1 case as defendant.
THROUGHTEK TECHNOLOGY (SHENZHEN) Co Ltd is a branch of ThroughTek Co., Ltd. (often referred to as ThroughTek or TUTK), an AIoT (Artificial Intelligence of Things) cloud platform service provider. While its specific headquarters is in Shenzhen, China, the parent company, ThroughTek Co., Ltd., was established in July 2008 and is headquartered in Taipei, Taiwan. ThroughTek Co., Ltd. is publicly traded on the Taipei Exchange under the ticker TPEX:6565. Some sources indicate the Shenzhen entity as "deadpooled" as of April 2026, though other information suggests ongoing operations and product showcases by the broader ThroughTek entity.
The company specializes in P2P (peer-to-peer) connectivity software technology and operates the "Kalay Platform," which provides video-related cloud services. ThroughTek's product offerings include the Kalay Cloud VMS (Video Management System), DMP (Data/Device Management Platform), Cloud Recording, and various smart home solutions for devices like doorbells, baby monitors, and pet cameras. As of June 2025, over 140 million devices worldwide were authorized to connect and operate in the cloud via ThroughTek's technology.
In terms of patent litigation, THROUGHTEK TECHNOLOGY (SHENZHEN) Co Ltd has been tracked as a defendant in one case before the Patent Trial and Appeal Board, specifically "Unified Patents v. THROUGHTEK TECHNOLOGY (SHENZHEN) Co Ltd et al." The broader ThroughTek Co., Ltd. entity, however, has an active posture in protecting its intellectual property. It has been granted 80 patents in multiple countries covering P2P connectivity and cloud-based platform architecture. ThroughTek Co., Ltd. has initiated legal actions against companies for infringing its P2P patents, with at least one public settlement involving a global leader in consumer electronics peripherals. Additionally, ThroughTEK Co., Ltd. has been involved as a plaintiff in patent infringement lawsuits in the District of Delaware, such as "ThroughTEK Co., Ltd. et al v. Reolink Innovation Inc. et al."
Unified Patents filed an inter partes review petition (IPR2025-01327) challenging US patent 9727655, which has been instituted by the PTAB.
