Stone Basket Innovations, LLC v. Cook Medical LLC, No. 17-2330 (Fed. Cir. 2018)Annotate this Case
Stone sued Cook in the Eastern District of Texas, alleging infringement of the 327 patent, which relates to a basket-type medical device used to remove stones from biological systems. Venue was transferred to the Southern District of Indiana. Cook deposed the patent’s inventor, who stated, regarding the addition of the “sheath movement element” in claim 1 to overcome an examiner’s rejection, “I realize there is nothing novel about it.” Cook then petitioned the Patent and Trademark Office for inter partes review of all claims. Following the institution of IPR, one of Stone’s managing members offered to license the 327 patent to Cook for $150,000.00 but negotiations broke down. The Patent Board canceled all of the patent’s claims. Following a dismissal with prejudice, the court denied Cook’s motion for attorney fees, 35 U.S.C. 285. The Federal Circuit affirmed, agreeing the case was not “exceptional” and that Stone lacked any type of “clear notice” of the 327 patent’s invalidity by service of Cook’s invalidity contentions. While one might view Stone’s litigating position as weak given the inventor’s deposition testimony regarding the novelty and origin of claim 1’s sheath handle element, exceptionality is not assessed by a strong or even correct litigating position.
