Justinas Jarusevicius

Justinas Jarusevicius is a Partner at Motieka & Audzevicius, specializing in dispute resolution with a notable focus on intellectual property and technology-related litigation. His practice encompasses commercial litigation and arbitration, particularly for US-related legal matters, leveraging his admission to the New York State Bar. His firm's intellectual property practice includes trademark and patent protection, licensing, and enforcement, serving sectors such as Technology, Media & Telecommunications, and Pharma & Biotechnology.

In his patent litigation practice, Mr. Jarusevicius primarily represents defendants, as indicated by four defendant-side appearances compared to one plaintiff-side appearance in tracked cases. He has significant experience in US patent litigation, notably representing defendants Teso LT, UAB, Oxysales, UAB, and Metacluster LT, UAB (collectively "Oxylabs") in Bright Data, Ltd. v. Teso LT, UAB et al. in the Eastern District of Texas. In this case, a jury found his clients willfully infringed Bright Data's patents related to data communication and residential proxy solutions, awarding Bright Data approximately $7.47 million in lost profits. In a related Federal Circuit appeal (23-2147), involving some of the same defendant entities, a Bright Data patent (US11044344B2) was successfully challenged and affirmed as unpatentable, resulting in a win for the defendant side. He also appeared as counsel in the Federal Circuit case 23-2443 on the defendant side.

Mr. Jarusevicius demonstrates regular experience with Patent Trial and Appeal Board (PTAB) proceedings, having appeared as local counsel in IPR2022-00135 (defendant side) and as counsel in IPR2020-01266 (both plaintiff and defendant sides).

He holds an LL.M. from Harvard Law School and a PhD and LL.M. from Vilnius University. He is a sworn member of the New York State Bar and has been practicing as an attorney since December 15, 2016.
