Getting Started

The U.S. Government grants a patent to an inventor "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."  A trademark is a word, phrase, symbol or design, or combination of words, phrases, symbols or designs, which identifies the source of goods or services of one party from those of another. A copyright protects works of authorship, such as writings, music, and works of art that have been tangibly expressed. See:
