How to find Patent Application Status in India?
Patent Application Status in India: Many patent clients ask this question as to what is the status of their patent applications filed in India. In recent past things have changed and Indian patent office is expediting the patent grant process. The following sections of this IP article provides details of patents granted in electrical domain in India.
In the technology field of electrical domain, the Indian patent office (IPO) recently granted patent for an invention titled “SUB-BAND VOICE CODEC WITH MULTI-STAGE CODEBOOKS AND REDUNDANT CODING” to Microsoft.
The granted Indian patent relates to techniques and tools related to coding and decoding of audio information. For example, redundant coded information for decoding a current frame includes signal history information associated with only a portion of a previous frame. As another example, redundant coded information for decoding a coded unit includes parameters for a codebook stage to be used in decoding the current coded unit only if the previous coded unit is not available. As yet another example, coded audio units each include a field indicating whether the coded unit includes main encoded information representing a segment of an audio signal, and whether the coded unit includes redundant coded information for use in decoding main encoded information.
