How does the USPTO treat disclosures with additional authors or inventors?
The USPTO’s treatment of disclosures with additional authors or inventors depends on how they relate to the named inventors in the patent application. According to MPEP 2153.01(a):
1. When the application names more inventors than the disclosure:
“This means that in circumstances where an application names additional persons as joint inventors relative to the persons named as authors in the publication (e.g., the application names as joint inventors A, B, and C, and the publication names as authors A and B), and the publication is one year or less before the effective filing date, it is apparent that the disclosure is a grace period inventor disclosure, and the publication is not prior art under AIA 35 U.S.C. 102(a)(1).”
2. When the disclosure names more authors than the application:
“If, however, the application names fewer joint inventors than a publication (e.g., the application names as joint inventors A and B, and the publication names as authors A, B and C), it would not be readily apparent from the publication that it is an inventor-originated disclosure and the publication would be treated as prior art under AIA 35 U.S.C. 102(a)(1) unless there is evidence of record that an exception under AIA 35 U.S.C. 102(b)(1) applies.”
In cases where the disclosure names additional authors, applicants may need to provide evidence, such as an affidavit or declaration under 37 CFR 1.130(a), to establish that the disclosure qualifies for the grace period inventor-originated disclosure exception.
