About Peter D.
Peter D. Sleman built a bridge between engineering and law early in his career. He earned a Bachelor of Science in Biomedical Engineering from Rutgers University in 2005 and took up legal studies at Seton Hall University School of Law, receiving his J.D. in 2008. Those two strands — technical training and legal education — have shaped the cases he accepts and the clients he advises.
After law school he moved into intellectual property work. His registration as a patent lawyer before the United States Patent and Trademark Office marks a central credential. That registration allows him to prepare and prosecute patent applications on behalf of inventors and companies. His background in biomedical engineering helps him translate technical concepts into the legal and procedural language required by patent examiners.
Sleman is admitted to practice in both New York and New Jersey. He has worked on matters that span patent prosecution, patentability assessments, and opinions on freedom-to-operate. He also assists clients who need clarity about patent strategy during product development. His technical training makes him comfortable reviewing laboratory results, device schematics, and engineering drawings when forming legal positions.
His current office is at Sleman & Lund LLP. There he works alongside colleagues who handle related aspects of intellectual property and commercial law. He represents individual inventors, startups, and established firms. His role involves drafting patent applications, responding to office actions, and advising on prosecution strategy. He also coordinates with outside counsel when matters require litigation or specialized technical experts.
He maintains current membership in professional associations relevant to patent and intellectual property practice. That membership keeps him connected to peers, emerging case law, and changes at the USPTO. He also pursues continuing education that reflects both legal developments and advances in biomedical technology.
Clients and colleagues describe his approach as methodical. He reads technical material closely, frames legal questions precisely, and communicates options clearly. He balances the demands of complex technical subject matter with the procedural requirements of patent practice. As of 2026 he continues to practice at Sleman & Lund LLP, concentrating on patent prosecution and related intellectual property counseling.
