I am a IP guy, I understand and deal oatent applications better than anyone. To my knowledge, 65% of the qcom patents can be invalidated if questioned. These patents are good for patent portfolios, to build your resume, nothing else. In fact many people who got these patents are not even MS level engineers.
Overall qcom cash earning royalty business is under water, not to tell 25-40% lay off is inevitable in coming months after FTC.
