The Subway sandwich chain is trying to trademark “footlong” and is issuing cease-and-desist letters to other companies that use the term. Some companies, such as Pizza Hut, are opposing the trademark registration.

I don’t see what the problem is — Subway’s sandwich isn’t 12″ long, it’s only 11″. I can foresee the day when I see a poster that urges me to buy a Subway footlong(TM) with an asterisk to a footnote that says “Subway’s registered trademark for it’s 11″ hero sandwich.”
