What is the statute of limitations for utility patents?

The statute of limitations for utility patents is indeed 20 years from the filing date. This duration is established under U.S. patent law, specifically in Title 35 of the United States Code. The 20-year term begins when a patent application is filed, which incentivizes inventors to disclose their inventions to the public in exchange for a limited period of exclusive rights.

This timeframe is crucial because it balances the interests of inventors in securing returns on their innovations with the public's interest in accessing new technologies and products after a reasonable period. Once the 20 years expire, the invention enters the public domain, allowing others to use, make, or sell it without infringement concerns.

Understanding this timeline is vital for patent holders and those considering investing in or developing new technologies under patent protections.
