14. On August 7, 1997, practitioner Costello filed a patent application identifying Laurel,
Abbot, and Hardy as inventors. Each named inventor assigned his patent rights to Burns just
prior to the application being filed. Laurel and Abbot, alone, jointly invented the subject matter
of independent claim 1 in the application. Hardy contributed to inventing the subject matter of
claim 2. Claim 2 properly depends upon claim 1. The examiner rejected claim 1 and claim 2
under 35 U.S.C. § 102(a) as anticipated by a journal article by Allen, dated July 9, 1997. Laurel,
Abbot, and Hardy are readily available to provide evidence in support of and sign an antedating
affidavit under 37 C.F.R. § 1.131 showing reduction to practice of the subject matter of claims 1
and 2 prior to July 9, 1997. Which of the following may properly make an affidavit under 37
C.F.R. § 1.131 to overcome the rejection of claims 1 and 2.?
(A) Laurel and Abbot.
(B) Laurel, Abbot, and Hardy.
(C) Laurel, Hardy and Burns.
(D) Burns only.
(E) None of the above.
14. ANSWER: (B). MPEP 715.04. (A) is incorrect since it cannot be shown that less than all
the inventors invented the subject matter of claim 2. (C) and (D) are incorrect since the assignee
can make an affidavit under 37 C.F.R. § 1.131, only when it is not possible to produce the
affidavit of the inventor. The facts indicate that all inventors were readily available produce the
affidavit. (E) is incorrect since (B) is correct.
