Is the IPR tide about to turn at the Patent Trial and Appeal Board?

Recently the United States Supreme Court added an important IPR case to its docket. Normally the Supreme Court does not take a Federal Circuit appeal to compliment the Court on how well they have resolved a particular matter, so it seems safe to bet that the Federal Circuit will be reversed on one or both of the issues take. At the very least the Supreme Court can be expected to make broad statements of law and principle and remand the case for further consideration. In either event the outcome would be welcomed by patent owners. In the meantime as we wait for a decision it will also be interesting to watch and see if the PTAB begins to moderate and whether the Federal Circuit shifts their jurisprudence, as they have been known to do from time to time while awaiting a decision from the Supreme Court.

The Doctrine of Claim Differentiation: Who Got It Right in Retractable Technologies?

Whether the term “body” encompassed “multi-piece” structures became the crux of the claim construction issues in Retractable Technologies. The District Court for Eastern Texas, apparently applying the doctrine of claim differentiation, construed independent Claims 1 and 43 to cover a “body” which might be a “multi-piece” structure. Accordingly, the District Court denied post-trial motions by the alleged infringer (Becton Dickinson or “BD”) to overturn the jury verdict that BD infringed these Claims of the ‘224 patent. Judge Lourie (writing for the panel majority) reversed the District Court, ruling that the term “body” was limited to a “one-piece” structure in light of the ‘224 patent specification.
