Appeal 2007-2888
Application 11/017,602
Claims 1-5 and 7-18, which are all the pending claims, are appealed
(Appeal Br. 1). The following rejections are on appeal:
1) Claims 1, 2, 17, 18 stand rejected under 35 U.S.C. § 102(b) as
anticipated by Sloan (U.S. Pat. No. 5,779,193, Jul. 14, 1998) (Answer 3).
2) Claims 3-5 and 7-181 stand rejected under 35 U.S.C. § 103(a) as
obvious over Sloan in view of Yoerkie (U.S. Pat. No. 6,260,660 B1, Jul. 17,
2001) or Allen (U.S. Pat. No. 4,056,161, Nov. 1, 1977) (Answer 5).
We select the following claims as representative for the purpose of
deciding the issues in this appeal:
1. An acoustic absorption system for an airframe section
comprising:
a foam portion which provides an interference fit between a multitude
of airframe frame members.
7. An airframe section comprising:
an airframe component having a multitude of frame members which
define a void; a foam portion which provides an interference fit with said
multitude of frame members; and a mass barrier layer mounted to said
multitude of frame members.
9. The airframe section as recited in claim 7, wherein said mass
barrier layer includes a vinyl which is mass loaded with a barium sulfate
powder.
13. The airframe section as recited in claim 7, wherein said mass
barrier layer is adhered to said foam portion and said multitude of frame
members.
17. The acoustic absorption system as recited in claim 1, wherein
said foam portion is sized to be force fit between said multitude of frame
members.
1 The rejection lists claim 6 as rejected; however, claim 6 was canceled by
an amendment dated Jan. 31, 2006, which was entered by the Examiner. See
Advisory Action dated Jun. 21, 2006.
