Golf ball patent wars continue

Carlsbad's Callaway Golf and Titleist parent Acushnet lobbed patent infringement lawsuits at each other yesterday [March 3] – the latest round in an ongoing spat over top-quality golf balls.

Callaway alleges that Acushnet's latest version of the popular Titleist Pro V1 and Pro V1x balls infringe on patents Callaway acquired as part of its purchase of competitor Top Flite in 2003.

Acushnet, a division of Fortune Brands based in Fairhaven, Mass., filed a separate lawsuit against Callaway. It alleges Callaway's Tour i and Tour ix premium golf balls infringe on nine Acushnet patents. The patents involve things such as dimple pattern, core construction and the manufacturing process.

One wonders the position of golf ball people on patent reform [?]
