Profile

Glenn Westreich has more than thirty years of experience in representing technology companies at trial in the Federal and state courts and International Trade Commission. A true first chair trial lawyer, Glenn has represented clients in litigation involving patent, copyright and trademark infringement, trade secrets, bankruptcy, and general commercial litigation.

Having grown up in Silicon Valley, attended college and law school at UC Berkeley, and practiced law in the Bay Area his entire career, Glenn is intimately familiar with the evolution of both the technology industry and the legal environment in which it operates. Glenn spent the first 20 years of his career with a Bay Area boutique law firm, typically trying at least one case a year before juries, judges and arbitrators.  As a result of his extensive experience and consistently innovative approach, Glenn’s clients rely on him to provide thoughtful and creative counsel, as well as assertive advocacy.

Like the technology industry itself, Glenn’s practice increasingly involves both domestic and international parties. Most recently, Glenn lead a trial team that successfully obtained a jury verdict in a trademark dispute for Chinese and American clients that was the culmination of five years of litigation in Oregon, California and China (all the way to the Chinese Supreme Court).

Representative recent matters include prosecution of patent infringement cases involving electronic devices, search and catalogue aggregation software, plasma etch reactors for semiconductor fabrication systems, and digital scanning technology; defense of patent infringement and trade secret misappropriation cases involving digital editing and transmission of images, electronic books, optical endpoint detection systems, integrated circuits and related software, and underground cable locators; prosecution and defense of breach of contract claims regarding provision of Internet services totaling more than $200 million; and counseling and enforcement of patent portfolios in the areas of search technology, online advertising, and digital media.

Glenn is a frequent speaker on patent and technology issues. Recent addresses include presentations at the Advanced Patent Law Institute and IP Counsel Summit in Silicon Valley. In October 2014, Glenn participated in a panel titled, "Defending Against Infringement Claims from Operating Companies" at the IP Strategy Summit in Palo Alto, CA.
