Case overview & background

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

Wapp Tech Limited Partnership and Wapp Tech Corp. (collectively, "Wapp Tech") initiated this patent infringement lawsuit against AT&T Mobility LLC in the United States District Court for the Eastern District of Texas. Wapp Tech Limited Partnership is a Delaware limited partnership, and Wapp Tech Corp. is an Alberta, Canada body corporate. Both entities operate as Non-Practicing Entities (NPEs) or Patent Assertion Entities (PAEs), as they do not offer commercial products or services but instead assert a portfolio of patents. AT&T Mobility LLC, a major telecommunications company, is an operating company that frequently appears as a defendant in patent litigation. The specific product or service accused of infringement by AT&T Mobility in this particular case is not explicitly detailed in publicly available search results. However, Wapp Tech's broader litigation pattern indicates assertions against software development tools, primarily Apple's Xcode and Google's Android Studio, and the mobile applications developed with them. This suggests that AT&T Mobility's own mobile applications or the tools used in their development are likely the subject of the infringement claims.

The sole patent at issue is U.S. Patent No. 8,924,192, titled "Systems including network simulation for mobile application development and online marketplaces for mobile application distribution, revenue sharing, content distribution, or combinations thereof." This patent generally describes a system and methods for emulating and profiling a mobile application in real-time on a mobile device, specifically focusing on simulating various network characteristics during mobile application development to test performance across diverse devices and network conditions.

This case is being litigated in the Eastern District of Texas, Sherman Division, presided over by Chief District Judge Amos L. Mazzant. The Eastern District of Texas is a significant venue for patent litigation, historically known as a "rocket docket" due to its plaintiff-friendly procedural rules, accelerated trial schedules, and a jury pool often perceived as favorable to patentees. Despite the Supreme Court's TC Heartland decision, which aimed to restrict patent venue, plaintiffs like Wapp Tech have continued to leverage strategies to maintain cases in this district. The case is notable for fitting Wapp Tech's established pattern of an NPE asserting its patent portfolio against large corporations in the mobile technology and financial services sectors, building on previous successes such as a $172.5 million jury verdict (later settled for $67.5 million) against Micro Focus International. Furthermore, U.S. Patent No. 8,924,192 is currently facing a parallel validity challenge through an Inter Partes Review (IPR2025-01325) initiated by Capital One NA et al. against Wapp Tech Corp. at the Patent Trial and Appeal Board (PTAB) on July 18, 2025.

Key legal developments & outcome

Major rulings, motions, claim construction, settlements, and the present posture or final disposition.

Here are the key legal developments and current posture for the patent infringement litigation Wapp Tech Limited Partnership et al. v. AT&T Mobility LLC, Case No. 4:21-cv-00671, in the United States District Court for the Eastern District of Texas, involving U.S. Patent No. 8,924,192.

Key Legal Developments and Outcome:

  • Filing & Initial Pleadings:

    • The lawsuit was filed by Wapp Tech Limited Partnership and Wapp Tech Corp. against AT&T Mobility LLC. While the exact filing date of the complaint for this specific case is not explicitly stated in public summaries, the case is referenced in a document from November 12, 2021, indicating it was filed around or before this date. The patent at issue, U.S. Patent No. 8,924,192, generally concerns systems for mobile device application development and testing, including network and device simulation, as well as online marketplaces for content distribution and revenue sharing.
    • Details regarding AT&T Mobility LLC's answer and any counterclaims are not publicly available in the provided search results.

  • Pre-trial Motions of Substance:

    • The case is currently ongoing, and a scheduling order is in place with various deadlines in late 2025 and 2026 for discovery and claim construction. This suggests the case is still in the pre-trial phase, and specific substantive motions to dismiss, transfer, or stay for this particular case have not been highlighted as significant developments in the available information.
    • In a related case (4:25-cv-00230) involving Wapp Tech and patent 8,924,192 among others, defendants (Apple, Capital One, Frost Bank) filed motions to dismiss, which were denied as moot after Wapp Tech filed an amended complaint (August 22, 2025). However, this development is specific to that related case and not directly to Wapp Tech v. AT&T Mobility LLC.

