product-by-process claims cover an alkaline aqueous adhesive
composition which is no more than a mixture of a resole resin,
a catalyst for the resole resin (either an ester functional
curing catalyst or a carbamate), a resorcinolic resin, and a
methylene donor. In this regard, Daily’s working examples 12-
19 illustrate aqueous alkaline mixed resin compositions made4
up of the same principal components required by the appealed
composition claims. Although, as recognized by the examiner,
Daily does not expressly describe or exemplify the
specifically claimed resole curing catalysts required by
appealed claims 23 and 24 or the specifically claimed
methylene donors required by appealed claims 26 and 27, the
examiner contends that these recited materials are well known
resole curing catalysts and methylene donors , and the 5
“secondary references” to McVay, Detlefsen, and Stephan
provide factual support for the examiner’s assertions. Thus,
McVay and Detlefsen respectively teach that carbamate resole

5With respect to the claim 26 methylene donor,
methylolurea, appellants have not challenged the examiner’s
general allegation (answer, page 9) that this compound is a
well known methylene donor.
