Firm Bio

Willenken Wilson Loh & Delgado LLP is an elite California litigation boutique handling complex litigation nationwide, including class actions, intellectual property, product liability, utilities litigation, business disputes, and white-collar criminal defense and investigations.

Founded in 2002 by former Quinn Emmanuel attorneys, the firm has grown to fourteen lawyers, with offices in Los Angeles and San Francisco. Part of the “formula” for Willenken’s success is hiring only the best and the brightest: its lawyers hail from top law schools and were trained at the country’s best BigLaw firms. Recently, Willenken was recognized by Above the Law as the second most prestigious litigation firm in the country based on the pedigree of its attorneys.

Willenken’s stellar reputation has been built on the results it gets for its clients. The firm, known for its aggressive advocacy, innovative strategy, and prowess at trial, has garnered far more than its fair share of litigation victories.

Benchmark Litigation honored the firm in 2018, describing it as “one of the most prominent litigation boutiques in the U.S.” The National Law Journal recently named Willenken as one of ten firms on its national “Litigation Boutique Hotlist” and Corporate Counsel Magazine named Willenken a “Go-To Law Firm” for Top 500 Companies.

And, Willenken’s litigation wins have earned the firm what American Lawyer referred to as an “enviable client list,” including Microsoft, Procter & Gamble, Spectrum Brands, Walgreens, Ticketmaster, Motorola Solutions, Southern California Edison, Southern California Gas, KeyBank, Sears Holdings Corporation, Pacific Gas & Electric, T-Mobile, VIZIO, among others.

Willenken is 100% minority-owned, and eight of its fourteen attorneys are women. Its lawyers are Indian-American, Cuban-American, Chinese-American, Korean-American, and Japanese-American, among other ethnicities. Cases are staffed with a diverse group of partners and associates by virtue of the composition of the firm, ensuring organic, broad-based thinking on every case, which allows the firm to build credibility with clients and juries alike.
