A more thorough explanation:

Definition: Sleeping on rights is a legal term that refers to the unreasonable delay in pursuing a right or claim, especially an equitable one, in a way that prejudices the party against whom relief is sought. It is also known as laches.

For example, if someone has a legal claim against another person but waits too long to pursue it, the court may deny relief on the grounds of laches. This is because the delay may have caused prejudice to the defendant, such as loss of evidence or inability to defend themselves properly.

In patent law, sleeping on rights can be used as a defense against a claim of patent infringement. If the patentee did not timely enforce their patent rights, they may not be able to claim infringement later on.

The doctrine of laches is an equitable principle that allows a court to withhold relief if it would be unfair or unjust to grant it. This is because the delay in pursuing the claim may have caused harm to the defendant that cannot be undone.

Overall, sleeping on rights is a legal concept that emphasizes the importance of timely pursuing one's legal rights and claims to avoid prejudice to the other party.
