ZTE Corporation filed a patent application numbered 521/DELNP/2012 that is titled METHOD AND SYSTEM FOR BEARING TIME SYNCHRONIZATION PROTOCOL IN OPTICAL TRANSPORT NETWORK. The patent has been filed in the field of Communication. This Patent Application has been granted as Patent Number 351301. This invention covers a method and a system for correcting a time when an Optical Transport Network (OTN) bears a time synchronization protocol, which is used for solving the technical problem that the time synchronization protocol cannot be transported normally because of the unfixed transport delay time of the OTN network. In the present invention, when time synchronization protocol data are added in and dropped off the OTN network, a delay time during which the data passes through the OTN network is calculated based on an accurate synchronization time inside the OTN network, and the delay time is written in a correction filed of the time synchronization protocol data packet, thereby correcting the influence on the time synchronization protocol caused by the unfixed delay time in the OTN network.
During the patent examination, the patent examiner raised objections under Section 3(k) of the Indian Patents Act, 1970. It was pointed out that the claims were statutorily non-patentable.
As a response, the Applicant demonstrated that the claims of the invention have technical contribution over state of the art and the present invention solves the technical problem of the prior art by technical means and thus the claims of the invention are not hit by section 3(k) of the Act.
