Can I apply for a patent design after it expires?

You can apply, and you need to consider the possibility of invalidity.

What information should I prepare for the application?

The application documents include the patent request for the design, pictures or photographs (color pictures or photographs shall be submitted if color protection is required) and a brief description of the design in duplicate. Among them, pictures and photos must not be mixed together.

At the time of application, all kinds of documents shall be downloaded from the official website website of the Intellectual Property Office, or provided and written by the agency, and the relevant documents shall be numbered in the order indicated. No useless words, numbers, boxes, lines, etc. A4 paper shall be used for official documents.

In the process of applying for design patent, pictures or photographs play an extremely important role, which will directly affect the protection scope of design patent. At the time of application, a sufficient number of opinions should be submitted to eliminate the appearance design of the product. If the number of views is insufficient, the shape of the product cannot be determined and it will be rejected. The applicant shall make corrections in time.
