GAB, I'm also aware of HG's SEC stint and - in the past - have used that marker to evaluate his actions.
I think you would agree that as CEO, IDCC investors would expect him to have intimate knowledge of the state of play of negotiations with NOK.
Even if his July 7 sale was serendipitous, the July 8 collaboration with Ericsson on the amendment (which could have been filed at any time after March 17 - and could have been in the settlement agreement) looks like too much coincidence (with the July 22 unsealing request) for my taste. JMO, JK
