Here is an update on recent en banc activity at the Federal Circuit in patent cases. Since our last update, the court received a petition raising a question related to patent eligibility. The court also issued an invitation for a response to a petition raising a question regarding Article III jurisdiction to adjudicate patent infringement when the relevant patent has already expired. The court has also recently denied two petitions. The first denied petition raised a question concerning whether an abandoned patent application that becomes publicly available only after a challenged patent’s critical date is a printed publication that can form the basis for an inter partes review proceeding. The second denied petition raised questions concerning expert testimony to prove infringement of a means plus function element, claim construction, and the reverse doctrine of equivalents. Here are the details.
Recent En Banc Activity
Here is an update on recent en banc activity at the Federal Circuit. Since our last update, three new petitions have been filed, and two previously filed petitions have been denied. The first new petition raises a question related to Article III jurisdiction to adjudicate patent infringement when the patent has already expired; the second raises a question regarding whether a court can rule on a motion for summary judgment of invalidity of a patent after ruling that the plaintiffs lacked standing; and the third raises a question concerning collateral estoppel related to a decision of the Patent Trial and Appeal Board. The two denied petitions came in a pro se case and in an appeal related to obviousness. Here are the details.
