Will the applied patent fail if it is not put into production for three years?

There is no such statement in the Patent Law and the Regulations for the Implementation of Patents. On the contrary, there is the second paragraph of Article 49: If a registered trademark becomes the common name of the goods it has approved for use or is not used for three consecutive years without justifiable reasons, any unit or individual may apply to the Trademark Office for cancellation of the registered trademark. The Trademark Office shall make a decision within nine months from the date of receiving the application. There are special circumstances that need to be extended, which can be extended for three months with the approval of the administrative department for industry and commerce of the State Council. If you are interested in a trademark, you can always check the progress of the next trademark, check the status of the trademark, and monitor the trademark. Invalid patent means termination of patent right. 1, invalid; 2. Failing to pay the annual patent fee within the specified time; 3. The term of patent protection expires.
