New Patent Litigation
TS-Optics Corporation has filed a Central District of California complaint against Microsoft (8:24-cv-01974), targeting the provision of XBOX-series consoles that include certain disk drives, as well as the XBOX Cloud Gaming service, which supports the XBOX Touch Controls feature.

Federal Circuit Unwinds Noninfringement Rulings That Ended ParkerVision Case
Patent Litigation Feature
In March 2022, the Middle District of Florida dismissed the second of two cases filed by ParkerVision, Inc. against Qualcomm, ruling in part that certain infringement claims were barred due to collateral estoppel because the patents were too similar to others that Qualcomm was found not to infringe in a first suit. However, the Federal Circuit has now reversed and remanded this and other holdings by the lower court in a September 6 precedential decision, concluding that the district judge erred by failing to adequately compare the language of the claims at issue in the two actions. Among other issues, the appellate court also tackled a previously unresolved question over collateral estoppel based on Patent Trial and Appeal Board (PTAB) decisions where the challenged claims survived review.

Motion for Convenience Transfer Passes Three Year Anniversary
In Case You Missed It
Red Rock Analytics, LLC sued Apple and Qualcomm in April 2021 in the Western District of Texas. In August of that year, the defendants filed a motion to transfer venue for convenience to the Northern District of California. Claim construction briefing has gone into the court, but in June 2022 District Judge Alan D. Albright stayed proceedings pending resolution of the motion to transfer, the Federal Circuit having warned that the merits of a case should not be touched until threshold matters, like a convenience transfer request, are decided. On the third anniversary of its filing, the defendants’ transfer motion has been briefed through sur-sur-reply, with four subsequent supplements having been filed, the fourth in March 2024. Since then, the docket has been quiet.

AICP Sues United Microelectronics on Heels of Hitting TSMC
New Patent Litigation
Last month, Advanced Integrated Circuit Process LLC (AICP) filed its first lawsuit, accusing TSMC of infringing seven patents that the plaintiff received from Winbond Electronics (Nuvoton Technology Corporation Japan) in late July 2024. Now, AICP has filed its second, asserting the same seven semiconductor fabrication patents against United Microelectronics (2:24-cv-00730), in another Eastern District of Texas complaint, this one targeting the provision of semiconductor devices manufactured at various process nodes (i.e., the 22 and 28 nanometer process nodes), as well as third-party components—including those manufactured by Microsemi and Qualcomm—that incorporate the accused semiconductor devices.

Active Wireless Asserts Its Other Two Former FGI Patents
New Patent Litigation, TPLF
Funded plaintiff Active Wireless Technologies LLC has filed a second pair of Eastern District of Texas suits, one against each of Deutsche Telekom (T-Mobile) (2:24-cv-00723) and Verizon (Verizon Wireless) (2:24-cv-00724). In the ongoing litigation, in which Ericsson and Nokia have intervened, Chief Judge Rodney Gilstrap denied as premature motions to stay in light of inter partes review (IPR) of the asserted patents—the PTAB has yet to return institution decisions in response to the petitions filed. All the patents here in suit were received from FG Innovation Company Ltd. (f/k/a FG IP Innovation Company Ltd.) (FGI).

Patents with Prior “Third Iris” and “Promise to Assign” Problems Back in Litigation
New Patent Litigation
VIAAS, Inc. has filed a second complaint against APT Group Holdings (Vivint Smart Home) (2:24-cv-00713), this one in the Eastern District of Texas. In April 2023, Western District of Texas Judge Kathleen Cardone dismissed without prejudice the first case—as well as parallel suits against each of ADT, Alphabet (Google), Amazon (Ring), APT Group Holdings (Vivint Smart Home), and Cisco—all over the same two patents asserted again here, for lack of standing, ruling that VIAAS failed to meet its burden to prove that it actually owned those patents. While refusing a request to impose sanctions in the earlier litigation, Judge Cardone did admonish counsel, William P. Ramey III (identified again on the new complaint, as colead counsel), “that he has a duty to conduct a diligent investigation prior to initiating any lawsuit, and that he may not knowingly persist with cases that he learns to be baseless”.

Red Hat Seeks DJs of Noninfringement, Abusive Patent Assertion
New Patent Litigation, TPLF
Red Hat (5:24-cv-00505), acquired by IBM in 2019, has filed an Eastern District of North Carolina complaint against Competitive Access Systems, Inc. (CAS), asserting a claim under that state’s bad-faith patent assertion law, the North Carolina Abusive Patent Assertion Act (APAA), and seeking a judgment of noninfringement for its Linux products. The seven patents at issue broadly relate to networking, including network path optimization, bandwidth sharing, and/or multiple links between a source and destination for bonded data transmission.

East Texas Judge and Jury Perform an Alice One-Two Step
Patent Litigation Feature, TPLF
Last October, an Eastern District of Texas jury returned a mixed verdict awarding Ollnova Technologies Limited $11.5M from defendant Generac Holdings (ecobee) as a “lump sum royalty for the life of the patents” found infringed. A question concerning the second step of the Alice analysis of one of the patents-in-suit was submitted to that jury, which answered in Ollnova’s favor. Through its posttrial motions, ecobee asked Chief Judge Rodney Gilstrap to enter judgment as a matter of law in its favor as to that patent. The court has now refused, indicating that while the court ruled that its asserted claims—each considered “as a whole”—are drawn to an abstract idea as a matter of law, the jury considered the elements of those claims—individually or as an ordered combination—and reasonably found that ecobee failed to prove everything there to be merely conventional.

BiTMICRO Returns to Litigation
New Patent Litigation
BiTMICRO, LLC has sued Western Digital (8:24-cv-01903) in the Central District of California, targeting the provision of solid state drives (SSDs) with certain encryption features, those using the NVMe protocol, and those with SLC caching functionality, as well as NVMe-oF (NVMe over Fabric) storage platforms. Four patents, familiar to this campaign, are asserted; the plaintiff describes them as relating to “groundbreaking improvements to memory controllers, mapping tables for memory devices, NVMe over Fabrics technologies, and data security”. BiTMICRO has yet to file its certification of interested parties in connection with the new case, but it has previously identified its members, in connection with a case transferred to the Northern District of California.

Daedalus Blue Opens Third Litigation Campaign
New Patent Litigation
Daedalus Blue LLC has filed a District of Delaware complaint against Dropbox (1:24-cv-00998), alleging infringement of three former IBM patents through the provision of various products, including the Dropbox API, Magic Pocket storage system, and Nautilus search engine. At issue are features such as the support for file management and OAuth 2.0. The plaintiff pleads that the asserted patents have been licensed to “many companies”, including Amazon, Oracle, and Dropbox itself, but that “that license expired”.
