Tabasco is a state in Mexico, though; how were its trademark owners able to obtain the name?

Legally, it's due to context of use.

eg Microsoft doesn't own my ability to use the word windows as it pertains to the physical objects I look out of my house through. I can start a window company, and use the word windows accordingly. We have the clearest, best windows, of any window manufacturer.

Thanks for explaining that to me. To add to the confusion, tabasco is also a pepper cultivar named after the Mexican state.
