Carlsbad, Calif.-based Callaway Golf Co. has prevailed in one patent infringement dispute and settled another.

The manufacturer of golf clubs, balls and accessories announced Dec. 14 that a jury for a federal district court in Delaware had found for Callaway on four of its five claims against Acushnet Co., the company behind the Titleist brand. Callaway had claimed the Titleist Pro V1 golf ball infringed on five of its patents; the jury found Acushnet had infringed four of those patents.

Acushnet has countered that the Titleist Pro V1 is based on more than 70 of its own patents. In a statement, Acushnet said the jury ruling leaves some ambiguity and that it awaits a decision on motion for judgment.

Acushnet Executive Vice President Joseph Nauman said in a statement, “The jury's mixed decision has created ambiguity that will have to be resolved post-trial.

Also on Dec. 14, Callaway and TaylorMade Golf Co. announced they had reached a settlement and patent license agreement, resolving all pending litigation between the companies and specifying both companies' rights to make products under patents owned by the other company.

According to the companies, “Technologies at issue include high moment of inertia drivers, undercut irons and golf balls.” Settlement details were not released.

“We are very pleased that the parties were able to reach agreement while respecting the core technologies that set them apart from each other and from other golf companies,” said George Fellows, president and CEO of Callaway.

In the November issue of InsideCounsel, Callaway GC Michael Rider explained, “If you think about it, we're competing against much bigger companies for a share of the market. One of the areas in which we compete is obtaining and enforcing our IP rights.”
