`
`REMARKS
`
`No claims are amended and claims l - 8, 10- 32, 36 and 37 are pending and
`
`reconsideration of those claims is requested.
`
`In an earlier office action dated Aplil 10, 2007 during this prosecution, the Examiner
`
`rejected then pending claim 1 as being unpatentable over Jones et al (US 4,831,509) in view of
`
`Wrenbeck et al (US 5,436,5390) having a filing date of August 30, 1993. In the amendment filed
`
`June 20, 2007, applicants argued that the language in then pending claim 1 (as well as claims 2,
`
`6, 12, 19, 20 28 and 33) was suppotted by the specification in US patent 5,334,876 having an
`
`Aplil22, 1992 filing date and from which the present application claims primity. In the office
`
`action of October 31, 2007, the Examiner acknowledged the claims were suppmted in the
`
`specification of the '876 patent to Washeleski et al and the rejection based on Wrenbeck et al
`
`was withdrawn. That office action states "the applicant argued that Wrenbeck et al were not
`
`p1ior art. The Examiner agrees."
`
`Claims 1, 2, 19, 28 and 30 were amended subsequent to the October 31, 2007 office
`
`action, more specifically, the amendment filed January 10, 2008 made changes to these claims.
`
`Independent claims 6, 12, and 19 have not been amended since the October 31, 2007 office
`
`action and therefore the Examiner's conclusion regarding support for these claims in the '876
`
`patent specification still applies. Those claims that were amended are still suppmted as the
`
`following claim chart shows. The additions to c1aims1, 2, 19, 28, and 30 that were made after
`
`the October 31, 2007 office action are underlined.
