15 cases as plaintiff.
Roku, Inc. is a publicly traded technology company founded in 2002 by Anthony Wood and headquartered in San Jose, California. The company, which went public in 2017, trades on the Nasdaq stock exchange under the ticker symbol ROKU. For the trailing 12 months as of early 2026, Roku's revenue was reported to be approximately $4.7 billion to $4.97 billion, with a market capitalization of around $18.5 billion. The company has over 3,000 employees.
Roku's primary business is its television streaming platform. The company operates in two main segments: Devices and Platform. The Devices segment includes its popular streaming media players (sticks, set-top boxes) and audio products like soundbars. Roku also licenses its proprietary operating system, Roku OS, to a wide range of television manufacturers who produce Roku-branded smart TVs. The Platform segment, which generates the majority of revenue, focuses on digital advertising, content distribution, and subscription revenue sharing through The Roku Channel and the company's app store.
Based on the provided data, Roku is an operating company defending its technology in patent litigation. The company has been a defendant in two tracked cases and has not appeared as a plaintiff. This posture is consistent with a technology firm being targeted by patent holders. Both of its tracked cases were filed in the U.S. District Court for the Western District of Texas, a venue known for a high volume of patent litigation.
The two cases listed were brought by Almondnet, Inc. and AlmondNet, Inc. et al. in 2021. Almondnet describes itself as an advertising technology company that has also sued other major tech firms, such as Amazon, over patents related to targeted digital advertising. In a separate case, a jury in the Western District of Texas found that Amazon infringed on Almondnet's patents and awarded significant damages, establishing a litigious history for the plaintiff in this specific court.
