How to Identify Professional Patent Illustrators

A patent illustrator is an artist who can create a sketch to express an idea or concept with his imagination and conceptual knowledge. Since drawings are a critical component of a patent application, patent illustrators help applicants to create an effective and clear illustration of their invention to strengthen the application. However, one must carefully identify a professional illustrator who can carry out these tasks effectively. The following article explains the parameters based on which businesses can identify these professionals. But first, let’s understand the importance of a professional patent illustrator and the patent drawing rules he must adhere to.

The Need for Professional Patent Illustrators

There are several patent drawing rules stipulated by patent offices. So, inventors must ensure that the patent illustrator/company that they are commissioning the drawing to is adequately experienced. There are different patent drawing rules and regulations which they should know before filing a patent in any jurisdiction. Some of them are:

  • The size of the paper shall be A4, viz. 210 mm x 297 mm or 8 1/2 by 11 inches ( it is de-facto North-American standard).
  • The illustrator must ensure a minimum margin of 2 cm at the top, bottom, and sides of each sheet, and one of 2.5 cm on the left side of every sheet.
  • Non-script type font should be used for the text. For example, one can use fonts like Arial, Times Roman, or Courier. Similarly, the font size should preferably be 12. The lettering style should have capital letters which must be at least 0.3175 cm (0.125 inches) high. But it shouldn’t be smaller than 0.21 cm.

Apart from these, there are several other patent drawing rules which illustrators must consider while filing a patent. Applicants can file a non-provisional patent application without illustrations but it is not recommended. This is because a professional patent illustrator can reduce the overall costs of patent filing and minimizes the possibility of receiving an office action.
