Siemens Energy, Inc. is the U.S. subsidiary of Siemens Energy AG, a global leader in energy technology headquartered in Munich, Germany. Siemens Energy AG was established in April 2020 as a spin-off from Siemens AG, though its operational legacy in the energy sector dates back over 150 years to the founding of Siemens in 1847. The parent company is publicly traded on the Frankfurt Stock Exchange under the ticker ENR. Globally, Siemens Energy employs approximately 100,000 individuals across more than 90 countries and reported a trailing 12-month revenue of $46.5 billion (USD) as of March 31, 2026. Its U.S. headquarters is located in Orlando, Florida, with a team of 12,000 across 84 locations, including over 20 manufacturing facilities.
The company's core operations encompass a broad range of products, solutions, and services across nearly the entire energy value chain. This includes the manufacturing of equipment for power generation and transmission, such as gas and steam turbines, generators, transformers, circuit breakers, compressors, control systems, and electrolyzers. Siemens Energy also plays a significant role in renewable energy through its wind power subsidiary, Siemens Gamesa. Their mission is to support the global energy transition by driving decarbonization, expanding renewables, strengthening electrical grids, and transforming conventional power.
In terms of patent litigation, Siemens Energy, Inc. operates as a defendant, consistently defending against patent infringement suits. The company has been named as a defendant in all two of its tracked cases, with no appearances as a plaintiff. Both recorded cases, Sampo IP, LLC v.

Siemens Energy, Inc., were filed in March 2013 in the United States District Court for the Eastern District of Texas, a venue known for its plaintiff-friendly litigation environment.
