A patent is an exclusive legal right of the owner of the same (patentee) which grants him/her the legal authority to prohibit others from making or using a patented invention. A provisional patent application is a brief synopsis disclosing the essence and nature of the invention, which is a kind of preliminary application that an inventor can file before filing the complete patent application. Even it explains the patent in brief; filing a provisional patent is very useful for the inventor as it locks the priority date and secures the invention, so that no one else can claim authority over it. The inventor will be provided a time period of 12 months from the date of application to file the final patent draft called Complete Patent Specification.
