Janssen Biotech Inc. v. Celltrion Healthcare Co. Ltd. (18-2321).

The Federal Circuit upheld Celltrion’s non-infringement victory at the District Court in a summary affirmance, meaning that no opinion was written. Janssen had sought infringement under the doctrine of equivalents, but Judge Wolf found that the claims, if extended to cover the equivalents sought, would have been obvious, and that Celltrion therefore did not infringe.  This should bring the lawsuit to a close.
