               PATENTING BY ORGANIZATIONS

       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.
