Case Overview and Background: Avant Location Technologies LLC v. Apple Inc. (N.D. Tex. 3:25-cv-02642)

This patent infringement litigation, though voluntarily dismissed in the Northern District of Texas, represents a segment of a broader campaign by Avant Location Technologies LLC (Avant) against Apple Inc., primarily centered on technology related to monitoring mobile station presence. Avant Location Technologies LLC is identified as a Non-Practicing Entity (NPE) and an entity of Anjay Venture Partners LLC, indicating its business model likely revolves around asserting patent rights rather than producing goods or services. Conversely, Apple Inc. is a global operating company renowned for its consumer electronics, software, and online services, including iconic products like the iPhone, iPad, and Apple Watch. The accused products in this campaign are Apple devices that implement the "Find My" feature, which allows users to locate lost devices.

The primary patent at issue in this campaign, U.S. Patent 8,738,040, generally relates to methods for monitoring the presence of a mobile station. Avant had initially filed a complaint against Apple in the Eastern District of Texas (2:24-cv-00757-JRG) asserting this and six other patents. This initial Eastern District case was subsequently transferred, and Avant then refiled a case against Apple (3:25-cv-02642-X) in the Northern District of Texas. However, Avant voluntarily dismissed the Northern District of Texas case without prejudice on October 1, 2025. Within hours of this dismissal, Avant filed a new complaint asserting the same seven patents against Apple in the Western District of Texas (7:25-cv-00445-ADA), where the litigation is currently active. The specific judge for the dismissed Northern District of Texas case (3:25-cv-02642-X) could not be definitively identified through web search.

This litigation is notable due to Avant's strategy of repeatedly filing and refiling in different Texas districts, a common tactic employed by NPEs in the wake of the TC Heartland Supreme Court decision, which significantly altered patent venue rules. While the Eastern District of Texas was historically a major hub for patent litigation, TC Heartland limited venue primarily to where a defendant is incorporated or has a regular and established place of business. This led to a shift in filings, with the Northern and Western Districts of Texas seeing increased patent litigation activity, particularly from NPEs. Apple has also responded to Avant's assertions by filing petitions for inter partes review (IPR) challenging the patentability of all asserted claims, including those of U.S. Patent 8,738,040. These IPR proceedings are potentially case-dispositive and are expected to be decided before any trial in the Western District of Texas case. This interplay between district court litigation and parallel PTAB IPRs is a significant aspect of contemporary patent disputes.

The patent infringement litigation, Case No. 3:25-cv-02642, filed in the U.S. District Court for the Northern District of Texas, was part of a broader, multi-district litigation campaign by Avant Location Technologies LLC against Apple Inc. The case itself saw an early voluntary dismissal by Avant, redirecting the dispute to the Western District of Texas.

Chronological Legal Developments:

2024-09-13: Initial Complaint Filed (Eastern District of Texas)
Avant Location Technologies LLC first initiated litigation against Apple Inc. by filing a complaint in the U.S. District Court for the Eastern District of Texas, Case No. 2:24-cv-00757-JRG. This complaint asserted infringement of U.S. Patent No. 8,738,040, along with six other patents.

2024-11-22: Apple's Motion to Dismiss or Transfer (Eastern District of Texas)
Apple responded to the Eastern District of Texas complaint by filing a motion to dismiss for improper venue or, alternatively, to transfer the case to the Northern District of California.

Early-to-Mid September 2025: Apple Files IPR Petitions
Prior to Avant's filing of the instant case in the Northern District of Texas (and the subsequent Western District of Texas case), Apple filed multiple petitions for inter partes review (IPR) with the Patent Trial and Appeal Board (PTAB). These IPRs challenged the patentability of all asserted claims across all seven patents-in-suit, including U.S. Patent No. 8,738,040. Examples include IPR2025-01257 and IPR2025-01259.

2025-09-29: Case Transferred to Northern District of Texas
The Eastern District of Texas court granted Apple's motion to dismiss for improper venue and transferred Case No. 2:24-cv-00757-JRG to the U.S. District Court for the Northern District of Texas. Upon transfer, it was assigned Case No. 3:25-cv-02642-X.

2025-10-01: Voluntary Dismissal Without Prejudice (Northern District of Texas)
Within hours of the transfer to the Northern District of Texas, Avant Location Technologies LLC voluntarily dismissed Case No. 3:25-cv-02642-X without prejudice. The docket entry for this dismissal is Dkt. 97, Notice of Voluntary Dismissal Without Prejudice.

2025-10-01: New Complaint Filed (Western District of Texas)
Immediately following the dismissal of the Northern District of Texas case, Avant filed a new complaint asserting the same seven patents against Apple in the U.S. District Court for the Western District of Texas, Case No. 7:25-cv-00445-ADA.

