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.
