Our history

Dennemeyer: a history of 50 years of innovations

The foundation of Dennemeyer's extraordinary success story was laid 50 years ago in Luxembourg. Since 1962, Dennemeyer has earned a reputation for setting the service standard in the IP industry and remains dedicated to discovering and developing improved ways to protect and preserve intellectual property rights around the world. Initially a patent law firm, Dennemeyer soon became a full-service provider, addressing our services to the entire chain of IP management. A succession of innovations has transformed the company headquartered in Luxembourg into one of the world's largest IP service providers.
