In such a case, the application must be accompanied by proof of authority to make the application with a declaration that the person making such claim is the first and true inventor of the invention. An application for a patent may also be filed by the legal representative of the deceased person who was entitled to such patent before his death.

Different Types of Applications Filed Under The Indian Patents Act, 1970

Different Types of Applications Filed Under The Indian Patents Act, 1970 are as follows: –

  1. Provisional Application: – A provisional patent application (PPA) is a document issued by Patent and Trademark Office to help protect a new invention from being copied during the 12-month period before a formal patent application is filed. Its purpose is to give the inventor time to pitch the idea, test its commercial viability, or refine a product before committing to the expensive and time-intensive process of a formal application;
  2. Ordinary or Non-Provisional Application: – An application filed at the Patent Office without claiming the priority of an application made in a convention country or without reference to any other application under process at the office is called a general application. A typical application should be accompanied by complete specifications and claims;
  3. Convention Application: – A Convention application is filed to claim a priority date on the basis of a similar or substantially similar application filed in any of the Convention countries. The applicant is required to file an application with the Indian Patent Office within one year from the date of initial filing of a similar application in the Convention country. As per section 135 of the Act, a Convention application is an application made under the Act within 12 months from the date on which the application for a patent is made in respect of an invention in a Convention country (also known as basic application);
  4. International Application: – An international application is an application that is filed in accordance with the Patent Cooperation Treaty. Such applications provide patent protection in a large number of countries through a single application rather than filing multiple regional applications. Such application is treated as an application for a patent under the Act if it is filed before the Controller in India. The filing date of such application is considered the international filing date under the Patent Cooperation Treaty. The complete specifications include description, images, abstracts and claims filed with the International Application under the Act;
  5. Divisional Application: – Section 16 of the Act deals with the division of an application. Such an application may be settled either at the will of the applicant prior to the grant of the patent or on the demand of the Controller, the objection raised by him on the ground that the claims of the complete specification pertain to more than one invention. In such case, the applicant may file further application in respect of the invention mentioned in the provisional or complete specification, as the case may be, along with the application already mentioned;
  6. PCT National Phase Application: – A national stage application is filed in each country seeking protection. The national stage application must be filed within 30 or 31 months from the priority date or the international filing date, whichever is earlier. It is one-time submission to apply for a patent through Patent Cooperation Treaty (PCT) member states. This streamlined process provides patent protection while adhering to the individual needs of each nation. It is dated prior to the original date of filing.

What are the steps involved in Filing Patent Application in India?

The steps involved in a Fliling Patent Application in India are as follows: –

Procedure For Filing Patent Application
  1. Conceiving your Invention: – This is the first step for an inventor who wants to proceed with his invention. It is important to collect as much information as possible. Some of the relevant questions the inventor should consider are: What is the scope of the invention, what are its advantages, how will it help improve already existing solutions? Not all inventions are patentable subjects.
    Section 3 of the Patent Act provides for subjects which are not patentable. Therefore, while conceiving, it should be clear to the inventor that the invention does not fall under any category that is not patentable.
  2. Patent Search and Drafting: – After obtaining clarity on the invention, the inventor must conduct a patent qualification search. This is important as it will help in understanding whether the invention is novel or not. All inventions must meet the novelty criteria under the Patent Act. Patent qualification opinion may be scrutinized by conducting a comprehensive search and creating a patent eligibility report.
    The patent qualification search identifies the closest possible prior art (known to the public) related to the invention and, based on the results obtained, provides an opinion that may be positive, negative or neutral about the patentability of that invention. Still, one can choose to file an application directly, but a patent qualification search is highly recommended.
    The next step is effective drafting of the patent application. The application consists of various parts like claim, background, description, drawing (if any), abstract and summary. All such parts must be carefully prepared to provide effective disclosure of the invention. It is advised that utmost care and accuracy should be exercised while drafting the application.

There is no special requirement from the applicant for publication. If the applicant does not wish to wait until the end of 18 months, an early publication request can be made by filing Form 9 along with the prescribed fee.

The general request must be filed within 48 months from the date of filing the application under Form 18. On such request, the controller makes an application to a patent examiner who examines it with various patent eligibility criteria, which are novelty, non-obvious or inventive step, and capable of industrial applicability to provide First Test Report (FER) to the applicant.
    The applicant can also file a request for expeditious scrutiny of the application under Form 18A. Rule 24C- An applicant may make a request for expedited examination in Form 18A, together with the fee specified in the First Schedule, by electronic transmission duly certified within the period prescribed in Rule 24B, on any of the following grounds, namely: –
