Hal is an experienced patent lawyer whose practice focuses on advocacy in the US Patent & Trademark office. His mechanical engineering experience led him to expertise in IP protection in many fields, such as packaging, robotics, power transmissions, software, consumer products, and medical devices.
Hal is an adjunct professor of law at both Temple Beasley School of Law and Drexel Kline School of law. He is the author of the most popular text used in law school for teaching patent prosecution, titled “Patent Prosecution – Advocacy in the US Patent & Trademark Office: A Casebook & Training Manual.” ( His book has been named one of the “Best Patent Law Books of All Time” by BookAuthority ( He is a frequent author and speaker, with articles on patent law in publications such as Mechanical Engineering, Packaging Digest, and others.

Before practicing patent law, Hal was a mechanical engineer working in the design and field start-up of power plant systems, air pollution control equipment, and mineral processing systems. He completed his coursework for a masters degree in mechanical engineering at Bucknell. Before joining CRK, he was a partner at an AMLAW 100 law firm, but started his career at Woodcock Washburn LLP, a premier boutique patent firm in Philadelphia, where he practiced with many current CRK lawyers

Hal believes he has taught advocacy in patent prosecution to more patent lawyers than anyone in the U.S. He has ongoing projects for explaining patenting to non-lawyers, including books and software. But Hal is at his best when solving complex problems for his clients. He states, “I am, at my core, a practicing patent lawyer built for figuring things out.”
