Now, there are some databases are available to search the patent for published and issued patents.

This is a very nice synopsis of patent searching in India.
But I have had little success with any of these websites to find applications by searching with application number eg 4063/DELNP/2005

Is there a preferred format?

Also is there any way to see full text , especially claims for patent applications

Finally is the Indian Patent Office site working or require special security clearance/ firewall settings?

Any information you can provide will be extremely useful !!!!!

Very informative.

Is there any database, which provides keyword search for patent description?

I am looking for details of a published patent. I am able to get the abstract but am not able to get the full text. The patent for which I need the full text was submitted in the Mumbai office. Any information regarding this would be appreciated.

Hi Senthil, this really is useful info. In case your readers are interested, I wanted to mention that my company has put together an interactive map of global patent coverage, at

It only includes major search sources that we have been able to evaluate, so it is not comprehensive, however it can be useful to give an overview of what major subscription tools offer coverage of a particular country.

I have couple of questions:

1. Does Indian Patent Office (Ipairs) carry a date/time stamp, when they update the legal status or any other information in their portal Online? If not what would be the best way to know, what/when was the status last updated?
e.g. I may want to know XYZ current patent legal status, and if there is an update later - what date was id updated on Ipairs.

2. Also, could you please let me know the list of Indian patent database service providers (co. names) in India?
