About Mr. Robert Z.
Mr. Robert Z. Cashman trained first as a student of ideas. He graduated from the State University of New York at Binghamton with a B.A. in Philosophy in 1996. He later earned a law degree from Touro College, receiving his J.D. in 2006.
Early legal work put him inside law firms and on technical files. While still a student he worked as a law intern in 2005 at Scully, Scott, Murphy & Presser. After law school he moved into patent work, joining Cardinal Law Group in 2007 where his duties included PCT matters and prior art analysis. A year later he took a role in asset acquisition, licensing, and patent prosecution at Technology, Patents, & Licensing, Inc., gaining experience on the transactional side of intellectual property.
He is registered with the U.S. Patent & Trademark Office as a patent lawyer (Reg. No. 60,246) and has been admitted to practice in New York and Texas. He also holds admission to the U.S. District Court for the Southern District of Texas. Those credentials have allowed him to work on both prosecution before patent offices and litigation-related filings in federal court.
In 2010 he established his own firm, Cashman Law Office, PLLC, and has served as owner and lawyer since then. The move into private practice followed several years of in-house and firm-side experience in patent prosecution and licensing. As a solo firm principal he manages client matters and the practical business of running a small legal office.
His matters have combined technical review and legal strategy. He has worked on patent prosecution files, handled international PCT filings, and conducted prior art searches and analyses. He has also participated in the negotiation of technology transfer and licensing arrangements, which required translating technical descriptions into contract terms and deal structures.
Colleagues and clients have come to him for hands-on work: drafting patent claims, preparing office action responses, and evaluating freedom-to-operate issues. The practice reflects the mix of litigation-adjacent federal experience and substantive patent-office prosecution.
Outside filings and registrations, he maintains bar membership and court admissions that support practice across New York and Texas and allow representation before the USPTO. He continues to combine patent prosecution, licensing, and transactional IP work in his private practice.
He currently practices at Cashman Law Office, PLLC, focusing on patent prosecution, licensing, and related intellectual property matters.
