The examiner states that Spitsberg’s “50 volume percent of the layer...is considered to fall within the 40-60 [weight] % range for both the BSAS and the zirconia” of claim 35 (Answer, page 8). In response, appellants point out the different unit proportions (volume % vs. weight %) and argue that the examiner “still does not address how Spitsberg et al. ‘814 teaches or suggests the claimed relative weight proportions of CMAS-reactive material and ceramic thermal barrier coating material” (Reply Brief, page 8). The examiner’s above quoted statement is speculative since it is not supported by any analysis or evidence that shows Spitberg’s 50 volume percent of BSAS falls within the claim 35 range of “from about 40 to about 60 [weight] % of a CMAS- reactive material” (i.e., BSAS). Thus, we find that the appeal is not ripe for resolution of all the issues on appeal before us. In responding to this remand, the examiner must choose at least one of the following options: Option No. 1: Provide the appeal record with evidence disclosing properties such as densities of BSAS and YSZ -3-Page: Previous 1 2 3 4 5 6 7 NextLast modified: November 3, 2007
