DECISION ON APPEAL
STATEMENT OF THE CASE
Pursuant to 35 U.S.C. § 134(a), the Appellant1 appeals from the
Examiner’s decision to reject claims 34–37. We have jurisdiction under
35 U.S.C. § 6(b).
We REVERSE.

1 We use the word Appellant to refer to “applicant” as defined in
37 C.F.R. § 1.42(a). The Appellant identifies the real party in interest as
Carl Zeiss SMT GmbH (Appeal Br. 1).

CLAIMED SUBJECT MATTER
The claims are directed to METHOD FOR MASS
SPECTROMETRIC EXAMINATION OF GAS MIXTURES AND MASS
SPECTROMETER THEREFOR. Claim 34, reproduced below, is
illustrative of the claimed subject matter.
34. A mass spectrometer, comprising:
an ionizer configured to provide charged particles or a
plasma;
a gas reservoir configured to store an ionization gas;
a gas feed configured to deliver the ionization gas from
the gas reservoir to the ionizer; and
a three dimensional ion trap configured to store ions,
wherein the mass spectrometer is configured so that
during use of the mass spectrometer:
external to the three dimensional ion trap, the ionization
gas is delivered from the gas reservoir to the ionizer so that the
ionization gas interacts with charged particles or is exposed to
the plasma provided by the ionizer to produce a product
comprising at least one member selected from the group
consisting of ions of the ionization gas and metastable particles
of the ionization gas;
the product is transferred from the ionizer to the three
dimensional ion trap;
in the three dimensional ion trap, the product ionizes a
gas mixture to provide an ionized gas mixture; and
the three dimensional ion trap mass spectrometrically
examines the ionized gas mixture.

REJECTION
Claims 34–37 stand rejected under 35 U.S.C. § 102(b) over Baba.
OPINION
We need address only claim 34, which is the sole rejected independent
claim. That claim requires a mass spectrometer having a three dimensional
ion trap wherein an ionizer product can ionize a gas mixture to provide an
ionized gas mixture.
“Anticipation requires that every limitation of the claim in issue be
disclosed, either expressly or under principles of inherency, in a single prior
art reference.” Corning Glass Works v. Sumitomo Elec. U.S.A., Inc., 868
F.2d 1251, 1255–56 (Fed. Cir. 1989).
Baba discloses a mass spectrometer having an ionizer (Fig. 6,
items 107–123; Para. 76), a three dimensional ion trap (Fig. 6, items 125–
127; Para. 82), and an ion detector (Fig. 6, item 129; Para. 82). In the
ionizer, molecules (G) of reagent gas (which corresponds to the Appellant’s
ionization gas 30; Fig. 4) capture an electron emitted from a tungsten
filament (107) to form primary ions (G-) which chemically ionize
molecules (M) of sample gas (which corresponds to the Appellant’s gas
mixture 2; Fig. 4) to form sample ions (M-) which are captured inside the
three dimensional ion trap and are discharged from that trap to the ion
detector (Paras. 81, 82).
The Examiner finds that “in [Baba’s] three dimensional ion trap, the
product ions of the ionization gas ionizes a gas mixture to provide an ionized
gas mixture” (Ans. 7).
That finding is incorrect. Baba’s reagent gas (G) product ions ionize
the sample gas (M) in the ionizer, not in the three dimensional ion trap

(Para. 81). The Examiner has not established that Baba’s mass spectrometer
is capable of sample gas molecule (M) ionization by reagent gas ions (G-) in
the three dimensional ion trap. The Examiner, therefore, has not shown that
Baba discloses, expressly or inherently, every limitation in the Appellant’s
sole independent claim on appeal. Accordingly, we reverse the rejection.
CONCLUSION
The Examiner’s rejection is reversed.
