A breath of fresh air on the Israeli IP scene, one-stop IP shop Cohn de Vries, Stadler & Co was established in December 2020 by three senior partners from another gold-tier firm ranked in this chapter. The experts’ vast and broad experience, as well as stellar reputation, has attracted hundreds of clients, from private innovators and start-ups to domestic and foreign corporations. Doctor of biology Ilan Cohn has his hands full with the patent portfolios of Can-Fite BioPharma, the Strauss Group and Solo Gelato. “Ilan’s holistic, creative and flexible approach to IP helps us to achieve and maximise our monetisation goals”, one referee says. Another founding partner David de Vries has a degree in mechanical engineering and over three decades of experience drafting, devising airtight strategies and dispensing incisive advice. “Quick and precise, David has an unparalleled understanding of engineering. He is very frank – if he feels there is something wrong with the patent, he will make it very clear.” He currently represents the Keter Group and Headovations; he has also been assisting Wheelchairs of Hope pro bono with its global patent registration. “Ilan and David work so well as a team.” Trilingual Svetlana Stadler shines in non-contentious matters related to her academic background – physics. An expert in chemistry and materials engineering, Edith Sokol is the first port of call not only for global corporations but also leading Israeli universities. “Edith is a distinguished, hands-on, dedicated professional who knows how to build a strategy for IP protection worldwide. Above all, she has the skills and sensitivity to assist in defusing delicate situations, and is always pleasant and charismatic.” Excelling in a slew of complex technical fields – applied physics, microelectronics and electro-optics – Myriam Schnur draws on her 15 years of IP experience to draft, prosecute and manage technology-related patents.
