## Text

Applications subject to AIA
35 U.S.C.
102
(see
MPEP § 2159
) may also be subject to an
interference.
Even if AIA
35 U.S.C. 102
and
103
apply
to a patent application,
pre-AIA 35 U.S.C. 102(g)
also
applies to every claim in the application if it: (1) contains or contained at any time a
claimed invention having an effective filing date as defined in
35 U.S.C.
100(i)
that occurs before March 16, 2013; or (2) is ever
designated as a continuation, divisional, or continuation-in-part of an application that
contains or contained at any time such a claim.
Pre-AIA 35 U.S.C. 102(g)
also
applies to any patent resulting from an application to which
pre-AIA 35 U.S.C.
102(g)
applied. See
MPEP §§ 2138
and
2159.03
.
Thus, if an application contains, or contained at any
time, a claim having an effective filing date that occurs before March 16, 2013, and
also contains, or contained at any time, a claim having an effective filing date that is
on or after March 16, 2013, each claim may still be subject to an interference in
accordance with
pre-AIA 35 U.S.C. 102(g)
while the application is also subject to
AIA
35 U.S.C.
102
and
103
. Pub. L. 112-29, § 3(n)(2), 125
Stat. at 293.
Where an application not subject to
pre-AIA 35 U.S.C.
102(g)
interferes with a patent subject to
pre-AIA 35 U.S.C.
102(g)
, the examiner should consult with an Interference Practice
Specialist.
