 303 Assignment Documents Not Endorsed on Pending
 Applications [R-01.2024]
 

 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 Patent Data Portal. See MPEP § 320 .
