Fidelity National Information Services (FNIS)

I'll research this company before writing the profile.

Let me verify the litigation context and the plaintiff entity.

Fidelity National Information Services, Inc. (FIS) — FIS is a publicly traded financial technology company headquartered in Jacksonville, Florida, listed on the NYSE under "FIS" and a member of the Fortune 500 and S&P 500. Its roots date to 1968 (founded in Little Rock as Systematics); the current holding company was incorporated in 2001. It is an independent public company, not a subsidiary. Reported headcount is roughly 44,000–50,000, and FY2024 revenue was approximately $10.1 billion following the spin-off of its Worldpay merchant business. (Employee and revenue figures vary by source and reporting date.)

Operations — FIS sells mission-critical technology to banks, credit unions, capital markets firms and businesses. Major offerings include core banking processing software, digital and mobile banking platforms, payment processing and payment hubs (e.g., its Open Payment Framework), money-movement and treasury services, fraud and risk management, securities processing, trading and lending, and wealth/retirement solutions. It is one of the largest U.S. core banking vendors, competing with Fiserv and Jack Henry.

Patent-litigation posture — FIS is an operating company and a pure defendant in the tracked data: 1 case as defendant, 0 as plaintiff. This is the classic profile of a technology vendor targeted by a non-practicing entity rather than an active two-way litigant. The single tracked suit sits in the Eastern District of Texas, a historically plaintiff-friendly venue for patent holders.

Notable case — Plano Encryption Technologies, LLC v. Fidelity National Information Services (FNIS), No. 2:16-cv-00803 (E.D. Tex., Judge Rodney Gilstrap), filed July 19, 2016 and closed September 27, 2016, asserted U.S. Patents 5,991,399 and 5,974,550 on encryption and online-transaction security against FIS's online/mobile banking services. The plaintiff, Plano Encryption Technologies (PET), is a Texas LLC wholly owned by Koba Holdings, LLC and associated with attorney Bradley Liddle; it is characterized by RPX, Unified Patents and Stanford's NPE database as a patent assertion entity that acquired former Intel patents and ran a single campaign against banks and mobile-app companies, later transferring the portfolio to Honeyman Cipher. FIS separately filed a Delaware declaratory-judgment action (No. 1:15-cv-00777) against PET and Koba Holdings, which was dismissed for lack of personal jurisdiction.
