CA/CAplus now has more comprehensive patent assignee information
Beginning in April 2009, CA/CAplus patent records will be updated with patent assignee information as soon as it becomes available from the patent office or authority. This includes many U.S. patent applications for which assignee information is not available at the time the record is added to CA/CAplus. Patent assignee information for patent records dating back to January 2001 will be added later this year.
For more information about CA/CAplus, refer to the STN Database Summary Sheet.

USPATFULL and USPAT2 enhanced with patent assignment/reassignment information
The complete history of assignments, reassignments, and related events for U.S. patents is now available in the U.S. Patents Original Publications (USPATFULL) and U.S. Patents Latest Publications (USPAT2) databases.
Displaying the Assignment/Reassignment Information (RAI) format, when available, provides information about patent assignment and reassignment events, including:
- MFN - Microfilm Frame Number of document at the U.S. Patent and Trademark Office (USPTO)
- MRN - Microfilm Reel Number of document at the USPTO
- PAO - Patent Assignee, Original
- RAA - Assignment/Reassignment Agent
- RAC - Assignment/Reassignment Company
- RAD - Assignment/Reassignment Date
- RAK - Assignment/Reassignment Kind
- RAUP - Assignment/Reassignment Update Date
- RAXD - Assignment/Reassignment Execution Date
The Indented Assignment/Reassignment Information (IRAI) format is also available. It offers RAI information indented with text labels.
RAI and IRAI data is included in the MAX and IMAX display formats, respectively, and is available for custom display. Individual fields including RAI and IRAI data may also be custom displayed.
Because the source for RAI data goes back only to 1980, the U.S. Patents Pre-1976 (USPATOLD) database does not include this data.
Additional fees are charged for displaying RAI/IRAI data in USPATFULL and USPAT2. For price information, enter HELP COST at an arrow prompt (=>) in the database.
For more information about USPATFULL and USPAT2, refer to the STN Database Summary Sheet.
