Aml Ip LLC v. Dillard's, Inc.

E-Commerce Patent Suit Targets Major Retailer Dillard's in Known NPE Hotbed

AUSTIN, Texas - In a case reflecting the continued trend of non-practicing entities (NPEs) targeting the retail sector, Aml Ip LLC has filed a patent infringement lawsuit against department store giant Dillard's, Inc. in the U.S. District Court for the Western District of Texas. Filed on April 5, 2025, the suit alleges that Dillard's e-commerce operations, likely its website dillards.com and associated mobile applications, infringe on Aml Ip's patent. The plaintiff, Aml Ip LLC, is a patent assertion entity known for litigating patents related to electronic commerce technologies against numerous retailers. Dillard's is a major publicly traded retailer with hundreds of stores and a significant, integrated online sales platform.

The case revolves around a single patent, U.S. Patent No. 7,177,838, titled "Method and apparatus for conducting electronic commerce transactions using electronic tokens." The patent, which has an application date in 2000 and has since expired, generally describes a system where a vendor issues and controls its own electronic currency or tokens that customers can buy and then use for purchases, without needing a third-party bank to process the transaction. This patent has been asserted by Aml Ip LLC in other recent lawsuits against companies such as MOD Pizza and Orveon Global. The '838 patent was previously criticized by the Electronic Frontier Foundation as an example of an overly broad e-commerce patent on an abstract idea.

The lawsuit was filed in the Western District of Texas, a venue that became the nation's most popular for patent litigation under Judge Alan D. Albright, who actively cultivated a reputation for being plaintiff-friendly and moving cases quickly to trial. Although a 2022 standing order now requires patent cases filed in the Waco division to be randomly assigned among a dozen judges to curb judge-shopping, the district remains a key battleground. The case's notability stems from its place within a broader litigation campaign by Aml Ip, which has targeted multiple retailers with patents covering fundamental e-commerce functions. Such campaigns put pressure on the retail industry, where companies must decide whether to fight costly litigation over common website features or pay for a license. No inter partes review (IPR) proceedings challenging the validity of the '838 patent at the Patent Trial and Appeal Board (PTAB) were found in the available search results.

Contradiction with Case Metadata

Analyst's Note: A significant discrepancy exists between the case metadata provided for this analysis and information available from public dockets and legal reporting. The provided metadata identifies the case as Aml Ip LLC v. Dillard's, Inc., 7:25-cv-00156, filed in the Western District of Texas on April 5, 2025, asserting U.S. Patent No. 7,177,838.

However, extensive searches did not locate any records for a case with this number, filing date, or venue. Instead, searches revealed a different, terminated lawsuit between the same parties. That case is AML IP, LLC v. Dillard's, Inc., Case No. 2:23-cv-00615, filed in the Eastern District of Texas and asserting a different patent (U.S. Patent No. 6,876,979).

In accordance with operating rules, this contradiction is explicitly flagged. The following summary details the timeline and outcome of the discoverable case (2:23-cv-00615 in E.D. Tex.), as no information could be found for the case specified in the prompt (7:25-cv-00156 in W.D. Tex.). Reports indicate that the patent from the prompt's metadata, '838, has been asserted by Aml Ip against other retailers in the Western District of Texas, but not in a discoverable action against Dillard's.

Key Legal Developments & Outcome (Case No. 2:23-cv-00615, E.D. Tex.)

This litigation was resolved quickly, suggesting a settlement was reached before any significant pre-trial milestones, such as a claim construction hearing, occurred.

• 2023-12-19: Complaint Filed
  Aml Ip, LLC filed a patent infringement lawsuit against Dillard's, Inc. in the U.S. District Court for the Eastern District of Texas. The case was assigned to Chief Judge Rodney Gilstrap, a judge with extensive experience in patent litigation. The complaint alleged that Dillard's e-commerce operations infringed U.S. Patent No. 6,876,979, titled "Electronic commerce bridge system."

• Initial Pleadings
  While the specific dates for Dillard's answer and any counterclaims are not detailed in the available reports, defendants in such cases typically respond by denying infringement and asserting counterclaims that the patent is invalid. The subsequent settlement agreement handled the dismissal of both the plaintiff's claims and the defendant's counterclaims separately.

• 2024-08-28: Joint Stipulation of Dismissal
  After approximately eight months of litigation, the parties filed a joint stipulation for dismissal pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(ii). This joint filing indicates a mutual agreement to end the lawsuit, which is a strong indicator of a private settlement. The case was officially closed on the same day.

• Final Disposition: Dismissal with Prejudice
  The court dismissed Aml Ip's infringement claims against Dillard's with prejudice. This is a final and binding resolution that prevents Aml Ip from ever re-asserting the same claims from the '979 patent against Dillard's in the future.

  Conversely, Dillard's counterclaims (presumably for patent invalidity) were dismissed without prejudice. This procedural nuance preserves Dillard's right to raise those invalidity arguments again if another entity were to assert this patent against them in a future dispute. Each party agreed to bear its own attorneys' fees and costs, a common term in settlement agreements. No substantive motions, claim construction hearings, or trial events occurred due to the early settlement.

Parallel PTAB Proceedings

A search of the U.S. Patent and Trademark Office's Patent Trial and Appeal Board (PTAB) database found no records of inter partes review (IPR) or other post-grant proceedings filed by Dillard's or any other party against either U.S. Patent No. 7,177,838 (from the prompt's metadata) or U.S. Patent No. 6,876,979 (from the litigated case). The absence of a PTAB challenge is common in cases that settle quickly, as defendants may opt for a negotiated resolution rather than incurring the expense of a parallel validity challenge.

Plaintiff's Counsel of Record Identified as Ramey LLP

Based on a consistent pattern of representation in parallel lawsuits, the Houston-based intellectual property firm Ramey LLP serves as counsel for plaintiff Aml Ip LLC. While the specific notice of appearance for the Dillard's case was not available in public search results, press releases from the firm and litigation analytics reports confirm Ramey LLP's role in Aml Ip's litigation campaign involving the same patent-in-suit.

The legal team for Aml Ip LLC is led by the firm's founding partner.

Disclaimer: The identification of counsel is based on the firm's public announcements regarding its representation of Aml Ip LLC in identical patent litigation campaigns. Specific filings for case 7:25-cv-00156 were not publicly available to confirm if additional attorneys or local counsel have made appearances.

As of May 4, 2026, counsel of record for the defendant, Dillard's, Inc., in Aml Ip LLC v. Dillard's, Inc., Case No. 7:25-cv-00156, has not been identified in publicly available records.

A review of litigation news and federal court databases reveals no notice of appearance, answer, or other responsive pleading filed by attorneys on behalf of Dillard's in this specific matter. This suggests that either Dillard's has not yet formally retained and designated counsel for this case, or the appearance has been filed very recently and is not yet reflected in aggregated legal research databases. Filings could also be under seal, though this is less common for an initial appearance.

Note on Related Litigation

For context, in a prior and separate patent infringement case brought by the same plaintiff (AML IP, LLC v. Dillard's, Inc., Case No. 2:23-cv-00615, E.D. Tex.), Dillard's was represented by counsel from the law firm Fish & Richardson. That case, which concerned a different patent, was dismissed in August 2024. It is currently unknown whether Dillard's will retain the same firm for this new litigation in the Western District of Texas.
