AML IP LLC v. Brinker International Payroll Company, L.P.

In a case highlighting the continued patent risk for retail and hospitality companies, patent assertion entity (PAE) AML IP LLC has filed a lawsuit against Brinker International Payroll Company, L.P., the parent company of major restaurant chains Chili's Grill & Bar and Maggiano's Little Italy. Filed on April 17, 2026, in the U.S. District Court for the Northern District of Texas, the suit alleges that Brinker's systems for processing online orders and payments infringe on AML IP's patent. The case is assigned to Judge Reed O'Connor. While the specific accused instrumentality has not been detailed in court documents, the complaint targets the methods Brinker uses for e-commerce, likely implicating the online ordering platforms, mobile apps, and digital payment systems used by its restaurant brands.

The lawsuit asserts a single patent, U.S. Patent No. 7,177,838, titled "Method and apparatus for conducting electronic commerce transactions using electronic tokens." The patent, filed in 2000, generally describes a system where electronic tokens can be purchased and used for online transactions, potentially removing the need for direct credit card use in every purchase. This case is part of a broader litigation campaign by AML IP, which has filed similar suits against numerous other companies in the retail, e-commerce, and restaurant sectors, asserting patents related to online transaction technology. The choice of the Northern District of Texas is significant, as the district has become a more frequent venue for patent cases since the Supreme Court's 2017 TC Heartland decision limited where patent suits can be filed.

The case is notable as it represents a persistent trend of non-practicing entities (NPEs) targeting the increasingly complex digital infrastructure of operating companies. The '838 patent itself has a contentious history; in 2018, the Electronic Frontier Foundation (EFF) criticized it as an overly broad and abstract patent, arguing it claimed the long-existing concept of using tokens for currency, simply applied to a computer. This history suggests that Brinker may pursue an invalidity defense based on the patent covering an abstract idea, a common strategy against business method patents following the Supreme Court's Alice v. CLS Bank decision. The outcome of this case could influence how other restaurant and retail chains assess patent risk associated with their customer-facing digital platforms.

Litigation Active as of Early May 2026

As of the current date of May 4, 2026, the patent infringement lawsuit filed by AML IP LLC against Brinker International Payroll Company, L.P. is in its earliest procedural stages. Having been filed only a few weeks prior on April 17, 2026, in the U.S. District Court for the Northern District of Texas, there have been no substantive legal rulings or significant developments in the case itself. The docket consists primarily of the initial filings.

Key Legal Developments (Chronological)

• 2026-04-17: Complaint Filed. AML IP LLC, represented by the Houston-based intellectual property firm Ramey LLP, filed its complaint against Brinker International Payroll Company, L.P.. The suit alleges that Brinker's online and mobile ordering systems—which facilitate e-commerce transactions for its restaurant chains like Chili's—infringe U.S. Patent No. 7,177,838 ("Method and apparatus for conducting electronic commerce transactions using electronic tokens"). The case was assigned to District Judge Reed O'Connor. This filing is part of a large-scale litigation campaign by AML IP, which filed numerous similar lawsuits on the same day against other major companies in both the Northern and Eastern Districts of Texas, including against Marriott International, Cinemark, and Dave & Buster's.

• Current Status (2026-05-04): Awaiting Answer. Brinker International has not yet filed its answer or any responsive pleading to the complaint. Under the Federal Rules of Civil Procedure, a defendant typically has 21 days to respond after being served, meaning Brinker's deadline is approaching. No substantive motions, such as a motion to dismiss under § 101 for patent ineligibility (an Alice motion), have been filed. The case remains open and active.

Parallel Proceedings and Patent History

There are no records of any inter partes review (IPR) or other post-grant proceedings having been filed at the Patent Trial and Appeal Board (PTAB) by Brinker against the '838 patent as of this date. However, given the broad assertion campaign by AML IP, it is a common defensive strategy for defendants to collectively or individually file IPRs to challenge the patent's validity.

