Overview of “Patent”

The term “Patent” is considered to be one of the pillars or categories of Intellectual Property Right (IPR) in India.  Patent is a kind of right granted by the government of India to the inventor on his or her invention. Further, the term “right” includes the authority to make, sell, use, and import of the product or process and restricts others from doing the same.

Patent Law in India is governed and regulated by the Patent Act 1970 and Patent Rules 1972. Any patent once granted to an inventor in India remains valid for a time period of 20 years.

Moreover, the application for Patent Registration is managed by the Patent Office, Controller General of the Patents, Designs and Trade Marks in India.

Indian Patent Search System

InPASS or better known as The Indian Patent Advanced Search System was introduced for the first time in India on 27th of February 2015. However, prior to InPASS, the patent search system in India was conducted by the IPAIRS which stands for Indian Patent Information Retrieval System.

The Indian Patent Advanced Search System (InPASS) is an updated version of IPAIRS. This version allows for a full-text search of all the Indian patents along with all the Patent Applications.

Moreover, InPASS also allows an individual to conduct a patent search using Wild Cards or even by using Boolean Operators. Thus, we can say that InPASS is the Indian patent office database which is used to conduct an advanced patent search in India.

Conducting a patent search in India is deemed to be an indispensable act before filing of the patent application. Thus, it is important for an applicant to know and understand in detail about the process which is to be conducted for patent search system in India.

Meaning of Patent Search

In India, the term “Patent Search” denotes a search of already published patent applications along with the issued patents. Thus, Patent Search is a type of a step which is taken by the applicant before applying for a Patent Registration in India.

However it can be stated that a Patent Search provides “Prior Art” references to the Inventor regarding its invention. The term “Prior Art” means anything which is available for the applicant on a Public Domain, whether the information available is patented or not.

Therefore, it can be concluded that the process of Patent Search is beneficial for the inventor as it helps to check the novelty of his or her invention before applying the same for Patent Registration.

  • The main aim for patent search engine is to expose most of the similar inventions. Thus, the benefit of a patent search lies in the uniqueness of the invention.
  • The patent search engine result also helps an applicant in knowing and forming a basis of the cost expenditure that he or she is about to invest in his invention.
  • These patent search results also benefits any patent attorney who is drafting patent application thus, keeping in mind any prior arts.

Why A Patent Search Necessary?

  • Every single year, there are hundreds and thousands of patent applications which are being applied by patent authorities in order to get it patented.
  • However, it can be seen clearly that not all applications are approved by these authorities because of the reason that there are other similar inventions or applications or steps involved in the invention, and hence not innovative.


In India, various pharmaceutical companies file application for patents every year whenever their research and development team invents either any new product or even the ‘steps’ involved  to formulate or derive any particular active ingredient in the composition of a specific drug. However, most of the times these drugs are not deemed to be innovative and thus the innovation is not registered under Patent Act.

Thus, it can be stated that an applicant should not waste time on the patent process; rather it is best to find out the same through Patent Search in case of any similar inventions or applications already patented.