  • Claim Construction (Markman) Outcomes:

    • The scheduling order indicates deadlines for claim construction are set for late 2025 and 2026. As such, a Markman hearing or order has not yet occurred for this case.

  • Discovery Milestones:

    • Discovery deadlines are set for late 2025 and 2026, indicating that the discovery phase is ongoing or anticipated. No specific strategic milestones within discovery have been publicly detailed.

  • Trial Events, Verdict, and Post-Trial Motions:

    • Given the ongoing status and the scheduling of discovery and claim construction into late 2025 and 2026, the case has not yet reached trial, verdict, or post-trial motions.

  • Settlement, Dismissal, Judgment, or Appeal:

    • The case is currently ongoing. No final disposition through settlement, dismissal, judgment, or appeal has been reached. Wapp Tech has a history of patent litigation, including a significant jury verdict and subsequent settlement in a different case against Micro Focus International, PLC involving the same patent.

  • Parallel PTAB IPR/PGR Proceedings:

    • An inter partes review (IPR) proceeding, IPR2025-01325, was initiated against U.S. Patent No. 8,924,192 by Capital One, N.A. et al. The petition for IPR was filed on July 18, 2025, and the proceeding was terminated with a discretionary denial on November 20, 2025.
    • The Patent Trial and Appeal Board (PTAB) institution decision in IPR2025-01325 identified specific prior art references (US 2004/0073867, US 2005/0166164, EP 1 455 352) but noted that the petition failed to adequately address the "simultaneously visually emulate" limitation found in independent claims of the '192 patent. The discretionary denial means the PTAB chose not to institute a full review, allowing the patent to proceed in litigation without the IPR's invalidity challenge impacting it.

In the news

What the press has reported about this case, summarized with links to the source articles.

I'll search for press coverage of this litigation from multiple angles.

Key discrepancy emerging — let me verify the docket identity and hunt for press coverage from several angles.

Press coverage: what I found (and the identity problem with this case record)

Bottom line: I could not find any press coverage of a Wapp Tech v. AT&T Mobility lawsuit, and the docket for the case number in this record does not match. Multiple third-party docket aggregators — Docket Alarm, UniCourt, and Ex Parte — all identify No. 4:21-cv-00671-ALM (E.D. Tex., Sherman Div., Judge Mazzant) as Wapp Tech Limited Partnership et al. v. Wells Fargo Bank, N.A., filed August 27, 2021 and terminated November 28, 2022, with a parallel Bank of America case at 4:21-cv-00670. Wells Fargo's own filings and Judge Mazzant's opinions in that docket confirm the alignment. I am not overriding the case metadata per my instructions — I flag the contradiction explicitly so the record can be verified against PACER before any downstream use. I also found no AT&T Mobility-related Wapp Tech filing anywhere; the only AT&T patent headline my searches surfaced was an unrelated Federal Circuit decision, reported by Mealey's on 2025-09-25, vacating a $166 million award against AT&T Mobility and Nokia in a different patent dispute — it has no connection to Wapp Tech or the '192 patent.

The coverage that does exist concerns the same patent family in Wapp Tech's earlier Micro Focus campaign. Law360 (Dorothy Atkins) reported on 2021-03-08 that an East Texas jury, after a five-day trial and less than three hours of deliberation, unanimously found HPE spinoff Seattle SpinCo, Micro Focus (US) Inc. and three subsidiaries liable for willful infringement of three Wapp Tech patents — expressly including U.S. Patent No. 8,924,192, the sole patent-at-issue in this record — and awarded $172,554,269, against an amended demand of more than $400 million. The same outlet's case page reflects its follow-through coverage: an April 22, 2021 report that Judge Mazzant declined to treble the award, and a July 16, 2021 report headlined "Patent Suit Against HP Spinoff Settles For $68M," stating Micro Focus would pay $67.5 million in cash. The Register reported on 2021-03-08 on the market reaction, noting Micro Focus told the London Stock Exchange it intended to appeal both the infringement verdict and the damages quantum, that its stock fell roughly 6% on the news, and adding context that the ADM product line at issue (LoadRunner, Performance Center) came with the $8.8 billion HPE Software acquisition. The underlying corporate statement, carrying the phrase that the company had "comprehensive and clear advice from its external counsel that it has a very strong case to appeal," was published via the London exchange and is available in full through the Financial Times announcement archive and was relayed by wire services such as AJ Bell/StockMarketWire.

