I submitted a patent paper, Data transmission method for video conferencing and video conferencing systems, to my parent agent early at Sep, 2014.

It is a patent with H.460 involved, origin from the V5.0 platform system.

But did not get any feedback until the Chinese New Year of 2015.

And after a few days of discussion and revision, finally got it finished. So, yes, the efficiency of patent agent could also be great once they decided to start.

Here is the Patent Application No. 201510096936.3
