Quick tips and tricks from Asia

Dear users,

Did you know that the Indian Patent Office administers a database containing expired or lapsed patents which are entering the public domain in India?

This IPO database is called Dynamic Patent Utilities and patents which are entering the public domain can be viewed here in two groups:
• expired patents
• patents which lapsed due to non-payment of the renewal fees

Quick check whether the patent is among the lapsed or expired ones can be done by searching with the patent number of title of the invention.

In case of any questions, please post them here at this discussion forum or contact us directly at

With kinds regards,
