Appeal No. 2002-0585 Application No. 09/088,307 specification is truly enabling, In re Marzocchi, 439 F.2d 220, 169 USPQ 367 (CCPA 1971); In re Sichert, 566 F.2d 1154, 196 USPQ 209 (CCPA 1977). Moreover, if an examiner had a reasonable basis for questioning the sufficiency of the disclosure, it was incumbent on appellants to come forward with evidence, if they could, to rebut the examiner’s position. In re Buchner, 929 F.2d 660, 18 USPQ2d 1331 (Fed. Cir. 1991). In the instant case, the teaching by the specification, e.g., pages 22-24, regarding parameters k and kbasis, clearly corresponds in scope with the claimed parameters. Appellants have explained, convincingly in our view, that these parameters are merely coefficients corresponding to the proportional, derivative and integral factors in the well known equation describing the operation of a PID controller. As further explained by appellants, e.g., pages 2-4 of the reply brief, these factors are chosen in order to have the particular system operate properly, the actual determination of specific values constituting the well-known “tuning” of a PID controller, and, since each system is different, it would be useless to provide specific values for these parameters. -5–Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 NextLast modified: November 3, 2007
