About Robert Yarbrough

I have practiced law for thirty years. I specialize in business and patent law, particularly patent prosecution and helping clients protect their inventions.

I am a patent attorney licensed to practice before the United States Patent and Trademark Office and hold a degree in mechanical engineering. I am a partner in the law firm of Lipton, Weinberger & Husick, a specialty intellectual property law firm based in Southeastern Pennsylvania. I also am an environmental attorney licensed in Pennsylvania and Kentucky. In environmental matters, I am counsel to Drinker, Biddle & Reath LLP, a top-100 firm of over six hundred lawyers with offices in Philadelphia, Washington, D.C., Princeton, Los Angeles and San Francisco.

I opened my patent law office in 1998 and have practiced patent law from that time to the present. I worked in the Environmental Practice Group of Drinker, Biddle & Reath from 1996 until 1998 and in the Environmental Department of Cohen, Shapiro, Polisher, Shiekman & Cohen, a Philadelphia regional firm, from 1989 through 1995. I enforced environmental laws for the Commonwealth of Kentucky from 1977 through 1988.
