Mesa Digital LLC v. LG Electronics U.S.A., Inc.

The patent infringement litigation Mesa Digital LLC v. LG Electronics U.S.A., Inc., Case No. 2:19-cv-01728, was filed on November 4, 2019, in the U.S. District Court for the Western District of Washington and was dismissed with prejudice on November 20, 2020. The plaintiff, Mesa Digital LLC, is identified as a patent assertion entity (PAE) or non-practicing entity (NPE), focused on patent licensing and enforcement through litigation. Mesa Digital LLC is associated with Ortiz & Lopez, PLLC (d/b/a OL PATENTS). The defendant, LG Electronics U.S.A., Inc., is the North American subsidiary of LG Electronics, Inc., a global technology and manufacturing innovator that sells a wide array of consumer electronics, home appliances, and commercial products.

The sole patent asserted in this case was U.S. Patent No. 9,031,537, titled "Electronic wireless hand held multimedia device." This patent broadly describes a handheld multimedia device incorporating a microprocessor and multiple wireless transceiver modules. These modules enable communication over various standards, including cellular (e.g., GSM, CDMA, GPRS, 3G), 802.11 (WLAN), and short-range technologies (e.g., Bluetooth, infrared, RFID), for the retrieval, processing, and delivery of multimedia data from remote resources like the internet and servers. The patent also mentions features such as a touch-sensitive display screen, a GPS module, and a mobile payment module. While specific accused products were not detailed in the available public records for this particular case, Mesa Digital has historically asserted this patent against smartphones and other wireless multimedia devices from various manufacturers.

The case was heard in the Western District of Washington, which has its own Local Patent Rules governing the procedural framework for patent cases. The specific judge presiding over this case was not readily identifiable in public search results. The swift resolution of the case, terminating in just over a year with a dismissal with prejudice, suggests an early settlement or a voluntary dismissal that bars Mesa Digital from refiling the same claims against LG regarding the asserted patent. This case is notable as part of Mesa Digital's extensive assertion campaign involving the '537 patent, which has been litigated against over 75 defendants, including major technology companies. Furthermore, the '537 patent faced an ex parte reexamination proceeding initiated by Unified Patents in May 2025, leading to findings of substantial new questions of patentability in June 2025, years after this particular case's dismissal.

The patent infringement lawsuit, Mesa Digital LLC v. LG Electronics U.S.A., Inc., Case No. 2:19-cv-01728, was filed in the Washington Western District Court on November 4, 2019, and was dismissed with prejudice on November 20, 2020. The asserted patent was US 9,031,537, which relates to an electronic wireless handheld multimedia device.

However, Unified Patents, in discussions about the '537 patent, states that Mesa Digital LLC is "an NPE and entity associated with Ortiz & Lopez, PLLC (d/b/a OL PATENTS)". This suggests Ortiz & Lopez, PLLC may have represented Mesa Digital LLC in this and other related matters.
