Plaintiff Polaris Industries, Inc. (“Polaris”) brings this patent-infringement action
against defendants Arctic Cat Inc. and Arctic Cat Sales Inc. (collectively “Arctic Cat”).
Arctic Cat pursued an inter partes review (“IPR”) of certain claims of Polaris’s ‘501 Patent
asserting invalidity based on obviousness. The Patent Trial and Appeals Board (“PTAB”)
denied Arctic Cat’s Petition and issued a final written decision. Polaris then moved the
Court for partial summary judgment on the issue of whether Arctic Cat is estopped from
now pursuing seven combinations it identified as invalidity defenses in the instant action.
The Court will find that Arctic Cat reasonably could have raised combinations 3, 4, 6, and
7 during the IPR and will grant Polaris’s motion regarding those combinations. Because

Arctic Cat could not have reasonably raised combinations 1, 2, and 5 during IPR, the Court
will deny the motion regarding those combinations.
BACKGROUND
This case arises from the entry of Arctic Cat into the market for 4x4 Trail
Recreational Off-Road Vehicles (“4x4 Trail ROV”). Prior to 2013, Polaris had an over
90% market share in the 4x4 Trail ROV market. Polaris Indus. Inc. v. Arctic Cat Inc., No.
15-4475, 2017 WL 1180426, at *1 (D. Minn. Mar. 29, 2017). In 2013, Arctic Cat
introduced a competing product—the Wildcat Trail—which allegedly reduced Polaris’s
market share by 10%. Id. In response, Polaris filed five separate patent infringement
actions—one of which is the instant case. Id. at *1-2. Specifically, Polaris alleged
infringement of Claims 1, 10, and 11 of the ‘501 Patent in December 2015. Id. at *2.
In December 2016, Arctic Cat filed an IPR petition (“433 IPR”) with the Patent
Trial and Appeals Board (“PTAB”). (Decl. of Peter M. Kohlhepp (“Kohlhepp Decl.”) ¶
23, Ex. 22 (“IPR Pet.”) at 2, 24, Mar. 12, 2019, Docket No. 463-29.) Arctic Cat asserted
invalidity of certain ‘501 Patent claims on four grounds. (Id. at 7-8.)

Docket No. 464.)
Each of these grounds in this case and the 433 IPR are based on combinations of
various patents or printed publications, and/or physical vehicles. Sunsdahl is a printed
publication published on January 31, 2008, describing a vehicle with a continuous variable
transmission (“CVT”) intake positioned between the driver and passenger seats. (Letter,
Ex. 1 (“IPR Decision”) at 10, 11, Dec. 27, 2018, Docket No. 446-1; Davis Rep. ¶ 112.)
Suzuki is a printed publication published on November 30, 2006, describing a vehicle that
includes a CVT associated with an engine within the engine compartment and air intake
ducts connected to the CVT. (IPR Decision at 10, 29; Davis Rep. ¶ 154.) Brown is a
patent, Patent No. 4,681,178, issued July 21, 1987 describing a vehicle air intake scoop for
a vehicle’s engine where that scoop is located in a side body panel. (IPR Decision at 10,
30; Davis Rep. ¶ 156.) The Ranger Manual is a service manual for the 2007 Polaris Ranger
500. (IPR Decision at 10; Davis Rep. ¶ 147.) Chonan is a patent, Patent No. 7,427,248,
issued September 23, 2008. (IPR Decision at 10.) Nallinger is a patent, Patent No.

-3-

2,033,731, issued March 10, 1936 describing a vehicle. (IPR Decision at 10; Davis Rep. ¶
99.)
The Polaris RZR 800S, Pontiac Fiero, Polaris Ranger, and Kymco UXV 500 are all
physical vehicles. (Davis Rep. ¶¶ 127, 134, 137, 141.) Bouffard and Leonard are both
patents describing vehicles. (Davis Rep. ¶¶ 150, 152.)
None of the asserted grounds from the IPR overlap with the seven obviousness
combinations that Arctic Cat asserts in this case. (Compare IPR Pet. at 7-8 with Davis
Rep. at 39, 121, 184, 268-69, 306-07.) In December 2018 the PTAB issued a final written
decision denying Arctic Cat’s petition stating that Arctic Cat “has not shown by a
preponderance of the evidence that any of the challenged claims are unpatentable.” (Letter,
Ex. 1 at 3, Dec. 27, 2018, Docket No. 446-1.) Polaris then brought the present motion for
an order finding that Arctic Cat is estopped from asserting its identified invalidity grounds.
(Mot., Mar. 12, 2019, Docket No. 459.)
DISCUSSION
I.

STANDARD OF REVIEW
Summary judgment is appropriate when there are no genuine issues of material fact

and the moving party can demonstrate that it is entitled to judgment as a matter of law.
Fed. R. Civ. P. 56(a). A fact is material if it might affect the outcome of the suit, and a
dispute is genuine if the evidence is such that it could lead a reasonable jury to return a
verdict for either party. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248 (1986). A
court considering a motion for summary judgment must view the facts in the light most

-4-

favorable to the non-moving party and give that party the benefit of all reasonable
inferences to be drawn from those facts. Matsushita Elec. Indus. Co. v. Zenith Radio Corp.,
475 U.S. 574, 587 (1986).
II.

