IP infringement seems to be the flavor of this season.Its actually sometimes very confusing if someone has really infringed the IP or other party delayed to apply for it in th efirst place. It must be very demotivating for the party who lost.
Sidense seems pretty confident that this ruling (and the three reasons the court gave for ruling that Sidense did not infringe) is pretty much the end of the road for this litigation. But time will tell. The wheels of justice turn slowly, especially in these IP infringement cases.
