Connor J. Villar

Connor J. Villar is an Associate in the Litigation Department and a member of the Intellectual Property and Patent Law Groups at Proskauer Rose. His patent litigation practice focuses on technology areas including software, applications, network security measures, and a variety of medical devices. Specifically, his tracked case experience involves disputes related to medical technology, such as blood and plasma component collection systems, therapeutic apheresis, and fluid delivery devices, representing companies like Haemonetics Corporation.

Villar primarily represents patent owners in infringement disputes, as evidenced by his three plaintiff-side appearances for Haemonetics Corporation in patent infringement actions. While one appearance is listed on the defendant side within a case also involving Haemonetics, his work consistently positions him with operating companies in asserting their intellectual property rights. All his tracked appearances have been with Proskauer Rose.

His notable case involvement includes representing Haemonetics Corporation in ongoing patent infringement suits against Terumo BCT, Inc., concerning plasma donation systems, and against Fresenius Kabi USA, LLC et al., regarding medical devices and methods for managing fluid delivery. Additionally, Villar has contributed analysis on significant Federal Circuit decisions through publications on Proskauer's "The Patent Playbook" blog, including reversals related to Section 101 patent eligibility for an adjustable dumbbell system and expert admissibility thresholds in patent cases. He has also provided commentary on developments in LTE patent disputes and proposed revisions to PTAB rules.

Villar has experience with post-grant review (PGR) proceedings before the Patent Trial and Appeal Board (PTAB), having been listed as counsel for Haemonetics Corporation in a PGR proceeding initiated by Terumo BCT, Inc. He earned his J.D., magna cum laude, from Tulane University Law School and a B.Eng., cum laude, from SUNY Maritime College, and is admitted to practice in New York and before the United States Patent and Trademark Office.
