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.

Unless noted, 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.
