AML IP LLC v. Callaway Corp

Case Overview and Background

This patent infringement lawsuit pits AML IP LLC, a Texas-based entity, against Callaway Golf Company in a dispute over e-commerce technology. AML IP is a non-practicing entity (NPE), also known as a patent assertion entity, that generates revenue by licensing and litigating patents. It has a documented history of asserting patents, often related to e-commerce, against a wide range of companies. The defendant, Callaway Golf Company, is a well-known operating company that manufactures and sells golf equipment and accessories. The lawsuit alleges that Callaway's systems for processing online purchases, which likely include its customer-facing e-commerce platform, infringe on AML IP's patent rights.

The case was filed on April 17, 2026, in the Marshall Division of the U.S. District Court for the Eastern District of Texas and has been assigned case number 2:26-cv-00310. This venue is historically popular for patent plaintiffs due to its local rules, experienced judiciary, and reputation for moving cases along relatively quickly. The case has been assigned to Judge Rodney Gilstrap, who manages one of the largest patent dockets in the United States. The sole patent-in-suit is U.S. Patent No. 7,177,838, which is titled "Method and apparatus for conducting electronic commerce transactions using electronic tokens." The '838 patent, which has a priority date of 2000, generally describes a system for purchasing or renting products and services over a network using electronic tokens that can be acquired online or offline.

The case is notable as it reflects a continuing pattern of litigation by AML IP, which has previously asserted other e-commerce patents against retailers and other businesses. The '838 patent itself has a history of being used in litigation campaigns by a prior owner and has been criticized by the Electronic Frontier Foundation as claiming an abstract idea that should be ineligible for patent protection under 35 U.S.C. § 101. This assertion against a major operating company like Callaway, which has its own history of patent litigation, albeit typically as a plaintiff defending its golf-related technology, signals a potential high-stakes conflict. Given the patent's subject matter and prior scrutiny, key issues in the case will likely include claim construction and a challenge to the patent's validity as an abstract idea under the Supreme Court's Alice framework.

Legal Developments and Case Status

As of May 1, 2026, the patent infringement lawsuit AML IP LLC v. Callaway Corp. is in its earliest procedural stages. Having been filed only two weeks prior, on April 17, 2026, significant legal developments are still forthcoming.

Chronological Case Events:

• 2026-04-17: Complaint Filed
  AML IP LLC filed a patent infringement complaint against Callaway Golf Company in the U.S. District Court for the Eastern District of Texas (Marshall Division). The suit alleges that Callaway's e-commerce systems, which use electronic tokens for transactions, infringe upon U.S. Patent No. 7,177,838. The complaint was filed by William P. Ramey, III of Ramey LLP on behalf of AML IP, LLC. On the same day, a Notice of Filing of Patent/Trademark Form (AO 120) was sent to the U.S. Patent and Trademark Office, and the plaintiff filed its required disclosure statement under Federal Rule of Civil Procedure 7.1.

Current Posture and Expected Next Steps:

The case is currently open and pending. The immediate next step is for AML IP to formally serve the complaint on Callaway Corp. Following service, Callaway will be required to respond to the complaint, typically within 21 days, unless an extension is granted. Callaway's response will likely take the form of an Answer, which may include affirmative defenses and counterclaims, or a pre-answer motion, such as a motion to dismiss.

Given the nature of the patent and the parties involved, several developments can be anticipated:

• Answer and Counterclaims: Callaway is expected to deny infringement and assert that the '838 patent is invalid. Common invalidity arguments in similar cases include lack of patentable subject matter under 35 U.S.C. § 101, particularly based on the Supreme Court's decision in Alice Corp. v. CLS Bank Int'l, which limited patents on abstract ideas implemented on a generic computer. The '838 patent, which claims a method for using electronic tokens in commerce, has been previously criticized as an abstract "e-money" concept.
• Motion to Dismiss or Transfer: Callaway may file a motion to dismiss under Rule 12(b)(6) for failure to state a claim, potentially arguing the patent is invalid on its face as an abstract idea. Alternatively, they could seek to transfer the case to a different venue, such as the Southern District of California where Callaway is involved in other litigation.
• Parallel PTAB Proceedings: It is common for defendants in such cases to challenge the validity of the asserted patent at the Patent Trial and Appeal Board (PTAB) by filing a petition for inter partes review (IPR). An IPR filing would likely be accompanied by a motion to stay the district court litigation pending the PTAB's decision.

Context from Plaintiff's Litigation History:

AML IP, LLC is a known patent assertion entity (PAE) that has filed numerous lawsuits against large retailers and e-commerce companies. Its litigation campaigns often target companies' online sales platforms. A review of AML IP's past cases shows a pattern of resolving disputes in the early stages, frequently through voluntary dismissals or joint stipulations of dismissal, which often indicate a private settlement. These resolutions typically occur before significant litigation milestones like claim construction or trial.

As of this date, no answer, dispositive motions, or notice of any parallel PTAB proceedings have been filed in this case.

Plaintiff's Counsel of Record

As of May 1, 2026, the initial complaint is the only substantive filing on the docket for this case. Therefore, the counsel of record for the plaintiff, AML IP LLC, consists of the attorney who signed and filed that initial document.

• Name: William P. Ramey, III
• Role: Lead Counsel
• Firm: Ramey LLP (Houston, Texas)
• Noteworthy Experience: Mr. Ramey is a prolific filer of patent infringement lawsuits in Texas federal courts, frequently representing patent assertion entities in litigation campaigns across various technology sectors.

Defendant's Counsel of Record

As of May 4, 2026, the case is in its earliest stages, having been filed on April 17, 2026. A review of the docket for AML IP LLC v. Callaway Corp., 2:26-cv-00310, in the U.S. District Court for the Eastern District of Texas reveals that counsel for the defendant, Callaway Corp., has not yet filed a notice of appearance or any responsive pleadings.

The summons was issued on April 18, 2026, but as of today, there is no entry on the docket confirming that service has been completed. Typically, a defendant has 21 days to respond after being served with the complaint. Given the filing date, Callaway's appearance and response are expected in the coming weeks.

Therefore, there is currently no counsel of record for the defendant. Information on legal representation for Callaway Corp. will become available only after their attorneys make their first filing in the case.
