PTA for Interference Time
Note:
An applicant may receive a day-for-day patent term adjustment for time spent in an interference.

An applicant may be entitled to a day-for-day patent term adjustment for any time spent in an interference. If an applicant has several related applications with interfering claims intermixed with claims that do not interfere, the examiner should consider whether the interfering claims should be consolidated in a single application or whether an application should be restricted to claims that do not interfere. This way examination can proceed for any claims that do not interfere without the delay that will result from the interference.
