Atari and other game publishers have come to a settlement with American Video Graphics, a company which claims a patent on (essentially) an in-game camera POV. Atari agreed to pay the company $300,000 for 'irrevocable' rights to the company's patents
. From the article: "In a recent IGDA column on the subject, lawyer Jim Charne commented on the danger of this exceptionally wide-ranging patent, noting that: 'Several of these defendants have joined together to mount a common (and very costly) defense', and further commenting: 'The '690 patent litigation is an attack on the industry as a whole. It is indeed something for developers to worry about.'"
The other companies mentioned, apparently, came to similar settlements. It's frustrating to me that these companies chose to buy off a pointless suit like this, rather than see the patent nullified.
