Understanding the Doctrine of Intervening Rights in Patent Law
Definition & Meaning
The doctrine of intervening rights is a legal principle that protects individuals or businesses who have relied on the original claims of a patent. When a patent is reissued with broader claims than those in the original patent, this doctrine allows those who have already practiced the invention to continue doing so without facing infringement claims. Essentially, it acknowledges the rights of users who acted in good faith based on the original patent's scope.

Legal Use & context
This doctrine is primarily used in patent law to assess the validity of reissued patents. It plays a crucial role in determining whether someone who has relied on the original patent claims can continue using, making, or selling the invention after the patent has been broadened. Users can often manage related legal procedures themselves using legal templates from resources like US Legal Forms, especially when dealing with patent reissues.
Key legal elements
Real-world examples
Here are a couple of examples of abatement:
(Hypothetical example) A company manufactures a product based on a patent that describes a specific method. If the patent is later reissued with broader claims that cover additional methods, the company can continue to manufacture its product without facing infringement claims, as it had relied on the original patent's scope.
Relevant laws & statutes
The doctrine of intervening rights is addressed under 35 U.S.C. § 252, which outlines the protections for individuals who have relied on the original patent claims prior to reissue.
