Non- Provisional Patent Drafting

A non-provisional patent draft is a techno-legal document describing the invention in-depth and discloses the best method of carrying out the invention. Thus, also known as a complete patent application.

A provisional patent application is not examined, so its claims not get rejected in an office action. Depending on what was the problem that is being referred to as a rejection, a provisional application that fixes the problem might be subsequently filed with a later filing date

Provisional Patent Application

As per the patent law, a provisional application is a legal document filed in the Indian Patent Office or any other patent office to establish an early filing date and allows the inventor to file a patent application without a formal patent claim, oath or declaration, or any information disclosure (prior art) statement.
