In my law class we have been talking a lot about trademark and what goes along with that.
Trademark Infringement and Unfair Competition laws protect the commercial value of names, words, symbols and personal identities.
Some examples of this are Dumpster, Xerox and Kleenex – all used to describe the actual product instead of the name brand.
These laws are created through adoption and use. You create your mark and you want to protect it against other marks. Registration lasts 10 years and then needs to be renewed.
That is the tricky world of the trademark all summed up.
