Stanley M. Erjavac ( Stan )

Principal / Detroit Metro Office

Stan has built his career as a patent attorney by being attentive to the needs of his clients, several of whom he has worked with for more than twenty years. His clients appreciate that he responds to their questions quickly and communicates with them on a daily basis. Before the global pandemic, Stan travelled to Japan every year to meet with his important Japanese clients face to face. Today, he regularly holds virtual meetings with all of his clients to discuss their IP portfolios and strategies for growing them.

Stan applies his former experience as an automotive engineer to provide methodical and effective counsel for managing his clients’ IP. He currently leads a team of patent attorneys who he chooses to handle specific matters on a case-by-case basis depending on their technical expertise. This customized approach leads to stronger patents and greater cost efficiency.

  • Provides patent counsel to executives, in-house counsel, engineering, and marketing teams on a regular basis, including on-site visits in the U.S. and Japan.

  • Experienced in negotiating patent licensing agreements and joint development agreements to capitalize additional revenue.

In addition to focusing on patent and trademark procurement, Stan’s practice includes drafting licensing and joint development agreements, participating in licensing negotiations, and strategic counseling.
