Patented products can be sold. Just selling goods does not constitute patent infringement. It is illegal to use the patent to produce and sell products without authorization.
The patentee change process is as follows:
1. If the right of the applicant or patentee is transferred due to the dispute over the ownership of the right, and the inventor is changed due to the dispute over the qualification, if the dispute is resolved through consultation, a right transfer agreement signed or sealed by all parties shall be submitted; If the dispute is determined by a judgment of the people's court, it shall be submitted to a legally effective judgment of the people's court. After receiving the written judgment, the Patent Office shall notify other parties to inquire whether to file an appeal. If there is no reply or no appeal within the prescribed time limit (two months), the judgment will take legal effect; If a party files an appeal, it shall issue a notice of acceptance of the appeal, and the original judgment of the people's court will never take legal effect.
2. Where the patent applicant or patentee requests to change the patent applicant or patentee because of the right transfer or gift, the original or notarized copy of the transfer or gift contract must be submitted; When a contract is concluded by a legal person, it must be signed or sealed by the legal representative or authorized person, and stamped with the legal person's official seal or special seal for the contract; Submit notarized documents when necessary. When concluding a contract, a citizen shall sign or seal it; Submit notarized documents when necessary. Where there is more than one patent applicant or patentee, the certification materials that all the obligees agree to transfer or give shall be submitted.
To sum up, after the design patent is granted, no unit or individual may exploit its patent without the permission of the patentee, that is, it may not manufacture, promise to sell, sell or import its patented products for production and business purposes. Therefore, it is an infringement to sell patented products without the permission of the patentee.
