The relative youth of the Ukrainian patent market can sometimes prove frustrating for practitioners, as progress can be slow. However, it also has its advantages, as the country’s thought leaders are effectively free to act as the architects of their own ever-evolving IP system. It is hoped that the advent of the new High IP Court will help to cultivate an IP scene that finally reflects the size of Ukraine and the ambition and ingenuity of its inventors.



AEQUO is a renowned name across virtually all areas of the law, but its IP practice is one of the jewels in its crown: recent patent highlights include staunch representation of Dr Reddy’s in a precedential biosimilars case before the Superior Commercial Court. The firm can cater to clients’ every wish and need, since its patent and trademark prosecution, litigation and transactional capabilities are matched by strong commercial and competition practices. The leading light is Oleksandr Mamunya – a safe pair of hands for patent litigation, prosecution, and IP due diligence. A key point of contact for matters before Ukrpatent, Mamunya is an influential figure whose input has helped to shape the drafting and amendment of the country’s IP legislation.

Baker McKenzie

Thanks to the wider firm’s unparalleled geographical reach, the Kyiv office of international powerhouse Baker McKenzie is ideally positioned to service both domestic and global clients seeking to protect and defend their inventions in the jurisdiction. It recently played a crucial role in a high-stakes patent invalidity case on behalf of a multinational pharmaceutical corporation; and continues to manage extensive portfolios in sectors as varied as ICT solutions and nuclear energy. Its crack squad of practitioners is captained by Ruslan Drobyazko, a true IP doyen whose transactional insight lends an extra dimension to his refined portfolio management.

Doubinsky & Osharova

“Doubinsky & Osharova has been on the market for as long as the market has existed. It files a lot of patents and is a base for good lawyers and good litigators.” It is difficult to dispute the claim that the firm is the jurisdiction’s premier patent boutique: clients include international conglomerates as well as major local outfits in fields such as tobacco, pharmaceuticals and food. The twin figureheads are Michael Doubinsky and Irina Osharova, admired as veritable godparents of patent strategy in Ukraine. Doubinsky juggles his duties as managing partner with thriving practices not only in patent prosecution and disputes, but also in commercial and corporate law; while Osharova is a pioneer who was among the first 10 patent attorneys to qualify in the country.

Gorodissky & Partners Ukraine 

The Ukraine office of Gorodissky & Partners has been transformed over the last year, following the arrival of dynamic new patent head Maksym Bocharov. Companies of all stripes have come to rely on him for his astute advice on optimal protection for innovations and bulletproof drafting skills. Pharmaceuticals are a forte, but he is equally well versed in fields as varied as mechanical engineering and software.


Through a potent combination of technical expertise and legal know-how, boutique IPStyle provides an end-to-end patent offering, including filing applications both nationally and through the Eurasian Patent Organisation. Its bespoke approach has always been a USP, and more recently it has carved out a niche offering consultation services relating to the protection of patent rights in online marketplaces. A patent attorney and attorney at law, managing partner Mariya Ortynska regularly puts both qualifications to good use, filing patent applications across a range of technologies and racking up favourable results in litigation and out-of-court dispute resolution. Her right-hand woman is Iryna Ortynska – under her watch, the firm has successfully secured more than 1,000 patents over the last decade, largely in the fields of telecommunications and software.

Mikhailyuk Sorokolat & Partners

Ukraine’s national patent system was established in 1992 and alongside it Mikhailyuk Sorokolat & Partners – a firm which today houses more than 200 IP professionals in offices throughout Ukraine, Russia, Belarus, Georgia, Kazakhstan, Moldova and Uzbekistan. “Its attorneys are very experienced and we receive detailed responses in a very short time for all our queries. They file very quickly and produce quality work.” Firm CEO Valentin Mikhailyuk was the very first patent and trademark attorney registered in Ukraine and helped to mastermind the country’s modern IP system. He now spends his days conducting court examinations and advising on patent and trademark infringement and licensing. While the firm is a veteran of the Ukrainian patent scene, it prides itself on staying ahead of the curve: for example, managing partner Vadim Mikhailyuk was a driving force behind the development of an online patent portfolio management tool that both the firm and its clients use to monitor documents and correspondence.

Pakharenko & Partners

Hailed for its broad prosecution and litigation capabilities, as well as a stellar reputation both within the jurisdiction and further afield, full-service outfit Pakharenko & Partners ascends to the gold tier of the rankings this year. “They’re very good in their market and I’ve been very happy with them in the past, which is why I keep coming back to them,” reports one satisfied customer. “They know the laws well, including regulatory matters and IP law in general. They are responsive and are as creative as you can be in the Ukrainian market.” Under the command of managing partner Antonina Pakharenko-Anderson, it has been securing vast numbers of patents for multinational pharmaceutical and engineering players, and putting in persuasive performances in infringement disputes for clients of a similar calibre. Meanwhile, it has still found the time to develop a specialism in plant varieties – an area of patent law that is still in its infancy in Ukraine. The deep bench of talent at the firm includes Alexander Pakharenko, a patent attorney and attorney-at-law with an impressive affinity for patentability and licensing issues.


Luxembourg-based PETOŠEVIĆ has a sprawling network of 16 offices across Eastern Europe and the Kyiv outpost is key among them. With Dina Petošević at the helm since it was set up ten years ago, it safeguards the patent portfolios of top-flight US and European corporations and is also a frequent fixture in contentious proceedings before Ukrpatent. As regional manager for the Russian-speaking region, Petošević coordinates patent enforcement not only throughout those countries in which the firm has its own offices, but also in those in which it operates through affiliates.

Other recommended experts

Daniel Benatov of Dr Emil Benatov & Partners maintains strong connections with the firm’s Bulgaria office and, as a polyglot, can act as a bridge between the IP worlds of Western and Eastern Europe. Working out of T-Marka, Alexey Goriainov is the patent attorney to call for enforcement missions in the optoelectronics field. Natalya Lemeschuk is living proof that you don’t need to be based in Kyiv to provide top-drawer patent prosecution and transactional services: she runs the show at LEX Intels in Odessa. Full-service law firm Avellum has boosted in its patent capability with the lateral hire of Anton Polikarpov, a patent attorney and attorney at law with an enviable address book full of international contacts. A robust patent enforcement practice has made Julia Semeniy of Asters a familiar face at Ukrpatent; recent highlights include representation of global automotive giant Nissan.
