24. In 1995 Patent Agent filed a U.S. patent application containing five claims
(Application 1). All five claims are fully supported under 35 U.S.C. § 112 by the
disclosure of Application 1. In 2000, Patent Agent filed a U.S. patent application
(Application 2) that was a continuation- in-part of Application 1. Application 2 adds new
subject matter to the disclosure of Application 1, and ten additional claims. Of the fifteen
claims in Application 2, claims 1-5 are exactly the same as Application 1, claims 6-10 are
fully supported under 35 U.S.C. § 112 by the disclosure of Application 1, and claims 11-
15 are fully supported under 35 U.S.C. § 112 only by the newly added subject matter of
Application 2. The effective filing date for claims in Application 2 is:
(A) 1-15 is 2000.
(B) 1-15 is 1995.
(C) 1-10 is 1995.
(D) 11-15 is 2000.
(E) (C) and (D).
ANSWER (E) The characterizing feature of a CIP is multiple filing dates. This question again
illustrates that the PTO wants you to know this feature. C and D set forth that the
claims are split between the two applications. Easy question if you remember the
CIP axiom of multiple filing dates. (By the way it also has multiple 102(e) dates
as a reference, but we’ll save that for another day!)
