Patent registration can be done online and offline. For offline registration, there are four branches of Patent Registration offices in India, viz., Kolkata, Delhi, Chennai, and Mumbai. Every office has a different jurisdiction for registration which is based on the inventors domicile or place of business or the original place where the invention was done.
The cost for patent registration depends on the number of pages and claims in the patent application. The minimum cost is INR 8000, for up to 30 pages and 10 claims. There is additional cost for each page after that.
The Official Controller General of Patents, Designs, and Trade Marks in the Indian Patent Office is the whole and sole authority for granting patents in India.
Patent registration is quite a long process. It takes 18 months to have the application published in the Official Gazette. That can be accelerated by filing a request for early publication. However, after this, a request for examination is to be made and that’s upon the applicant. The applicant can delay making such request for as long as 4years. Once the request for examination is filed, it takes at least 2 years to examine the application. So, it’s a considerably long procedure and can take anywhere between three to seven years based on when the applications and requests are filed.
A patent is valid for 20 years after registration. Once expired, the applicant can make further application for the renewal of the patent.
