Irina Kostko

Lawyer / Technical Consultant

Irina Kostko is a lawyer (Quebec Bar, 2014) specializing in patents. She helps inventors obtain patents in various fields of engineering, including electrical engineering, telecommunications, and information technology. For the past 7 yeas, Irina drafted and prosecuted numerous patent applications for startups, SMEs, and telecommunication and information technology giants.

Irina thrives in building and maintaining trusted relationships with inventors due to her deep knowledge and expertise in engineering, and her industrial and academic research experience. She has helped inventors from all over the world. Irina is fluent in three languages: English, French, and Russian.

Prior to attending law school, Irina designed transmitters and other devices for fiber-optic communications while working in the academia and the industry in the UK and in Canada. Irina created simulation software for optimization of high-speed telecommunication lasers. Thus, algorithms and C++ codes are not strangers to her.

Irina is a co-author of over thirty scientific publications. (That is how she became fond of technical writing.) She also lectured theoretical and practical classes in fiber optics, optoelectronics, and numerical computer simulations at Ecole Polytechnique de Montréal and McGill University.

Irina then decided to switch gears by pursuing a Bachelor of Laws degree at the University of Montreal. After graduating, she dived into intellectual property law.
