Under such circumstance, what we can do is filing no response to the appeal or filing a response admitting the validity of the use evidence submitted by the adverse party. We told the adverse party we can do so if they agree to sign co-existence agreement. But in their view, filing no response or filing response admitting the validity of their use evidence is not so helpful to them. They told us they need time to consider and they will inform us if there is any news, but up to now we haven't received their further decision.
