Introduction to Patents​

Patents are a form of intellectual property rights granted to inventors for their inventions. They protect novel and non-obvious inventions from unauthorized use by others. India, patents are governed by the Patents Act, 1970, which came into force on April 20, 1972.

  • Section 2(a) defines "patent" as "a grnt of rights made by the Controller under this Act"
  • Section 3 lists exceptions where inventions cannot be patented
  • Section 4 deals with the filing of patent applications
  • Section 10 specifies the conditions for granting a patent

Eligibility Criteria for Patent Protection​

To be eligible for patent protection, an invention must meet certain criteria:

  1. Novelty: The invention must not have been publicly known or used before the date of filing the application.
  2. Non-obviousness: The invention must not be obvious to a person skilled in the art.
  3. Utility: The invention must have practical utility.
  4. Inventive step: The invention must involve an inventive step.
  • Section 2(d) defines "invention" as "any manner new and not obvious to a person skilled in the art"
  • Section 3(1)(j) lists inventions that are not patentable due to lack of inventive step

Types of Patents​

India recognizes two types of patents:

  1. Conventional Patents: These cover processes, machines, manufactures, and compositions of matter.
  2. Micro-Organism Patents: These cover microorganisms and products produced through microbiological processes.
  • Section 5 deals with conventional patents
  • Section 5A deals with micro-organism patents

Patent Application Process​

The process of obtaining a patent involves several steps:

  1. Filing a provisional application
  2. Filing a complete specification within 12 months of the provisional application
  3. Publication of the application
  4. Examination by the Patent Office
  5. Granting of the patent
  • Section 7 deals with the filing of provisional specifications
  • Section 9 deals with the publication of applications
  • Section 11 deals with the examination of applications

Examination and Granting of Patents​

After filing the complete specification, the application undergoes examination by the Patent Office. If the examiner finds that the invention meets all the requirements of the Act, the patent is granted.

  • Section 13 deals with the examination of applications
  • Section 45 deals with the grant of patents

Patent Rights and Limitations​

Once a patent is granted, the inventor enjoys exclusive rights over the invention. However, there are limitations to these rights:

  1. Right to prevent others from making, using, offering for sale, selling, importing, or distributing the invention without permission
  2. Right to assign the patent to another party
  3. Right to license the patent to others

However, these rights are subject to certain limitations:

  1. Working requirement: The patentee must work the invention commercially within three years of the grant of the patent
  2. Compulsory licensing: The government may grant licenses to third parties if the patentee fails to work the invention
  3. Revocation: A patent can be revoked if it infringes public order or morality
  • Section 47 deals with the right to prevent infringement
  • Section 70 deals with compulsory licensing
  • Section 72 deals with revocation

Infringement and Remedies​

Infringement occurs when someone uses or makes the patented invention without permission. There are various remedies available for patent infringement:

  1. Injunctions: Courts can issue injunctions to stop infringement
  2. Damages: The patent owner can claim damages for past infringement
  3. Account of profits: The infringer may be required to account for their profits
  • Section 104 deals with civil actions for infringement
  • Section 105 deals with criminal actions for infringement

Case Studies and Illustrations​

While space constraints prevent us from providing detailed case studies here, we recommend consulting the following cases for further understanding:

  1. Monsanto Technology LLC v. CMC Petrochemicals Ltd. (2017): This case dealt with the infringement of a patent related to genetically modified cotton seeds. The Supreme Court upheld the validity of the patent and awarded substantial damages to the patent holder.

  2. Novartis AG v. Union of India (2007): This landmark case challenged the constitutionality of Section 3(d) of the Patents Act, which requires enhanced efficacy for chemical compounds. The Supreme Court upheld the provision, affirming the government's power to regulate pharmaceutical patents.

These cases demonstrate the practical application of patent law in India and highlight the importance of considering both legal and commercial aspects when dealing with intellectual property rights.
