Who under the Indian Patents Law is entitled to apply for a Patent?

In India, a person to be eligible to file an application for a patent should either be the "true and first inventor" of the invention or an assignee or legal representative / heir(s) of the "true and first inventor". An eligibility criterion for persons filing Patent Application in India is provided under1 Section 6 of Patents Act, 1970 (the Act).

Proof of Right to apply for a patent in India:

An assignee of the true and first inventor is eligible to file a patent application for patent in India, provided that the requirement under2 Section 7 of Act to submit the "Proof of Right" document is duly met. Additionally, where an application for patent is made by an assignee, there is a requirement to submit a declaration

mentioning the name of the inventor(s) claiming to be the true and first inventor(s).

Both Sections 6 and 7 of Patents Act, 1970 mention that the person entitled to apply for a patent shall be the true and first inventor of the invention.

First filing:

Considering a hypothetical situation wherein, two genuine inventors working independently and unaware of each other's work, invent on the same concept and involving the same technical advancements on an invention and proceed with filing a patent applications respectively in India. One of the inventors chooses to file a provision application in India immediately when the scope of the invention was ascertainable, whereas, the other inventor chooses to wait for some detailed results and drafting of the specification and files an application for patent at a later date with complete specification and claims. In such a scenario, both the inventors are true and first inventor, however, one of them is the "first filer". This "first filer" in the given facts of the case gets an earlier priority over the subsequent filer, and as per3 Section 13 of the Act, the patent application filed first on an same inventive concept gets the priority over the application filed thereafter. Accordingly, the subsequently filed application, although filed along with the complete specification, is anticipated by the "first filed" application in India. In other words, when two inventors file their respective patent applications on the same inventive concept, as per Section 13 of the Act, the application filed first will get the priority and the subsequently filed application will be considered as anticipated even if the first filed application is not published by the Patent Office at the time of filing of the subsequent application.

In addition to Section 13,4 Section 25 of the Act also has the provision to oppose the application for patent on the ground that the invention was already claimed in a specification which was filed earlier then the patent application which claims the same subject matter and filed later on.

Accordingly, both Section 13 and Section 25 support the concept that the first filer gets the priority and hence a grant of patent over the invention.

"Wrongful obtaining" of the invention:

Considering a hypothetical situation wherein an inventor (the true and first inventor) is deprived of his right to file the application for patent by some other party who learnt about the invention from the actual inventor. This other party, upon learning about the invention from the first inventor under confidentiality restraints, immediately files an application for patent in India in his own name. As per Section 13, this person by being a first-filer would get priority and may get the rights over the patent wrongly appropriated in his own name. In such a scenario, the true and first inventor has the remedy under the law to oppose the application for patent under5 Section 25 of the Act on the ground that the invention was "wrongfully obtained" from the true and first inventor. In such a situation, complete data of research for the invention and other relevant evidences can be submitted to protect the rights in the invention of the true and first inventor. Further, a similar ground is also available for revocation of patent under6 Section 64 of the Act.

Concluding the above discussion, it is established that by filing an application for patent first (as soon as possible), the true and first inventor or his assignee can secure its patent. However, in case any person "wrongfully obtains" an invention from the true and first inventor and manages to file first to wrongly register a patent in his name, such persons (wrongful obtainers) can be checked under the relevant Opposition and Revocation provisions of the Act.
