1 The examiner’s answer contained two new grounds of rejection against
claims 11-17 and 19-24 under 35 U.S.C. § 112, second paragraph. The examiner
considered the language “ceramic color layer” to lack antecedent bases in claim 11 and
that the language “optically inactive” as indefinite. In response thereto, applicants
amended claim 11, lines 2-3 to recite “at least one decorative ceramic color layer” and
amended claim 11, lines 5-6 to delete the expression “optically inactive” . Applicants
additionally pointed out that claims 12-17 and 19-24, also subject to the new grounds of
rejection, did not contain the language “optically inactive” Upon consideration of the
amendment, the examiner indicated that the amendment would be entered and that the
new grounds of rejection were withdrawn. Accordingly, claim 11, as presented in this
decision, includes the aforementioned amendments.
