Defendant
1 case as defendant.
Schlage Lock Company LLC ("Schlage") is an American lock and door-hardware manufacturer and a wholly owned subsidiary of Allegion plc (NYSE: ALLE), the Irish-domiciled security-products company spun off from Ingersoll Rand in December 2013. The Schlage brand dates to 1920, when Walter Schlage founded the business in San Francisco. Schlage Lock Company LLC is headquartered in the Indianapolis area — its operations are tied to Allegion's Americas regional headquarters in Carmel, Indiana, and manufacturing and a technical center in Indianapolis. Allegion reported net revenues of roughly $3.65 billion for 2023 and has stated headcount above 11,000 globally; Schlage-specific revenue and employee figures are not separately disclosed.
Schlage manufactures mechanical and electronic door hardware for residential and commercial use. Product lines include deadbolts, knobs and levers, keypad and touchscreen electronic locks, smart deadbolts (e.g., Schlage Connect and Schlage Encode families) with Z-Wave/Zigbee/Wi-Fi connectivity, key systems and cylinders (Everest, Primus), mortise and cylindrical commercial locks, electrified locks, exit devices, door closers, readers, controllers, power supplies and access-control software. It is an operating company with real manufacturing, engineering and distribution operations, not a shell or licensor.
Patent-litigation posture: In the tracked data Schlage appears only as a defendant (1 case, 0 as plaintiff), which is consistent with an operating company targeted by a patent holder rather than an active two-way litigant. The single tracked suit was filed in the plaintiff-friendly Eastern District of Texas, Marshall Division.
Notable case: Smart Lock, LLC v. Schlage Lock Company LLC (2:16-cv-01019-JRG-RSP, E.D. Tex., filed Sept. 16, 2016).

The case reflects the electronic/smart-lock technology area where Schlage faces third-party patent assertion. No outcome details are available in the tracked record.
