Requirement for Complete Patent and Benefit Files
Note:
Complete patent and benefit files are necessary to determine pre-AIA 102(g)(1) benefit, including IFW and paper records.

Although the official records for most applications have been converted into Image File Wrapper (IFW) files, some records exist only in paper form, particularly older benefit application files. Even IFW files may have artifact records that have not been converted. Complete patent and benefit files are necessary for determining whether benefit should be accorded for purposes of pre-AIA 35 U.S.C. 102(g)(1). A suggested interference must not be referred to the Board if all files, including benefit files, are not available to the examiner in either IFW format or paper.

Reassign Application to Same TC During Interference
Note:
If two applications in different Technology Centers are interfering, one must be reassigned to the appropriate TC where their common invention would be classified.

If the interference would be between two applications, and the applications are assigned to different Technology Centers (TCs), then one application must be reassigned. Ordinarily the applications should both be assigned to the TC where the commonly claimed invention would be classified. After termination of the interference, further transfer may be appropriate depending on the outcome of the interference.

PCT Application Included in National Stage for Benefit
Note:
A separate PCT application file is not required for benefit if it is included in a national stage application that is either the interference or benefit file.

Generally, a separate application file for a Patent Cooperation Treaty (PCT) application is not required for according benefit because the PCT application is included in a national stage application file that is itself either the application involved in the interference or a benefit file. Occasionally, however, the PCT application file itself is required for benefit. For instance, if benefit is claimed to the PCT application, but not to a national stage application in which it is included, then the PCT application file must be obtained.
