Patenting Trends
                        Calendar Year 1994


In calendar year 1994, the total number of patents granted by the
U.S. Patent and Trademark Office increased by 3.5 percent to a
record 113,706, including utility, design, plant, and reissue 
patents and statutory invention registrations.

U.S. resident inventors showed vigorous patenting activity for the
year.  For the sixth consecutive year,  the share of all patents
which were granted to U.S. resident inventors increased.  In 1994,
56.6 percent of all patents (64,349 patents) were issued to U.S.
resident inventors, up considerably from the 55.7 percent share
obtained by U.S. resident inventors in 1993.  The share of patents
granted to foreign resident inventors fell to 43.4 percent in 1994.

The share of all U.S. patents which were issued to inventors
residing in Japan was 20.7 percent  in 1994 (23,517 patents), down
from the 21.3 percent share in 1993.  The share of all U.S. patents
which were issued to inventors residing in Germany was also down,
to 6.1 percent (6,989 patents) in 1994 from 6.5 percent in 1993.

The number of all patents granted to U.S. independent inventors
increased by 2.7 percent from 1993 to 1994. The share of patents
which were granted to U.S.independent inventors, however, decreased
from 14.7 percent of all patents in 1993 to 14.5 percent in 1994. 
If only patents for inventions (i.e., utility patents) are
considered, U.S. independent inventor performance appears
considerably stronger with the number of patents granted to U.S.
independent inventors increasing by 4.3 percent from 1993 to 1994
and the share of patents for invention which were obtained by U.S.
independent inventors increasing from 12.5 percent in 1993 to 12.6
percent in 1994.

The ten foreign countries which received the most patents during
CALENDAR YEAR 1994 are shown below. In general, only slight changes
in ranking will occur from one year to the next. The  emergence of
both China (Taiwan) and South Korea on this list highlights the
growing importance of the Pacific rim region in the patenting
arena.
