Appeal No. 2005-1988 Application No. 09/822,651 examiner also states that Wessels discloses a molded fastener wherein a synthetic resin encapsulates the substrate, as shown in Figs 4A-4F. The examiner’s position is that this results in a polymer melt entangled with a fibrous surface of the web. We agree. Beginning on page 23 of the brief, appellants argue that replacing Wessels’ polymeric web with the nonwoven fibrous web of Allen is not a proper combination because there is no reasonable expectation of success. Appellants argue that Wessels describes the need for the polymeric material of the hooks to encapsulate the substrate. Appellants argue that in contrast, the elastomeric backings of Allen are generally described as films, with no specific need for openings that would allow encapsulation as discussed in connection with Wessels. As a result, appellants submit that the asserted modification of Wessels using the substrate of Allen would not reasonably be expected to form a successful product. In response, on page 12 of the answer, the examiner states that Allen teaches that a composite female component of the fastening device for the use in diapers comprising a non-woven fibrous web joined to an elastic backing, provides a low cost loop fastening material, instead of conventional knit or woven fabric. The examiner relies upon this teaching for the motivation to combine with Wessels. -19-Page: Previous 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 NextLast modified: November 3, 2007
