Kenneth L. Dorsney: Patent Litigation Analyst Summary

Kenneth L. Dorsney is the Chair of the Intellectual Property Practice at Morris James LLP and a registered patent attorney with more than two decades of experience, primarily focused on patent litigation in the U.S. District Court for the District of Delaware. While the tracked case list shows a single appearance as local counsel for a plaintiff, his broader practice is substantially more extensive. His work encompasses a range of technologies, with a significant concentration in the pharmaceutical sector, particularly in Abbreviated New Drug Application (ANDA) litigation under the Hatch-Waxman Act. Mr. Dorsney has written and edited multiple books for the American Bar Association on the subject of ANDA and Pre-ANDA litigation. His firm also notes experience in matters involving telecommunications and DSL technology.

Mr. Dorsney's practice involves representing both patent holders and accused infringers in the District of Delaware, where he acts as a key local resource for national and international law firms. His firm's representative matters show him acting for plaintiffs such as Amgen and for defendants in other matters. This indicates a balanced practice, serving both as an enforcer of patent rights and a defender of operating companies, which contrasts with the single plaintiff-side appearance in the provided case data. His extensive experience in Delaware federal court is a key aspect of his practice.

A longtime partner at Morris James LLP in Wilmington, DE, Mr. Dorsney is an established figure in the Delaware IP bar. He has served as past chair of the Intellectual Property sections of the Delaware State Bar Association and the Federal Bar Association's Delaware Chapter. While his publications discuss inter partes review (IPR) in the context of ANDA litigation, his public profile does not indicate a regular practice appearing before the Patent Trial and Appeal Board (PTAB).

Mr. Dorsney is admitted to practice in Delaware, the District of Columbia, and before the U.S. Patent and Trademark Office.
