Purpose
The Office of Advocacy has a long-standing interest in questions
about the burden small firms must bear to protect their intellectual
property. The globalization of technology has made it even more
necessary for small firms to have patent protection so that they
will be able to finance research and development costs and still
make a profit.
This research identified differences in foreign patenting by small
and large firms. The objective was to determine whether small
firms working in the same technological fields as large firms,
with inventions of comparable value, are able to patent their
inventions as broadly as large firms or are inhibited by resource
constraints or other obstacles.
The findings of the research will be relevant to U.S. government
policy and programs aimed at increasing exports and to international
patent treaty negotiations.
Scope and Methodology
To compare foreign patenting practices of small and large businesses,
a data set of matched pairs of small and large business patents
was constructed. All U.S. patents issued to small firms in 1988
were matched to randomly selected large business patents in the
same technology field issued on or about the same date. Patents
were selected from two lists supplied by the United States Patent
and Trademark Office. Searches of other public data bases provided
information regarding the patent. Information collected included
the application date, issue date, title and abstract, the U.S.
Patent Classification (USPC), the International Patent Classification,
and references to earlier patents. The result was a final set
of 2,751 matching pairs of U.S. small and large business patent
families.
The number of countries in which protection was sought for an
invention was measured by a variable called "patent family
size" and was calculated by counting the number of countries
represented by patent applications and awards in the family.
The number of times any particular patent was cited in applications
for other patents was used to assess the value of each patent.
The USPC classification system has 400 categories; for this study,
all patents were aggregated into 13 broad technology areas. Standard
statistical techniques were used to identify statistically significant
findings. The researchers also interviewed the principals in eight
firms to explore the differences in foreign patenting behavior
among small firms.
