                                 Patenting Trends
                                Calendar Year 2000

    In calendar year 2000, the U.S. Patent and Trademark Office granted a
    record number of patent documents including 157,497 utility, 17,414
    design, 548 plant, and 524 reissue patents, and 104 statutory invention
    registrations for a total of 176,087 patent documents for the year.
    Annual grants of all patent documents increased by 4.1 percent over the
    total for calendar year 1999 (169,147 grants in 1999). Calendar year
    2000 grants of utility patents (`patents for inventions') increased by
    2.6 percent over the total for 1999 (153,486).

    In 2000, the share of all patents that were issued to U.S.-resident
    inventors was 55.1 percent, down from the 55.6 percent U.S. share for
    1999. California-resident inventors claimed a 20.5 percent share
    (19,845 patents) of these U.S.-resident inventor patents, followed by
    resident inventors from New York (7.3 percent, 7,036 patents), Texas
    (7.0 percent, 6,789 patents), Illinois (4.7 percent, 4,514 patents),
    and New Jersey (4.5 percent, 4,399 patents). U.S.- resident inventors
    of the following areas had large percentage increases in patent receipts
    from 1999 to 2000: Nebraska, North Dakota, Idaho, South Dakota, Wyoming,
    and Vermont.

    There were 20,352 patents granted to U.S. independent inventors in 2000,
    slightly fewer than the 1999 count of U.S. independent inventor patents
    (20,540). The independent inventor share of all patents issued to
    U.S.-resident inventors in 2000 was 21.0 percent, down from a 21.8
    percent share in 1999.

    Foreign-resident inventors claimed a 44.9 percent share of all U.S.
    patents issued in 2000. The share of all U.S. patents that were issued
    to Japan-resident inventors in calendar year 2000 was 18.7 percent, down
    from 19.2 percent in 1999 and 19.7 percent in 1998.  The 2000 share of
    U.S. patents that were issued to Germany-resident inventors was 6.1
    percent, up from a 5.9 percent share for 1999.

    In 2000, the number of patent grants to Taiwan residents increased by a
    substantial 28.3 percent over the total for 1999. Among the countries
    whose residents received the most U.S. patents, Italy and Sweden also
    displayed large increases in the number of patents granted to their
    residents while South Korea and Japan displayed modest declines. Other
    countries with large percentage increases in annual patent receipts for
    2000 include People's Republic of China,  Singapore, Argentina, and
    Ireland.

    The eleven foreign countries whose residents received the most U.S.
    patents during calendar year 2000 are displayed in the table below.
    Following that table is a table that lists states and countries and the
    percentage change in patenting by their residents from 1999 to 2000.
