Patents and Trademarks

What are Patents and Trademarks?

patent is a government license that gives the holder exclusive rights to a process, design, or new invention for a designated period of time.  In the U.S. granting a patent means “to exclude others from making, using, offering for sale, or selling the invention throughout the United States or importing the invention into the United States” for a limited time.

trademark is a word, name, symbol or device which is used in trade with goods to indicate the source of the goods and to distinguish them from the goods of others.  Trademark rights may be used to prevent others from using a confusingly similar mark, but not to prevent others from making the same goods or from selling the same goods or services under a clearly different mark.
