Request to Prevent Inventor Access Must Be Filed Separately
Note:
Inventors can be prevented from accessing application files only if a separate request is filed with the Office of Petitions and granted.

The applicant or assignee of record of the entire interest in an application may file an application or intervene in the prosecution of the application, appointing an attorney or agent of his or her own choice. See 37 CFR 1.46 and 3.71. Such an application filing or intervention, however, does not exclude the inventor from access to the application to see that it is being prosecuted properly, unless the applicant or assignee makes specific request to that effect. Any request to prevent the inventor from obtaining access to the file should be filed as a separate paper, 37 CFR 1.4(c), and should be directed to the Office of Petitions. If the request is granted, the inventor will be informed that he or she will only be permitted to inspect the application on sufficient showing why such inspection is necessary to conserve his or her rights. Of course, after the application has published pursuant to 35 U.S.C. 122(b), the application will be available to the public and any restriction on the inventor to access his or her application previously granted will no longer be in effect.
