Fish and Nicmar, it it entirely possible that deep pocket investors sent their hired techies to peruse the patent improvements that were granted to IDCC following the ITC's non infringement ruling.
The fact that the patents in suit at the ITC were deemed valid but not infringed says a lot. And then for IDCC to go back and have the claims further clarified to close the noose so that infringement is "EVIDENDT" rather than debateable says alot. As IDCC has said the ALJ helped IDCC to have the patents solidified. And Nokia like all serious investors are aware that those patents are really tight now. Even though the old patents were more than enough in their claims of code, chips, signal and bandwith.
