Why You Need Patent Drawings For Your Patent Application

Oct 18th 2015 at 6:25 AM

Patent drawings or illustrations are visual representations of present descriptions submitted with patent applications. The primary purpose of patent drawings is to help in clear understanding of the invention and these drawings may also include illustration of several views, embodiments, stages and flow charts, chemical equations and even photographs of the invention. Depending upon the laws of various jurisdictions patent illustration may be required to conform to a particular form but they must preferably depict every single feature of the invention those are mentioned in the patent claim. Inclusion of drawing or photographs is not mandatory to be submitted with patent applications under many jurisdictions but if you are going to file one – it is always a better idea to include drawings in the application.

Patent drawings contain reference numerals those are used by the patent attorneys for detailed description, but it must also be kept in mind that detailed description means a description of what is shown in the figures. The reference numerals are used for drawing the attention of the prospective licensee and allowing him to easily envision the final product as it will be made available to the consumers. With patent drawing one can also show an exploding view of the product showing how the different parts and pieces fit together – that also allows the patent attorney to describe step by step development of the invention – which is also a requirement for any patent application process.

As a requirement a patent applicant needs to furnish at least one patent drawing if the invention can be represented by means of drawing. According to experts even if it is not technically required, applicants should submit at least one patent illustration along with their application. The only cases when a patent drawing might not be required are inventions related with methods, compositions or chemical compounds. It is very much true that a detailed drawing is worth more than a thousand words if not more and if the applicant accidentally misses something to mention in the written disclosure – there is a high chance that the drawing will save him in the long run provided that it is prepared by a good patent illustrator and detailed enough to convey nuanced information regarding the invention. That is also the reason having a professional patent illustrator is important and multiple detailed professional drawings are certainly an excellent and effective way of broadening the scope of the application. This is a major benefit of hiring a professional and the investment is certainly worth it.

It is very much true that all patent drawings require depicting every single feature of the invention those are specified in the claim and it is the patent office that specifies the size of the drawing sheet on which the illustration will be made along with the margins, the type of paper and a number of other hyper-technical details. But one must also know that none of these rules will apply to provisional patent drawings, for it primarily focuses upon demonstrating the entirety of invention.
