That pop came with a well worded PR which helped the price action. I wouldn't expect another pop based on the same news.
Now, the price is rising slowly as we approach the earnings announcement, a perfect setup to give us a haircut again based on selective negative earnings reporting.
I would suggest that those with major holdings try to protect their paper profits by hedging with some cheap PUTS until after the earnings release no matter how optimistic you are about IDCC's future. If there is no pop or no haircut you can immediately re-sell your PUTS and recoup your insurance premiums. (I wish I had thought of that in the past).
