Bio Image

Justin Philpott’s practice includes patent prosecution, litigation, post-issuance review, diligence, transactions, and opinion counseling. Justin serves as co-chair of the firm’s PTAB Litigation Committee. During his more than 17-year career in intellectual property law, he has examined, drafted, prosecuted, acquired, licensed, and litigated countless patents. Justin regularly merges technical and legal analyses in complex electrical and computer arts, such as LTE and 5G wireless communications, MPEG video compression, and HDTV coding and transmission.

Justin has been named as an Illinois Super Lawyers Rising Star in 2018 and 2019. The Rising Star list represents the top 2.5 percent of attorneys in each state.

Before joining Banner Witcoff, Justin counseled clients for 10 years in the IP group of a global general practice law firm. He represented clients in patent matters before district courts, the International Trade Commission in Section 337 investigations, and the U.S. Patent and Trademark Office in both pre-grant and post-grant proceedings. He successfully argued motions in federal court, took and defended numerous depositions of fact and expert witnesses, and led settlement conferences to obtain litigation-ending settlements with favorable results for clients.

As a former U.S. patent examiner, Justin brings a unique perspective to patent drafting, prosecution, and analysis. At the U.S. Patent and Trademark Office, he examined and conducted searches for hundreds of patent and PCT applications in multiplex communications. Justin’s patent analysis and prosecution experience complements and informs his litigation and transactional matters, and vice versa, offering “big picture” views for cohesive and strong IP protection.

Over the course of his career, Justin has volunteered to represent pro bono clients in a variety of matters beyond patents. For example, he successfully appealed a group of Boy Scouts’ asylum denials in a case that has been cited in a leading international textbook on refugee law. Hathaway et al., James C., “The Law of Refugee Status,” Cambridge Univ. Press, 2nd Ed. (2014), 170, n. 506 (citing Kiegemwe v. Holder, 427 Fed.Appx. 473 (6th Cir. 2011)). Justin also has resolved legal disputes in copyright and employment matters on behalf of pro bono clients through “Lawyers for the Creative Arts” and the Northern District of Illinois’ “Settlement Assistance Program for Pro Se Litigants.”

Justin earned his B.S. in Electrical and Computer Engineering, with high honors, from Rutgers University, and his J.D. from Georgetown University. He is admitted to practice in the state of Illinois and the U.S. Patent and Trademark Office.

Justin practices in the Chicago office of Banner Witcoff.
