J. Ricardo Cedillo

Ricardo G. Cedillo is a highly experienced trial attorney and a founding shareholder of Davis, Cedillo & Mendoza, Inc., based in San Antonio, Texas. His practice encompasses a broad range of complex litigation, with patent litigation being a significant area of focus within his intellectual property disputes work.

In his patent litigation practice, Mr. Cedillo handles cases involving sophisticated technology, as demonstrated by his representation of Greenthread, LLC in patent enforcement actions related to semiconductor devices. These disputes have centered on patents covering semiconductor devices with graded dopant regions, essential to core transistor and diode structures. While the tracked case shows a plaintiff-side appearance as local counsel, his general civil practice is noted to include representation for both plaintiffs and defendants, spanning individuals to Fortune 50 companies.

Notable engagements include his role as local counsel for Greenthread, LLC in Greenthread, LLC v. Renesas Electronics America, Inc. and related litigation, such as Greenthread, LLC v. ON Semiconductor Corporation, which was stayed pending inter partes review (IPR) proceedings before the Patent Trial and Appeal Board (PTAB). He was also involved in Greenthread, LLC v. Samsung Electronics Co., Ltd., which concluded with a confidential settlement following a favorable Markman ruling. Mr. Cedillo's involvement in cases that directly interact with PTAB proceedings indicates experience with the interplay between district court litigation and post-grant review mechanisms.

Mr. Cedillo earned his J.D. from Harvard University in 1979 and was admitted to the Texas bar the same year. He is recognized for his extensive trial expertise, having been named in The Best Lawyers in America® for Litigation - Patent and other categories, and receiving the 2023 Ronald D. Secrest Outstanding Trial Lawyer Award from the Texas Bar Foundation.
