How Is A Patent Search Executed in India

A patent is a legal document that gives the right or authority over a particular field of research, invention, or any other process to a person applying for it.

Database Search

A patent attorney will do a thorough search of the patent database.

Step 1

Chances of Approval

The lawyers will assess inventiveness through comparisons with similar inventions.

Step 2


The attorney will then inform you of whether or not you should make the application.

Step 3

Patentability Search - An Overview:

A patent grants the owner the right to restrict others from creating, using, importing, or selling his or her invention without permission. Before such a right is granted, a thorough examination is performed to see whether the procedure or product is original, novel (and has not previously been predicted in any published document), and industrially applicable (possesses utility). It involves searching the database of India's intellectual property authority to see if there is an object or invention that is the same as or comparable to the applicant's creation.

Benefits of a Patent Search

  • It shows the level of competition
  • It confirms whether or not your invention's concept has already been patented
  • It assists with determining which aspects of your innovation are most likely to be patentable
  • It grants you the sole right to prevent others from reproducing, manufacturing, selling, or importing your innovation without your permission.

Documents Required for the Filing of a Patent in India

  • Complete specification (in English)
  • Drawing(s)
  • Name, address, and nationality of inventors
  • Name, address, and nationality of applicants
  • Power of attorney (to be filed in case the application is filed by a patent agent)
  • Assignment deed or application form endorsed by the inventor (if the inventors are not the applicants)
  • Details of correspond­ing applications filed in other countries (Infor­mation and undertaking under Section 8)
  • Verified English translation of the priority application (required for convention applications)
  • Verified English translation of the PCT application (required only for national phase applications) agent can verify the English translation of PCT application on behalf of the applicant
  • Certified copy of the priority application, if requested by the controller (required usually for convention applications, but may also be requested for national phase application in case the priority document was not submitted with the international bureau)
  • Sequence listing in computer-readable text format (if any) (no print form is required to be submitted)
  • Permission from the National Biodiversity Authority (in case any biological material used in the invention is from India).

Why Is a Patent Search Essential for Infringement?

Every year, patent authorities get thousands of patent applications. Not all applications are approved by the authorities. The reason for this is that there are other similar inventions/applications or methods involved in the invention that are not innovative.

For example, pharmaceutical companies in India file for patents every year when their research and development teams invent a product or mostly, the ‘steps’ to formulate or derive a particular active ingredient (drug). Often, these drugs are not innovative and the innovation is not registered. Thus, instead of wasting time on the patent process, it is best to find out through patent search if there are any similar inventions/applications already patented.
