The Insufficiency of Antitrust Analysis for Patent Misuse

Patent Misuse
ROBIN C. FELDMAN*
Patent misuse lies at the intersection of patent and antitrust law. The
history and conceptual overlap of patent law and antitrust law have left
the doctrine of misuse hopelessly entangled with antitrust doctrines. In
response, a number of scholars and legislators have argued for streamlin-
ing the patent misuse inquiry by applying antitrust rules.' Current court
decisions have moved in this direction as well.'
The notion of applying antitrust rules to test for patent misuse has
an appealing logic. Patent misuse can be defined as an improper attempt
to expand a patent. Antitrust principles, among other things, restrict the
improper expansion of monopolies. Shouldn't courts be able to use anti-
trust rules to identify an improper expansion of a patent monopoly?

Misuse Doctrine Obsolete?, 110 HARV. L. REV. 1922, I939 (1997) (arguing that although the substantive
test for misuse should be subsumed under an antitrust analysis, the relaxed standing requirements of
misuse should be maintained); but see Louis Kaplow, The Patent-Antitrust Intersection: A Reappraisal,
97 HARv. L. REV. 1813, 1818-20 (1984) (arguing that neither patent nor antitrust law should reign su-
preme and suggesting that courts should determine whether a patentee's practice is acceptable by cal-
culating a ratio that compares (I) the patentee's marginal reward over the optimal patent reward to
(2) society's marginal monopoly loss in the case of that practice).
