How can patent examiners update the classification of foreign patents?
Patent examiners can update the classification of foreign patents by following these steps, as outlined in MPEP 903.03:
If the examiner desires to update the USPC classification of a foreign patent by changing, canceling, or adding copies, they should forward the patent (or bibliographic information) to their supervisory patent classifier with a request for the desired transaction attached.
This process allows examiners to:
- Change the existing classification
- Cancel a classification
- Add new classifications
By updating classifications, examiners help maintain an accurate and up-to-date patent classification system, which is crucial for effective prior art searches and patent examination.
