Patent Filing Process

The patent process generally refers to rules related to the process of forming and executing the patent application in a particular jurisdiction. A patent application can be registered by a person who claims to be the true and first innovator of the invention, or it may be filed by the attorney of the true and first innovator. India recognizes two types of patent forms.

What is the Procedure to Register a Patent in India?

An assignee- company, firms, government to any other legal person may file the application provided the first and true inventor has assigned the invention to the assignee. The assignee is required to file the assignment deed along with the application or within six months from the date of filing the application. Depending upon the territorial jurisdiction, the application must be filed in any of the appropriate patent offices located in New Delhi, Kolkata, Mumbai, and Chennai. The application should be filed either in Hindi or English. The manner of writing, specification of the paper, margins, a signature should be as prescribed in law. The patent strategy in India can be comprehensively partitioned into the accompanying stages:- 

1. Filing 
2. Request for Examination
3. Publication
4. Examination
5. Opposition - Pre Grant and Post Grant
6. Registration and Renewal fee payment

Applications may be filed directly at Indian Patent Office or as a national phase application under PCT or as a conventional application claiming priority of the first foreign application. A convention application can be filed within twelve months after filing the first application in any member country of the Paris Convention. Even where two or more applications are filed relating to cognate inventions, a single convention application can be filed covering all of them. Convention applications can be filed only with complete specifications and not provisional specifications.
