37signals LLC d/b/a Basecamp — patent litigation as defendant

37signals LLC (d/b/a Basecamp) is a privately held American software company founded in 1999 in Chicago, Illinois, by Jason Fried, Carlos Segura, and Ernest Kim, with David Heinemeier Hansson later joining as a partner and CTO. It remains headquartered in Chicago but operates as a fully remote company with no physical headquarters. Ownership is concentrated among the founders and is self-funded; Jeff Bezos's personal investment vehicle, Bezos Expeditions, acquired a minority, non-controlling stake in 2006 and is consistently described as the company's only outside investor. Headcount has been reported at roughly 60–80 employees in recent years, though third-party data aggregators list higher figures. The company does not disclose revenue publicly; its revenue is estimated in the tens of millions of dollars, and it reports being consistently profitable and debt-free.

Products and operations. 37signals is an operating software company selling subscription and self-hosted tools. Its flagship is Basecamp, a project management and team collaboration platform. HEY (hey.com) is its email and calendar service. It also created and maintains the open-source Ruby on Rails web framework. Newer lines include ONCE (once.com), a self-hosting platform, and the self-hosted/open-source products Campfire (group chat), Writebook (publishing), and Fizzy (kanban). Earlier products such as Highrise and Backpack are discontinued or maintenance-only.

Patent-litigation posture. The company is not a patent plaintiff. Its single tracked appearance is as a defendant: an operating company defending against an NPE-style suit. In Web 2.0 Technologies, LLC et al. v. 37signals LLC d/b/a Basecamp (N.D. Ill., No. 1:23-cv-00230, filed Jan. 13, 2023, Judge John Robert Blakey), plaintiffs Web 2.0 Technologies LLC and Pennar Software Corporation asserted U.S. Patent Nos. 6,845,448 ("Online Repository for Personal Information") and 8,117,644 ("Method and System for Online Document Collaboration") against Basecamp. Venue was the Northern District of Illinois, the defendant's home district, not a plaintiff-friendly venue such as the Eastern District of Texas.

Outcome. On March 25, 2024, the court granted 37signals' Rule 12(b)(6) motion, finding the asserted claims directed to abstract ideas ineligible under 35 U.S.C. § 101, and dismissed without prejudice with leave to amend. The parties then stipulated to dismissal with prejudice, entered June 2024.
