Appeal No. 1997-0926
Application No. 08/552,045
may be applied as a coating to the inside of the blood bag or3
that vitamin E is "lubricous" or useful as a lubricant.
Rather, as correctly pointed out by appellants (brief, page
4), Valentine teaches the addition of vitamin E to increase
blood component stability of blood stored in a blood bag that
is essentially free of plasticizers. We can perceive no
teaching in Valentine that the addition of vitamin E would
have any beneficial effect on the stability of blood stored in
a conventional PVC blood bag, which contains plasticizers,
such as taught by Yoshida. Absent the disclosure of the
present application, it is our opinion that one of ordinary
skill in the art would not have been motivated to modify the
blood bag of Yoshida in the manner urged by the examiner so as
to arrive at the subject matter set forth in appellants’
independent claim 1 on appeal.
For the reasons set forth above, the rejection of claim 1
under 35 U.S.C. § 103 based on Yoshida and Valentine is
reversed.
Consistent with the specification, we construe the verb "coat" to mean3
"2. To cover with a layer, as of paint." Webster's II New Riverside University
Dictionary,(1984).
