Appeal No. 1999-0602
Application 08/469,393
from each of the respective SQUIDs as claimed, the fact that they are connected in series
and/or serial-parallel combinations also provides the combining feature of claim 15.
Moreover, the overall aim as set forth at the top of page 2 of the translation of Yokozawa’s
invention is to provide a flux meter capable of very high sensitivities of magnetic flux signal
strengths. Even the prior art at page 2 of this translation indicates that it was known in the
art to use closed loop-shaped magnetic flux transmitting circuits, which would have also
aided in the distribution of the incident electromagnetic radiation of claim 15 on appeal,
notwithstanding the examiner’s additional reliance upon the structure of Figure 7 of
Yokozawa to meet this feature. The top of page 4 of the translation even indicates
generally that "[i]n any application, the number and arrangement of the impedance of the
SQUID assembly are selected so that the noise index of the amplifier of the latter stage
may be minimum [minimized]." Thus, the manner and arrangement as well as the number
of SQUIDs may be selected for a given application as argued by the examiner at the top of
page 3 of the final rejection.
The focus of appellant’s arguments relate to the feature of providing "a minimum

detectable magnetic field sensitivity of about 3 x 10 T over a bandwidth from DC to
