What is a Provisional Patent Application?

The patent is an exclusive legal right of the patentee that grants him the legal authority to prohibit others from making or using a patented invention. A provisional application is a brief synopsis disclosing the essence and the nature of the invention. It is the preliminary application that can be filed before filing the complete specification. It explains the patent in brief but not completely. Filing a provisional patent is very useful for inventors as it locks the priority date and secures the invention so that no one else can claim authority over it.
