John G. Day

John G. Day is a Director in the intellectual property group at Ashby & Geddes in Wilmington, Delaware. His practice is focused on serving as Delaware counsel in patent and trademark litigation for a wide range of national and international clients. Mr. Day has experience across diverse technology sectors, including semiconductors, medical devices, pharmaceuticals, biotechnology, consumer electronics, computer hardware and software, and telecommunications.

The attorney's single tracked appearance was as local counsel for the defendant in Greenthread Ltd v. Monolithic Power Systems Inc. While this suggests a defense-side practice, his professional biography and firm materials state that he represents both plaintiffs and defendants, which is typical for experienced Delaware local counsel. His role often involves advising clients and lead counsel from other national firms on practicing before the U.S. District Court for the District of Delaware.

Mr. Day has been with Ashby & Geddes for the entirety of his tracked patent litigation career. In his most prominent tracked matter, Greenthread v. Monolithic Power Systems, the district court case was stayed pending the outcome of inter partes review (IPR) proceedings initiated by his client at the Patent Trial and Appeal Board (PTAB). His public profiles note his service as Delaware counsel in other significant patent cases, including Idenix Pharmaceuticals LLC v. Gilead Sciences, Inc. and International Business Machines Corporation v. Groupon, Inc.

Admitted to the Delaware bar in 1985, Mr. Day received his J.D., cum laude, from Temple University and a B.A. from Gordon College. He is also admitted to practice before the U.S. Court of Appeals for the Federal Circuit.
