Anybody know why companies say "ProductX is a trademark or registered trademark of CompanyXYZ"? Why mention both, and not just one or the other? I found that this statement is prevalent in numerous websites, so there has to be a legitimate reason.

I Googled it and even contacted (phoned) www.uspto.gov for info, but they said that they have nothing to do with providing the statements. That's up to the legal dept of companies.

Interesting indeed.
