The Patent Office provides the facility to file a Patent Application online from the native place of the applicant or agent of the applicant through e-filing at the below link:

Alternatively, one can file patent application offline in hard copies to the patent offices located at Delhi, Kolkata, Mumbai and Chennai. But the patent office charges 10% additional fee if the applications are filed offline.

The patent application has to be filed in the appropriate office based on your/your company location. The table below provides the addresses of the patent offices in India and their respective territorial jurisdiction.

The patent application has to be written in specified manner before filing the patent application in Indian patent office. In case your invention is maturing stage, you have the option to file the provisional patent application, and after that you can file the complete patent specification within 12 months from the date of filing of provisional application.

After filing your patent application, the patent application is published after 18 months from the date of first filing.

During the patent prosecution, the examiner submits the examination report, in which he may cite the relevant prior art/ patent, which might negate the claimed invention. The inventor has to analyze the report to respond the examination report along with providing proper reasoning about his invention for patentable. After meeting the objection raised by the examiner, the application would be placed order for grant and the grant will be notified in Patent journal.
