ST. JUDE MEDCAL, LLC v. SNYDERS HEART VALVE LLC

ST. JUDE MEDCAL, LLC v. SNYDERS HEART VALVE LLC, Appeal Nos. 2019-2108, 2019-2109, 2019-2140 (Fed. Cir. October 15, 2020). Before Taranto, Newman, and O’Malley. Appealed from the PTAB.  (Claim Construction)

Background:

Snyders owns a patent for an artificial heart valve that can be implanted with a catheter, without invasive surgery, and without removing a damaged native heart valve.  St. Jude filed two inter partes review (IPR) petitions, relying on distinct prior art references in each petition, seeking to invalidate the claims of the patent.

In the first IPR, the PTAB ruled that St. Jude failed to establish that the challenged claims were unpatentable.  In the second IPR, the PTAB ruled that claims 1, 2, 6, and 8 of the patent were anticipated.  Both parties appealed to the Federal Circuit.

Issues/Holdings:

(1) Did the PTAB properly construe the term “band” in finding no anticipation?

(2)  Did the PTAB properly construe the phrase “a flexibly resilient frame sized and shaped for insertion” in finding anticipation?  (continue reading)
