THE CLAIMED SUBJECT MATTER
Claims 1 and 4 are independent. Claim 1, reproduced below, is
illustrative of the subject matter on appeal.
1. A high frequency heating apparatus comprising a
plurality of high frequency generators disposed over a glass
substrate to be carried in a first direction and spaced apart from
each other in the first direction, each of the plurality of high
frequency generators generating high frequency to heat the
glass substrate, the high frequency ranging from 0.98 GHz to
6.0 GHz,
wherein a distance from the glass substrate to each of the
plurality of high frequency generators is (n'/2)*A, where n' is a
natural number ranging from 1 to 6, and A is a wavelength of
the high frequency.
OPINION
Claims 1, 3, 5-7, 9-14, and 16-21
In rejecting independent claim 1, the Examiner finds that Sortais
teaches, inter alia,
a plurality of high frequency generators (3,6,7,8,para[.]
3)disposed over a glass substrate (para[.] 3 -transistors/glass,
para[.] 51) ... , wherein a distance from the glass substrate to
each of the plurality of high frequency generators is
(n'/2)*(lambda)(para[.] 12-half wavelength), where n' is a
natural number ranging from 1 to 6(para[.] 12), and [lambda] is
a wavelength of the high frequency(para[s.] 3,12,28,35,40).
2 Claims 2, 8, and 15 are cancelled. See Amendment (Dec. 21, 2016).

Appeal2018-004593
Application 13/786,240
Final Act. 2-3. The Examiner acknowledges that "[t]he claims differ at best
in the recited distance to a glass substrate in half wavelengths." Id.
However, the Examiner finds that Nehls teaches that "spacing/distance is by
half wavelengths (para[s.] 75,78, 114,143,158,172,173, 174)." Id. at 6. The
Examiner also finds that "Pavliscak teaches similarly ... [that ']each ionized
area is disposed, with respect to adjacent ionized plasma areas, a distance
equivalent to approximately one half of a wavelength associated with the at
least one operating frequency band.[']" Id. (boldface omitted) (quoting
Pavliscak, col. 10, 11. 33-37). The Examiner determines that it would have
been obvious
to modify ... Sortais by spacing the distance to a substrate in
half wavelengths as taught by Nehls or Pavliscak for uniformity
of power and temperature in heating a glass substrate for cost
effectiveness, light and plasma sources. This includes 2
wavelengths as set forth in the present [S]pecification in
para[s.] 41,43.
Id.; see also Ans. 14 ("There is a motivation to improve [ the distance
between the generators and the substrate] and Nehls teaches homogeneous
heating distribution as a motivation. Nehls teaches the claimed distance as
best understood using high frequency generators and its obvious result.").
Appellant argues that the cited references do not teach or suggest "a
distance from the glass substrate to each of the plurality of high frequency
generators is (n'/2)*A, where n' is a natural number ranging from 1 to 6, and
A is a wavelength of the high frequency," as recited in claim 1. Supp.

wavelength spacing between high frequency generators and the substrate.
Id. at 7 (citing Nehls ,r,r 75, 78, 88, 114, 143, 158, 172-174). The Examiner
responds, in the Answer, that Nehls teaches that "separation of antennas for
the space 20(substrate) [is] preferably selected so that an essentially
homogeneous field strength distribution is obtained[;] this being a separation
from the space 20 which is more than at least one wavelength of the
microwave radiation." Ans. 13 (citing Nehls ,r 143). The Examiner also
finds that, "[i]n para[.] 102 [of Nehls], separation is defined [as] the distance
between the substance/substrate and the plane on which the microwave
antenna [is] arranged. Table 2 follows for the examples teaching separation
of 3,6 cm." Id. According to the Examiner, "Nehls teaches more than at
least one wavelength. That teaching is within the range of the recitation
(n/2)[lambda] in claims 1 and 4. Nehls also teaches the distance. See at
least para[.] 102 and table 2." Id. at 17.
We agree with Appellant that the Examiner has not adequately
supported a finding that Nehls teaches the distance between the substrate and
high frequency generators required by claim 1. The claim recites that this
distance "is (n'/2)*A, where n' is a natural number ranging from 1 to 6."
Appeal Br. 11 (Claims App.). Natural numbers ranging from 1 to 6 include
the numbers 1, 2, 3, 4, 5, and 6, and thus, for n' values of 1, 2, 3, 4, 5, and 6,
a distance (n'/2)*A includes 0.5A, A, 1.5A, 2A, 2.5A, and 3A. In other words,
claim 1 requires a distance between the substrate and high frequency
generators of0.5A, A, 1.5A, 2A, 2.5A, or 3A (i.e., one of six discrete values).

Appeal2018-004593
Application 13/786,240
Nehls teaches that microwave radiator 50 produces microwave
radiation to heat space 20, and microwave radiator 50 and space 20 are
separated at a distance such "that an essentially homogeneous field strength
distribution is obtained in the space 20, this being achievable in particular by
the microwave radiator unit having a separation from the space 20 which is
more than at least one wavelength of the microwave radiation." Nehls ,r 143
(emphasis added). We fail to see how Nehls' broad teaching of a separation
value of "more than at least one wavelength of the microwave radiation" (id.
( emphasis added)) would meet the disputed limitation that specifies only six
discrete values for the separation.
Nehls also teaches a test scenario with particular values for "[t]he
separation describ[ing] the distance between the substance mixture and the
plane on which the microwave antennas are arranged." Id. ,r 102. In
particular, Nehls teaches separation distances of 3cm, 6cm, and 12cm
separating the substance mixture and antennas. Id. at Table 2. In this
regard, we agree with Appellant that there is insufficient evidence to support
the Examiner's position that separation values in Table 2 of Nehls
correspond to the distance values encompassed by the formula recited in
claim 1 (i.e., 0.5A, A, 1.5A, 2A, 2.5A, or 31v). See Reply Br. 8 (Asserting that
"the Examiner is assuming that 3 cm corresponds to (n'/2)*A, where n' is a
natural number ranging from 1 to 6, and A is a wavelength of the high
frequency, but there is no support for this assumption in Nehls."). Paragraph
102 and Table 2 of Nehls do not discuss frequency or wavelength, and the
Examiner has not adequately explained how the separation values of 3 cm or
6 cm relate to any particular wavelength such that it could be determined
whether such separation values represent 0.5A, A, 1.5A, 2A, 2.5A, or 3A, as

