I agree patent laws are abused/overused (cough cough Qualcomm) but the solution is not to get rid of them altogether, but to reform them to make them more sensible.
In any case, I think right now Ericsson definitely needs to assume that Chinese will use their technology at some point and plan for that contingency.
Patent law is far overreaching in both breadth and length. Anything that undercuts it is a good thing.
