Patent Search in India

A patent is granted for a new or novel invention , having an inventive step and capable of industrial application. It is therefore advisable to conduct a search before investing time and resources in developing any new technology in order to access whether the technology being worked on is new or novel, to avoid reinventing the wheel and also to safeguard from infringing an existing patent right and accordingly conduct a patent search.

The various types of patent application searche which may be conducted depending on the objective are:

Freedom To Operate Search (FTO) in India :

How to Conduct Freedom To Operate Searches For Patents in India?

Freedom to Operate (FTO) search is also known as Right to Use search. The companies prior to making huge investments like launching a new product or initiating a new line of research leading to development of new product perform FTO search in order to ensure that the commercial production, marketing and use of their new product, process or service does not infringe the intellectual property rights of others.

FTO includes a comprehensive search and analysis of patent literature i.e. un-expired patents and published patent applications. However, while conducting such searches, it is imperative to bear in mind that patent protection is territorial and have limited scope and duration.

Freedom to operate searches can be used:
  • For mapping out a technical field
  • To know the possible infringement
  • To know the countries where possible rights apply
  • As inspiration prior to the commencement of a new development project
  • To know who is operating within a given field
  • To evaluate the potential for new activities in an area

How to Conduct Patent Prior Art Search in India?

Prior Art search is conducted so as to determine the status of a technology in reference to development in the field. The search is conducted on various databases in order to obtain relevant patents and/or published patent applications which are parallel to the particular technology.

Once a Prior Art search is conducted, it will clearly mention the technical problems associated with the existing technology and the solution for that, bringing out the differences between the claimed invention and prior art.

The analysis and insights from the report helps in guiding or deciding R&D and IP strategy of the company or industry and to better evaluate the economic value of the patent portfolio.

A patent landscape analysis helps to identify:
  • Technology strength
  • Technology white space
  • Technology leaders and their IP strategies
  • Technological positioning of companies and their chronological changes
  • Strengths and weaknesses of patent portfolios
  • Innovative focus of companies
  • Filing trend of companies in a technology domain
  • Foreign filing trends etc.
