Overview of Indian Patent Search

The patent search is the first step any person takes before filing a patent application. A patent search is a process of browsing through the patent database to determine whether there are any similar patents to the invention/innovation of the applicant. This process is done to make sure that the applicant's patent is unique and has a higher chance of getting a registration. Registration of a patent ensures that the patent holder has the ultimate right to use that innovation but if the application for the innovation or invention is similar to a pre-existing patent then the patent office shall reject the application.

What is InPASS?

In India, the patent search can be conducted through the Indian Patent Search System (InPASS). It was introduced in the year 2015 as a replacement for its predecessor called IPAIRS (Indian Patent Information Retrieval System). InPASS allows the user to conduct searches both via. Wild cards and Boolean operators. Currently, the InPASS is the most advanced database to conduct a patent search in India

Importance of Patent Search

  • Saves Time and Money: A basic patent search can let the inventors know whether there are any similar products as compared to their innovation. They can do a patent search and proceed accordingly thereby saving their time and effort.
  • Protects from Infringement: when an organisation decides to pursue a project, it must ensure that its innovation is not infringing any pre-existing product whose patent has already been registered.
  • Product Development: The patent search will enable a company to study the product design of its competitors. This research will result in them finding flaws/ gaps/ loopholes in the technology on which the company can capitalise.
  • Cost and Validity: A Good patent search shall help the innovator determine the value and validity of a patent before they decide to sell or buy any patent.
  • Invalid Patents: After completing a patent search we can get information on patents that have expired or have become invalid, then these innovations can be used without the need to pay any royalty to the founder.
  • Understanding Trends: Patent searches often reveal the latest trends in a particular technology this will help the innovator to develop products as per the demand of technology.
  • Patent Portfolio: A thorough patent search will assist in learning about a company's patent portfolio i.e. which all patent is owned by a particular company.
