Patent Services for Inventors and for Business

I am Robert J. Yarbrough, Attorney at Law, providing patent law services to clients nationwide.  I am a partner in the law firm of Lipton, Weinberger & Husick, which specializes in patents and other intellectual property. 

Big Firm Quality, Small Firm Costs

I am a former big firm lawyer, as are most of the attorneys of Lipton, Weinberger & Husick.  We provide the quality of a large law firm with the reduced costs of a small law firm.  Every client is important to me and every one of my clients receives my personal attention.

I am a degreed mechanical engineer and my particular talents and abilities are in the mechanical, electrical and aeronautical arts.  I especially enjoy working with family-owned businesses of 10 to 50 employees that rely on technical innovation for a competitive edge.   If you don't meet this description, call anyway.  If I'm not the best person for your project, I'll tell you so and refer you to an appropriate provider.
