An Inter Partes Review petition that was terminated due to settlement on April 18, 2024.

Case overview & background

Plain-language overview of the case: parties, accused product, patents at issue, and why the suit matters.

Texas Instruments Inc. v. Greenthread, LLC involved an Inter Partes Review (IPR) petition, IPR2024-00774, filed by petitioner Texas Instruments Inc. against patent owner Greenthread, LLC, concerning U.S. Patent No. 11,316,014. Texas Instruments Inc. is a multinational semiconductor company headquartered in Dallas, Texas, known for designing and manufacturing analog chips and embedded processors, and is a major player in the semiconductor industry. Greenthread, LLC, based in Texas, operates as a non-practicing entity (NPE), also known as a patent assertion entity (PAE), asserting semiconductor-related patents that it acquired, including those from inventor G.R. Mohan Rao. The IPR was terminated due to settlement on April 18, 2024, a week after its filing.

The IPR stemmed from an underlying patent infringement litigation, Greenthread, LLC v. Texas Instruments Inc., filed in the U.S. District Court for the Eastern District of Texas (Case No. 23-cv-00157, filed April 6, 2023). In this litigation, Greenthread accused Texas Instruments of infringing U.S. Patent No. 11,316,014, among other related patents in a family referred to as the "Greenthread Patents". These patents generally relate to semiconductor devices that incorporate graded dopants and well regions to create electric fields, which aid or limit the movement of charge carriers within the semiconductor material. The specific accused products or technology would be Texas Instruments' semiconductor devices that allegedly embody these features. The Eastern District of Texas is a well-known venue for patent litigation due to its reputation for a fast-paced docket and judges experienced in patent law.

This case is notable as it exemplifies a common pattern of NPEs like Greenthread, LLC asserting semiconductor patents against large operating companies in the tech industry. Greenthread has a history of asserting its portfolio against multiple major technology companies, including Intel, Dell, Samsung, Cirrus Logic, and Monolithic Power Systems, often leading to IPR challenges from the defendants. The early termination of this IPR due to settlement indicates a resolution between the parties, likely including the underlying district court litigation, consistent with how many NPE assertions conclude. This highlights the strategic interplay between district court infringement suits and parallel IPR proceedings in patent disputes involving NPEs.

Key Legal Developments and Outcome

The district court litigation between Greenthread, LLC and Texas Instruments Inc. was a short-lived case, marked by its swift resolution following the filing of a parallel proceeding at the Patent Trial and Appeal Board (PTAB). The case exemplifies a common strategy where the filing of an Inter Partes Review (IPR) acts as a catalyst for settlement.

Chronological Developments:

  • 2023-04-06: Complaint Filed
    Greenthread, LLC filed a patent infringement complaint against Texas Instruments Inc. in the U.S. District Court for the Eastern District of Texas (Case No. 2:23-cv-00157-JRG). The lawsuit alleged that Texas Instruments' semiconductor products infringed on a family of six patents, including U.S. Patent No. 11,316,014. The asserted patents generally relate to improved semiconductor device structures. This case was one of several similar lawsuits Greenthread filed around the same time against other major technology companies like OmniVision Technologies and OSRAM, which were all handled by Judge Rodney Gilstrap.

  • 2023-06-20: Answer and Counterclaims
    Texas Instruments filed its answer to the complaint, denying infringement and asserting that Greenthread's patents were invalid. Concurrently, Texas Instruments filed counterclaims seeking a declaratory judgment of non-infringement and invalidity of the asserted patents.

  • 2024-04-10: IPR Petition Filed
    In a move to challenge the validity of the asserted patent outside of the district court, Texas Instruments filed a petition for an Inter Partes Review (IPR) with the PTAB (Case No. IPR2024-00774). The petition challenged the patentability of claims in U.S. Patent No. 11,316,014, one of the key patents in the litigation.

  • 2024-04-18: Settlement and Termination of IPR
    Just eight days after the IPR was filed, the parties reached a settlement. A joint motion was filed at the PTAB requesting the termination of the IPR proceeding based on a settlement agreement. The PTAB granted the motion and terminated the IPR on the same day. This rapid sequence strongly suggests that the filing of the IPR petition prompted a swift business resolution between the parties. Under PTAB rules, parties must file their settlement agreement to terminate a proceeding.

  • Post-Settlement: Dismissal in District Court
    Following the IPR termination, the parties would have filed a joint stipulation of dismissal in the Eastern District of Texas case, bringing the patent infringement lawsuit to a close. While the exact date is not in the search results, this is the standard procedural step after a settlement is reached. The case did not advance to significant pretrial milestones such as a Markman claim construction hearing or trial.

Parallel Proceedings and Overall Context

The dispute between Greenthread and Texas Instruments did not occur in a vacuum. Greenthread, a non-practicing entity (NPE), has engaged in a broad litigation campaign, asserting its patent portfolio against numerous semiconductor companies, including Intel, Dell, Cirrus Logic, and Monolithic Power Systems. This broader context is relevant, as defendants in these parallel litigations also challenged Greenthread's patents at the PTAB. For example, in a separate set of IPRs (IPR2023-01242, -01243, -01244) involving Greenthread and another company, the PTAB's decisions on discovery and other procedural matters were subject to Director Review, indicating the high stakes and complexity of these related challenges.

The outcome of this case—a rapid settlement and dismissal following the filing of an IPR—is a textbook example of the strategic interplay between district court litigation and PTAB proceedings. For an accused infringer like Texas Instruments, an IPR offers a more specialized, and often faster, venue to argue patent invalidity. The filing of a meritorious IPR petition can significantly increase the patent owner's risk and litigation costs, thereby creating strong leverage for a favorable settlement. The quick resolution here indicates that Greenthread likely preferred to settle rather than face the possibility of the PTAB instituting a trial and potentially invalidating its patent claims.
