Ed, I haven't analyzed the entire TI case, but based on the data in your post:
* It doesn't matter that the company bought stock back since dilution is still a high cost to investors (either directly via dilution or via the use of company funds to buy treasury stock).
* Treasury stock is typically resold so it will re-inflate the outstanding shares eventually.
* 14% ISO dilution is excessive, IMO;
* The (TI promoted) chart you pointed to seems to show TI at the bottom of the list, however, this is a distortion. Most public companies should be in the under 1-2% per year range, and that is a REASONABLE level.
* TI, at 2% per year is pushing the envelope of reasonable IMO.
* All the other companies shown by TI to be above 2% per year are screaming abusive to public shareholders, IMO.
Roughly speaking, IDCC would be around 30% in the past 5 years or 5-7% per year for the past 5 years, well above the upper end of REASONABLE, and well into the screaming abusive range, IMO. Actually, the RATE of ISO grant at IDCC is even higher using a past 3 years timeframe.
Just my perspective,
