Patents, Trademarks, and Copyrights are three types of intellectual
property protection. They are different and serve different purposes.
Patents protect inventions, and improvements to existing inventions.
Trademarks include any word, name, symbol, or device, or any combination,
used, or intended to be used in commerce to identify and distinguish the
goods of one manufacturer or seller from goods manufactured or sold by
and to indicate the source of the goods. Service marks include any
word, name, symbol, device, or any combination, used, or intended to be
used, in commerce, to identify and distinguish the services of one provider
from services provided by others, and to indicate the source of the
services. Copyrights protect literary, artistic, and musical works. For
general information, publications and other copyright related topics, you
