Ilya Kalnish's Profile

Partner at BCF LLP, Ilya Kalnish supports large international corporations and smaller start-ups and scale-ups in developing complex IP strategies. He specialises in AI, IT and mechanics. Mr Kalnish is particularly effective at obtaining watertight legal protection for inventions in multiple countries around the world, while optimising the cost-benefits ratio associated with such procedures. With a focus on software inventions, he has mastered reconciling legal regime differences between Europe and North America, especially when it comes to protecting AI-related inventions.

Prior to joining BCF, he held key IP management positions in large national and multinational companies, where he gained valuable insights into how legal departments operate and the pressures that in-house counsel faces day to day. Mr Kalnish has participated in several ownership transitions, mergers and acquisitions (both as a target and a purchaser), and in numerous IP strategy realignment exercises. During his in-house days, he became proficient in supporting top executives in making IP strategy-related decisions.

Since migrating to private practice, he has mastered rendering business-focused advice to his clients, while keeping an eye on the budget and expenses. His practice focuses on the end-to-end patent procurement process, from invention identification to drafting and prosecution. He also advises his clients on global IP management, both in terms of risk management associated with new product introduction processes and due diligence in the context of M&A transactions. His approach is strongly grounded in his belief that IP protection is first and foremost meant to support, promote and spearhead business strategy.

In 2017, 2018 and 2019, Mr Kalnish received the ILO Client Choice Award, a prestigious award that honours the best professionals in the legal sector, as selected by clients. He has also been ranked among the world’s leading IP practitioners in IAM 1000 since 2020. He dedicates a significant amount of time to training newcomers into the profession through his extensive involvement with the Intellectual Property Institute of Canada’s patent agent exam preparation courses. He speaks English, Russian and Bulgarian fluently.