The '838 patent has a history of being characterized by critics as overly broad. In 2018, the Electronic Frontier Foundation (EFF) featured it as a "Stupid Patent of the Month," arguing that it claimed the abstract and long-standing idea of using tokens for commerce, simply applied to an internet context. This history suggests that a primary defense for Brinker will likely be to challenge the patent's validity under 35 U.S.C. § 101, which bars patents on abstract ideas, as established in Alice Corp. v. CLS Bank International.

Anticipated Future Developments

Based on the typical trajectory of patent lawsuits initiated by non-practicing entities and the history of the asserted patent, the following developments are anticipated:

1. Answer and Counterclaims: Brinker is expected to file an answer denying infringement and counterclaims seeking a declaratory judgment that the '838 patent is invalid and not infringed.
2. Early Motion to Dismiss: Brinker may file a Rule 12(b)(6) motion to dismiss, arguing that the patent's claims are invalid on their face as being directed to an abstract idea. Judge O'Connor has previously ruled on such Alice motions, sometimes denying them at the pleadings stage.
3. Venue Challenge or Case Consolidation: While less common since TC Heartland, defendants sometimes challenge venue. Given the number of parallel cases filed by AML IP, there may be motions to consolidate for pre-trial proceedings, although none have been filed yet.
4. Claim Construction (Markman Hearing): If the case proceeds, the parties will dispute the meaning of key terms in the patent's claims, culminating in a Markman hearing where the judge will issue a binding interpretation of those terms.
5. Settlement or Dismissal: Many of AML IP's previous lawsuits against other retailers have ended in joint stipulations for dismissal, suggesting settlements are a common outcome. The terms of such dismissals—whether with or without prejudice—can indicate the strength of the defendant's position during negotiations.

At this very early stage, the litigation's outcome remains uncertain and will depend on Brinker's defensive strategy and Judge O'Connor's future rulings on validity and claim construction.

Plaintiff's Counsel

Based on the complaint filed in this case and other parallel lawsuits initiated by the plaintiff, the counsel of record for AML IP LLC is the intellectual property law firm Ramey LLP. As the case is still in its initial phase, formal appearances may not be fully updated on the docket, but the attorneys signing the complaint are listed below.

• William P. Ramey, III - Lead Counsel

  • Firm: Ramey LLP (Founding Partner), Houston, Texas.
  • Note: Ramey is a prolific patent litigator who frequently represents non-practicing entities (NPEs) in large-scale assertion campaigns across the country, particularly in Texas district courts. He has been involved in numerous lawsuits on behalf of AML IP asserting the same '838 patent against other major companies. Ramey and his firm have faced scrutiny and sanctions in other jurisdictions for litigation conduct.

• De-Ann Sheppard - Of Counsel

  • Firm: Ramey LLP, Houston, Texas.
  • Note: While public information specifically detailing De-Ann Sheppard's patent litigation experience is limited, her association with Ramey LLP and signature on complaints, such as the one in this case, indicate her role in the firm's patent assertion practice. The search results did not provide a detailed professional biography or a list of notable past cases specifically for her.

• Anne-Marie Dao - Of Counsel

  • Firm: Ramey LLP, Houston, Texas.
  • Note: Similar to De-Ann Sheppard, Anne-Marie Dao is listed on the complaint for AML IP. There is a patent litigator with the same name at Sheppard Mullin's San Diego office, but it is not confirmed if this is the same individual now associated with Ramey LLP, as the firm's website does not list her. Her specific role and experience within Ramey LLP's patent campaigns are not detailed in available public records.

Counsel for Defendant Brinker International Not Yet on Record

As of May 4, 2026, counsel for the defendant, Brinker International Payroll Company, L.P., has not yet formally appeared on the court docket. The case was filed on April 17, 2026, and the defendant's answer or other response to the complaint is not yet due.

Given that the deadline for a response has not passed, no notices of appearance have been filed. It is standard for defense counsel to make a formal appearance when filing the initial responsive pleading, such as an answer or a motion to dismiss.

While no attorneys have appeared, large corporate defendants like Brinker International often retain national law firms with deep patent litigation experience, particularly those with strong Texas practices. Firms known for representing major technology and retail companies in patent disputes include Sidley Austin, Fish & Richardson, and others with substantial intellectual property groups. However, any specific firm's involvement in this case is speculative until a notice of appearance is filed on the docket.
