James L. Davis, Jr.


James L. Davis, Jr. focuses his practice on intellectual property litigation in federal courts, as well as before the ITC and the PTAB. Applying his background in electrical and computer engineering, Jim has served as lead counsel in district court, Federal Circuit and PTAB proceedings and represented clients across a broad range of technologies including semiconductors, analog circuits, wireless technology, consumer electronics, internet services, and medical devices.

In litigating numerous cases from filing to resolution, Jim has devised and executed winning strategies for both intellectual property holders and accused infringers. Following through on these analyses, Jim has presented and cross-examined witnesses at trial, argued claim constructions, taken key depositions, obtained critical admissions and evidence, and drafted briefs that have led to victories and favorable settlements on behalf of his clients.

Before the PTAB and the USPTO, Jim has also litigated dozens of post-grant proceedings, including inter partes reviews and covered business method reviews, both on behalf of petitioners and patent owners. Jim’s efforts have resulted in favorable resolutions, including quick settlements after filing.

Jim also advises clients concerning intellectual property strategies, including acquisitions, enforcement, due diligence, and licensing.
