Appeal No. 2000-1711 Application 08/808,870 We agree with appellants that Metroka does not teach or suggest the limitations of claim 13. Limitations in the claim cannot be ignored. Since Metroka does not send messages input by a character display and selection control, it does not teach encoding a message as a series of sounds. We also agree that "could have" is not the test for obviousness. See In re Mills, 916 F.2d 680, 682, 16 USPQ2d 1430, 1432 (Fed. Cir. 1990) ("While Mathis' apparatus may be capable of being modified to run the way Mills' apparatus is claimed, there must be a suggestion or motivation in the reference to do so."). The examiner has failed to establish a prima facie case of obviousness. The rejection of claims 13, 14, 26, and 27 is reversed. CONCLUSION The rejection of claims 1, 3-12, 15-25, 28, and 29 is sustained. The rejection of claims 2, 13, 14, 26, and 27 is reversed. No time period for taking any subsequent action in connection with this appeal may be extended under 37 CFR § 1.136(a).
