Application 08/036,648
This is an appeal under 35 U.S.C. § 134 from the
examiner's refusal to allow claims 19 through 26, all the
claims remaining in this application.
THE INVENTION
The appealed subject matter is directed to a "dosage
form" for administering drugs which is specially configured
for delayed delivery of a drug. The "dosage form" includes
(1) a drug composition comprising a dose of a particular type
of drug and a polymer having particular viscosity properties
which polymer permits or prevents the delayed release of the
drug and (2) a drug-delayed delivery composition comprising a
polymer of a particular molecular weight which forms part of
the wall material of the "dosage form" and aids in delaying
the rate of passage of fluid through the wall material. The
appealed subject matter also includes a method of delayed
delivery of a drug to a patient by giving the patient the
above-described "dosage form".

subject matter and is reproduced below for a more facile