ESTOPPEL
Polaris argues that 35 U.S.C. § 315(e)(2) estops all of Arctic Cat’s invalidity

combinations post-IPR because Arctic Cat could reasonably have raised all of them during
IPR. Statutory estoppel under 35 U.S.C. § 315(e)(2) states:
The petitioner in an inter partes review of a claim in a patent
under this chapter that results in a final written decision . . .
may not assert . . . in a civil action arising in whole or in part
under section 1338 of title 28 . . . that the claim is invalid on
any ground that the petitioner raised or reasonably could have
raised during that inter partes review.
35 U.S.C. § 315(e)(2). IPR is limited to invalidity grounds “that could be raised under
section 102 or 103 and only on the basis of prior art consisting of patents or printed
publications.” 35 U.S.C. § 311(b). Estoppel under § 315(e)(2) thus requires: (1) a final
written decision; (2) the challenged grounds fall under §§ 102 or 103; and (3) the
challenged grounds were raised, or reasonably could have been raised during the IPR.
Only the third element is in dispute here. The PTAB issued a final written decision
in December 2018. Neither party disputes, and the Court finds that Arctic Cat’s seven
invalidity grounds—that certain claims of the ‘501 Patent are obvious—falls squarely
within § 103. See 35 U.S.C. § 103 (“A patent for a claimed invention may not be
obtained . . . if the differences between the claimed invention and the prior art are such that
the claimed invention as a whole would have been obvious . . . .”).

None of the seven invalidity grounds Arctic Cat raises in this case overlap with the
four grounds raised during the 433 IPR. Thus, the Court must decide whether Arctic Cat
reasonably could have raised the seven invalidity grounds identified in this case during the
433 IPR.
Combinations 3, 4, 6, and 7 could reasonably have been raised during the 433 IPR
so Arctic Cat is now estopped from raising them in this case. Grounds Arctic Cat
“reasonably could have raised” include “non-petitioned grounds that the defendant chose
not to present in the IPR petition,” iLife Techs. Inc. v. Nintendo of Am., Inc., No. 3:13-cv4947-M, 2017 U.S. Dist. LEXIS 87769, at *16 (N.D. Tex. May 30, 2017), but where “a
skilled searcher conducting a diligent search reasonably could have been expected to
discover,” Id. at *19 (quoting 157 Cong. Rec. S1375 (daily ed. Mar. 8, 2011) (statement of
Sen. Kyl)). Here, Arctic Cat identified these four invalidity grounds at least by March
2018, well before filing the 433 IPR. (See Davis Rep. at 310.) Thus, it is clear that Arctic
Cat did conduct a search and discovered the invalidity grounds so it reasonably could have
raised combinations 3, 4, 6, and 7 in the 433 IPR. The Court will grant Polaris’s motion
as to combinations 3, 4, 6, and 7.
Combinations 1, 2, and 5 could not reasonably have been raised during the 433 IPR
so Arctic Cat is not estopped from raising them in this case. Polaris argues that estoppel
should apply to combinations 1, 2, and 5 because Arctic Cat reasonably could have raised
those grounds during the 433 IPR using the manuals of the physical vehicles instead of the
vehicles themselves.

Polaris asserts that the manuals disclose all relevant material

information regarding the physical vehicles. Polaris further argues that allowing Arctic
-6-

Cat to point to physical vehicles rather than the printed materials describing them would
allow Arctic Cat to end-run estoppel.
Polaris has not produced, nor could this court find, any court granting the relief
Polaris now requests—to apply § 315(e)(2) estoppel to products. Although some courts
have suggested that this relief may be possible, see Oil-Dri Corp. of Am. v. Nestlé Purina
Petcare Co., Case No. 15-c-1067, 2019 U.S. Dist. LEXIS 28279, at *31 (N.D. Ill. Feb. 22,
2019) (“Where there is evidence that a petitioner had reasonable access to printed
publications corresponding to or describing a product that it could have proffered during
the IPR process, it cannot avoid estoppel simply by pointing to its finished product (rather
than the printed materials) during litigation.” (citations omitted)), such a rule has not been
recognized by any circuits. Thus, the Court declines to adopt such a rule here. Other
courts, and this Court agrees, have held that products embodying patents or printed
publications are not subject to § 315(e)(2) estoppel. 1 Only patents or printed publications
can serve as grounds for invalidity in an IPR. 35 U.S.C. § 311(b). Thus, Arctic Cat could
not reasonably have raised combinations 1, 2, and 5 during the 433 IPR because they
include physical vehicles.

The Court will deny Polaris’s motion with respect to

combinations 1, 2, and 5.

*12-13 (N.D. Tex. Apr. 4, 2018) (“Plaintiff responds that the ‘accused infringer cannot avoid
statutory estoppel simply by relying on a system where all of the teachings of the system also exist
in patents or printed publications because that ground reasonably could have been raised during
the IPR.’ This argument has been rejected in at least two prior cases, including one from this
Court. Defendants can rely on the prior art systems in their invalidity contentions to argue
anticipation or obviousness.” (internal citations omitted)); iLife, 2017 U.S. Dist. LEXIS 87769 at