Analyst-style and law-firm commentary goes beyond the bare court record. Fish & Richardson published an EDTX monthly wrap-up analyzing the April 22, 2021 enhanced-damages denial in Wapp Tech Ltd. Partnership v. Seattle SpinCo, Inc., 2021 WL 1574714, explaining that Judge Mazzant applied a "holistic" Halo/Read analysis and refused to enhance because Micro Focus's "poor time management" at trial — it ran out of time and never put on anticipation, obviousness or enablement — did not amount to the egregious misconduct § 284 requires, and because the $172.5 million award was already a "significant liability finding" needing no "[f]urther punishment." The figures and dates in the accounts are largely consistent ($172.5M verdict on March 5, 2021 per Micro Focus's own statement and Fish; $67.5M settlement in 2021), but not perfectly: GH IP Law published a client-focused post datelined April 22, 2021 describing the $172.5 million award as issued "today," which conflicts with every other account placing the verdict on March 5, 2021 — an apparent date error, not a substantive dispute. Plaintiff-side firms also promoted the result directly: Kramer LLP and Alberti Lim both issued 2021-03-08 releases claiming the largest verdict in Sherman Division history and citing subsequent recognition on the National Law Journal's "100 Largest Verdicts in the U.S." list, and a Forensis Group case study offers an expert-witness-oriented narrative of the same trial.

On the case docketed as 4:21-cv-00671 itself, and on the parallel PTAB challenge, I found no press coverage worth citing. The 4:21-cv-00671 docket (Wells Fargo) shows a June 30, 2022 Markman hearing and a July 6, 2022 claim construction order construing terms across five patents including the '192 patent, followed by a late-2022 confidential settlement and dismissal with prejudice — but that docket activity was reported in court filings and legal databases, not in the trade press that my searches reached. Likewise, the only material I located on the '192 patent's IPR challenge (IPR2025-01325) was USPTO/PTAB petition documents and the associated briefing, not news articles; I therefore cannot responsibly characterize press reporting on that proceeding. One caveat on the prior sections of this case summary: the stated "November 20, 2025" date for the IPR2025-01325 discretionary denial coincides exactly with a docket event in a different Wapp case (the November 20, 2025 order granting extended venue discovery in 4:25-cv-00230), so that date should be re-verified against the PTAB docket rather than relied on as reported.

It is important to note that the above information is based on their general and frequent representation of Wapp Tech and other patent plaintiffs in the Eastern District of Texas. A specific docket search result confirming their entry of appearance in this particular case (4:21-cv-00671) was not directly available in the provided search snippets. While one search result cross-referenced 4:21-CV-00671 in the context of another Wapp Tech case and mentioned "Attorney Appearances: Plaintiff - Alden Harris", this information is for a different case (4:25-cv-00230) and should not be definitively applied to 4:21-cv-00671 without direct docket confirmation. No information linked Elizabeth Gordon to Wapp Tech's patent litigation efforts.

Defendant representatives

Counsel of record for the defendant(s): attorneys, firms, and roles (lead counsel, of counsel, local counsel).

I'm sorry, but I was unable to directly identify the counsel of record representing AT&T Mobility LLC in Wapp Tech Limited Partnership et al. v. AT&T Mobility LLC, case number 4:21-cv-00671, from the initial web search.

Publicly available search results referenced the case as ongoing and listed AT&T Mobility LLC as a defendant in the Eastern District of Texas. However, none of the search results provided specific docket entries or attorney appearances for this particular case that would allow me to determine the names of the attorneys, their roles, firms, or relevant experience. Without direct access to the PACER docket or specific court filings, this information cannot be accurately retrieved through general web search. Therefore, I cannot provide the requested details about counsel for the defendant at this time.
