Under what circumstances is the appearance patent invalid?

Legal analysis: 1. The application for a patent for design that has been granted a patent right is an existing design, and there is no obvious difference or conflict with the prior legal right;

2. The application for a patent for design that has been granted a patent right is not beautiful or is not a new design;

3. The patented design patent does not clearly show the product to be protected;

Where a design in any of the above circumstances has not been patented, it may be declared invalid if it has been patented.

Legal basis: Article 45 of the Patent Law of People's Republic of China (PRC). Since the date when the patent administrative department of the State Council announced the grant of the patent right, any unit or individual may request the Patent Reexamination Board to declare the patent right invalid if it considers that the grant of the patent right is not in conformity with the relevant provisions of this Law.
