Many people ask that why does the patent application required drawings? I am an explained with an example when the inventor has no idea about the patent drawings might prefer the photograph of the product drawings to be submitted to the patent office and the patent drawings should be easily explained about the product with is a description and by photograph.
Further to strengthen an invention application the drawings will be submitted should be more clear and more accurate which also aids in describing the claims. In order to patent drawings should not be sketched just meet the requirements of the invention and disclose the inventions. This requires professionally skilled patent draftsmen who have the knowledge not only of the technical terms but also what the patent office actually demands in the drawings.
