American Patents v. Texas Instruments: Consent Judgment in MIMO Patent Dispute
American Patents LLC asserted three MIMO wireless technology patents against Texas Instruments in the Eastern District of Texas, targeting channel estimation and time-frequency synchronization systems. The case resolved by consent judgment after 350 days, with both parties bearing their own costs and the court retaining jurisdiction to enforce the settlement agreement.
Three MIMO Patents, One Consent Judgment: How the Case Resolved
American Patents LLC filed suit against Texas Instruments, Incorporated on June 6, 2022 in the Eastern District of Texas (Case No. 4:22-cv-00480), asserting infringement of three patents — US7706458B2, US7310304B2, and US7088782B2 — covering multi-input, multi-output (MIMO) wireless technologies, specifically channel parameter estimation and time-and-frequency synchronization in MIMO systems. Texas Instruments, a major semiconductor and signal-processing company, was the sole defendant.
The recorded basis of termination is Consent Judgment. The docket order — entered pursuant to a Joint Motion to Dismiss under Rule 41 of the Federal Rules of Civil Procedure — directed that all claims and counterclaims by both parties are dismissed with prejudice, while the court expressly reserved jurisdiction over both parties to enforce the settlement agreement between American Patents and Texas Instruments. Each party was ordered to bear its own costs, expenses, and legal fees.
The case closed on May 22, 2023, approximately 350 days after filing — a resolution timeline consistent with pre-trial settlement in the Eastern District of Texas, which is known for its active patent docket. The existence of an underlying settlement agreement is confirmed by the court's retention of enforcement jurisdiction, though the specific terms of that agreement are not disclosed in the available public record.

US7706458B2, US7310304B2 & US7088782B2 — MIMO Wireless Technology Patents
Any company designing, manufacturing, or integrating MIMO-capable chipsets, Wi-Fi modules, or cellular modems should assess exposure to this three-patent family. The asserted technologies — channel parameter estimation and time-frequency synchronization in MIMO systems — are architectural requirements in 802.11n/ac/ax and LTE/5G implementations. Consent judgment outcomes with retained court jurisdiction suggest the patents are enforceable and commercially active.
Official order — verbatim text
The court's order, entered on a Joint Motion to Dismiss, dismisses all claims and counterclaims with prejudice under Rule 41 and explicitly reserves jurisdiction to enforce the parties' settlement agreement. The with-prejudice dismissal bars re-filing of the same MIMO patent claims against Texas Instruments. The retained enforcement jurisdiction confirms the existence of a binding settlement agreement, though its specific terms are not disclosed in the public record.
Consent judgment: what the agreed resolution means for both parties
What a consent judgment means in patent litigation
A consent judgment is a binding, court-entered judgment on terms agreed by both parties, formally ending the litigation. Here, the court entered the order on a Joint Motion to Dismiss, dismissing all claims and counterclaims with prejudice. Critically, the court expressly retained jurisdiction to enforce the settlement agreement between American Patents and Texas Instruments — meaning neither party can simply walk away from agreed obligations.
Court-entered, binding, finalAmerican Patents: litigation closed, settlement agreement enforceable
For American Patents LLC, the consent judgment brings the infringement action to a conclusion with the court retaining jurisdiction to enforce the settlement agreement. The dismissal is with prejudice, meaning American Patents cannot re-file the same claims against Texas Instruments on these three MIMO patents. The specific commercial terms of the settlement are not disclosed in the available public record.
Claims dismissed with prejudiceTexas Instruments: counterclaims also dismissed, own costs apply
Texas Instruments' counterclaims are equally dismissed with prejudice under the consent judgment. TI bears its own legal costs and fees, consistent with the mutual cost-bearing provision in the order. The retained court jurisdiction to enforce the settlement agreement applies symmetrically to both parties. No further details about TI's obligations under the settlement are disclosed in the available public record.
Counterclaims dismissed with prejudiceMIMO patent enforcement: what this signals for the wireless sector
American Patents' pursuit of a major semiconductor company over MIMO channel estimation and synchronization patents — core technologies in Wi-Fi and cellular systems — suggests continued assertion risk in this domain. The consent judgment with retained enforcement jurisdiction is consistent with a structured resolution. Companies operating in MIMO wireless technology should monitor the American Patents portfolio for further enforcement activity against comparable implementations.
