  1. Black and white drawings – Black and white drawings are the most preferred illustrations. You can make these drawings using a ruler, a pen, and Indian ink. However, you should attempt your drawings in pencil before producing the final draft.
  2. Colour drawingsUSPTO rarely allows the use of colour drawings. They require a fee, a statement highlighting the need for color drawings, and a petition to the USPTO.
  3. Photographs – Photographs are the least-used medium for patent applications. They are only accepted when a drawing is insufficient to explain the invention. This usually happens in the case of biological patents such as animals, plants, or cell cultures.

Yet another reason to avoid free patent drawing software is that you may need the help of a seasoned draftsman/patent illustrator. Hiring such experts can get expensive. However, if you choose to try your hand at the software, keep in mind that most programs are expensive, and they generally require additional aids such as a digital camera or scanner.

If you are apprehensive about creating a patent drawing yourself, the USPTO website is a useful resource. Here you can look at sample drawings that range from amateur to professional. This should reassure you that your invention is more important than the quality of the drawing.
