The invention should be specific to what the inventor has found; nothing more, and nothing less. If someone does not wish to give the specifics in the patent application, and prefers to claim in a broader way to cover more in the inventive space, unfortunately it will be a mistake. Broader the scope of your patent claims is, more likely your invention will be within the periphery of existing knowledge, nothing to distinguish over the prior art, hence not patentable in the first place.

In the chemical structure patents, especially in the Markush structure patents, though many chemical structures are provided in the application, they all go in the description of the invention, not in the separately defined Drawing section of the patent application.

Generally speaking, a product patent application, a design patent or industrial design application requires more views of Drawings compared to a process or a method patent application. Even in a process or method patent application, if it is possible to explain the invention better, good to provide the drawings in any suitable form.  Software patents and some method patents often require block diagrams / flow charts to explain the invention better.

While you have provided all the details of your invention in words, it’s obviously good not to get an objection from the examiner citing the invention is not sufficiently explained in the form of drawings. Most importantly, whatever you provide at the time of filing your patent application counts toward the total disclosure, and help to keep a smoother priority for you. If the drawing is not up to the mark to explain the invention, the examiner may ask for a replacement of that drawing.

Drawings are the sole of Industrial Designs  and Trademarks

Unlike utility Patents, where the text based claims define the scope of the invention, the scope of a Design right is defined by the drawings only, and Trademark right if is based on a picture, a logo or a label is also defined by its drawings only.

It’s essential to have the Patent, Design, or Trademark drawings convenient enough for a person skilled in the art and/or the examiner to refer, and also it’s required to ensure all the pages are printed in a uniform manner when the patent, Design and Trademark right is granted.  For this, there are rules such as page margin, font size, type of labeling, etc. prescribed by IP offices that our professional illustrators know the best. We help you out there with our know-how of the differing rules of Patent, Design, or Trademark drawings across jurisdictions, combined with the advanced illustration tools that we use.
