Appeal 2006-2801
Application 09/989,684
Appellants' invention is directed to an optical disc for separating
disperse particles from particle agglutinants. Representative claim 77, as
presented in the Brief, is reproduced below:
77. An optical disc for separating disperse particles from particle
agglutinants, comprising:
a plurality of tracks disposed on an outer periphery of the optical disc;
a main chamber disposed between at least a portion of the plurality of
tracks and a light detector, the main chamber comprising:
an entry chamber configured to accept a sample; and
a separation structure comprising solid components spaced apart to
form gaps, the gaps being large enough to allow disperse particles to change
position relative to the center of the disc by passing through the separation
structure, the gaps being too small to allow particle agglutinants to pass
through the separation structure;
wherein a quantity of disperse particles may be determined by using
the light detector to count a number of the plurality of tracks that are covered
by the disperse particles.
The prior art relied upon by the Examiner in rejecting the claims on
appeal is:
Virtanen US 6,030,581 Feb. 29, 2000
The Examiner has entered the following grounds of rejection:
I. Claims 9, 12, 25-31, 77, and 78 are rejected under 35 U.S.C.
