What is a patent?

In the U.S., a patent gives the patent holder has the right to exclude others from making, using, selling, offering to sell, and importing any patented invention. Thus, a patent does not necessarily provide the holder any affirmative right to practice a technology. Instead, it provides the right to exclude others from practicing it. Patent claims are the legal definition (often called the “metes and bounds”) of an inventor’s protectable invention.
