Interesting...this all seems pretty funny to me, it's like, "Oh yeah, you aren't dismissing our case...we are just choosing not to amend it at this time, and we reserve the right to amend it again at some future date..."The reference seems to be this...
15 a (2) Other Amendments. In all other cases, a party may amend its pleading only with the opposing party's written consent or the court's leave. The court should freely give leave when justice so requires
What that seems to mean in this context is, "We ask the court to agree to open this case again if we find something eventually ..."
This was clearly a fishing expedition, but if Crytek ever does find a copyright violation... they're just putting CIG on notice. They haven't given up, just conceding the round.
But basically, they can't start all over again. They have to pick up where they left off with this, and it would seem that anything that would have given them a big win/big sum of money has been completely taken out of play.
