When we wish to attract prospective licensee: One of the import reasons for inventing something is to monetize it in future. There are many ways of monetizing a patent, still the most obvious one is to license it to a third party and then comes the importance of attracting the eye-balls of licensee. Patent drawings contain reference numerals those are used by the patent attorneys for detailed description. These reference numerals are used for drawing the attention of the prospective licensee and allowing him to easily envision the final product when it will be launched and sold to the end user.

Though, a patent drawing may not help us directly in a patent litigation still it would help in making things clear during litigation. If a drawing is present we can describe our claims in a much more firm manner without having a need to read hundreds and thousands of texts in an application.
