December 9, 2014 – In an Inter Partes Review, the PTAB found that TriVascular had not proven, by a preponderance of the evidence, that claims directed to an inflatable intraluminal stent were unpatentable. The PTAB agreed with the patent owner in that the cited prior art combination did not include the claim limitation of “inflatable protrusions” to prevent longitudinal movement of the stent. The patent-at-issue was U.S. Patent No. 6,007,575, entitled “Inflatable Intraluminal Stent and Method for Affixing Same Within the Human Body.” The case is captioned Trivascular, Inc. v. Samuels, Case IPR2013-00493.
