Defendant
1 case as defendant.
Trane Technologies Company LLC is the U.S. operating entity of its Irish-domiciled parent company, Trane Technologies plc (NYSE: TT). Headquartered in Swords, Ireland, the modern company was formed in 2020 following a spin-off from Ingersoll Rand, but its origins trace back to a Wisconsin plumbing business founded in 1885. Trane Technologies is a major global manufacturing company with approximately 44,000 employees and annual revenues of around $21.6 billion.
As a global climate control manufacturer, the company designs, sells, and services a wide range of products for commercial and residential use. Its two primary brands are Trane, which focuses on heating, ventilation, and air conditioning (HVAC) systems and building controls, and Thermo King, a leader in transport refrigeration for trucks, trailers, and shipping containers. The company also offers solutions for specialized sectors such as data center cooling, life sciences, and building automation, and owns other brands including American Standard (residential HVAC).
Trane Technologies' patent litigation profile is that of an operating company defending itself against patent assertions. The company has been named as a defendant in one tracked case and has not appeared as a plaintiff. This defensive posture is common for large manufacturers. The single tracked case was filed in the U.S. District Court for the Eastern District of Texas, a common venue for patent infringement lawsuits.
The company's only tracked litigation is a 2026 suit filed by Portus Singapore PTE Ltd & Portus Pty Ltd. The plaintiff, Portus, has filed similar patent infringement lawsuits against other large technology and appliance manufacturers. Past reporting describes Portus as owning patents related to smart home and IP video surveillance technology, which it asserts against "infringement targets and licensees."
The accused products are home security systems and their related control systems.
