North, 180 is a notification of service. I don't see any details involving the argument for invalidity. I am a bit surprised that Hikma doesn't oppose the meaning of the wording in the asserted patents. Either the Hikma legal strategy doesn't rely on contesting the meaning, or they don't think they can invalidate the patents. No reason for the extra expense. I get a sense of panic from the Hikma legal team. Sleven,
