Appeal No. 95-2950
Application No. 07/855,127
This is a decision on an appeal from the final rejection
of claims 66 through 76 and 85 through 99 which are all of the
claims remaining in the application.
The subject matter on appeal relates to a method for
increasing the resistance to biological degradation of a
cutting fluid emulsion via a bioresistant surfactant
composition (in an amount sufficient to impart bioresistant
properties) comprising succinic acid or derivatives thereof
containing at least one branched aliphatic substituent group
having at least nine carbon atoms, at least three of which are
tertiary carbon atoms. The appealed subject matter also
relates to the corresponding cutting fluid. This appealed
subject matter is adequately illustrated by independent claims
66, 85 and 99, a copy of which taken from the appellants'
Brief is appended to this decision.
The references relied upon by the examiner in the
rejections before us are:
