Patent Drafting

Patent drafting is techno-legal content writing of an invention to be filed in patent office. The patent drafting follows guidelines laid out by the patent offices and differs from country to other. After assuring that the invention is patent-able, the inventor can proceed for drafting the patent in Indian patent format. Patent Draft format is decided on the basis of content and stage of the invention/innovation – Provisional Patent Drafting and Complete/Non-Provisional Patent Drafting.



Provisional (Idea) Patent Drafting

  1. What is a Provisional Patent and why it is done?

– Provisional patent is a provisional or non-permanent right given to an inventor for establish a priority for an idea or a concept with very less or incomplete technical information. Provisional Patent Drafting and filing is done to establish a priority date for an idea or in other words a patent for an idea is applied as provisional patent. Provisional Patent as the word suggests is not a final legal documentation and is suggested to file only if the inventor has incomplete information or just an idea and intend to get some time period to develop the product or gain complete information of the invention. Provisional patent drafting has to be converted into a complete/non-provisional patent within a period of 12 months otherwise the patent priority lapses.

Unlike non-provisional patent applications, there are no specific requirements or set guidelines for what has to be included in a Provisional Patent Application. Meditate on that. The nature of your idea — like whether it’s a simple consumer product or a game-changing innovation — has to be taken into account. If it’s the former, you may be able to generate income without ever needing to file a non-provisional application. If it’s the latter, you will need a wall of patents to keep others at bay.
