provided excellent commercial and strategic advice. He can also offer innovative commercial solutions, without having to resort to litigation.” Telecommunications IP expert Alexandra Brodie co-chairs the tech sector group and is a renowned authority on SEP and FRAND litigation. She has been among the United Kingdom’s leading litigators in the space for over 25 years and can confidently and expertly navigate the most complex, cross-jurisdictional suits. She was instructed by InterDigital in its multi-year battle with Lenovo. Success has been secured for InterDigital in three rulings in early 2023. “Gordon Harris is a well-respected leader in the patent litigation space. He transformed the Gowling WLG practice into one of the best in Europe.” “Seiko Hidaka’s knowledge of patent law is unparalleled. She is also a fluent Japanese speaker, an obvious benefit to clients from Japan.” Other key names to know on the contentious side are Paul Inman and Luke Kempton. Inman has a background in molecular biology and biochemistry and more than 25 years’ experience in the patent profession. He has an impressive track record of success for pharmaceutical companies and is both technically savvy and a keen litigation strategist. Biotech and life sciences expert Kempton is a deft hand with contentious and non-contentious patent matters. He has a PhD in biochemistry and also knows the commercial landscape of the sector very well, allowing him to tactically guide his patrons through enforcement, and potential enforcement, scenarios with confidence and dexterity. On the non-contentious side, the outfit boasts one of the country’s best-known authorities on patent licensing in Patrick Duxbury. Duxbury heads the life sciences group and trained as a microbiologist and geneticist before becoming a solicitor. He balances this deep technical expertise with equal dexterity in commercial and business issues, carefully steering the trickiest of transactions in favour of his clientele. Adding depth to the outfit’s listing this year is trade secrets working group co-leader Matt Hervey. Hervey is a recognised authority on AI and all SEP/FRAND issues. He regularly integrates his AI and trade secrets practices, helping companies to protect their most valuable knowledge in this sector. Another newcomer to the IAM Patent 1000 this year is Jenny Davies, a life science specialist with contentious and non-contentious experience. She has supported Inman on litigation for GSK, alongside work on a range of other matters.

A respected presence in China since 2008, Gowling WLG was the first foreign firm to file a patent application in the country. With both patent attorneys and lawyers stationed in three offices across the country, it is a persuasive one-stop shop for rights holders of all sizes from all corners of the globe. With his 17-plus years in mainland China, Elliot Papageorgiou meets and exceeds patrons’ demands at the trade secret and IP disputes frontier. “Elliot is strategic, prompt, responsive and, above all, his advice is always relevant, practical and business-centric. His team provides excellent IP services in what could otherwise be a challenging jurisdiction.” Also receiving high praise is Beijing-based managing director Jian Xu. “Jian is not only always very responsive but he succeeds in giving us and our clients a good understanding of the – for Europeans sometimes unusual – specifics of Chinese IP law.” A biochemist by trade, he is the main draw for Gowling’s China prosecution instructions.

As one client comments: “In our opinion, Gowling is second to none in the world. After using various other firms, it has proven itself to be the best. The team is diligent, focused and knowledgeable, especially when navigating challenging issues in new fields.” The outfit operates across the contentious/non-contentious divide, handling every mandate that crosses its desk with ease. On the prosecution side, 12 of its esteemed practitioners have been ranked and have no shortage of work to keep them busy. On behalf of ModiFace and L’Oréal, James Longwell has been prosecuting applications worldwide related to augmented reality, such as AI-based image analysis; Brian Lee continues to work with General Fusion on the drafting and filing of over 60 patent matters; Medicago has entrusted its global patent portfolio to Sonia Ziesche, who is managing over 500 patents – including its covid-19 vaccine; Omar Nassif oversees Precision Cancer Technologies patent estate, essentially acting as its in-house counsel; and Susan Tandan has been assisting both Edible Impressions and Canna Clear with their applications. Also on deck, Grant Tisdall is a go-to for technology companies looking to expand their portfolios. He creates bespoke innovation strategies that best codify intangible assets in accordance with business objectives. In the life sciences, Brian Kingwell and Jennifer Wilkie are the names to note. Kingwell delivers astute portfolio counselling to rights holders in the molecular biology, biochemistry, and medical devices space, while Wilkie has been a trusted adviser to leading companies such as Novartis, Merck and Janssen. Joining the Canadian team in September 2022, David Aylen spent several years as managing partner of the firm’s Eurasian division. His global outlook guarantees that patrons are well protected. “Daniel Polonenko’s extensive knowledge and experience results in strategic IP strategy, protection and preventative planning, which then results in significant value for clients’ portfolios. He has a distinct business-focused approach that is invaluable in maximising value and charting the right path for IP monetisation, with preventative protection always being a priority.” “You can count on Selena Kim to provide excellent work, even at very short notice. She is dependable, pragmatic and a partner worthy of high recommendation.” “Roch Ripley tailors his service to his clients’ demands by combining his legal expertise with his degree in electrical engineering. He is a strong, strategic partner, who helps to revamp approaches to filing patents.” When things turn contentious, the outfit also has a robust line-up of lawyers on hand to tackle any issue. In the life sciences arena, Jay Zakaïb is acting on behalf of Takeda Pharmaceuticals, handling an infringement related to the drug Dexilant, which is used to treat stomach acid; and John Norman is defending Biogen against two generic companies over a drug that helps patients with multiple sclerosis to walk. After three-and-a-half years, Christopher Van Barr and Michael Crichton successfully saw through a decision for Google that concluded in a three-week patent trial where 28 witnesses presented evidence. Crichton also teamed up with Nelson Godfrey to defend BC Hydro and Power Authority in a patent infringement case involving ways of detecting electricity theft. And Ronald Dimock and Laurent Massam recently successfully represented JemPak Corporation in an infringement involving two detergent patents. Rounding off the line-up, Anita Nador has been counselling Providence Therapeutic Holdings, a clinical stage biotechnology company, on the negotiation of two agreements that would allow Everest Medicines to license rights to its mRNA covid-19 vaccine to applicants in Asia.
