Lockformer Co., et al. v. PPG Industries, Inc.

Lockformer and PPG Industries are competitors in insulated, multi-pane glass. PPG alleged that Lockformer infringed their patent for a new kind of glass spacer and spacer frame. After close of PPG evidence, Lockformer prevailed on a motion for summary judgment because PPG failed to present any evidence that Lockformer's product did not contain an adhesive adhering to a flat metal strip. The CAFC affirmed.
Note that this opinion may not be cited as precedent.