Outcome:

The Northern District of Texas case (3:25-cv-02642) was voluntarily dismissed without prejudice by Avant Location Technologies LLC on October 1, 2025. This dismissal effectively concluded the proceedings in the Northern District of Texas. The litigation campaign, however, continued with Avant's immediate refiling of the same claims against Apple in the Western District of Texas.

Effect of Parallel PTAB IPR Proceedings:

While the Northern District of Texas case was swiftly dismissed, the parallel IPR proceedings remain a significant factor in the broader litigation against Apple. Apple's IPR petitions, filed before the Western District of Texas case, challenged all asserted claims of the patents-in-suit, including U.S. Patent No. 8,738,040. These IPRs are considered potentially case-dispositive, and the Patent Trial and Appeal Board is expected to issue final written decisions by March 2027. Apple has also stipulated that, if the IPRs are instituted, it will be estopped from asserting certain prior art theories in the related district court litigation. The existence and progress of these IPRs heavily influenced Apple's subsequent motion to stay the newly filed Western District of Texas case.

The plaintiff, Avant Location Technologies LLC, was represented by a team of attorneys in the voluntarily dismissed Northern District of Texas case (3:25-cv-02642). While comprehensive docket information for this specific dismissed case is not readily available through public web search, details from related Avant Location Technologies LLC litigation against Apple Inc., particularly the ongoing Western District of Texas case (7:25-cv-00445-ADA) and the initial Eastern District of Texas case (2:24-cv-00757-JRG), provide insight into their typical counsel.

Based on these related filings and general practices for patent assertion entities, the following attorneys are likely to have been involved, or are representative of the type of counsel Avant Location Technologies LLC retains:

• Michael F. Heim

  • Role: Lead Counsel.
  • Firm: Heim, Payne & Chorush LLP (Houston, TX).
  • Note: Mr. Heim is a founding partner and managing director of Heim, Payne & Chorush, specializing exclusively in intellectual property litigation and antitrust lawsuits involving intellectual property.

He has been recognized as Houston's Lawyer of the Year for patent and intellectual property infringement trials.

• Scott W. Weatherford

  • Role: Local Counsel (likely, given his practice in Texas).
  • Firm: Jackson Walker (Austin, TX).
  • Note: Mr. Weatherford is an innovative trial attorney focusing on intellectual property, trade secret, and technology-related commercial disputes. He advocates for various clients in state and federal courts across Texas and has been admitted to practice before all Texas federal district courts.

He is admitted to practice in the U.S. District Courts for the Eastern, Northern, and Western Districts of Texas, and has experience with cases involving a failed $1 billion contract with Apple Inc.

It is important to note that while the Northern District of Texas case was dismissed, these attorneys or attorneys with similar profiles at these firms frequently represent patent owners like Avant Location Technologies LLC in Texas district court litigation and related PTAB proceedings. For instance, Peter Lambrianakos of Fabricant LLP is listed as lead counsel for Avant Location Technologies LLC in related IPR proceedings challenging U.S. Patent No. 9,119,030.

The case 3:25-cv-02642 in the Northern District of Texas was voluntarily dismissed by Avant Location Technologies LLC on October 1, 2025. While specific counsel information for this dismissed N.D. Texas case is not readily available through general web searches, Apple Inc. typically retains experienced legal teams for its patent litigation.

Based on publicly available information regarding Apple's patent litigation practices and general in-house counsel roles, the following types of counsel would likely be involved for Apple in such a case:

In-House Counsel (Apple Inc.)

• Role: Lead strategists, overseeing all aspects of the litigation, and often working closely with outside counsel.
• Notable individuals at Apple in IP Litigation roles:
  • Iain Cunningham: Senior Litigation Counsel at Apple, with experience in high-profile patent litigation.
  • Jeff Myers: Chief IP Counsel at Apple, also serving as Senior Director of the intellectual property & licensing team.
  • Other Principal Legal Counsel - IP Litigation: Apple actively recruits highly experienced patent litigators to drive litigation strategy and manage complex, high-stakes patent disputes.

Given the voluntary dismissal of the N.D. Texas case and the subsequent refiling in the W.D. Texas (7:25-cv-00445-ADA), it is probable that the same or a very similar team of attorneys, both in-house and external, would continue to represent Apple in the ongoing litigation. For the ongoing Western District of Texas case, court filings such as motions and certificates of service would typically list the specific attorneys of record.

Without direct access to the docket for 3:25-cv-02642 prior to its dismissal, identifying specific outside counsel who made an appearance is not possible through public web search. However, major technology companies like Apple frequently engage prominent intellectual property law firms for their litigation needs.
