Mark, you're right, Titleist benefits from the Pro V1 indirectly, as well as directly. But that just means that they should be willing to pay more for a license. If you're Callaway, you can make Titleist pay dearly for the license, weakening Titleist net profits, and bank some big profits of your own for some time to come just by taking the licensing fees. If the Pro V1 is enjoined, there's no guarantee that the Callaway ball is going to come out the winner in the new "post Pro V1" world -- it might be another Titleist ball, or Nike, or someone else...and Titleist devotees might blame Callaway for the fact that they can't buy their ball of choice. Why not take the big bucks from Titleist, and use some of that money to market your own ball...whether you succeed in toppling Titleist as the golf ball king or not, you win either way.
Callaway has some interesting choices ahead. So does Titleist...Titleist might decide that it doesn't want to keep producing the Pro V1 as currently designed, and come out with a new version that doesn't infringe, counting on its big name to bring golfers over to the new ball. Lots of folks think that Titleist has some magical ability to build a superior ball, it's possible the company could pull it off.
