Indian Patent Search: Alternatives

[tweetmeme source=”Intellogist” only_single=false]

India is a fast growing economy with a fast growing appetite for intellectual property. We explored this issue last year with our profile of the iPairs system (a must read). On the other hand, several commercial patent search systems such as PatBase, the Questel/Orbit systems, TotalPatent, and CIPIS offer different levels of Indian patent coverage to go along with their respective features and interfaces.

What if you’ve taken a look at these options and they’ve left you wanting? Today we’ll look at India BigPatents and First Indian Patent Searchable Database Ekaswa, two interesting (and free) alternatives for your Indian patent searching needs.

Join us as we look to see if these Indian patent searching systems are worth checking out!

India BigPatents is a simple search system that puts a lot of information at the user’s fingertips without many frills. Data included in the full listing of the patent applications includes title, publication number, filing date, publication date, abstract, applicant, inventor, and international classification information. A link to the application at the Indian Patent Information Retrieval System is also given once the user views an individual result.

Aside from being functional (and fast) one of the best reasons to use India BigPatents is the representative drawing included on most individual results pages.

Representative drawings and a link to the official Indian patent office site are present when available.

The First Indian Patent Searchable Database Ekaswa comprises three separate search interfaces for its three databases:

  • Ekaswa A: “Patent applications filed in India as published in the issues of the Gazette of India (Part III, Section 2) from January 1995 to December 2004.”
  • Ekaswa B: “Patent applications notified for opposition in the Gazette of India (Part III, Section 2) published from January 1995 to December 2004.”
  • Ekaswa C: “Patent applications published in official Journal of Patent office published from January 2005 onwards.”

Searchable fields vary per database, but generally Number, Applicant, Title, and Inventor fields are present. Results are displayed in a simple format, requiring a login to see the details. Despite there being a guest/free login available, I was not able to access details of any of the results during limited testing.


The results interface is very simple, but does include English Titles and document numbers (not shown here).

The first considerations when trying to get a searcher to use any new patent search system are user interface and functionality. If the system is easy to understand and works (relatively quickly), it’s likely that you can persuade even a veteran searcher to give the system a try to see if it fits his or her needs. India BigPatents passes these tests, and that makes it a system worth checking out if you need free access to Indian patent data. First Indian Patent Searchable Database Ekaswa, on the other hand, leaves much to desired (at present) with the constant timeouts and sluggish performance.

It’s always fun to check out niche patent search systems such as these in developing or under-served patent havens around the world. Doing so seems like stepping back in time compared to the monolithic commercial systems of today. Once in a while you might find a jewel, like we did with AusPat last week, but other times you might find another solid database to insert into your trusty bookmarks!

Have you tried either of these systems? We’d love to hear your feedback in the comments below!
