Before DYK, CLEVENGER, and TARANTO, Circuit Judges.
PER CURIAM.
U.S. Patent No. 9,604,008 (the ’008 patent), owned by
Sanofi-Aventis Deutschland GmbH (Sanofi), is directed to
a “drive mechanism for use in a drug delivery device.” ’008
patent, col. 17, l. 28. In this inter partes review, the Patent
Trial and Appeal Board (Board) held that claims 1, 7, 8,
and 17 of the ’008 patent were unpatentable as obvious
over a combination of two prior art references—Møller
(U.S. Patent Pub. No. 2002/0052578) and Steenfeldt-Jen-
sen (U.S. Patent No. 6,235,004). Sanofi appeals. We af-
firm.
On appeal, Sanofi argues that the Board committed
two errors. First, it argues that the Board erred in finding
that there was a motivation to combine the two references.
The Board found that Steenfeldt-Jensen provided benefits
supporting the combination of Møller’s dose-setting ap-
proach with Steenfeldt-Jensen’s dose-dispensing approach,

SANOFI-AVENTIS DEUTSCHLAND v. 3
MYLAN PHARMACEUTICALS, INC.
that Mylan’s expert testimony supported the benefits of the
combination, and that Møller contemplated the combina-
tion. Sanofi argues that Møller disparages the Steenfeldt-
Jensen dose-setting approach by specific reference to
Steenfeldt-Jensen. Møller states, in reference to embodi-
ments disclosed in a related Patent Cooperation Treaty
(PCT) filing for Steenfeldt-Jensen (WO 99/38554):
A similar gearing is provided in WO 99/38554
wherein the thread with the high pitch is cut in the
outer surface of a dose setting drum and is engaged
by a mating thread on the inner side of the cylin-
drical housing. However, by this kind of gearing
relative large surfaces are sliding over each other
so that most of the transformed force is lost due to
friction between the sliding surfaces. Therefore a
traditional gearing using mutual engaging gear
wheels and racks is preferred.
Møller, ¶ [0008]. Even though the specific feature of Steen-
feldt-Jensen referenced in Møller (large surfaces of the
dose-setting drum threaded with the housing) is not part of
the injection mechanism for the proposed combination, the
Steenfeldt-Jensen approach involves some friction which
Møller describes as undesirable. But substantial evidence
supports the Board’s finding that one skilled in the art
would not be deterred by the possibility of some additional
friction to make the combination since use of the Steen-
feldt-Jensen approach, rather than the Møller approach,
would reduce the number of parts while limiting overall
force required. The Board did not err in finding a motiva-
tion to combine.
Second, Sanofi argues that the Board erred by finding
the same prior art element was both the claimed “housing”
and the “insert provided in the housing.” ’008 patent,
col. 17, ll. 27–34. Sanofi explains in its opening brief, “an
element may be a housing, or it may be an insert, but it
cannot concurrently be both a housing and an insert ‘in’

MYLAN PHARMACEUTICALS, INC.
that housing.” Appellant’s Br. 43. The claim language does
not preclude an insert being part of the housing. The spec-
ification also supports the Board’s construction that claim
1 does not require “an insert that is separate from the hous-
ing.” Mylan Pharms. Inc. v. Sanofi-Aventis Deutschland
GmbH, IPR2018-01684, at 31 (P.T.A.B. May 29, 2020).
The specification of the ’008 patent explains that the
“‘housing’ . . . shall preferably mean any exterior housing
. . . or interior housing (‘insert’, ‘inner body’),” col. 2, l. 66–
col. 3, l. 1, “the housing may be unitary or a multipart com-
ponent,” col. 3, ll. 9–10, and “the insert may be formed in-
tegrally with the main housing,” col. 7, ll. 37–38. These
passages provide substantial support for the Board’s con-
struction. The Board did not err in its claim construction.
AFFIRMED
