On August 5, 2013, TriVascular, Inc. filed a petition with the Patent Trial and Appeal Board requesting inter partes review of U.S. Patent No. 6,007,575 owned by named inventor Dr. Shaun L.W. Samuels.
The ’575 Patent is entitled “Inflatable Intraluminal Stent and Method for Affixing Same Within the Human Body.” The ’575 Patent states that it relates to “[a]n inflatable intraluminal stent for attachment to the interior surface of a tubular structure within the human body” featuring “a cuff having an inflatable chamber and a friction-enhancing outer surface” that “engages the interior surface of the tubular structure without penetration when the inflatable cuff is in an inflated condition.” Figure 1 from the ’575 Patent is shown below:
The petition seeks review of all 24 of the ’575 Patent’s claims. The petition discloses that the ’575 Patent has been asserted by Dr. Samuels against TriVascular in a lawsuit filed in the U.S. District Court for the Northern District of California. The complaint, filed on May 17, 2013, alleges that TriVascular’s “Ovation Prime™ Abdominal Stent Graft System” infringes the ’575 Patent.
