Patenting By Organizations Top Ten Companies Calendar Year 1991 This report, prepared from the Technology Assessment and Forecast (TAF) data base, shows, for U.S. utility patents granted in calendar year 1991, the ten organizations which received the most patents. 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 (e.g., ESSO to EXXON) have been merged into a single name. 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.
