This article is written by Vivek Maurya from ICFAI Law University, Dehradun. This article describes the stages of time taken by different countries to grant a patent license.


The time taken by the patent offices to grant a patent is generally the time for the inspection, modification, and for any objections to determine that the patent is new and first. In most countries, the patent procedure starts with filling an application for the invention with the prescribed fees and ends with granting patent rights, which exclude others from making or selling that invention for a limited time.


The Patents Act 1970, along with the Patents Rules 1972, came into force on 20 April 1972, replacing the Indian Patents and Designs Act, 1911. The Patent Act was largely based on the recommendations of the Iyengar Committee Report headed by Justice N Rajagopal Iyengar. One of the recommendations was to allow the processing of patents only in respect of inventions relating to drugs, food, and chemicals.

Later, India became a signatory to several international arrangements aimed at strengthening its patent law and coming into the league with the modern world. An important step towards achieving this objective was to become a member of the Trade-Related Intellectual Property Rights (TRIPS). Significantly, India also became a signatory to the Paris Convention and the Patent Cooperation Treaty on 7 December 1998, and then on 17 December 2001 the Budapest Treaty.

Meaning of a patent

A patent is an exclusive right to a product or process that typically provides a new way of doing something or a new technical solution to a problem. To obtain a patent, technical information about the invention must be disclosed to the public in the patent application.

The patent owner may permit or license other parties to use the invention on mutually agreed terms. The owner can also sell the rights to the invention to someone else, who will then become the new owner of the patent. Once a patent expires, the protection expires, and an invention enters the public domain, that is anyone can commercially use the invention without infringing the patent.

What inventions are patentable 

To determine whether the invention relates to something that can be patented, it should not fall within the ambit of Section 3 and Section 4 of the Patent Act. Section 3 and 4 of the Patent Act lists non-patentable materials. If the invention does not fall within the scope of any of the provisions of Section 3 or 4, it means that it is subject to patentability. Legal criteria for the patent of an invention:

  1. Novelty

Innovation is an important criterion in determining the patent potential of an invention. Section 2(1)(l) of the Patent Act defines innovation or innovation as “any invention or technology that is not intended to be published in any document or publication in the country or elsewhere in the world before the filing of the patent application with full specification, that is the subject matter has not fallen into the public domain or is not a part of state of art”. 

Simply putting the need for innovation is fundamental for patents and it should never be published in any public domain.

  1. Inventive step or non-obviousness

According to Section 2(1)(j) of the Patents Act, the innovation phase is defined as “a feature of an invention that is technologically advanced compared to current knowledge or financial significance or both and makes the invention clear to the skilled person”. This means that innovation should not be obvious to a person who specializes in the same field of innovation. It should be invented and not obvious to a person who specializes in the same field.

  1. Capable of industrial application

An industrial application is defined under Section 2(1)(ac) of the Patents Act as an “invention capable of being manufactured or used in any industry”. This means that the invention will not be abstract. It must be applied in any industry, i.e. there must be a practical purpose to the invention to obtain a patent.

What inventions are non-patentable 

Despite the satisfaction of testing for any innovation, novelty, use, and lack of clarity, it cannot be patented if it falls within any of the criteria under Sections 3 and 4. Section 3 of the Indian Patent Act specifically mentions sixteen exemptions from which a patent cannot be obtained in India.

  1. A patent must not be a petty invention or contrary to established natural laws.
  2. The invention of the scientific principle or the formulation of the abstract principle or the invention of any living thing or creature that occurs in nature is not patented.
  3. Discovering a new form of a known substance that increases the efficiency of that substance or the discovery of a new property or a new use or known process for a known substance, machine, or equipment will not be patented if such a process leads to new production or at least hires a new reactant.
  4. The alignment or reorganization or duplication of known devices, each operating independently of the other in a known way is excluded from the patent.
  5. The farming or horticultural method, for example, the actual process of cultivating a new type of soil or wheat cannot be patented.
  6. Medicine, surgery, immunotherapy, human therapy, or other treatment or any procedure to rid animals of disease or increase their economic value or their products. E.g. Surgery or blood transfusion cannot be patented.
  7. Non-biological processes other than microorganisms in the form of plants and animals, including seeds, varieties, and species, and especially plants and animals are excluded from patenting for production or promotion.
  8. Mathematical methods or business methods or algorithms or computer programs cannot be patented.
  9. Any other aesthetic work, including literary, dramatic, musical, or artistic writing or cinematographic works and television productions is subject to the protection of copyright law and is therefore excluded from the scope of patent law.
  10. In the opinion of the Central Government, inventions that are useful or related to the production, control, use or disposal, or promotion of mining, extraction, manufacturing, physical and chemical treatment, manufacturing, or nuclear energy are not patented.

Benefits of getting a patent 

Patent law makes the inventor the sole owner of their invention and increases their confidence to create more ideas. The owner can get many benefits after getting the patent, some of which are as follows:

  1. Unique access to each claim from the time of initial filing

Patent registration begins to provide benefits to inventors from the first stage, i.e. the time it takes to file for a patent. As soon as the provisional patent application is filed, the applicant is assured of security and assurance that no other person or organization can get ideas similar to his invention. If another person applies for the same patent, their request will be denied at the time of filing, which is 12 months in India.

  1. Freedom to change

Patent law gives the owner the right to use his ideas in any way for as long as allowed. This means that the owner has complete freedom to use, sell or modify the original invention and to prevent others from profiting from the same idea without his permission. Once a patent is granted, the inventor can sue the consumer who is found to have infringed his or her patent rights. Note that patent infringement is a criminal offense.

  1. ROI (Return on Investment)

Sometimes, the owner realizes that his invention is not giving him good results and therefore, he wants to hand it over to a qualified or successful person. Once acquired, the patent right allows him to earn a good amount of ROI, i.e., return on his investment by commercializing the invention.

  1. Chances of getting a good name in the market

Patent rights allow the inventor to gain a recognizable market position and improve his portfolio by publicly disclosing the invention. This will help him to develop better relationships with customers and competitors, which will ultimately contribute to his income.

  1. Public exposure

Patent rights allow for public disclosure, which helps the inventor build his portfolio, while at the same time increasing funding, market value, and business partners. Publicly sharing information related to innovation demonstrates a good grasp of the skill and technicality of the inventors. All of these facts benefit the employer by attracting major and top-level investors, shareholders, business partners, and customers.
