Trackthings v. Amazon & Eero: Wi-Fi Patent Suit Ends on Standing
Trackthings, LLC asserted three wireless networking patents against Amazon’s eero mesh Wi-Fi product line and Ring Alarm Pro Base Station. Before any merits ruling, Judge Alan Albright dismissed all claims with prejudice — finding Trackthings lacked standing to bring suit — after 1,549 days of litigation.
A threshold standing defect kills a multi-patent Wi-Fi mesh suit
Trackthings, LLC filed Case No. 6:21-cv-00720 in the Western District of Texas on July 13, 2021, asserting infringement of three U.S. patents — US9332442B2, US9642017B2, and US10107893B2 — against Amazon.com Inc., Amazon.com Services LLC, and Eero LLC. The accused products spanned Amazon’s eero mesh Wi-Fi ecosystem (multiple generations) and the Ring Alarm Pro Base Station, representing a core segment of Amazon’s smart home and home networking hardware portfolio.
The case never reached a merits ruling. Amazon and Eero moved to dismiss for lack of standing, and on February 17, 2023, Judge Alan Albright granted the motion by oral order. The subsequent written order, consistent with that ruling, dismissed all of Trackthings’ claims with prejudice — meaning they cannot be refiled — while Amazon’s counterclaims and defenses were dismissed without prejudice, leaving defendants free to reassert those positions in any future proceeding.
Despite the case running for over four years from filing to final closure on October 9, 2025, the substantive litigation timeline on standing was resolved relatively early. The public record does not reveal the specific ownership or assignment defect the court identified, nor whether Trackthings pursued or could pursue a cure through re-assignment. The with-prejudice dismissal of plaintiff’s claims suggests the court found the standing defect was not curable — a significant outcome for the asserted patent portfolio.

Dismissed with prejudice for lack of standing: what the ruling means
Standing dismissed with prejudice — no merits ever reached
Article III standing requires a plaintiff to hold enforceable rights in a patent at the time of filing. A motion to dismiss for lack of standing is a threshold challenge — if granted, no infringement analysis occurs. Here, the court dismissed all of Trackthings’ claims with prejudice under this doctrine, meaning the court found the standing defect incurable rather than merely premature, barring any refiling of the same claims.
Threshold procedural dismissalWith-prejudice bar forecloses Trackthings from reasserting these claims
A with-prejudice dismissal is the most adverse procedural outcome short of a merits loss. Trackthings cannot refile the same infringement claims against Amazon and Eero based on these three patents. The public record does not clarify whether the standing defect stemmed from an assignment gap, co-ownership issue, or another chain-of-title problem — but the with-prejudice nature of the ruling suggests the court found no path to cure.
Claims permanently barredAmazon and Eero walk away with counterclaims intact for future use
Amazon’s counterclaims and defenses — which likely included invalidity and non-infringement positions — were dismissed without prejudice. This preserves Amazon’s ability to reassert those positions if Trackthings or any successor entity ever attempts to enforce the same patents. Amazon achieves a clean exit on the current action while retaining its defensive arsenal.
Defendant defenses preservedeero and Ring product lines face no injunction risk from this action
The with-prejudice dismissal means Amazon’s eero mesh Wi-Fi lineup and Ring Alarm Pro products face no ongoing injunction or damages exposure from Trackthings under these three patents in this action. However, the patents themselves may still be enforceable by a party with clean standing. Companies operating in the mesh networking and smart home connectivity space should monitor ownership of these patents for future enforcement risk.

