Appeal 2007-2190
Application 10/229,489
during fluoroscopically guided interventional surgery procedures. (Br. 2).
Claim 18 is illustrative of the invention and is reproduced below:
18. A film media sensitive to low energy x-rays comprising a first
support layer of polymeric film which is permeable to low energy x-rays
from about 20ke V to 120ke V and a second layer thereon of a composition
comprising a microcrystalline dispersion of a substantially crystalline image
receptive polyacetylenic compound and selected from the group consisting
of pentacosa-10, 12-diynoic acid; tricosa-10, 12-diynoic acid, heneicosa-10,
12-diynoic acid and combinations thereof and a compound that selectively
absorbs incident low energy photon radiation which is a metal halide and is
selected from the group consisting of cesium halides and rubidium halides
and which further comprises a chelating agent.
The Examiner relies on the following prior art reference to show
unpatentability:
Patel US 5,420,000 May 30, 1995
The Examiner made the following rejection1:
Claims 4 and 8-18 under 35 U.S.C. § 102(b) as anticipated by Patel.
Appellants’ traversal of the anticipation rejection is limited to their
contention that Patel fails to disclose or suggest a compound which
possesses the property of selectively absorbing incident low-energy photon
radiation. (Br. 3). According to Appellants, “Patel, et al. does not disclose
the inclusion of a metal halide for this purpose which is selected from the
group consisting of cesium halides and rubidium halides. Consequently,
Patel, et al. cannot anticipate the present invention as claimed and this
rejection should not be upheld.” (Br. 3).
1 The rejection of claims 4 and 8-18 under 35 U.S.C. § 102(b) as anticipated
by Lewis has been withdrawn. (Answer 4).
