2304 Suggesting an Interference

An interference may be suggested by an applicant or an examiner. This section explains what happens depending on whether an applicant or an examiner calls the interference. It discusses the preliminary activities that need to happen before referring an interference to the Board. For instance, an interference search must be performed on each application in condition for allowance.

In addition, this section covers the difference between the proceedings when an applicant suggests an interference vs. when the examiner suggests an interference. For example, when an applicant suggests an interference, the examiner will need to review the suggestion to ensure it meets the requirements. A patentee may not suggest an interference. The only way is for the patentee to become an applicant by filing a reissue application. Further details for suggesting an interference are covered in this section.
