Illustrate your patent drawings professionally for faster grant!

You have the next great idea that could be monetized and you are preparing your meticulously drafted patent application claiming the invention with appropriate drawings. You are concerned with submitting a draft application complying with the patent office guidelines to avoid delays and to get quick approvals.

Patent drawings or patent illustrations are graphical representations of an inventive concept submitted by the patent applicant. The USPTO(United States Patent and Trademark Office) requires the applicant to furnish the finest available illustrations wherever the uniqueness of the invention can be explained better through drawings. Good illustrations while making the examination process easier are also effective in showcasing the invention to potential licensees or buyers of the technology and get your invention to market faster.

The Patent Office demands that the applicant submit at least one drawing for a patent unless the patent filed is a chemical compound. If a patent applicant unintentionally misses out an illustration where it is supposed to have been submitted, then the commissioner can request the applicant to submit the drawings within two months from the time of request. Drawings submitted after the filing date will neither be considered to offset the missing information, nor would they be accepted as an addendum to the original disclosure.

Design and utility patent drawings must be rendered using black ink: India ink or equivalent. Patent offices usually discourage patent applicants rendering illustrations in color unless a valid substantiation is put forth explaining why a color drawing is required to illustrate the invention better. Color drawings are not accepted in international applications as well as for patents filed through the electronic filing system.

Utility Patents

Utility patent drawings typically show parts of a device, assemblies, electric circuits, components of a system, or flow chart of a process. The parts must be called out using leader lines and numerals. Text labelling of parts is not permitted, except within a block diagram or a flow chart. Complex mechanical parts or assemblies must be effectively illustrated using isometric or perspective views, sectional views or cut-aways. All the features of the claimed invention should be clearly illustrated, and small parts must be labeled in sufficient detail to support the claims.

Scale used for the drawings must be in such a way that it does not look crowded when it is re-created at 2/3 size. Shading can be used to help understanding the structure or shape of the invention.

Design Patents

Design patents are used to depict original and ornamental design embodied or applied to an article of manufacture.

The design patent drawing’s primary purpose is to aid the patent examiner to understand the appearance and aesthetics of the product. Special artistic skills may be called for to show the shape, contour and texture of the invention. Design patents are mostly used to protect new designs of jewellery, furniture, containers of beverages, processed food and computer icons. Reference numbers are not needed in design drawings. Design patents are granted for a period of 14 years, during which the inventor has exclusive commercial rights over the design.

Self-help or Professional help?

Patent offices apply specific criteria concerning the technical details of drawings they accept, but attention must be paid to more than just meeting those requirements. A patent applicant’s safest option is to use the services of a professional draftsperson specialized in technical patent drawings and with thorough knowledge of rules of the various patent offices. Many patent offices now accept drawings submitted on anything from paper to digital media, but specifications on shape, size and form often vary. Drawings must meet the requirements of the country where the patent is filed such as the U.S. Patent and Trademark Office(USPTO) for filings in the U.S, or the Patent Cooperation Treaty(PCT) for international applications.
