Flaster Greenberg PC: Patent Litigation Summary
May 2, 2026

Flaster Greenberg PC is a mid-sized commercial law firm with a significant intellectual property practice. Headquartered in Cherry Hill, New Jersey, the firm has offices throughout the mid-Atlantic in Pennsylvania, New York, and Delaware, as well as a presence in Florida. While not an AmLaw 200 firm, Flaster Greenberg is recognized by industry publications; its Intellectual Property department in Pennsylvania has been ranked by Chambers & Partners for over 15 consecutive years. The National Law Journal has also recognized the firm as a top mid-size law firm.

The firm’s patent litigation practice covers a broad range of technologies, including telecommunications, wireless technologies, software, artificial intelligence, medical devices, pharmaceuticals, and manufacturing. Attorneys in the practice have experience litigating in key patent jurisdictions, including the District of Delaware, the Eastern and Western Districts of Texas, and the International Trade Commission (ITC). The firm's website notes its experience representing both plaintiffs and defendants in patent infringement actions, including defending clients against non-practicing entities (NPEs). The single tracked case for the firm, Rare Breed Triggers Inc. et al. v. Nicholas Norton et al., shows a plaintiff-side representation, though the firm's broader description indicates a balanced practice.

Flaster Greenberg’s patent group includes litigators with experience in appeals to the U.S. Court of Appeals for the Federal Circuit and complex Hatch-Waxman (ANDA) cases for pharmaceutical clients. The firm also maintains a notable post-grant practice before the U.S. Patent and Trademark Office, handling inter partes review (IPR), post-grant review (PGR), and ex parte re-examination proceedings. The practice's capabilities are enhanced by the presence of a former Patent Trial and Appeal Board (PTAB) supervisory attorney. While no public data on the firm's specific filing volume is available, its website emphasizes substantial experience representing both patent owners and challengers in these proceedings.

The practice is led by experienced partners recognized in the legal industry. Michael J. Bonella, a shareholder and IP Litigation Practice Group Lead, is a first-chair litigator with over 25 years of experience and has been ranked by Chambers & Partners and IAM Patent 1000. Aakash K. Patel, another shareholder, focuses on IP litigation in the electrical, AI, semiconductor, and medical device fields and has been recognized as a "Rising Star". The IP department has seen significant growth, nearly doubling in size over the last three years as of late 2025.
