Timothy B. Yoo is a go-to first-chair trial lawyer specializing in technology and intellectual property disputes.
For three consecutive years, the Daily Journal has identified Timothy as one of the “Top Intellectual Property Lawyers” in California. He has also been recognized as an “Intellectual Property Trailblazer” in the U.S. by the National Law Journal. Additionally, in 2023, he was recognized by the Century City Bar Association in Los Angeles as its “Trial Lawyer of the Year.”
Due to his ability to understand complex technical concepts quickly and to solve complicated problems efficiently, Timothy has been sought out by clients across various industries, from emerging to global Fortune 500 companies, to handle their most significant complex matters. For example, his recent representations include the defense of the world’s largest electronics contract manufacturer in an arbitration proceeding over atmospheric water generating technology, defending the world’s second-largest memory chip maker in a $175 million breach-of-contract lawsuit brought on behalf of Microsoft over the supply of DRAM chips for Xbox One, advising industry-leading OTT streaming content providers in several patent-infringement disputes across the U.S., and representing Korea’s largest OEM automotive supplier in a global patent-infringement dispute over on-board chip technology. In 2023, Timothy attained a complete defense verdict against claims of trademark infringement and tortious interference in a two-week federal jury trial on behalf of his consumer-credit fintech client.
Before joining Bird Marella, Timothy spent two years as the head of international disputes for Korea’s largest entertainment and media conglomerate, CJ Entertainment & Media, in Seoul, Korea. Based on that experience, a substantial portion of his current practice involves assisting Asian companies in traversing cross-border disputes and advising entertainment and technology companies on defending and asserting their intellectual property rights in the U.S. For example, Timothy currently represents global K-pop stars BTS and their record label, HYBE, as well as Kakao Entertainment, TV Chosun Corp., MBC, NHN Bugs, and others in copyright matters in the U.S.
He is co-chair of Bird Marella’s Korea Practice Group.

Notable Matters

Won copyright-infringement lawsuit on behalf of international K-pop sensation BTS and its label, HYBE Corporation. The plaintiff alleged that the idea for CJ E&M and HYBE’s reality show I-Land was stolen from a written treatment for his original television series idea. The district court granted Timothy's first motion to dismiss without giving the plaintiff leave to amend—concluding that plaintiff’s claims failed as a matter of law—and entered judgment in favor of his clients. Bryan Kahn v. CJ E&M, BTS aka Bangtan Boys, and Big Hit Entertainment Company, Case No. 2:21-cv-03230-DMG-KS (C.D. Cal).
Successfully defended Humax USA, Inc., a set-top box and wireless router distributor, in a patent-infringement lawsuit in the District of Delaware. Plaintiff had alleged that Humax USA’s products infringed on its patents purporting to cover port-triggering functionality.

Won copyright-infringement lawsuit in favor of a joint defense group comprised of some of Korea’s largest media companies – Kakao Entertainment, Genie Music, NHN Bugs, TJ Media, Keum Young, MBC, and TV Chosun – concerning the works of South Korean composer Jae-Ho Lee. Successfully prevailed on successive motions to dismiss, securing a dismissal with prejudice. Beom Su Lee v. TV Chosun, et al., Case No. 2:22-cv-00933-DSF-KS (C.D. Cal.).

Elite Educational Advisors, LLC, TTAB Opposition No. 91270898, and a district court action against another competitor resulting in that competitor’s agreement to rebrand entirely.
As co-lead trial counsel, achieved a complete defense verdict on behalf of his client SK hynix, the world’s second-largest memory chip manufacturer, after a three-week jury trial in the Western District of Washington in a $175-million breach-of-contract lawsuit brought on behalf of the Microsoft Corporation by its subsidiary insurer.

As lead trial counsel, recovered millions on behalf of his LED-display manufacturer client Galaxia Electronics Co., Ltd. in a breach-of-contract case. Timothy successfully petitioned the court for a Right to Attach order—an extraordinary pre-judgment remedy that allowed Galaxia to attach millions’ worth of defendants’ assets, including bank accounts and inventories. After having its bank accounts seized, the primary defendant filed for Chapter 7 bankruptcy. Following a vigorous pursuit of the debtor in that bankruptcy action, including extensive document discovery and a Rule 2004 examination of the company’s principal, Timothy was able to secure the recovery of several millions from the debtor’s bankruptcy estate. Galaxia Electronics Co., Ltd. v. Luxmax, U.S.A., et al., Case No. 2:16-cv-05144-JAK-GJS (C.D. Cal.).
Completely defended a $50-million copyright-infringement lawsuit on behalf of his client CJ Entertainment & Media, Korea’s largest media conglomerate, concerning the distribution of “K-pop” songs in the U.S. over the Beats Music platform. Prior to the commencement of extensive international discovery, Timothy was able to get the case dismissed in its entirety based on the doctrine of forum non conveniens, which the Ninth Circuit has noted is an “exceptional” remedy that is rarely to be used. DFSB Kollective Co. Ltd. v. CJ E&M, Inc., et al., Case No. 2:15-cv-01650-SVW-FFM (C.D. Cal.).