Application 13/786,240
called for in claim 1. Thus, the Examiner's finding as to the disclosure of
Nehls lacks adequate evidentiary support.
The Examiner's reliance on Pavliscak in the rejection of claim 1 does
not remedy the aforementioned deficiency in Nehls. Pavliscak teaches that
"each ionized plasma area is disposed, with respect to adjacent ionized
plasma areas, a distance equivalent to approximately one half of a
wavelength associated with the at least one operating frequency band."
Pavliscak, col. 10, 11. 33-37. The Examiner takes the position that
"Pavliscak teaches design criteria for glass devices relating to approximately
one half wavelength associated with at least one operating band." Ans. 18.
However, as Appellant points out, "Pavliscak does not refer to a distance
between a glass substrate and a high frequency generator, [but, rather,] is
referring to [distances between] ionized plasma areas." Supp. Appeal Br. 9
(boldface and underlining omitted); Reply Br. 8.
The Examiner's conclusion of obviousness is based on an insufficient
finding as to the scope and content of Nehls and Pavliscak, namely, that
Nehls and Pavliscak each teach that the distance between the plasma source
(i.e., high-frequency generator) and the substrate is "(n'/2)*A, where n' is a
natural number ranging from 1 to 6, and A is a wavelength of the high
frequency" (i.e., 0.5A, A, 1.5A, 2A, 2.5A, or 31v), as called for in claim 1.
For the foregoing reasons, we are persuaded that the Examiner erred
in concluding that the combination of Sortais, Nehls, and Pavliscak renders
obvious the subject matter of independent claim 1. Accordingly, we do not
sustain the rejection of independent claim 1 and its dependent claims 3, 5-7,
9-14, and 16-21 under 35 U.S.C. § 103(a) as unpatentable over Sortais,
Nehls, and Pavliscak.

Claim 4
Independent claim 4 recites, in relevant part, that "the plurality of high
frequency generators are arranged at distances expressed by (n' '/2)*A, where
n'' is a natural number ranging from 1 to 12, and A, is a wavelength of the
high frequency." Appeal Br. 11 (Claims App.). 4 To the extent that the term
"distances" as recited in claim 4 means the distances between the generators
and a substrate, the Examiner's rejection of claim 4 relies on the same
deficient findings and reasoning discussed above in connection with claim 1.
See Final Act. 7 ("See the rejection of claim 1."); Ans. 19 (Stating that, "the
PTO repeats and incorporates its above Response to Arguments here for
independent claim 1. ").
To the extent that the term "distances" as recited in claim 4 means the
distances between the generators, we agree with Appellant that Sortais
discloses distances "between the coupler and the central rod of 5 to 15 times
smaller than the quarter of the wavelength, not half of the wavelength."
Reply Br. 5 ( emphasis omitted). We also agree with Appellant that the
Examiner has not adequately explained how Nehls or Pavliscak teaches the
claimed distances between generators. Id. at 5-8.
We note that Pavliscak teaches that "each ionized plasma area is
disposed, with respect to adjacent ionized plasma areas, a distance
equivalent to approximately one half of a wavelength associated with the at
4 The Examiner indicates that it is "unclear as to how [those] distance[s]
[are] measured relative to generators with or without reflectors having
various characteristics alone or in arrays." Ans. 14. For purposes of this
opinion, we adopt a broad interpretation of "distances" as recited in claim 4
as being any distance between the generators or any distance between the
generators and the substrate.

least one operating frequency band." Pavliscak, col. 10, 11. 33-37.
However, the Examiner has not adequately explained how or why this
teaching regarding distance between adjacent plasma areas would have
prompted one of ordinary skill in the art to modify Sortais so as to arrange
central rod 3 and coupler rods 6, 7, 8 (i.e., the Examiner's plurality of high
frequency generators (Final Act. 2)) at distances of (n' '/2)*A, where n'' is a
natural number ranging from 1 to 12, as called for in claim 4. For example,
Sortais discloses a plasma source having plasma area 14 extending beyond
the ends of rods 3, 6, 7, 8. Sortais ,r 45, Fig. 4. Although Sortais also
discloses an assembly of such plasma sources (id. f 49, Figs. 6A-6B), there
is no indication that the distances between plasma areas in an assembly of
plasma sources would also be indicative of the specific distances between
the rods or generators.
Thus, we also do not sustain the rejection of claim 4 under 35 U.S.C.
§ 103(a) as unpatentable over Sortais, Nehls, and Pavliscak.
DECISION
The Examiner's decision to reject claims 1, 3-7, 9-14, and 16-21
under 35 U.S.C. § 103(a) as unpatentable over Sortais, Nehls, and Pavliscak
is REVERSED.
