Callaway Golf has won a patent infringement case against Acushnet, the maker of the popular Titleist Pro V1 ball.

Callaway filed suit in June in U.S. District Court in Delaware alleging Acushnet’s Titleist Pro V1 line of golf balls infringed on patents owned by Callaway. Jurors found in favor of Callaway on four of the five patents, Callaway spokeswoman Michele Szynal said Dec. 14.
