Petition of the day

The petition of the day is:


Issues: (1) Whether, and under what circumstances, assignors and their privies are free to contest a patent’s validity; and (2) whether the U.S. Court of Appeals for the Federal Circuit erred in holding that proof of but-for causation, without more, satisfies the requirement that damages be apportioned between patented and un-patented features.
