Motieka & Audzevicius is a distinguished business law firm headquartered in Vilnius, Lithuania, with a single office. Founded in 1959, the firm operates as a prominent regional legal practice, recognized with a Band 1 ranking in Dispute Resolution in Lithuania by Chambers Global 2026. The firm’s expertise spans a wide range of business law areas, including a dedicated Intellectual Property practice focused on protecting and enforcing IP rights globally, alongside robust Technology, Media & Telecommunications capabilities.

In patent litigation, Motieka & Audzevicius demonstrates a primary focus on defending clients, appearing on the defendant side in four out of five tracked cases. Their practice is notably concentrated in software, computer networks, and data communication technologies, particularly concerning proxy networks and web data collection systems. The firm has represented Lithuanian entities in significant U.S. patent disputes, showcasing its capability in cross-border intellectual property litigation.

A prominent example of their patent litigation work is their representation of Teso LT, UAB, Metacluster LT, UAB, and Oxysales, UAB (collectively "Oxylabs") as defendants in Bright Data, Ltd. v. Teso LT, UAB et al. (E.D. Texas, Case No. 2:19-cv-395). In this case, a U.S. federal jury found Oxylabs to have willfully infringed Bright Data's patents related to residential proxy solutions, resulting in a damages award of $7,474,876.00 for lost profits. The firm further defended clients in related Federal Circuit appeals, including Case No. 23-2443 and 23-2147, concerning patents on faster and more efficient data communication systems. While the Federal Circuit affirmed a lower decision upholding Bright Data's patents in 23-2443, the firm secured an affirmance of unpatentability for one key patent (US11044344B2) in case 23-2147, extinguishing the plaintiff's enforcement position on that patent.

The firm actively engages in Patent Trial and Appeal Board (PTAB) proceedings, with appearances in Inter Partes Review (IPR) cases IPR2020-01266 (both as plaintiff and defendant) and IPR2022-00135 (as defendant and local counsel). These IPRs likely pertain to technologies aligned with their broader patent litigation portfolio, given their focus on software and data communication disputes.
