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.
Samsung petitioned for inter partes review of U.S. Patent No. 9,697,264 B2. The PTAB denied institution on September 22, 2020, on the merits for failure to show unpatentability.
Inter partes review petition by Samsung against U.S. Patent No. 8,676,852. The PTAB denied institution on the merits on September 22, 2020.

Samsung petitioned for inter partes review of U.S. Patent 8,370,393. The PTAB instituted review and found all challenged claims 1–16 unpatentable; the Federal Circuit affirmed in No. 22-1526, and an IPR certificate issued Feb. 9, 2024 cancelling the claims.
