Appeal 1997-1635
Application 08/319,667
17. Upon repeating the process using dodecylbenzene-
sulfonic acid, along with the amine, applicants tell us that
even after 48 hours "there was no solid deposit in the bottom"
of the column.
18. Example 2 is similar to Example 1. The use of7
an amine (again aminoguanidine bicarbonate) in combination
with various organic sulfonic acids is said to reduce the
amount of deposits from 400 mg (sans organic sulfonic acid) to
10 to 70 mg (depending on the organic sulfonic acid used).
The examiner's rejection
19. The examiner has rejected claims 1-10 as being
unpatentable under 35 U.S.C. § 103(a) over "Japanese Patent
'438 with or without Applicants' Disclosure of Admitted Prior
art as illustrated by EP-A-270999 and JP-A 117 716/75"
(Examiner's Answer, page 3).
20. Using our own somewhat amateur archeological
skills, we have unearthed what we think is the meaning of:
(1) Japanese Patent '438,
(2) EP-A-270999 and
The archeology is less complicated with respect to Example 2; it refers to only7
two German patent documents.
