The complaint

Malikie Innovations Ltd. and Key Patent Innovations Ltd. v. Ubiquiti Inc. f/k/a Ubiquiti Networks, Inc., No. 1:26-cv-11017 (N.D. Ill., Eastern Division), is a twenty-three-page complaint for patent infringement filed September 10, 2026, ECF No. 1, with a jury demand. Malikie describes itself as the successor to a portfolio created by a prior owner, and Key Patent Innovations as the beneficiary of a trust under which Malikie holds the patents. The complaint alleges, on information and belief, that Ubiquiti is a Delaware corporation with a regular and established place of business in Chicago, Illinois.

What the patents cover

U.S. Patent 7,747,934 is titled Method for selecting low density parity check (LDPC) code used for encoding of variable length data and issued June 29, 2010. Claim 1 covers a method of selecting a low-density parity-check (LDPC) code for encoding variable sized data by providing LDPC codes of different codeword lengths and code rates, calculating the number of shortening bits and puncturing bits for each, providing a performance criterion, determining in a computer processor a selected code from the shortened and punctured codes that meets the criterion, and encoding data with it.

The complaint also asserts U.S. Patent 9,615,311 (Methods and apparatus for the communication of cellular network information between a wireless local area network and a mobile station), U.S. Patent 9,615,383 (Negotiation of quality of service (QoS) information for network management traffic in a wireless local area network (WLAN)), and U.S. Patent 10,778,989 (Rolling intra prediction for image and video coding).

What the lawsuit is about

Malikie alleges direct, induced, and contributory infringement of at least claims 1 and 10 of the '934 patent by Ubiquiti products implementing LDPC coding under IEEE 802.11, such as UniFi access points including the U6-Lite, U6-Pro, and U7-Pro; claim 1 of the '311 patent by Passpoint-compliant products; claim 7 of the '383 patent by products compliant with IEEE 802.11 standards; and claim 10 of the '989 patent by cameras that support AV1 video encoding. It alleges that the prior owner notified Ubiquiti of the '311 patent in a letter on or about March 18, 2021, and that Malikie later offered licenses, including specific FRAND royalty rates, in correspondence from October 2023 through June 2026. The prayer asks for damages, a finding that infringement of the '311 and '383 patents was willful, enhanced damages, an injunction or ongoing royalties for the '934, '383, and '989 patents, and attorneys' fees.

What to watch next

The court granted Ubiquiti an extension of time to answer on October 6, 2026 (ECF No. 19). Watch for Ubiquiti's answer or Rule 12 motion.
