Bethesda parent publisher moves to extend legal coverage of IP as fate of Prey 2 remains in question.
Zenimax Media has filed with the United States Patent & Trademark Office to extend its trademark for the Prey intellectual property.

The company this month filed three separate applications covering http://1.usa.gov/ZmTy2e, http://1.usa.gov/16MUUts, and http://1.usa.gov/XsmIQZ, among other things.
Asked what these filings may mean for the future of the Prey brand, a company representative declined to comment.
Says it all, really. A few more details in the link.
