303 Assignment Documents Not Endorsed on Pending Applications
Certified copies of patent applications as filed do not include an indication of assignment documents. Applicants desiring an indication of assignment documents of record should request separately certified copies of assignment documents and submit the fees required by 37 CFR 1.19.
When the assignment condition of an application is significant, such as when applications of different inventors contain conflicting claims or there is a question as to who should direct prosecution, it is necessary for the examiner to obtain assignment information from PALM. See MPEP § 320.
