Supreme Court Holds That Certain Aspects of Claim Construction Decisions Merit Deference on Appeal

USToday on IPcopy we have a handy review courtesy of Wolf, Greenfield & Sacks, P.C. of the recent Teva Pharamceuticals v Sandoz case in the US.

On January 20, 2015, the U.S. Supreme Court issued its opinion in Teva Pharmaceuticals USA, Inc. v. Sandoz, Inc. The Teva case alters the way the U.S. Court of Appeals for the Federal Circuit (Federal Circuit) will review decisions concerning how patent claims should be construed and whether particular claims are invalid as “indefinite.”

While the ultimate issues of claim construction and indefiniteness will remain legal questions that get a fresh look on appeal, Teva requires that the Federal Circuit defer to the district court’s findings concerning subsidiary facts unless those findings were “clearly erroneous.” Until now, the Federal Circuit has taken a fresh look at even these subsidiary questions, such as whether a person skilled in the art would have understood certain claim terms as having particular meanings.

Teva is likely to impact patent litigation both substantively and procedurally. The substantive changes may take time to develop, whereas certain procedural shifts (e.g., increased reliance on expert witnesses for claim construction) could emerge quickly. (more…)

The United States Supreme Court Announced A New Standard For “Indefinite” Patent Claims, But It May Be Closer To The Same Old Thing

While critically important, claim construction has only infrequently received serious attention from the highest US Court.  Let’s face it – claim construction is not exactly exciting. Maybe that’s why we were all so excited here in the US on Monday, when the Supreme Court issued a decision in Nautilus v. Biosig Instruments in which it set out a purportedly new standard for determining when a claim has met the US Patent Act’s requirement that a claim be clearly defined.  The trouble is that we may have to wait a while before we figure out what that standard actually means.   (more…)
