Federal Circuit Upholds PTAB’s Ruling on Stem Cell Patent Validity

The United States Court of Appeals for the Federal Circuit has supported a decision by the Patent Trial and Appeal Board (PTAB) concerning a stem cell patent. The PTAB’s initial decision faced a challenge from a biotech research outfit, which the Federal Circuit judges declined to reconsider. This outcome approves the board’s prior ruling that sustained the validity of the stem cell patent in question.
