PCT & Foreign Patent Services


Krivoshik LLC has two decades of experience in Patent Cooperation Treaty (PCT) filing and prosecuting international patent applications (PCT, EPO and Unitary Patents) and supporting the prosecution of corresponding national stage foreign applications.


Entry into the US national phase for a foreign patent application, including handling all stages of subsequent prosecution is available to our foreign clients.


I keep abreast of the continuously changing international patent law and am skilled in educating our clients to recognize and protect emerging and potentially new protectable technologies. 


The growth of global markets requires every client to consider the protection of its invention outside the United States.  We design each client’s foreign patent portfolio to assure proper protection in the appropriate countries.  In addition, the firm coordinates the domestic and foreign prosecution effort to maximize coverage and minimize conflicts and costs during prosecutions.


I also have extensive experience in preparing and filing US National Phase entry claiming priority to foreign patent applications for US & foreign clients.


Please contact me at to discuss your Foreign Patent requirements.
