Checkpoint Systems, Inc. v. All-Tag Security S.A., et al.

Checkpoint Systems sued All-Tag for infringement of their patented, disposable, deactivatable anti-theft security devices. All-Tag motion for summary judgment was granted because Checkpoint failed to name all inventors. On Appeal, the CAFC found that there was a material issue of fact when Checkpoints statements regarding inventorship during prosecution conflicted with later statements during litigation declarations.
