Appearance patents require drawings.
The abstract drawings should be the drawings that best illustrate the main technical features of the technical solution of the invention or utility model as the abstract drawings (if the invention does not have description drawings, it is not necessary to have abstract drawings). The drawing attached to the abstract should be one of the drawings included in the description. If the applicant fails to submit a drawing for the abstract, the examiner may notify the applicant to make corrections or designate one ex officio. In addition, the abstract drawings, like the abstract, are only used for patent information retrieval and have no legal effect.
