about 2-4, preferably about 2.5-3. In addition to
providing efficient cleaning, this pH range is less
damaging to the cleaned surface and less irritating to
the skin than the commercially available acidic cleaners.
B. Discussion
1. Introduction
We start our analysis of the patentability of claims 1-12
and 15 over the prior art with two new grounds of rejection

for hard surfaces comprising from 1% to 15% by
weight of the total composition of a nonionic
surfactant or mixtures thereof (col. 2, lines 39-
