1 case as defendant.
Implicit, LLC is a private company that operates as a non-practicing entity (NPE), also known as a patent assertion entity. Information regarding its headquarters, founding date, and employee or revenue size is not publicly available. The company holds patents that originated with its predecessor, BeComm Corporation, whose employees were the named inventors on at least some of the patents Implicit has asserted.
As a non-practicing entity, Implicit, LLC does not manufacture products or offer commercial services. Its business operations are focused on acquiring and enforcing patent portfolios through litigation and licensing agreements. The company has asserted patents covering a range of technologies, including methods for "synchronization of content rendering," which is critical for multi-room audio systems, as well as server-side technologies like application architecture, client-server communication, and data management.
The company's litigation posture is that of a patent asserter. The provided case list shows two plaintiff cases in U.S. District Court and one case as a defendant before the Patent Trial and Appeal Board (PTAB). This pattern is typical for an NPE, where the PTAB appearance is often the result of an accused infringer (in this case, Sonos) challenging the validity of the asserted patents. Implicit has been described as a "serial litigant" that pursues infringement actions against numerous technology companies, often resolving cases through confidential settlements. The company has filed suits in jurisdictions including the U.S. District Court for the District of Delaware.
Implicit's most prominent legal dispute was with audio company Sonos, Inc. In 2017, Implicit sued Sonos in Delaware for patent infringement. Sonos responded by successfully challenging the validity of two Implicit patents at the PTAB, which found the claims unpatentable. Following a complex series of appeals, the U.S. Court of Appeals for the Federal Circuit affirmed the PTAB's invalidity decision in March 2026, ending that dispute in Sonos's favor. Implicit has also filed infringement suits against other technology companies, including D&M Holdings, Hulu, and Wayfair.
Sonos filed an IPR challenging the validity of claims of US8942252B2 and a related patent. In a final written decision, the PTAB found the challenged claims of US8942252B2 to be unpatentable.
