Part of the settlement:

Production and importation of the original design GSG-5 ceased as of Oct, 8, 2009 with the signing of the agreement. The remaining inventory now in the USA can be sold by ATI, all distributors and dealers. ATI currently has GSG-5’s in stock.

All sales of the GSG-5 by ATI must conclude by January 31, 2010.

This is a bit of a bummer, but I wouldn’t be surprised to see a very similar gun that does not infringe on someone’s rights out in the near future.
