State Farm Mutual Automobile Insurance Co.

State Farm Mutual Automobile Insurance Company ("State Farm") is a U.S. mutual insurance group headquartered at One State Farm Plaza, Bloomington, Illinois. Founded in 1922 by George J. Mecherle as a farm-focused auto insurer, it remains policyholder-owned and is not publicly traded, operating through a group of roughly 14 property-casualty and two life insurance companies. Fortune reported FY2024 revenues of approximately $132.3 billion with 64,273 employees, and about 96 million policies and accounts in force as of 2025. It is private, not a subsidiary.

Operations. State Farm is one of the largest U.S. writers of personal lines insurance: private passenger auto, homeowners, and other property-casualty coverages sold through a large exclusive-agent network, plus life and health lines and financial-services offerings (banking and mutual funds). It is also a major advertiser and operates consumer mobile applications and digital claims/servicing tools.

Patent-litigation posture. The structured data show a single tracked case, with State Farm as defendant and zero as plaintiff — the profile of an operating company defending against an asserted patent, not an NPE or a two-way litigant.

Notable case. Plano Encryption Technologies, LLC v. State Farm Mutual Automobile Insurance Co., No. 2:16-cv-01072 (E.D. Tex., Marshall Division, Judge Rodney Gilstrap), filed October 3, 2016. Plaintiff Plano Encryption Technologies (PET) was a Texas-formed, Koba Holdings-owned entity whose sole officer/employee, Bradley D. Liddle, is linked in RPX reporting to other NPEs. PET asserted U.S. Patents 5,991,399 and 5,974,550 — originally issued to Intel and covering tamper-resistant software modules and secure data distribution — against State Farm's mobile apps. The case was consolidated into lead case 2:16-cv-01032 and dismissed with prejudice on December 27, 2017. State Farm separately petitioned for inter partes review of both patents (IPR2017-01721 and IPR2017-01783).
