General Description of the Report
This report, prepared by the United States Patent and Trademark Office (USPTO), Office
of Information Dissemination Services, summarizes the patenting activity of U.S. colleges,
universities, and associations composed of U.S. colleges and universities
obtaining utility patents (i.e., 'patents for inventions') during calendar
years 1969-2000.
Several statistical tables are provided that display the patent activity for all
U.S. college and university institutions. Other statistical tables display the
patent activity for each U.S. college and university institution ranked in the
top 100 by total research and development (R&D) expenditures in fiscal year (FY) 1999.
Academic institutions ranked in the top 100 for R&D expenditures in FY 1999 were
identified from the National Science Foundation report, Academic Research and
Development Expenditures, Fiscal Year 1999 (early release Tables).
Patent data presented in this report have been obtained from the USPTO Technology
Assessment and Forecast (TAF) database. The TAF database is maintained by the
Office of Information Dissemination Services and contains selected bibliographic
information from patents that have issued since 1963.

Selection of Academic Institutions
Academic institutions that appear in this report consist of U.S. colleges,
universities, and associations of U.S. colleges and universities that were
assigned one or more U.S. utility patents between calendar years 1969 and 2000.
The selection of academic institutions is based on a search of patent assignee
names that appear in the Technology Assessment and Forecast database assignee file.
The assignee file is an alphabetical listing of more than 200,000 names of assignees
whose names appear on the printed patents.
Only the first-named assignee on a patent is contained in the TAF database. This
eliminates double counting of patents when distributions are based on assignee name.
Thus, a search of patents assigned to academic institutions excludes patents with a
first-named assignee that is not an academic institution, but with a second assignee
that is a U.S. academic institution.
A comprehensive list of institutions selected for inclusion in this report is presented
in alphabetical order in the attachment titled, 'Alphabetical Listing of University Assignees
With Total Patent Counts For the Period' (Table of Contents, section 1C). Academic institution
entries that are included in this
report for the first time this year are shown below. Some of these institutions (e.g.,
CLEMSON UNIVERSITY RESEARCH FOUNDATION) may be components of larger academic
institutions or systems that appear elsewhere in the report (e.g., CLEMSON UNIVERSITY):
- UNIVERSITY OF MASSACHUSETTS WORCESTER
- CLEMSON UNIVERSITY RESEARCH FOUNDATION
- COLLEGE OF WILLIAM & MARY
- ERSKINE COLLEGE
- HAMPSHIRE COLLEGE
- NORTH SHORE-LONG ISLAND JEWISH RESEARCH INSTITUTE
- NORTHWEST MISSOURI STATE UNIVERSITY
- PITTSBURG STATE UNIVERSITY
- SAINT LOUIS UNIVERSITY, HEALTH SERVICES CENTER, RESEARCH ADMINISTRATION
- TROY STATE UNIVERSITY
- UNIVERSITY OF COLORADO, UNIVERSITY TECHNOLOGY CORPORATION
- UNIVERSITY OF NEW ORLEANS FOUNDATION
- UNIVERSITY OF THE SCIENCES IN PHILADELPHIA
- VALDOSTA STATE UNIVERSITY
Careful consideration should be given to the use of patent data to assess the
inventive activity of a particular component of a larger institution or statewide
system. A search of patents assigned to the University of California--Los Angeles,
for example, might result in the identification of several patents with that
assignee name. However, the assignee name that appears on other patents associated
with the UCLA campus might simply show University of California. This situation
occurs when the patent applicant or legal representative, who is responsible for
providing the assignee name that appears on the patent, variously provides the name
of the statewide system, a particular campus, or a foundation, institute, etc. within
a college or university.
The lack of consistency in the format of assignee names can also pose a problem
identifying patents associated with colleges and universities ranked in the top 100
according to R&D expenditures in FY 1999. The top 100 institutions in the NSF survey
are not necessarily ranked according to statewide systems. For example, the University
of California - San Diego was ranked 6th in R&D expenditures in FY 1999 and the University
of California - Los Angeles was ranked 4th, according to NSF figures. As noted above,
it is not always possible to associate patents with a specific campus or research center
separately from the larger institution or statewide system to which it belongs. For purposes
of this report, the R&D expenditures at all campuses of a given institution were consolidated
into a single figure. Similarly, all patents associated with a given institution, its
various campuses, known research centers, foundations, or institutes that are integral units
of that institution were consolidated into a single patent count. No attempt
is made to provide total patent counts for specific campuses or research facilities,
and where they do appear, those figures should not be considered the total patent count
for those campuses or research facilities.
Identification of Top 100 Institutions in R&D Expenditures
Academic institutions in the top 100, based on R&D expenditures in fiscal year 1999,
are derived from National Science Foundation report, Academic Research and
Development Expenditures, Fiscal Year 1999 (early release tables, Table 32).
This NSF report, based on NSF's fiscal year 1999 Survey of Research and
Development Expenditures at Universities and Colleges, depicts science and
engineering expenditures for separately budgeted research and development at
academic institutions:
The term 'separately budgeted R&D expenditures' includes all funds expended
for activities specifically organized to produce research outcomes and
commissioned by an agency either external to the institution or separately
budgeted by an organizational unit within the institution. 'Expenditures'
are funds actually spent by an institution during its fiscal year.
The names of academic institutions in the NSF report are shown in a table, 'Total R&D
Expenditures at U.S. Colleges and Universities: Top 100 Institutions in R&D Expenditures
in Fiscal Year 1999', available elsewhere in this patent report (Table of Contents section
(1E)). The NSF report provides a ranking
that includes specific campuses of statewide systems, such as the University of California
at San Diego (U CA San Diego), which is ranked 6th in R&D expenditures in 1999.
