Claims 5, 7, 9, 15, 17, 19, 20, 27, and 29-33 stand rejected under 35
U.S.C. § 102(b) as anticipated by Mohr.
Claims 5-7, 14-17, 19, 20, 25-27, and 29-38 stand rejected under 35
U.S.C. § 103 as obvious over Heinmets in combination with either Sugiyama or
Hodgson.
Claim 9 stands rejected under 35 U.S.C. § 103 as obvious over Heinmets
in combination with either of Sugiyama or Hodgson, and Bio-Rad.
We affirm in part and reverse in part.
Background
Appellants’ specification discloses a method for inactivating viruses in
body fluids such as blood. In the disclosed method, a photoactive virus-
inactivating agent is added to the blood. Specific virus -inactivating agent
mentioned in the specification are “psoralens, porphyrins, dyes, such as
methylene blue, phthalocyanines, phenothiazines, hypericin, and other
compounds that are activated by light.” Page 7, line 30 to page 8, line 2. The
blood is then irradiated to activate the virus -inactivating agent and thereby
inactivate viruses in the blood. Specification, page 5. Finally, the virus-
