Why Patent applications must include Patent Drawings.

In the same way that textual representation is less effective than visual representation, patent applications also benefit from visual representation. It is far more beneficial to submit patent drawings or illustrations along with the written description to the patent examiner than simply the written description. They walk the patent examiner through the invention and describe it in detail, which increases the likelihood that the patent will be approved.

Patent illustrations may convey an innovation better than any text and are worth a thousand words. They focus on the specifics of the idea and how it operates, making it simple to understand how the technology works.

However, patent offices like the USPTO and EPO have yet to make it a requirement. Therefore, applicants are free to file a patent application without one. A patent drawing is one of the most crucial components of a patent application. It is recommended that every patent application include a picture to maximise the likelihood that the patent will be granted.
