Defendant
1 case as defendant.
Metacluster LT, UAB is a private Lithuanian entity based in Vilnius, Lithuania. While one source indicates a founding date of March 13, 2026, court records show its involvement in litigation beginning in 2019, suggesting it was active prior to that date. Metacluster LT, UAB was deregistered on January 6, 2023. As of January 2025, it was estimated to have 5 employees.
The company operated in the Custom Computer Programming Services industry. It was publicly identified as part of a collective of entities, including Teso LT, UAB and Oxysales, UAB, that operated under the name "Oxylabs." Oxylabs is known for providing residential proxy solutions and web data collection services.
Metacluster LT, UAB has solely appeared as a defendant in U.S. patent litigation, indicating a posture as an operating company defending against infringement claims. The company has no record of initiating patent lawsuits as a plaintiff. Its single tracked case was filed in the U.S. District Court for the Eastern District of Texas, a venue known for patent litigation.
The company was a defendant in Bright Data, Ltd. v. Teso LT, UAB et al., filed in the Eastern District of Texas, where it was accused of infringing U.S. patents related to residential proxy solutions. A federal jury found that Metacluster LT, UAB and its co-defendants, collectively known as Oxylabs, willfully infringed Bright Data's patent rights and awarded Bright Data $7,474,876.00 in lost profits. Separately, Metacluster LT, UAB, alongside other "Oxylabs" entities, successfully defended against another patent assertion by Bright Data concerning data communication, with the Federal Circuit affirming the unpatentability of the asserted patent in August 2025.
Bright Data asserted claims 1 and 26 of the '319 patent against Oxylabs. A jury was instructed to determine infringement and validity, and a verdict form was filed on November 5, 2021.
