    calendar year.

    For the ninth consecutive year, International Business Machines
    Corporation (IBM) ranks first among non-Federal patenting
    organizations. IBM received 3,411 utility patents for the year, up 18
    percent from its total for the year 2000. The top ten patenting
    organizations for 2001 consist of two U.S. corporations, seven Japanese
    corporations, and one corporation from the Republic of Korea.

    NEC Corporation remains in second position with 1,953 patents and Canon
    Kabushiki Kaisha remains in third position with 1,877 patents. After
    joining the top ten list for the first time last year, Micron
    Technology, Inc. continued to increase its patent activity jumping to
    fourth position with 1,643 patents.

    Matsushita Electric Industrial Co., Ltd., Hitachi, Ltd, and Mitsubishi
    Denki Kabushiki Kaisha have joined the top ten list for 2001 while
    Lucent Technologies Inc., Toshiba Corporation, and Motorola, Inc. have
    fallen out of the list of top ten patenting organizations.

    The U.S. Government received 954 utility patents for the year which
    would rank it sixteenth among the top patenting organizations for 2001.

    * The  listed patent counts are preliminary counts which are subject to
      correction. The final listing of patent counts for the top patenting
      organizations in 2001 should be available by early April.

    Please Note:
    Patent information presented reflects patent ownership at patent grant
    and does not include ownership changes that occur after the patent grant.
    Where more than one assignee (owner) 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 to report data by a single
    organization name, achievement of a totally clean record is not expected,
    particularly in view of the many variations that occur in corporate
    identifications.
