Explanation:

Patent rights last for about a limited period of time, as well as the right to file a lawsuit on other sides for infringement of the patent is centered on that time.

Inventors and other patent proprietors may therefore choose to measure and evaluate their patent's expiry date.

It will mostly rely heavily on the date of filing of your patent application, and also the sort of patent they obtained.

Patents are defined as utility patents, patents on designs or patents on plants.

Patent protection for utility patents, which are the most common type of patent, and which EasyOpen Inc is part of, lasts 20 years after the patent application's filing date.
