Jeff Joyner is a partner in Glaser Weil’s Century City office. Jeff has successfully protected and litigated key intellectual property assets for over 25 years. In addition to his focus on intellectual property, Jeff serves as a trusted advisor and outside general counsel to Fortune 100 companies, entrepreneurs, investment funds, and high-net-worth individuals on a variety of matters. His broad legal acumen allows him to address the universe of his clients’ legal and strategic business decisions.

Jeff is regularly sought after to serve as lead trial counsel in intellectual property litigation involving substantial damage claims in the U.S. and abroad, including patent, trademark, trade secret, trade dress and copyright infringement, anti-counterfeiting, reverse confusion and dilution, unfair competition, contractual, licensing, domain name, and rights of publicity disputes.

In addition, Jeff has significant experience in the execution of worldwide intellectual property development, acquisition, protection, enforcement, branding, and licensing programs for patents, trademarks, trade dress, and copyrighted works.

Jeff’s practice focuses on environmental, social, and governance (ESG) companies, including those in the climate tech, alternative energy, advanced transportation, and health and wellness industries. He also has experience in consumer products, electronics, entertainment and media, clothing and apparel, and food and beverage.

Jeff’s passion for sustainability, human rights, and emerging technologies has made him a leader at the forefront of these industries. He has advised and been an active limited partner in one of the first clean technology venture funds, which has included a portfolio of Internet protocols, efficient lighting, energy efficiency rebates, solar, carbon credit management, water purification, and biopesticide companies. He has also cofounded and cochaired alliances and foundations to help develop client industries resulting in jobs and economic growth through organizations like the Los Angeles County Economic Development Corporation.

In the entertainment industry, Jeff advises clients on matters ranging from assisting celebrities with the launch of clothing, product, and technology companies to representing music icons in copyright audits and sophisticated analysis of their estates for the exploitation of copyrighted works with a combined value in the millions of dollars.

Jeff has been instrumental not only as lead counsel on significant transactions and litigation, but also in supporting clients by founding coalitions advocating for policy and legislative frameworks for industry clusters, such as natural care products; advanced transportation (electric, autonomous vehicles, and smart cities); AI; blockchain; and the convergence of entertainment and media with technology, including the metaverse.
