disadvantageous compared with frame by frame
synchronization."
Kametani discloses task by task synchronization. The
examiner states that "[a] 'task' as understood in the art
can be a single instruction" (EA4) and "[a] task includes
one or more instructions" (EA5). We agree that one of
ordinary skill in the pertinent art of synchronizing
processors would have had sufficient knowledge to appreciate
that the task in Kametani could be a single instruction or a
group of instructions. Obviousness is determined through
the eyes of one of ordinary skill in the art and is not
based just on the express teachings of the references.
The examiner further applies Jaswa for its teaching
that "[i]nstruction synchronism is a widely used
synchronization technique" (col. 1, lines 34-35). Jaswa
also discloses that instruction synchronization has
disadvantages in synchronizing multiply redundant computers;
however, this does not negate the teaching that instruction
by instruction synchronization was a widely used technique.
We agree with the examiner that the teaching of instruction
by instruction synchronization in Jaswa would have motivated
