Jenner & Block

Brent Caslin manages commercial and intellectual property disputes across the United States and around the Pacific Rim.  He has tried civil and criminal cases, argued before state and federal appellate courts, and represented clients in domestic and international arbitration tribunals.

In 2009, Brent and one other partner opened Jenner & Block’s Los Angeles office.  The office has focused on quality lawyers and clients, growing from two lawyers to almost 60.  During this time, Brent’s practice has focused largely on commercial and intellectual property cases involving corporations and governments.  He has helped resolve disputes in almost every industry, for clients from the United States and Japan.

Brent has played a leading role in several of the most prominent trade secret matters in recent US history, including Move, Inc., National Association of Realtors, et al. v. Zillow, Inc., et al. ($130 million settlement in Seattle, Washington) and Epic Systems Corp. v. Tata Consultancy Services, et al. ($940 million jury verdict in Madison, Wisconsin).  In 2017, he received a prestigious California Lawyer “Attorney of the Year” (CLAY) award in the trade secret category for his work on these cases.

Media and legal organizations regularly comment favorably on Brent’s work.  He has been identified by The Legal 500, most recently in 2017, as a quality partner with a “proven track record,” and by other publications as a “Rising Star” and “Super Lawyer” in business litigation.  Martindale-Hubbell awarded Brent its highest peer recognition rating for legal ability and ethical standards.

Although a US-trained lawyer, Brent has substantial international experience.  He has lived and worked in Asia, Europe and the United States, and regularly handles cross-border disputes and investigations.  In 2003 and 2004, an attorney exchange program allowed Brent to work on international legal matters with Mori Hamada & Matsumoto, a law firm in Tokyo, Japan.  He served the State Bar of California’s International Law Section in a number of support and leadership roles, and was elected chair of the section for the 2011-2012 term.

In addition to practicing law, Brent taught an intellectual property course as an adjunct professor at the Pepperdine University School of Law from 2004 until 2012. 

Brent previously served in the US Army, with the 212th Field Artillery Brigade (now part of the 1st Armored Division).  He has a high-level security clearance.

He is licensed to practice in all state and federal courts in Washington and California.
