The litigation campaign of CellSpin Soft, Inc., launched in 2017 against 14 different defendants, has twice been stalled by trips to the Federal Circuit. The first time, the appellate court reversed an Alice invalidation, ginning activity back up—until last June when Northern District of California District Judge Yvonne Gonzalez Rogers granted summary judgment of noninfringement. An appeal of that decision is underway. Now, CellSpin Soft has sued one of those 14 defendants again, accusing Panasonic (4:17-cv-05941) of infringing six patents from the same family but not previously litigated. However, the new complaint, like CellSpin’s last one, has not been filed in the Northern District of California.
