India Patents

Based in Kolkata, the Indian Patent Office is under the administration of Controller General of Patents, Designs, & Trade Marks (CGPDTM), which is located in Mumbai. The office has 526 Patent Examiners, who are mandated to abide by the Patent’s Act and report to Controllers, who decide on the status of their reports.An India invention patent is valid for 20 years. The 20-year period starts from the application filing date for regular India patent applications, and the filing date for Patent Cooperation Treaty (PCT) applications. The rights of applicants are limited to the territory of India. To file an application outside the territory, the applicant must apply according to the laws of that country or territory, or submit a PCT application. In 2017, the patent office received over 47,854 applications, according to a European Patent Office (EPO) publication.

Besides submitting their India patent applications in person, applicants can also use the e-filing system introduced by the patents office for filing patents and trademarks. In fact, the office is going through a modernization process with the target of achieving greater efficiency. In 2017/2018, the top technical fields where applications were filed included mechanical (24%), computer and electronics (13%), and chemical (13%), according to the EPO.
