they are also known to degrade during heat sterilization to aldonic acids
and formaldehyde.
In the section entitled “Summary of the Invention”, the specification indicates that
the invention provides a sterilized peritoneal dialysis solution comprising a glucose
polymer linked predominantly by "-1,4 bonds. Specification, page 4. In one
embodiment the glucose polymer linked by "-1,4 bonds is selected from D-glucitol
gluconic acid and an alkylglycoside. Specification, pages 4-5. In a further embodiment
the invention reduces maltodextrin to D-glucitol linked predominantly by "-1,4 bonds
using a solution of water and NaBH4. Specification, page 7. In another embodiment
maltodextrin is oxidized to a gluconic acid linked predominantly by "-1,4 bonds using a
solution of water and NaOCl. Specification, page 8. It is known in the art that
maltodextrin is a starch product which consists of D-glucose units linked primarily by "-
1,4 bonds.
35 U.S.C. § 103
Claims 5-22 stand rejected under 35 U.S.C. § 103(a) as obvious over

claims 5-16 based upon the indicated strengths of the cited references.
In rejecting claims under 35 U.S.C. § 103, the examiner bears the initial burden
