Utility Patent Drawing Requirements

Patent drawings are an essential part of a patent application. Therefore, an applicant needs to add several patent drawings in their patent application. Moreover, there are several views of an invention. Each view tells about a new appearance and functionality of the invention. As a result, patent drawings are easier to understand. Without a single utility patent drawing, a utility patent application is unacceptable. Therefore, it becomes necessary for applicants to know about the Utility Patent Drawing Requirements. The following are the utility patent drawing requirements.

  • Black and white drawings are preferred. However, in some cases, applicants may use colour drawings.
  • Applicants should include the title of the invention, inventor’s name, and application number, or docket number for identification.
  • Each drawing sheet must include margins (at least)
    • Top – 2.5 cm,
    • Left – 2.5 cm,
    • Right – 1.5 cm, and
    • Bottom – 1 cm.
  • If an invention requires chemical or mathematical formulae, tables, and waveforms to be displayed, an applicant may use them.
  • Drawings should be large enough to be reproduced in two-third of original drawing size.
  • No hole should be present in drawing sheets.   

The USPTO has an extensive list of drawing rules. These drawing rules act as utility patent drawing requirements.
