Patent Drafting and Filing

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. Patent Drafting is done in two manners - Provisional Patent Drafting and Complete/Non-Provisional Patent Drafting.

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.

Complete/Non-Provisional Patent Drafting is a legal document prepared in techno-legal language and defined by boundaries set by Claims for the invention. Complete Specification is drafted by experienced patent drafters who first identify the novelty aspects of the invention, defines the primary and secondary claims, structural limitations, drawings and details of the drawings and then uses their skills to create an enforceable patent application.

Patent filing marks the beginning of the patent process. It is referred to as the constructive reduction of an invention to practice. Though the process of patent filing is largely procedural, it is an absolutely important step requiring expertise, attention, care and speed. Also, the options possible under patent law, nationally and internationally, necessitate due analysis and a strategic approach to patent filing.
