Patent Drafting


Patent drafting and filing in India is a technical skill. Patent claims are drafted in a way that the patent application will clearly describe the novelty feature, inventive step, and industrial application. A well-drafted patent application ensures that your patent invention is described in a brief and precise manner to help the inventor during the prosecution, grant, management, and maintenance stage.

Basics of patent drafting

A good patent draft should have the following fundamental information- background of the invention, specifications, patent claims, drawings, images, sketches and abstract of the patent. Patent drafting is majorly divided into – Provisional specification drafting and Complete specification drafting. Guidelines to draft the patent application and specification are laid down in the Indian Patent Act.

Statutory Provisions

Section 10 of the Indian Patent Act lays down the guidelines to draft specification: 1.

Drawings should be supplied to the controller for the purpose of specification and that will be deemed to be part of the specification, unless otherwise stated by the controller. 3. If required by the controller, the application has to be further supplemented with a model or sample illustrating the invention and has to be filed before the grant of the patent, but this will not be considered as a part of the specification. 4. The Section also explains the contents of complete specification. 5. The patent claim drafting should in particular describe the invention n and its usage guidelines. Note: The disclosure or the draft should disclose the best method of performing the invention which is known to the application or end with a clam defining the scope of the invention and shall be accompanied with an abstract to provide technical information.

Provisional specification

A Provisional Patent Specification is a preliminary application before filing for the final patent. It elucidates the invention in a comprehensive manner but not completely. It is not mandatory but usually filed before the Application for complete specification. The specification of the patent is published in the public domain once it is applied for a patent grant. Thus, it is pertinent to be cautious while drafting the claims and details without any ambiguity, including the language and structure constructed in the specification.
