It seems IDCC has two deadlines for filing legal rebuttals. August 17th and August 25th. Since August 17th falls on a Sunday does that mean the filing is due on the previous business day or the next business day? Hopefully the latter since we haven't seen anything yet.
Another sign that IDCC's IPR is not as strong as many believe is that IDCC is always filing court papers defensively. Even with the Motorola suit way back in 1995 IDCC did not file until AFTER Motorola did. Just one more clue of many, don't ignore them.
