Alexander E. Gasser

Senior Counsel

Alexander Gasser is a registered patent attorney with more than fifteen years of litigation experience who focuses on patent litigation in U.S. district courts and advising companies how to assert their rights and/or reduce their exposure to existing and potential intellectual property litigation. He has represented clients in patent infringement and adversarial licensing disputes involving pharmaceuticals (including Hatch-Waxman litigation), biotechnology, semiconductors, LCD technology, natural language processing, and consumer electronics.

Prior to joining Skiermont Derby LLP, Alex was a senior litigation associate at Oblon Spivak LLP, an internationally renowned litigation and patent prosecution boutique. He is experienced in all aspects of fact and expert discovery, motions, hearings, pre-trial, trial and appellate matters. His work has included coordinating the strategies of related litigations in the U.S., Japan, and Europe. Alex’s work included patent prosecution in the chemical arts and meeting with U.S. Patent Office examiners to advance the granting of patents. He has regularly prepared opinions and advised clients on mitigating risk through freedom-to-operate, invalidity, and non-infringement opinions. Alex also counsels clients on commercial transactions, including IP licensing, assignments, supply contracts, and due diligence with respect to purchases, mergers, and investments in companies.

Alex has advised clients on inter-partes review proceedings, which challenge the validity of issued patents before the U.S. Patent & Trademark Office. He has co-authored several chapters concerning IPRs in the treatise, “Post-Grant Proceedings Before the Patent Trial and Appeal Board,” published by Practicing Law Institute.

Alex has also worked on numerous patent interferences in the chemical and pharmaceutical fields, and related district court actions. Over the years, he has published more than 200 articles reporting on and analyzing trademark, copyright, trade secret, and patent litigation before the International Trade Commission on an ITC blog.

Alex lived in Switzerland, Germany and Belgium for 18 years and is fluent in German.
