Definition & Meaning

The prosecution-laches doctrine is an equitable principle in patent law that can prevent a patent holder from enforcing their patent rights if they have unreasonably delayed in pursuing their patent application. This delay must be unexplained and must have caused prejudice to the alleged infringer. The primary aim of this doctrine is to safeguard the public's rights by ensuring that patents are issued in a timely manner, thus preventing the patent holder from taking advantage of the public's investment in the technology during the delay.
