Mr. Kilyk practices exclusively in the field of intellectual property law, especially patent law. Mr. Kilyk specializes in patent post-grant review proceedings, inter partes reexaminations, interferences, and oppositions, as well as legal opinions, prosecution, and litigation matters, with specific concentration in the areas of biotechnology, chemistry, and pharmaceuticals.  Recent technologies with which he has been involved include biosimilars, new chemical compounds, nucleic acid sequences, proteins, enzymes, biomarkers, chemical and biological assays, monoclonal antibodies, cell lines, DNA cloning and amplification techniques, genetic vectors, medical treatments, pharmaceutical compositions, biofuels, chemical syntheses and reactions, and chemical surface treatments.

Mr. Kilyk has served as trial counsel in numerous patent lawsuits, including bench and jury trials before the U.S. district courts, proceedings before the U.S. International Trade Commission, and appeals before the U.S. Courts of Appeal for the Federal and Seventh Circuits.

With extensive experience in formulating patent strategies and in managing patent portfolios, Mr. Kilyk counsels and renders opinions on patent validity, patent infringement, technology licensing, and the protection of trade secrets and other proprietary information. He also prepares and prosecutes patent applications in the U.S. and foreign countries, as both independent activities and as part of coordinated overall patent strategies on behalf of clients.
