Wapp Tech Limited Partnership et al. v. Bank of America Corporation

This patent infringement litigation, Wapp Tech Limited Partnership et al. v. Bank of America Corporation, involves plaintiff patent assertion entities Wapp Tech Limited Partnership and Wapp Tech Corp. (collectively, "Wapp Tech") and defendant Bank of America Corporation, a major financial institution. Wapp Tech, characterized as a Non-Practicing Entity (NPE), asserts patents related to mobile application development and testing technology. Bank of America is accused of infringing by utilizing third-party software products, specifically Micro Focus (formerly Hewlett Packard Enterprise) testing systems such as LoadRunner and Performance Center, to develop and test its mobile banking applications. The primary patent at issue in this case is U.S. Patent No. 8,924,192, titled "System for developing an application for a mobile device," which generally describes a system with a software authoring interface designed to visually emulate various network characteristics and connection states to simulate mobile device performance during application execution.

The case is being litigated in the United States District Court for the Eastern District of Texas, Sherman Division, presided over by Chief District Judge Amos L. Mazzant. This venue is historically significant for patent litigation, often referred to as a "rocket docket" due to its plaintiff-friendly reputation, expedited schedules, and specialized local rules, although the Supreme Court's TC Heartland decision in 2017 impacted venue rules. The litigation is notable as part of a broader assertion campaign by Wapp Tech against various companies in the mobile technology ecosystem, including other major banks (Wells Fargo, JPMorgan Chase, Capital One, Apple) and software manufacturers.

A key procedural aspect in this case is Bank of America's motion to stay proceedings, invoked under the "customer suit doctrine." This doctrine allows a customer-defendant, such as Bank of America, to request a stay of litigation when the manufacturer of the allegedly infringing product (in this instance, Micro Focus/Hewlett Packard Enterprise) is also being sued for infringement of the same patents. Wapp Tech has demonstrated success in this campaign, securing a $172.5 million jury verdict against Micro Focus International, which subsequently settled for $67.5 million, and also reaching a settlement with Wells Fargo. This extensive litigation history underscores Wapp Tech's aggressive enforcement strategy in the critical and rapidly expanding mobile application development market.

Key Legal Developments and Outcome in Wapp Tech Limited Partnership et al. v. Bank of America Corporation

This patent infringement litigation, Case No. 4:18-cv-00519-ALM-KPJ, filed in the U.S. District Court for the Eastern District of Texas, has seen significant developments, including a substantial jury verdict. The case is currently ongoing.

Filing & Initial Pleadings

• Complaint Filed: Wapp Tech Limited Partnership and Wapp Tech Corp. (collectively, "Wapp Tech") initiated the lawsuit on October 15, 2018, alleging infringement of U.S. Patent 8,924,192.
• Answer and Counterclaims: Bank of America Corporation filed its answer on October 16, 2018, denying infringement and asserting affirmative defenses, including invalidity of the asserted patent claims.

Pre-Trial Motions of Substance

• Motion to Stay: On October 17, 2018, Bank of America filed a motion to stay the proceedings. The motion invoked the "customer suit doctrine," arguing that the case should be stayed pending the final resolution of parallel litigation against "manufacturer cases," specifically identifying Micro Focus International plc, Seattle SpinCo, Inc., and EntIT Software LLC as the true defendants. The motion to stay was ultimately denied, allowing the case to proceed to trial.
• Claim Construction (Markman) Outcome: A consolidated Claim Construction Memorandum Opinion and Order (Markman order) was issued on April 27, 2020, by District Judge Amos L. Mazzant, III. This order applied to Wapp Tech's cases against Bank of America, Wells Fargo & Co., and Seattle SpinCo, Inc., et al., establishing the judicial construction for the disputed terms of the patents-in-suit.

Discovery Milestones

Specific strategic discovery milestones are not publicly detailed in the available information.

Trial Events, Verdict, and Post-Trial Motions

• Jury Verdict: The consolidated cases, including Wapp Tech's suit against Bank of America, proceeded to a jury trial. The jury found the defendants liable for infringement of Wapp Tech's patents and awarded $172 million in damages. The exact date of this verdict is not specified in the provided sources, but it occurred after the April 2020 Markman order.
• Post-Trial Motions: Given the significant jury verdict, post-trial motions such as motions for judgment as a matter of law (JMOL) or for a new trial are highly probable, though specific rulings on such motions are not detailed in the provided search results.

Settlement, Dismissal, Judgment, or Appeal

• The case is listed as "Ongoing" in the initial prompt. While a jury verdict has been rendered, the "ongoing" status likely indicates that post-trial proceedings, such as appeals or further motions regarding the judgment, are still underway. The sources do not provide a final disposition or settlement details for the Bank of America case specifically, beyond the jury verdict. One source mentions that a separate case by Wapp Tech against Micro Focus produced a $172M jury verdict and ultimately a $67.5M settlement, suggesting that the $172M verdict might have been against the manufacturer in a related case (4:18-cv-00469) rather than Bank of America directly, or that the Bank of America case was part of this larger outcome. However, the consolidated case number in and suggests Bank of America was part of the case that yielded the $172M verdict.

Parallel PTAB IPR/PGR Proceedings

• IPR2025-01325: Capital One NA and others filed an Inter Partes Review (IPR) against U.S. Patent 8,924,192 (IPR2025-01325) on July 18, 2025. This IPR was terminated on November 20, 2025. Although the specific reason for termination is not explicitly stated, the notation "Institution: 11/20/2025" alongside "Terminated: 11/20/2025" strongly suggests that the petition for IPR was denied institution by the Patent Trial and Appeal Board (PTAB) on that date. There is no information about any earlier IPRs on the '192 patent that would have predated or significantly impacted the district court proceedings leading to the 2020 Markman order and subsequent jury verdict.
