Indian Patent Search System

A patent is a national monopoly granted by the government for an invention. The patent prohibits others from copying the invention. The patent is given for a period of 20 years. Patent search pertains to the search of the patent database to confirm if there are any patent applications similar or identical to an invention that is yet to be patented. Patent search improves the chances of getting a patent registration and finding information about the inventions that are already patented. The Indian Patent Search System- called InPASS, was introduced in Feb 2015. InPASS facilitates a full-text search of Indian patents and Patent Applications. It also enables conducting an advanced patent search using Wild Cards and Boolean Operators. The Indian patent office database is used to conduct an advanced patent search in India. It is indispensable for a patent attorney to conduct a patent search before doing a patent filing application and proceeding with the patent registration process.

Keyword Search

To start with the search, first, you have to gather the keywords relevant to your invention or patent. You can do the keyword search for searching the title, abstract, claims, and description. You can carry out the patent search using the keywords along with 'Boolean Operators' and/or 'Wild Cards'. The search results will be reflected in two columns. In the left column, the application number/patent number, title, application date, and status will be shown. Based on the choice of a row in the left column, details like Bibliographic Data, Specification, publication number, publication date, publication type, and Status of the patent application/granted patent will display in the right column. Then, you can view the details of the patent specification, priority number, priority country, priority date, the field of invention, and application/patent status in the respective tab. Once you enter the required keywords in the respective boxes, you have to clear the captcha code. However, the display numbers of search records are limited to up to 1000 and 25 records per page.

Applicant Name Search

You can search the patent applications/ patents by entering the applicant's name against the relevant row on the Indian patent search database. The result will be displayed by the title of all published or granted inventions in the name that you entered.

Inventor Name Search

Just like the applicant name search, the Indian patent search database also displays the inventor's name in the relevant row and displays the result. Further, you can also perform various other searches related to the patent. The tab ‘Help’ aids you in learning more about the usage of Boolean operators and Wild cards. Knowledge of USPTO patent search or WIPO patent search will help you conduct the patent search in India very easily.
