2 cases as plaintiff.
Kannuu Pty Ltd. is an Australian-founded technology company that provides content search, discovery, and recommendation solutions for television, over-the-top (OTT) media, and mobile platforms. Founded in 2004, the company is privately held and maintains offices in Carrollton, Texas; London, United Kingdom; and Sydney, Australia. Publicly available information regarding its employee count and revenue is limited, though one data provider lists it as having two employees.
Kannuu's technology is designed to help users quickly find content across various media environments. Its product and service offerings include cloud-based services with flexible APIs, text entry interfaces for remote controls, personalized search and recommendation engines, and metadata consolidation. The company states its patented intellectual property covers aspects of information architecture, delivery methodologies, and user interface elements, such as directional pad navigation. Its target customers include device manufacturers, service providers, and software developers.
The company has utilized patent litigation to assert its intellectual property. As indicated by the provided case data, Kannuu has acted as a plaintiff in two tracked cases and has not been a defendant. This plaintiff-only posture suggests a strategy of patent assertion. The lawsuits were filed against Samsung Electronics Co., Ltd. in the U.S. District Court for the Southern District of New York. This choice of venue was based on a forum selection clause in a non-disclosure agreement (NDA) the two companies had previously established.
The notable cases against Samsung, filed in 2019, alleged infringement of multiple patents related to search-and-navigation technology. The litigation followed unsuccessful business discussions between the two companies years earlier concerning the potential licensing of Kannuu's technology. During the court case, Samsung challenged the validity of the asserted patents by filing for inter partes review (IPR) with the Patent Trial and Appeal Board (PTAB). All five patents at issue were ultimately invalidated through the IPR proceedings.

Kannuu alleged that Samsung's Smart TVs and Blu-ray players infringed on its patents, including the '393 patent. The case was stayed pending IPR proceedings, but as of July 2025 was described as active, with the court granting Kannuu leave to file a second amended complaint to add new patents.
The district court case is ongoing and involves several patents asserted by Kannuu against Samsung for alleged infringement by various Samsung Smart TVs and Blu-ray players. U.S. Patent 11,200,252 was asserted in this action after the original complaint was filed.
