Appeal No. 2000-1449 Application No. 08/838,133 Sport Cap” is attributable to the “hook-shaped flange of the present invention.” However, the appealed claims do not require a “hook-shaped” flange on any of the tamper-evident rings. Moreover, for all the record shows, the $11 million in revenue and increased rate of sales for the “28mm Sport Cap” could just as easily be attributable to increased popularity of the sports beverages contained in the bottles to which the closures were applied. As to Mr. Long’s statement in paragraph 5 that the advantages of the appellant’s cap “satisfy a long felt need” in the art, in order to establish long felt but unresolved need it must be demonstrated that a problem has been recognized in the art and remained unsolved over a long period of time,6 and that the claimed invention satisfied the long felt need.7 Mr. Long’s statements do not address these issues. Instead, they merely allege, without any factual support, that the claimed invention satisfied a long felt need. 6Vandenberg v. Dairy Equip. Co., 740 F.2d 1560, 1567, 224 USPQ 195, 199 (Fed.
