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

The patent infringement litigation Mesa Digital LLC v. [LG Electronics U.S.A., Inc.](/litigations/by-defendant/LG%20Electronics%20U.S.A.%2C%20Inc.), 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.

Key Legal Developments and Outcome:

• Filing & Initial Pleadings (Complaint, Answer, Counterclaims):

  • 2019-11-04: Mesa Digital LLC filed the complaint against LG Electronics U.S.A., Inc. alleging infringement of U.S. Patent No. 9,031,537. The patent generally covers multi-protocol wireless handheld multimedia device technology, including cellular, Wi-Fi, and short-range wireless standards such as Bluetooth.

• Pre-trial motions of substance: Information regarding substantive pre-trial motions such as motions to dismiss, transfer, or stay for this specific case is not readily available in the provided search results. However, similar cases involving Mesa Digital and patent 9031537 have seen various outcomes, including voluntary dismissals.

• Claim construction (Markman) outcomes: The case was dismissed before reaching the claim construction (Markman) stage.

• Discovery milestones with strategic significance: There is no publicly available information in the provided search results about specific discovery milestones in this case.

• Trial events, verdict (if any), and post-trial motions: The case did not proceed to trial.

• Settlement, dismissal, judgment, or appeal – the final disposition:

  • 2020-11-20: The case was dismissed with prejudice. The exact terms of the dismissal (e.g., voluntary dismissal by stipulation, court-ordered) for this specific case were not detailed in the provided search results, but "dismissed with prejudice" indicates that Mesa Digital cannot refile the same claim against LG Electronics concerning patent 9,031,537. Other cases involving Mesa Digital and the same patent have concluded with voluntary dismissals with prejudice, often with each party bearing its own costs.

• Parallel PTAB IPR/PGR proceedings: The provided search results do not contain information about any parallel PTAB IPR/PGR proceedings specifically initiated by LG Electronics U.S.A., Inc. against U.S. Patent No. 9,031,537 in relation to this case. However, the PatSnap results mention "Mesa Digital, LLC's full litigation history covering prior enforcement, licensing activity, and inter partes review proceedings" in a general context, suggesting that IPRs may have occurred in other disputes involving this patent.

I'll search several angles to find press coverage of this case.

Press coverage of Mesa Digital v. LG Electronics

There is effectively no mainstream or trade press coverage of this specific case. Searches across the case caption, the parties' names, and the asserted patent (U.S. 9,031,537) returned no Reuters, Bloomberg Law, Law360, Ars Technica, The Verge, IPWatchdog, Patently-O, or JD Supra article reporting on a Washington Western District suit between Mesa Digital and LG Electronics. The closest thing to press treatment of the Mesa–LG dispute is a litigation-analysis piece published through Mondaq (RPX) on 2020-05-20, which discusses the Mesa Digital campaign generally and states that the LG suit "was dismissed in early December 2019 for failure to serve the complaint." That account describes an LG case asserting the '537 patent alongside two other patents from the same family, brought in May 2019 — not the case in the metadata here.

⚠️ Contradiction flag — docket number and court. The publicly indexed dockets do not match the case metadata, and the mismatch is material enough to state plainly:

• Justia Dockets and UniCourt both show W.D. Wash. Case No. 2:19-cv-01728 as Mesa Digital LLC v. HTC America Inc., filed 2019-10-25 before Judge James L. Robart, with Thomas David Hendrickson as plaintiff's counsel — not LG Electronics.
• A separate Justia docket shows Mesa Digital, LLC v. LG Electronics U.S.A., Inc. as S.D. Cal. Case No. 3:19-cv-00823, filed 2019-05-03 before Judge Marilyn L. Huff, asserting U.S. Patents 9,031,537, 9,644,444 and 10,182,144, with Todd Atkins as plaintiff's counsel.

Per my operating instructions I have deferred to the case metadata for the caption, court, case number, and patent. But readers should know that the November 2019 filing date, the 2020-11-20 with-prejudice termination, and the W.D. Wash. venue cannot be corroborated by any source I located, and the indexed record for this docket number points to HTC as the defendant. I did not find a docket entry or order documenting the terms of the LG dismissal.

The only sustained reporting on the '537 patent comes from Unified Patents, which is not a news outlet but a defensive patent aggregator publicizing its own challenges. Unified Patents reported on 2025-05-16 that it filed an ex parte reexamination against the '537 patent on 2025-05-09; Unified Patents reported on 2025-06-26 that the Central Reexamination Unit instituted the challenge on 2025-06-24, finding substantial new questions of patentability; and Unified Patents reported on 2026-06-25 that the CRU issued an Advisory Action on 2026-06-23 maintaining rejections of all challenged claims. Across those posts, Unified characterizes Mesa Digital as "an NPE and entity associated with Ortiz & Lopez, PLLC (d/b/a OL PATENTS)" and states the '537 patent "has been asserted against over 75 defendants, including Amazon, Walmart, Best Buy, Apple, HTC, LG, Gen Mobile, Nuu, and BLU Products." That is the sole press-adjacent mention of LG in connection with the patent. Notably, all of this reporting post-dates the 2020 dismissal by roughly five years and reflects Unified's advocacy posture and its own reexamination filing, not independent reporting on the Mesa–LG litigation.

Coverage of Mesa Digital's broader campaign does exist but concerns other dockets, so I note it only to be explicit that it is not about this case: Bloomberg Law reported on 2025-10-06 that Mesa "ended its lawsuit alleging Motorola Mobility LLC was infringing" the '537 patent, with a notice of dismissal without prejudice filed in the Northern District of Illinois; Ramey LLP issued a firm press release on its December 2024 suit against BLU Products in the Southern District of Florida; and PatSnap published litigation analyses of Mesa Digital v. Best Buy/Bullitt Mobile (PatSnap) and Mesa Digital v. Quanta Computer (PatSnap), the latter noting a 55-day cradle-to-close timeline and a Rule 41(a)(1)(A)(ii) stipulation expressly "WITHOUT PREJUDICE as to the asserted patent." Those pieces discuss the settlement dynamics of comparable Mesa Digital dismissals — settlements reached, each side bearing its own fees, no public damages figures — but none reports on LG.

Bottom line: I found no damages figures, no settlement amount, no executive statement, and no industry reaction reported for Mesa Digital v. LG Electronics under any iteration of the case. Press attention to the '537 patent is dominated by Unified Patents' reexamination bulletins and by PatSnap/RPX docket analytics on sibling cases, and any inference that the LG matter "settled" would be speculation — the only on-point secondary account says the LG suit was dismissed for failure to serve, while the metadata here records a dismissal with prejudice more than a year after the stated filing date. I could not reconcile those accounts with the sources available.
