Proper use of a trademark is essential for its continued protection. Companies must properly use their trademarks in order to aid the consumers who depend upon them and to prevent a trademark from becoming generic. And never assume something is generic. Always use a trademark as an adjective modifying a noun. Instead, change the descriptive word from singular to plural.
Trademarks are products or services, never actions.
