Legal Definitions - broadened reissue patent

A broadened reissue patent is a type of patent that is issued again with broader claims than the original surrendered patent. This means that the patent holder can now claim more rights to their invention than they could before.

For example, if an inventor originally filed for a patent on a new type of car engine, but later realized that they could also claim rights to a new type of fuel injection system, they could file for a broadened reissue patent to include this new claim.

This type of patent is only granted under certain circumstances, and the reissue application must be filed within two years of the original patent grant. It is important to note that a broadened reissue patent may affect the rights of others who may have been using or developing similar technology.
