human: An application is filed with only one line of specification, which is a priority claim to a foreign application, and one broad claim. Can applicant subsequently add material from the foreign application and draft claims based on such added material?
assistant: Yes, if the requirements of 37 CFR 1.57(a) are met. Although 37 CFR 1.57(a) provides for the later addition of material from a prior foreign application, the initial absence of the material from the U.S. application must result from inadvertence. The presentation of an amendment to add the subject matter from the foreign application is a certification pursuant to 37 CFR 10.18(b) that the initial omission of such material was due to inadvertence. The Office may inquire as to inadvertence where the record raises an issue in regard thereto. See 69 Fed. Reg. 56481, 56503 at Comment 44 and the Response thereto in the published final rule.
