examiner, Jackson indicates that his composition is effective for
removing not only rosins and other flux materials, but also
organic compounds such as oil, grease, lubricants, plasticizers,
etc. Jackson, column 4, lines 34-44. One of ordinary skill in
the art would have reasonably understood such materials as

- column 2, line 6 (alluding to the fact that aqueous cleaners
are typically not effective as electronic component defluxing
solvents and that there is a need for a solvent which removes
organic flux residues and other organic materials without
creating a negative environmental impact).
Appellant further argues, essentially, that appellant’s
system for removing insoluble organic materials is performed by a
