Hatch-Waxman Related Provisions of the Medicare
Prescription Drug Bills (H.R. 1 and S. 1): A Side-by-
Side Comparison
Summary
The Congress is currently debating changes to the Medicare program. H.R. 1,
the Medicare Prescription Drug and Modernization Act, and S. 1, the Prescription
Drug and Medicare Improvements Act, as passed by each respective body on June
27, 2003, contain provisions that would amend P.L. 98-417, the Drug Price
Competition and Patent Term Restoration Act of 1984 (commonly known as the
Hatch-Waxman Act). The Hatch-Waxman Act made several significant changes to
the patent laws designed to encourage innovation in the pharmaceutical industry
while facilitating the speedy introduction of lower-cost generic drugs. The two bills
currently under consideration would address Hatch-Waxman related issues of drug
patents listed in the Orange Book, patent challenges by generic firms, and the award
of market exclusivity, among other things. This report provides a thematic side-by-
side comparison of the proposed changes contained in H.R. 1 and S. 1 that would
affect the Hatch-Waxman legislation. The paper will be updated as events warrant.

S. 1): A Side-by-Side Comparison
Introduction
The Congress is currently debating changes to the Medicare program.1 H.R. 1,
the Medicare Prescription Drug and Modernization Act, and S. 1, the Prescription
Drug and Medicare Improvements Act, as passed by each respective body on June
27, 2003, contain provisions that would amend P.L. 98-417, the Drug Price
Competition and Patent Term Restoration Act of 1984 (commonly known as the
Hatch-Waxman Act).
The Hatch-Waxman Act made several significant changes to the patent laws
designed to encourage innovation in the pharmaceutical industry while facilitating
the speedy introduction of lower-cost generic drugs. However, over the 18 years
since its passage, concerns have been expressed as to whether or not implementation
of certain portions of the law has led to unintended consequences contrary to the
original intent. Some argue that brand name companies and/or generic firms have
exploited provisions of the Act to prevent the timely marketing of less costly
pharmaceuticals. Other experts maintain that while a few isolated cases of
“misinterpretation” of the law have arisen, these can be addressed through existing
procedures and that legislative changes are not necessary.2
The two bills currently under consideration would address Hatch-Waxman
related issues of drug patents listed in the Orange Book, patent challenges by generic
firms, and the award of market exclusivity, among other things. The following is a
thematic side-by-side comparison of the proposed changes contained in H.R. 1 and
S. 1 that would affect the existing Hatch-Waxman legislation.

pharmaceuticals
P.L. 98-417, commonly known as the
“Hatch-Waxman Act,” modified the
1952 Patent Act by creating a statutory
exemption from certain claims of
patent infringement. Generic
manufacturers may commence work
on a generic version of an approved
brand name drug during the life of the
patent, so long as that work furthers
compliance with Food and Drug
Administration (FDA) regulations.
Although the Hatch-Waxman Act
provides a safe harbor from patent
infringement, it also requires would-be
manufacturers of generic drugs to
engage in a specialized certification
procedure. The core feature of this
process is that a request for FDA
marketing approval is treated as an
“artificial” act of patent infringement.
This feature was intended to allow
judicial resolution of the validity,
enforceability and infringement of
patent rights afforded by the Patent
and Trademark Office.

H.R. 1
S. 1
Under PL 98-417, each holder of an
approved new drug application (NDA)
must list pertinent patents it believes
would be infringed if a generic drug
were marketed before the expiration of
these patents. The FDA publishes this
list of patents in its list of approved
products, the “Orange Book.”
A generic firm must certify its
intentions with regard to each patent
associated with the generic drug it
seeks to market. Four possibilities
exist under the 1984 Act: (1) that
patent information on the drug has not
been filed; (2) that the patent has
already expired; (3) the date on which
the patent will expire; or (4) that the
patent is invalid or will not be
infringed by the manufacture, use or
sale of the drug for which the
“abbreviated new drug application”
(ANDA) is submitted.
These certifications are respectively
