Design patents have always been favored by patent applicants because of their low investment, low risk and quick effect. The extension of the protection period of design patents will further promote the number of applications for design patents. Then when applying for an appearance patent, there are the following precautions for pictures and models:

1. Pictures or photographs shall not contain any graphics or words that do not constitute the design, such as trademarks, logos, portraits of celebrities, and shall not contain indicator lines, dotted lines, middle lines, size marks, etc.

2. Three-dimensional product pictures should include front view, back view, left view, right view, top view, bottom view and three-dimensional view; Plane product pictures include front view and back view (symmetrical or identical can be omitted);

3. The size of the picture or photograph should be between 3cm× 8cm and 15cm× 22cm;

4. Pictures must be drawn by computer or regular drawing tools;

5, the proportion of each view must be consistent;

6. Time required: It generally takes about 3 to 6 months from application to authorization, and the design patent certificate will be issued within three months after the authorization procedure is completed.

In addition to the above contents, where an applicant for a patent for appearance proposes more than two designs with one application, the serial number of each design shall be marked before the view name of each product using the design. The application of appearance patent directly determines the first impression of the product to the audience and consumers. A good appearance patent can help products open the market faster and get benefits faster.
