  • It clarifies owner’s claims (if any) if in any case get mistakenly caught for patent infringement.
  • It can also benefit patent holders while damaging negotiation or settlement.
  • It brings more sense and unambiguity to the application, making it less secured from potential infringers.

Technical Specifications for Better Drawings

Better drawings can only be drawn if the draftsperson understands the specifications according to the preferences of the inventor.  Ideally, the draftsperson has to meet the following technical specifications:

  • Submission medium: Drawings are allowed to be submitted from paper to digital media, according to its shape and size specifications. There are a lot of specifications, such as the size, thickness, flexibility of sheets, etc. that all has to be followed.
  • Drawing specifications: It meet be in the accordance with the territorial, USPTO (for U.S. filers), and the PCT (for international applications) rules. It must also follow specifications relating to the shades, color, letter size, paper size, shadow, thickness of line, etc. Drawings must also be clear, specific, unique, and well-explained.
  • Mode of creation: The quality of the drawing depends upon the skill of the draftsperson. It is better and reliable to use CADD files, which save efforts of the draftsperson from creating images from the scratch. It is easier to use a software for creating drawings because you just needs to feed the specifications and drawings can be created using drag and drop, it can be modified, duplicated, and reused.
  • Severity level: Drawings can be formal and informal in nature. Formal drawings are main drawings that depict the actual structure/working of the invention through all its labelling in black and white ink. While informal drawings are the ones which can even be avoided or does not bear equivalent importance within the patent application. Also, sometimes when formal images are converted into low-quality images, they are termed as informal images, since they lose integrity, quality and detail. When the patent office requests that the applicant submit formal drawings, often the only existing reference material is a low quality copy of the informal drawing.
  • Special case for PCT applications: PCT specifically states that drawings must only be enclosed wherever necessary for the understanding of the invention. Drawings are required especially for mechanical and electrical inventions; whereas for inventions from chemical industry, there will be no benefit of representing chemicals through drawings.

  • Drawing Specifications for Design Patents: When it comes to design patents, drawings are basic and the must to be used. Drawings in design patents constitute the entire visual disclosure of the claim. The filers filing in accordance with the USPTO, requires all surfaces of drawings to be appropriately and adequately shaded. They do not include broken lines. While surface shading and broken lines are acceptable under the PCT. Sometimes when the design is difficult to be represented through line art, photographs have to be submitted instead. In cases where photographs are not allowed and an applicant is requested to supply regulation black-and-white drawings, the applicant will not be allowed to correct any inconsistencies in the drawings once they have been submitted, unless that can be done without adding new matter.
