Appeal No. 2004-0227 Application 09/140,151 support” (col. 2, lines 40-49). The surface pattern may be a pattern of dielectric or magnetic lines (col. 3, lines 45-47). The examiner argues that “Verschuur differs from the claims by not specifically describing storing of the measured information” (answer, page 3). Instead, to read encoded information Verschuur compares variations in capacitance associated with ink patterns to stored information about similar patterns (col. 3, lines 1-5). Verschuur also differs from the appellants’ claimed invention by not being directed toward providing security information. Although, as argued by the examiner (answer, page 6), Verschuur states that information on the contents of the envelopes can be verified, this statement in the context of the contents being orders, replies or records (col. 8, lines 10-12). Verschuur does not indicate that the information can be security information. The examiner argues that it would have been obvious to one of ordinary skill in the art to include a random distribution of dielectric components in the contents of Verschuur’s envelopes and to compare measured changes in an electric field to previously stored information to provide security against forgery (answer, pages 4-5). 6Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
