Mitch Yang, a former patent examiner with the U.S, Patent and Trademark Office who received his J.D. from the George Washington University School of Law and his B.S. in Electrical Engineering from the University of Maryland, has extensive experience with a wide array of technologies. He regularly handles IPR proceedings in addition to patent enforcement litigation. Victor Hardy, who received his LLM from Harvard and his J.D. from the University of Texas School of Law, has extensive experience in patent valuation, due diligence and acquisition, in addition to patent enforcement litigation and IPR proceedings. Bill Parrish, who received his J.D. from the University of Texas School of Law has handled numerous trade secret, trademark, copyright, and unfair competition cases, in addition to his work on patent cases.

We understand that patent litigation can often be too expensive for small patent owners to effectively protect their rights through traditional IP law firms. That is one reason why, in appropriate circumstances, HPY offers contingent fee, fixed fee, and/or mixed contingent / hourly fee options. Unlike many large firms, HPY has the ability to be flexible on fees. We will explore with you the different alternative fee arrangements that fit your needs.

We serve our clients all across the United States.
