BOSTON—As the new year began, the war of words between Waltham, MA-based Harlequin and Foster City, CA-based Electronics for Imaging (EFI), heated up.

The San Francisco court ruled for EFI on all 17 issues raised by Harlequin. EFI officials say the San Francisco court's rulings pave the way for EFI to fully press its infringement case against Harlequin.
