Four Pennsylvania intellectual property lawyers ranked among top IP attorneys nationally

PHILADELPHIA (June 2023)Panitch Schwarze Belisario & Nadel LLP is pleased to announce that the firm and intellectual property attorneys Martin G. Belisario, Erin M. Dunston, Jeffrey W. Gluck, Ph.D., and Philip L. Hirschhorn were included in the 2023 IAM Patent 1000, a guide to the firms and attorneys deemed outstanding in the field of patent law.

Belisario assists clients in nearly all aspects of intellectual property law, including patent and trademark procurement; trade secret protection; development and implementation of IP licensing and monetization strategies; advice and opinions relating to issues of patentability, freedom to operate, and infringement; and challenging, defending, and enforcing IP rights in litigations in court and before the USPTO.

Dunston focuses her practice on patent procurement, opinions, enforcement (both in district courts and before the Patent Trial and Appeal Board), and portfolio strategy. She primarily handles matters in the life science space (small molecules, large molecules, and medical devices), but she has handled projects on subject matter ranging from precipitated silica to vaccines to radiotherapy devices.

Gluck’s legal practice spans a broad range of areas, including patent application and prosecution, IP counseling, providing legal opinions, serving on litigation teams, and appellate litigation. He is a frequent author and speaker on matters relating to patent law and software IP law. His engineering experience includes roles in industry, academia, and government, and he has authored numerous technical papers.

Hirschhorn is an experienced trial lawyer specializing in patent litigation and other intellectual property proceedings, including post-grant proceedings before the Patent Trial and Appeals Board of the USPTO. His extensive experience, spanning more than 30 years, includes bench trials, jury trials, PTAB proceedings, and arbitrations.

The IAM Patent 1000 is commonly regarded as the definitive ‘go-to’ resource for those seeking to identify world-class, private practice patent expertise and leading expert witnesses in the US. The 2023 rankings are the result of an exhaustive qualitative research project to identify outstanding firms and individuals across multiple jurisdictions. Firms and lawyers are ranked according to the following criteria: depth of knowledge, market presence, level of work, and positive peer and client feedback.
