Patent
A government-granted right that gives an inventor exclusive control over the making, using, and selling of an invention for a limited period.
What It Means
A patent is a legal instrument issued by a national patent office, in the United States, the U.S. Patent and Trademark Office (USPTO). It grants the patent holder the exclusive right to prevent others from making, using, selling, or importing the patented invention for a defined term. In exchange for this monopoly, the inventor must publicly disclose the full details of the invention so that others can learn from it and build on the knowledge after the patent expires. U.S. utility patents filed after June 8, 1995 last 20 years from the filing date. Patents are territorial, meaning a U.S. patent only provides protection within the United States. To protect an invention in other countries, separate patent applications must be filed in each jurisdiction. The patent system is designed to balance innovation incentives with public access: the temporary monopoly rewards R&D investment, while the disclosure requirement ensures that technological knowledge eventually enters the public domain. Patents are a cornerstone of intellectual property law and are critical to industries ranging from pharmaceuticals to semiconductors.
