In summary, this panel of the board has:
not sustained the rejection of claims 20 through 25 and 29
through 33 under 35 U.S.C. § 103 as being unpatentable over
Windle in view of Ziu '260 and either Ziu '088 or Butts; and
not sustained the rejection of claims 29 through 32 under
35 U.S.C. § 103 as being unpatentable over Windle in view of Ziu
'260 and either Ziu '088 or Butts, as applied above, further in
view of Lueghamer.
Additionally, we have remanded the application to the
examiner to consider the matter discussed above.
