Making its way into the Hong Kong chapter this year on the back of glowing client feedback is the globally recognised CMS, which began to offer a full range of IP services in the special administrative regions of China at the beginning of 2020. “The firm displays a deep knowledge of the law and provides effective, business-oriented solutions to IP protection issues. Furthermore, the team is responsive to requests for assistance and unfailingly outlines in a clear manner all possible actions along with their advantages and disadvantages.” “What sets the firm apart is its reliable advice on a wide range of legal matters and its deep expertise.” Jonathan Chu leads the squad and works closely with Nick Beckett in the Beijing office to extend all-encompassing IP protection to clients across the Greater China region. “Jonathan is not just good at intellectual property; he also understands the importance of it in the context of a business or M&A transaction.” “Beyond legal advisers, Jonathan has become a trusted business associate who looks out for our best interests while managing our trademarks with clarity and professionalism. They offer truly holistic support to the company and take the time to understand developments and discuss the business as a whole.”

An unwavering dedication to clients characterises each outpost of CMS and the Polish contingent is no exception. “Our company and its internal processes are consistently changing, but CMS always evolves with us”, comments one satisfied customer. “It is our partner of choice through it all because of its flexibility and willingness to grow; and its data-driven decision-making processes are highly appreciated too.” Heading up the local and Central and Eastern Europe IP group is Tomasz Koryzma – “responsive, reliable, effective, practical and just the type of lawyer you want to work with. He does not just look to understand the technology and internal processes of a business, but also considers practical realities in a way that is most impressive”. Trademark attorney Maciej Olejnik brings an added dimension to the practice, with his thoughtful portfolio management and versatile prosecution toolkit.

“CMS is an excellent full-service law firm with a top-notch IP department. Its service is flexible and clients value its data-driven decision making.” Since the outfit’s high-profile merger three years ago, the trademark team has gone from strength to strength, with a steady flow of mandates across the trademark lifecycle landing in its inbox. This year alone it has been managing Legal & General’s global portfolio; meeting the total trademark needs of Nestlé and Sky; undertaking prosecution work for Microsoft; and tackling enforcement matters for eBay. IP head Sarah Wright is “responsive, pragmatic and commercial, with a keen eye for what each situation demands in terms of service delivery and cost. She is quick to grasp the key issues and able to cut to the chase. As a litigator, her advice is invaluable”. Global IP co-head Tom Scourfield is likewise a hit with patrons: “Tom provides strategic advice and draws on his extensive experience to provide commercial and practical guidance. He is responsive and always happy to problem solve.” Other bright lights in the CMS firmament include Kelly Saliger, Louise Gellman and David Parrish. Polished litigator Salliger has “thorough IP knowledge, a client-sensitive and straightforward approach, and an ability to coordinate complex cases perfectly”. Gellman is an adroit portfolio manager and Madrid System specialist who similarly turns heads: “Louise is very knowledgeable, but equally down to earth, making time for you even when she’s racing against the clock. She is an impressive lawyer and team manager who provides sound, commercially astute advice.” Parrish “dispenses advice that is commercial and practical, but guided by a solid technical understanding of the law”. Joel Vertes has worked on the team for 17 years and currently manages the portfolios of defence companies, gym chains and Oscar-winning actors. He conducts his substantial EUIPO practice from the firm’s Warsaw office in preparation for Brexit.

CMS Hungary does a stellar job coordinating cross-border work, serving as an efficient and effective regional trademark hub. Its “high-quality professionals” – many of whom are dedicated exclusively to intellectual property – are relied on by the likes of Microsoft and eBay, both of which have recently been assisted by Dóra Petrányi and Ágnes Sólyom. For Microsoft, the pair are providing enforcement and commercial IP advice; while eBay has enlisted them for representation in oppositions proceedings. Petrányi heads up the IP department; her insight on trademarks and domain names is complemented by granular high-technology, telecommunications and life sciences industry knowledge. Sólyom debuts in the WTR 1000 thanks to the full-bodied trademark support she provides across the contentious/non-contentious divide.

He recently advised Japan Tobacco International on trademark and copyright infringement matters in Russia and the European Union; represented Tesla Holding in an opposition in the Russian IP Court; acted for Otis Elevator Company in a dispute over the unauthorised use of its trademarks in Russia; and overseen trademark prosecution and strategy projects for Ecolab and Carrier Corporation. “Anton Bankovskiy and CMS Russia are a solid choice, thanks to their professionalism, strong experience and deep knowledge of trademark law in Russia.”

Breaking into the Spanish rankings for the first time this year is CMS Albiñana & Suárez de Lezo. Since the arrival of María González Gordon in 2019, the outfit has been making waves on the market, attracting global brands such as Victoria’s Secret and Bath & Body Works, as well as domestic heavyweights such as real estate groups GMP Property and CBRE España. The “exceptionally responsive and reliable” González Gordon recently assisted Virtual IP Assets – the world’s leading online casino and e-games provider – with its prosecution strategy, and US Polo with anti-counterfeiting efforts. “María’s professionalism shines through in every matter; as do her commercial focus and customer-centricity. She also has impressive legal knowledge, as well as a vibrant and engaging personality.”

The IP offering at commercial outfit CMS Carey & Allende is relatively new, but has quickly made a name for itself, particularly in enforcement circles. This is in large part thanks to department head Matias Somarriva, an authority in the area; as the Chilean partner to global anti-counterfeiting organisation React, he attracts a slew of instructions from an extensive network of contacts. No one-trick pony, Somarriva is also active in brand management and protection, on which he often teams up with Paz Marambio – a key contact for the firm’s most important clients, which appreciate his “high levels of professionalism and customer focus”.

With solicitors, trademark attorneys and trademark paralegals working hand in glove to tackle everything from registration to enforcement, CMS is a true one-stop shop for rights holders.

Accredited as an IP specialist by the Law Society of Scotland, he regularly appears in the Court of Session. Taking care of the transactional side is Carina Healy, who has a flair for the fine print of licensing, development and commercialisation agreements.
