Patent classification:
Patents are divided into valid patents and invalid patents according to the ownership of the holder.
1. Valid patent
A valid patent generally refers to a patent that is still valid after the patent application is authorized. To make a patent valid, first of all, the patent right is still within the legal protection period. In addition, the patentee needs to pay the annual fee as required.
2. Expired patent
After the patent application is authorized, the patent right is lost or is used by any individual because the statutory protection period has expired or because the patentee failed to pay the annual patent fee in time. Or after the unit requests to declare the patent invalid and the Patent Reexamination Board determines and declares it invalid and loses the patent right, it is called an invalid patent. An expired patent no longer binds the use of the technology involved.
