Broadly, there are three types of patent drawings based on the type of patent application:

2.Design Patent Drawing
3.Plant Patent Drawing
1. Utility Patent Drawings
A patent application should enable a “person having ordinary skill in the art” to make and use the disclosed invention. This enablement requirement is satisfied by providing a detailed description of the invention, and in most cases by additionally providing drawings.

3. Plant Patent Drawings
Similar to design patent, reference characters are generally not used in plant patent drawings. The drawings can be in colour or black-and-white; although, colour drawings may be often found in plant patent applications. The colour drawings may be in the form of photographs, or may be made either in permanent water colour or oil.
