Appeal No. 1999-1907
Application No. 08/690,409
of the second infrared-transparent element, the
polymer material being characterized by an infrared
transparency wherein a 10-micrometer thickness of the
polymer material is at least 95 percent transparent to
infrared energy in the 3.6-7 micrometer wavelength
range, wherein the solvent-free polymer material is
not a solvent-free epoxy and is not a solvent-free
cyanoacrylate.
20. An infrared-transparent structure,
comprising:
a first infrared-transparent element transparent
to infrared energy in the 3.6-7 micrometer wavelength
range, the first infrared-transparent element having a
first face with a first antireflective coating
thereon;
a second infrared-transparent element transparent
to infrared energy in the 3.6-7 micrometer wavelength
range, the second infrared-transparent element having
a second face with a second antireflective coating
thereon;
a layer of a solvent-free polymer material
disposed between and contacting the first face and the
second face, the polymer material comprising from
about 1 to about 4 percent by weight 3-
glycidoxypropyltrimethoxysilane, balance addition-
cured dimethyl silicone.
The examiner does not rely on any prior art to support any
of the rejections before us.
Claims 1 through 22 on appeal stand rejected under the
first paragraph of 35 U.S.C. § 112 "as containing subject matter
which was not described in the specification in such a way as to
enable one skilled in the art to which it pertains, or with
which it is most nearly connected, to make and/or use the
invention." (Examiner’s answer, pages 2-3.) Also, claims 1, 2,
