- this report has been prepared with support from the National Science Foundation -
This set of drill-down tables has been prepared from the Technology Assessment and Forecast (TAF) database and displays utility patent activity (i.e., 'patents for inventions'), by assignee name (ownership), for patents having ownership assigned to U.S. colleges and universities. Counts of patents granted since 1969 are displayed in each table.
For the purposes of this report and these tables, patent assignee information is determined by the first-named assignee at the time of patent grant, as listed on the issuing patent.
Displayed patent counts in these tables are distributed by the year in which the granted patents were applied for (i.e., filed), instead of by the year the grants were issued (1). These data do not represent the number of application filings; only those filings that resulted in patent grants are counted here.
These tables are divided into three types as follows:
This table displays separate counts of utility patents (i.e., 'patents for inventions') for each university assignee name that has been associated with a U.S. college or university.
Please note that in this table, some universities may have more than one university assignee name associated with them.
This table displays separate counts of utility patents (i.e., 'patents for inventions') for each of the top 100 academic institutions ranked according to R&D expenditures in fiscal year 2002 (2).
For each university entry, this table displays a consolidated count of patents granted to all university assignee names that have been associated with that university. In some cases, patents for as many as five or more university assignee names may have been consolidated to obtain the patent counts listed for a single university in this table.
Each of these tables displays counts of utility patents (i.e., 'patents for inventions') for a university ranked in the top 100 academic institutions according to R&D expenditures in fiscal year 2002 (2).
For the university, each of these tables displays patent counts for each university assignee name that has been associated with it. A total count for all associated assignees is also provided.
DATA FOR THOSE APPLICATIONS WHICH WERE FILED BUT NEVER ISSUED (ROUGHLY 25% OF TOTAL FILINGS) ARE NOT INCLUDED IN THESE TABLES.
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 1999 - December 2003 are incomplete. This is because a significant number of the applications filed from 1999 - December 2003 which will ultimately become patents were still pending in December 2003. Since they had not yet become patents as of December 2003, they are not included in these tables.
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.
As of 12/31/2003, utility patent data, as distributed by year of filing, are approximately 77% complete for patent applications filed in 2000 and 52% complete for 2001 filings. They are essentially complete for applications filed prior to 2000.
(2) -Academic institutions in the top 100, based on R&D expenditures in fiscal year 2002, are derived from National Science Foundation report, Academic Research and Development Expenditures, Fiscal Year 2002, Table 32. This NSF report, based on NSF's fiscal year 2002 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 2002', available elsewhere in this patent report. The NSF report provides a ranking that includes specific campuses of statewide systems, such as the University of California at San Francisco (U CA San Francisco), which is ranked 6th in R&D expenditures in 2002.
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 2002' 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.
Use of spreadsheet software may facilitate analysis of the data contained in these tables. Users should note that many spreadsheet software programs (e.g., Microsoft Excel) can import these tables directly. Check the spreadsheet software documentation for details.
Some web browsers permit acceptable printing of these tables directly from the web page. Also, importing the web page into spreadsheet or word-processing software may allow a user additional flexibility for formatting the tables for printing. Check the corresponding software documentation for details.
