Appeal No. 1997-3328
Application No. 08/226,605
Thereby, in accordance with 37 CFR ' 1.192(c)(7), claims 2-11
fall with claim 19. Thus, it follows that the decision of the
examiner to reject claims 2-11 under 35 U.S.C. ' 103 is also
reversed.
The 35 U.S.C. § 103 rejection of claim 20.
Appellants' claim 20 recites,
20. An electrophoresis device which comprises a supply
channel, which contains a sample having an original sample
composition, a drain channel, and an electrolyte channel,
which contains an electrolyte buffer, wherein said supply and
drain channels are each inclined with respect to the
electrolyte channel, and which supply and drain channels
intersect said electrolyte channel at a supply port and a
drain port, respectively, such that a geometrically defined
sample volume is defined by a section of said electrolyte
channel located between said supply port and said drain port,
which electrophoresis device further comprises a means for
electrokinetically injecting a sample which reflects the
original sample composition into said sample volume
characterized in that said supply channel and said drain
channel each have a resistance to flow with respect to said
electrolyte buffer which is about 5% lower than the respective
resistance to flow of said electrolyte channel.
Appellants' describe (with respect to Fig. 3) that "[t]he
resistance to flow of the supply and drain channel can be
deminished by either reducing the length of the respective
channels or by increasing their respective widths w"
