What is the significance of application and patent dates in interference searches?
Application and patent dates are not limiting factors in interference searches. According to MPEP 2304.01(a):
“The search should be directed to all subject matter encompassed by the claims, whether or not the claims are limited by an application or patent date.”
This means that:
- Examiners must search for potentially interfering subject matter regardless of filing dates
- Older applications or patents can still be relevant to an interference search
- The focus is on the subject matter of the claims, not the temporal aspects of the applications or patents
This approach ensures a comprehensive search that identifies all potential conflicts, regardless of when the applications were filed or patents were issued.
