Count, I believe that you're reading far too much into Janet's comments and give her comments too much credit for divulging information in what she has stated to you. I have had conversations with her as well, and her statements are perfectly vague. She will not divulge what type of enforcements exist in the contract and she certainly won't tell you what Interdigital would do if payments aren't made. She likely doesn't even know what action the company would take in such a situation.
Samsung has made an agreement and will pay. I believe it is a choice between lump sum and per unit, or some variation therein. They will be looking at what will be their cheapest option given their own projections, exchange rates, time value, taxes where applicable, etc.
Don't read too much into Janet's comments, thay're not as deep and as meaningful as you wish to credit them.
IMO