However, it is not always possible to identify the patents associated with a specific
campus; frequently, the name of a larger institution or statewide system-not a specific
campus--appears as the assignee name on a U.S. patent. For example, a patent assigned
to the University of California may or may not be associated with the San Diego campus.
For some academic institutions in the NSF top 100, only patent counts for larger
institutions or statewide systems can be provided.
The table, 'Total R&D Expenditures at U.S. Colleges and Universities: Top 100 Institutions
in R&D Expenditures in Fiscal Year 1999' (table 1e in the Table of Contents) shows the
assignee names on U.S. patents that most closely correspond to the academic institutions in
the NSF top 100, and for which patent counts are provided in this section. No attempt
is made to provide total patent counts for specific campuses or research facilities,
and where they do appear, those figures should not be considered the total patent count
for those campuses or research facilities.
Database Records
The TAF database includes bibliographic data items for 3.0 million U.S. utility patents
issued since 1963 and 210,000 non-utility patents issued since 1977. While every effort
is made to ensure accurate data for all patents, the size and complexity of the database
prevent achievement of a totally "clean" record. The following points are noted.
- A foreign origin patent in this report is a patent [assigned to an academic
institution at the time of issue] with a first-named inventor who resided in a
country other than the United States.
- Patents assigned to U.S. academic institutions are considered U.S. corporate
owned. Patents in this report that are classified as government, foreign corporate,
foreign government, or individually owned patents are the result of errors in the
patent record.
- Patent classification information in this report reflects the U.S. Patent Classification
System (USPC) as it existed on 31 December 2000. At the time of issue, each patent is
classified into one or more USPC classes of technology--the first class listed is known
as the primary class (called the "ORIGINAL" class, in USPTO specific terminology).
Frequent expansion and changes occur in the USPC to accommodate changing
technologies. As a result, a patent may be periodically
reclassified into a new class. Thus, the current, primary class associated with a
patent may change over time and may not be the same class assigned at the time of issue.
The distribution of patents by class in this report is based on the primary class,
as of 31 December 2000.
Distribution of Utility Patent Data By Year of Grant and By Year of Patent Application
In many of the tables in this report, patent data are distributed by the year in which the patents
were granted. In addition, many tables distribute patent data by the year in which each granted patent
was filed (i.e., the year of patent application).
Distributing patent grants by the year in which they were filed can be useful in analyses
of patent activty, It should be noted, however, that DATA FOR THOSE APPLICATIONS WHICH WERE FILED BUT
NEVER ISSUED (ROUGHLY 25% OF TOTAL FILINGS) ARE NOT INCLUDED IN ANY TABLES IN THIS REPORT.
Data displaying patents as distributed by their year of application are of significant value since
the date an application was filed more accurately reflects when the technology was developed.
Additionally, fluctuations in patent data distributed by application date are much more likely to
reflect changes in technological activity, since such fluctuations would for the most part be immune
to changes in U.S. Patent and Trademark Office (USPTO) processing such as occurred in years such as 1986
when the USPTO issued fewer patents than would normally have been expected due to a lack of funds to
print patents. Note that a patent's "pendency" can be quite variable from one patent to another thereby
affecting the date of patent grant. Such variation in pendency is determined by many factors, including
USPTO workload (which varies between technologies), budget and manpower levels, patent printing schedules,
etc.
Since the average time period between filing for a patent and the issuing of the patent (i.e.,
a patent's "pendency") is about 24 months, the data in these tables for 1997 - December 2000 are
incomplete. This is because a significant number of the applications filed from 1997 - December 2000
which will ultimately become patents were still pending in December 2000. Since they had not yet
become patents as of December 2000, they are not included in these tables.
As of 12/31/2000, utility patent application data were approximately 99% complete for patent applications
filed in 1997, 61% complete for 1998 filings and 19% complete for 1999 filings. They were essentially
complete for applications filed prior to 1997.

Summary
In calendar year 2000, the USPTO issued 157,495 utility patents, of which 3,087 (2.0%) were assigned
to a U.S. college, university or association of U.S. colleges and universities. While both the
number and percent of total patents assigned to U.S. academic institutions generally have shown a steady
increase since 1985 (when only 589 utility patents, or 8% of the total, were assigned to U.S.
academic institutions), the number and percent dropped in 2000 as compared to the figures for
1999 (3,340 patents and 2.2% of the total). The 3,087 patents assigned to U.S. academic
institutions in 2000 represent 4.4% of the 70,884 patents assigned to non-government, U.S. organizations.
(See the table titled, 'Number and Percent of Total Utility Patents, and of U.S. Corporate-Owned
Utility Patents,' Table of Contents section (1B))
Institutions that received higher numbers of utility patents in 2000 were the University of
California (432 patents), followed by Massachusetts Institute of Technology (113 patents),
and Stanford University and the California Institute of Technology (both with 103 patents).
The University of California and the Massachusetts Institute of Technology were also the
top two recipients of utility patents in 1998 and 1999.
Technologies that have been emphasized in patenting by U.S. colleges and universities include
biotechnology, and pharmaceuticals. In the year 2000, disproportionately
more patents assigned to U.S. academic institutions were in the following classes of
technology:
- Class 530 - Chemistry: Natural Resins or Derivatives; Peptides or Proteins;
Lignins or Reaction Products Thereof
- Class 435 - Chemistry: Molecular Biology and Microbiology
- Class 800 - Multicellular Living Organisms and Unmodified Parts Thereof and Related Processes
- Class 436 - Chemistry: analytical and Immunological Testing
- Class 424 - Drug, Bio-Affecting and Body Treating Compositions (includes Class 514)
- Class 532 - Organic Compounds (includes Classes 532-570)
