LG Electronics announced that they will be tough on this patent lawsuit to protect their business and Pantech is also planning to response actively after they identify the exact contents of the lawsuit.

However, it seems hard to LG and Pantech do a counter-suit against Acacia.  NPEs usually own the patents but not manufacture or use the patented invention which makes counterparts to raise issues related to infringement problems.
