Nothing FAIR In FRAND (Ericsson- Micromax Patent Litigation)
Ericsson filed patent infringement litigation against Micromax Informatics Ltd. and Mercury Electronics Ltd. for infringing its patents. Essentially these patents relate to use of speech codec (combination of speech coder and speech decoder) for coding the voice signal (in a compressed form) from the caller end and transmitting it via a radio link as coded/ compressed speech frames to the receiver end where it is decoded. Typically in a discontinuous transmission no coded speech frames are send while speaker is inactive. Here transmitter at regular interval sends speech parameter suitable for generation of comfort noise in the decoder. Ericsson states in its patents that speech coders and decoders are conventionally provided in radio transmitters and radio receivers, respectively and cooperate to permit speech (voice) communications between a given transmitter and receiver over a radio link. A mobile phone is a conventional radio communication device comprising a Radio transmi...
