Appeal No. 97-0345
Application 08/363,094
with a quarter wave plate, as illustrated in Figure 16,
element 164.
The independent claim 48 is reproduced as follows :2
48. An absorption spectroscopy device, comprising:
a laser diode emitting laser radiation;
a quarter wave plate; and
a sample cell containing a volume of material to be
analyzed, said laser radiation emitted from said laser diode
passing through said quarter wave plate before passing through
said sample cell.
The Examiner relies on the following references:
Mulready et al. (Mulready) 3,699,471 Oct. 17,
1972
Sato et al. (Sato) 4,963,004 Oct. 16,
1990
Ritter et al. (Ritter)
(European Patent Application) 0 176 329 Apr. 2, 1986
Claims 48 through 59 stand rejected under 35 U.S.C. § 103
as being unpatentable over Mulready and Ritter in view of
Sato.
The claims in Appellants’ appendix are correct except that claim 56 is2
dependent from claim 55 instead of claim 50 as indicated.