Official order — verbatim text
The court’s order tracks a two-stage resolution: an oral ruling granting the motion on February 17, 2023, followed by a written order formalising the outcome. The with-prejudice dismissal of plaintiff’s claims is the operative consequence — it forecloses refiling under res judicata principles. The without-prejudice dismissal of defendant counterclaims preserves Amazon’s legal positions entirely. Critically, no merits analysis of the three asserted patents was conducted, meaning claim scope, validity, and infringement remain legally unresolved for any future proceeding by a party with proper standing.
US9332442B2, US9642017B2 & US10107893B2 — wireless networking & device tracking
The three asserted patents — US9332442B2 (App. No. 14/093541), US9642017B2 (App. No. 11/681158), and US10107893B2 (App. No. 13/198748) — cover technologies in the wireless networking, device identification, and location-tracking domain. The span of application numbers across three separate prosecution chains suggests a portfolio built over multiple years, potentially covering foundational approaches to tracking and managing devices across wireless networks — technology directly relevant to mesh Wi-Fi architectures and connected home systems.
The selection of eero’s full product family — from first-generation hardware through eero Pro 6E — as accused products suggests Trackthings believed the core network management or device-tracking functionality was embedded across the entire eero architecture, not just a single SKU. This breadth of accused products is consistent with patents directed at protocol-level or firmware-level functionality rather than specific hardware implementations. The patents were never adjudicated on the merits, meaning their claim scope and validity remain untested in litigation.
Should your team run an FTO against US9332442B2, US9642017B2, and US10107893B2?
Any company developing or commercialising mesh Wi-Fi systems, smart home networking hardware, or IoT device management platforms should treat these three patents as live enforcement risks. The with-prejudice dismissal eliminated Trackthings as the enforcing party in this action — but it did not invalidate or limit the patents. A successor acquirer with clean standing could assert them. R&D and product teams building wireless device tracking, network-layer device identification, or distributed home networking systems are most exposed.
PatSnap Eureka’s FTO Search Agent can map the claim language of US9332442B2, US9642017B2, and US10107893B2 against your product architecture, surface relevant prior art that could support an invalidity argument, and monitor for ownership transfers that might signal renewed enforcement activity. Given the unresolved merits status of these patents, a proactive FTO review is a lower-cost insurance policy than reactive litigation defence.

What this case signals for the mesh networking IP landscape
A four-year, three-patent assertion against Amazon collapses at the standing gate — highlighting a critical pre-filing risk for PAEs and licensors.
Standing diligence is as critical as claim chart quality before filing
Trackthings secured four years of litigation before the standing defect proved fatal. Any entity asserting patents — especially those acquired through assignment chains — must confirm exclusive standing at the precise moment of filing. A chain-of-title audit is not optional; it is the first line of a viable enforcement strategy.
With-prejudice dismissal signals the patents may still have enforcement value for others
The dismissal was procedural, not substantive. The claims of US9332442B2, US9642017B2, and US10107893B2 were never adjudicated on the merits. Any party who acquires clean title to these patents may retain the ability to assert them — making ongoing ownership monitoring relevant for mesh Wi-Fi and smart home network competitors.
Trackthings v Amazon.com — key questions answered
The court granted Amazon’s Motion to Dismiss for Lack of Standing, finding that Trackthings did not hold the requisite enforceable interest in the asserted patents at the time of filing. The dismissal was with prejudice as to Trackthings’ claims, meaning they cannot be refiled. The specific assignment or chain-of-title defect is not detailed in the public order.
The patents themselves were not invalidated — no merits ruling was issued. They remain potentially enforceable by any party that can establish proper ownership and standing. The with-prejudice dismissal bars Trackthings specifically, but a subsequent owner with clean title could potentially assert the same patents against the same or different defendants.
Amazon’s counterclaims and defenses — likely including invalidity and non-infringement arguments — were dismissed without prejudice. This means Amazon did not waive those positions and may reassert them in any future proceeding involving the same patents, preserving full defensive optionality if enforcement is attempted again.
No. The case was dismissed on standing grounds before any infringement analysis. No court has determined whether the eero product family or Ring Alarm Pro Base Station infringes any of the three asserted patents. The accused products face no injunction or damages liability arising from this specific action.
Yes. Judge Albright’s Western District of Texas court is frequently associated with plaintiff-friendly patent litigation outcomes. A threshold standing dismissal with prejudice against a patent asserting entity in this court is relatively notable and suggests that even in WDTX, threshold defects in plaintiff ownership will be enforced — consistent with Federal Circuit doctrine on Article III standing requirements.
