About Aspirin
Aspirin was registered as a Bayer trademark in 1899 for acetylsalicylic acid. Germany lost the trademark in several countries as war reparations after 1919, which is why aspirin is a generic word in the United States, Britain and France but a Bayer brand in most of the rest of the world.
