What is the procedure for registering a patent in India

Understanding Patents and Patentability Criteria

A patent is an exclusive right granted by the government to an inventor for a new, useful, and non-obvious invention. In India, patents are governed by the Patents Act, 1970 and the Patents Rules, 2003. The patent system aims to encourage innovation by granting inventors a monopoly over their inventions for a limited period (20 years) in exchange for public disclosure of the invention. To be patentable, an invention must satisfy three criteria: novelty (the invention must be new and not anticipated by prior art), inventive step or non-obviousness (the invention must not be obvious to a person skilled in the art), and industrial applicability (the invention must be capable of being made or used in an industry).

Certain subject matters are excluded from patentability, including discoveries, scientific theories, mathematical methods, business methods, computer programs per se, and methods of medical treatment. Vidhi Legal Services assists inventors and companies in assessing patentability and preparing robust patent applications.

Types of Patent Applications in India

The Indian patent system recognizes several types of patent applications. An ordinary application is filed directly with the Indian Patent Office without any priority claim. A convention application is filed within 12 months of filing a complete application in a convention country, claiming priority from the first application. A PCT (Patent Cooperation Treaty) international application is filed through the PCT system, which allows applicants to seek patent protection in multiple countries through a single application. A PCT national phase application is filed in India within 31 months of the priority date of a PCT application.

A divisional application is filed when a patent application claims more than one invention, and the applicant divides the application into multiple applications. A patent of addition is filed for an improvement or modification of an invention already patented by the applicant. Each type has specific filing requirements, timelines, and fee structures. Vidhi Legal Services advises on the most appropriate type of patent application for each invention.

Procedure for Filing a Patent Application

The patent application process in India involves several stages. The first step is to file a provisional specification, which provides an early priority date and allows the applicant 12 months to develop the invention further. A complete specification must be filed within 12 months of the provisional application, containing a detailed description, claims, drawings, and abstract. The application is published in the Patent Office Journal after 18 months from the filing date. The applicant must file a request for examination within 48 months of the filing date.

The Patent Office examines the application and issues a First Examination Report (FER) listing objections. The applicant must respond to the FER within 6 months, addressing the objections through amendments or arguments. If the objections are resolved, the patent is granted. The patent is valid for 20 years from the filing date, subject to payment of renewal fees. Vidhi Legal Services manages the entire patent filing process, from specification drafting to grant.

Patent Examination and Opposition Proceedings

Patent examination is conducted by the Patent Office to determine whether the invention meets the patentability criteria. The examiner searches prior art databases to identify any anticipation of the invention and examines the application for compliance with legal requirements. The FER lists all objections, which may relate to lack of novelty, obviousness, insufficient disclosure, or defective claims. The applicant must respond with arguments and amendments to overcome the objections. If the examiner is satisfied, the patent is granted.

If not, a hearing is scheduled. After grant, the patent may be challenged through pre-grant opposition (filed before grant by any person) or post-grant opposition (filed within one year of grant by any interested party). Opposition grounds include lack of novelty, obviousness, insufficient disclosure, or that the patent was obtained through misrepresentation. Vidhi Legal Services provides representation in patent examination and opposition proceedings.

Patent Renewal and Maintenance

A granted patent must be maintained through payment of renewal fees. The first renewal fee is payable after the second year from the date of patent grant, and subsequent fees are payable annually. The renewal fee increases progressively with the age of the patent, with higher fees for the later years of the patent term. If the renewal fee is not paid, the patent lapses and cannot be enforced. A lapsed patent can be restored within 18 months by filing a restoration application with the Patent Office.

The patentee must also record all assignments, licenses, and other transactions affecting the patent with the Patent Office. The patentee must mark the patented product with the patent number to indicate that the product is patented. Vidhi Legal Services provides patent portfolio management services, including renewal fee tracking, maintenance, and recordal of transactions.

Enforcement of Patent Rights

Patent infringement occurs when a person makes, uses, sells, or imports a patented product or process without the patentee's consent. The patentee can file a patent infringement suit in the appropriate High Court or District Court having jurisdiction. The court can grant remedies including injunctions (temporary or permanent), damages or account of profits, and seizure of infringing goods. The burden of proof in patent infringement cases lies with the patentee, who must establish that the alleged infringement falls within the scope of the claims.

For process patents, the burden shifts to the alleged infringer to prove that the process used is different from the patented process. The court may also order the defendant to disclose their process. Defenses to infringement include invalidity of the patent, experimental use, and prior use. Vidhi Legal Services provides representation in patent infringement litigation and patent enforcement matters.
