Defendant
1 case as defendant.
Company overview. "Citizens National Bank" is a common name shared by many unrelated U.S. community banks. The tracked case (RPX Insight, case 2:15-cv-01168) names simply "Citizens National Bank" as defendant, and I could not conclusively verify which legal entity is the defendant — candidates include Citizens National Bank of Texas (Waxahachie), Citizens National Bank, N.A. (Bossier City, LA), The Citizens National Bank (Bluffton, OH), and others in TN, KY and MI. No headquarters, founding year, ownership or size figure can be reliably tied to the specific defendant, so none is asserted here. Based on the case record, the defendant is an operating community bank, not a holding-company registrant appearing under a distinct name.
Products / services / operations. The suit's own docket indicates the accused technology was consumer digital banking. An August 2016 order in the case concerns "the portion of the lawsuit involving the supplier, Malauzai Software, Inc.," an Austin-based vendor of mobile/online banking applications for community banks. That points to mobile banking and account-access services as the accused functionality, though the docket does not itemize the bank's full product lines.
Patent-litigation posture. This is an operating company defending against a patent-assertion suit: 0 plaintiff cases, 1 defendant case. The plaintiff, Plano Encryption Technologies, LLC (PET), is a Texas NPE whose stated "sole business" is licensing and enforcing patents; its USPTO filing lists real parties-in-interest PET and parent Koba Holdings, LLC, owner of U.S. Patent No. 5,974,550. PET asserted encryption and tamper-resistant key-module patents ('550, '399, '858) in a campaign against banks and later retailers. The suit was filed in the plaintiff-friendly Eastern District of Texas, Marshall Division, before Judge Rodney Gilstrap.
Notable case. Plano Encryption Technologies, LLC v. Citizens National Bank, No. 2:15-cv-01168-JRG, filed June 29, 2015, was PET's first bank suit and was cited in PET's later demand letters to other Texas banks. It was consolidated for pretrial purposes into lead case 2:15-cv-1273 and closed September 23, 2016, with dismissal with prejudice after the parties' joint settlement and mediation motions. The broader PET campaign generated related declaratory-judgment litigation, including Jack Henry & Associates, Inc. v. Plano Encryption Technologies LLC (Fed. Cir. 2018), which addressed personal jurisdiction based on demand letters.
Plano Encryption Technologies, LLC sued Citizens National Bank for infringement. The case was dismissed, as were the majority of the bank cases, most with prejudice.
