Top Patenting Organizations, Calendar Year 1993

This report lists the organizations receiving the most patents for
invention (i.e., utility patents) during the 1993 CALENDAR year.  The list
is prepared from the U.S. Patent and Trademark Office's Technology
Assessment and Forecast (TAF) data base.

Once again, the U.S. Government ranks first as the organization receiving
the most patents for invention in 1993, receiving 1,165 patents.  This
total is 80 patents or 7 percent more than the total count for next highest
ranking organization.

Of the top non-Federal patenting organizations, International Business
Machines Corporation ranks first as having received the most patents for
invention in 1993.  This marks the first time since 1985 that a U.S.
corporation has ranked number one.

Other U.S. organizations made a strong showing in 1993 as well, with three
U.S. corporations ranked in the top five as having received the most
patents for inventions.  This contrasts sharply with the 1992 rankings when
only one of the top five organizations was a U.S. corporation.

The top ten non-Federal patenting organizations in 1993 include four U.S.
corporations and six Japanese corporations.  The organizations are
unchanged from 1992 although Eastman Kodak Company has jumped from seventh
to fourth position and several Japanese corporations have fallen slightly
in the rankings.  A complete listing of the top eleven organizations
receiving utility patents during 1993 is shown below.

Please Note:
Patent information included in the report reflects patent ownership at
patent grant and does not include changes in ownership which occur after
the patent grant.  Where more than one assignee exists, patents are
attributed to the first-named assignee.

No attempt has been made to combine data based on subsidiary relationships.
However, where possible, spelling variations and variations based on name
changes have been merged into a single name (e.g., ESSO to EXXON).  While
every effort is made to accurately identify all organizational entities and
report data by a single organization name, achievement of a totally clean
record is not expected, particularly in view of the variations which occur
in many corporate identifications.
