Patent Drawings
According to a common expression, “a drawing is worth a thousand words”. Patent drawings should be done with this principle in mind. Patent are often searched and identified by their cover-page drawing. Therefore, the cover-page drawing should explain the invention at a glance. All the other drawings should also be self-explanatory at a glance. The quality of patent drawings reflects the quality of the invention, and the skills of the inventor. An Applicant should also consider that a patent is published “forever”. After a patent is granted, it is not possible to replace the drawings with better ones. For example, patents since 1790 are still visible in the US Patent Database. Patents since 1920 are visible at the Canadian Intellectual Property Office. Therefore, your great-great-grand-children will be able to see your invention. Your patent should reflect your pride. Quality drawings will do that.
