The Only Card LLC v. Eternal Inc

Case Dossier: The Only Card LLC v. Eternal Inc

Case Overview

This patent infringement lawsuit is part of a broad litigation campaign by the non-practicing entity (NPE) The Only Card LLC. The plaintiff is asserting a single patent, U.S. Patent No. 8,152,059, against Eternal Inc.'s secure commercial transaction and payment processing systems. The Only Card LLC has filed numerous similar lawsuits against a wide array of banks, credit unions, and retailers, suggesting a monetization campaign targeting companies that utilize standard financial transaction technologies. While the corporate identity of "Eternal Inc" is not definitively established in initial court filings, the context of the litigation campaign suggests it is likely a payment processing company, such as Eternity Payments, which offers credit card processing, point-of-sale terminals, and e-commerce gateways.

Technology and Procedural Posture

The patent-in-suit, U.S. Patent No. 8,152,059, is titled “Secure commercial transactions system.” The technology described involves a transaction card system with two distinct operational modes. One mode is for normal transactions (e.g., using a standard PIN), while a second, covert mode is triggered by a different input (a "panic PIN" or alternate biometric scan) that appears to conduct a normal transaction but simultaneously sends a duress signal to law enforcement or a security service. The Only Card LLC alleges that Eternal Inc.'s systems, which likely process standard EMV chip-card transactions, infringe upon this patent. In parallel cases, the plaintiff's infringement theory appears to contend that standard EMV card functionality constitutes the "second operation mode" described in the patent.

The case was filed on April 16, 2026, in the U.S. District Court for the Northern District of Georgia and has been assigned to Senior Judge Richard W. Story. The plaintiff has filed multiple other cases from this same campaign in this venue and before the same judge. The Northern District of Georgia is a moderately active forum for patent disputes but is not one of the high-volume venues like the Western District of Texas or the District of Delaware. The case is notable primarily due to its place within a large-scale NPE assertion effort that tests the bounds of patent claims against ubiquitous, standardized financial technology.

As of May 4, 2026, the patent infringement litigation in The Only Card LLC v. Eternal Inc is in its earliest stages, with no major legal developments having occurred since the case was filed in the U.S. District Court for the Northern District of Georgia.

Trial, Verdict, and Final Disposition

The case remains open and has not been scheduled for trial. There have been no verdicts, settlements, or dismissals recorded in the court docket.

Parallel PTAB Proceedings

A search for inter partes review (IPR) or post-grant review (PGR) proceedings before the Patent Trial and Appeal Board (PTAB) for U.S. Patent No. 8,152,059 has not revealed any parallel challenges involving Eternal Inc.

It is worth noting that the plaintiff, The Only Card LLC, has filed other patent infringement lawsuits in the same judicial district against different financial institutions, suggesting a broader litigation campaign. One of these cases, also before Judge Story, resulted in a notice of settlement in principle within two months of being filed.

As of May 4, 2026, counsel for the plaintiff, The Only Card LLC, has not yet filed a formal notice of appearance in the case of The Only Card LLC v. Eternal Inc., 2:26-cv-00115. However, based on the complaint filing and consistent representation in numerous other patent infringement cases filed by The Only Card LLC in the same district, the following attorneys and firms are identified as representing the plaintiff.

Lead Counsel

John Wade Carpenter

• Firm: Law Offices of John W. Carpenter, LLC (Metairie, LA)
• Role: Lead Counsel
• Experience: John W. Carpenter has over 50 years of experience in intellectual property law and is a registered patent attorney with the U.S. Patent and Trademark Office. He has represented The Only Card LLC as lead counsel in a series of patent infringement lawsuits asserting the same patent (U.S. Patent No. 8,152,059).

Local Counsel

John Thomas Sparks, Sr.

• Firm: Austin & Sparks, P.C. (Atlanta, GA)
• Role: Local Counsel
• Experience: John T. Sparks, Sr. and his firm frequently serve as local counsel for The Only Card LLC in its Georgia-based patent litigation. The firm has nearly 70 years of collective litigation experience, handling a variety of commercial disputes and litigation matters.

This legal team structure is consistent across multiple recent cases filed by The Only Card LLC in the Northern District of Georgia. For instance, in The Only Card, LLC v. The Citizens Bank of Georgia (2:25-cv-00408), court records explicitly name the "Law Offices of John W. Carpenter, LLC" and "Austin & Sparks, P.C." as Plaintiff's Counsel. Similarly, in The Only Card, LLC v. River City Bank (2:26-cv-00100), John Thomas Sparks, Sr. is listed as counsel for the plaintiff.

Defendant's Counsel of Record Not Yet Available

As of May 4, 2026, counsel for the defendant, Eternal Inc., has not made a formal appearance on the public docket for the matter of The Only Card LLC v. Eternal Inc., case number 2:26-cv-00115, in the U.S. District Court for the Northern District of Georgia.

The lawsuit was initiated on April 16, 2026. Under the Federal Rules of Civil Procedure, a defendant typically has 21 days to file a responsive pleading, such as an answer or a motion to dismiss, after being served with the complaint. During this period, the defendant secures legal representation who will then file a notice of appearance with the court.

Given that less than three weeks have passed since the initial filing, it is not unusual that Eternal Inc.'s legal team has not yet been identified on the court's record. A thorough search of the official court docket and legal news reporting has yielded no information regarding the law firm or individual attorneys retained by the defendant. Information on counsel for Eternal Inc. will be added once an appearance is formally entered.
