MEMORANDUM OPINION AND ORDER
Plaintiff Knowles Electronics and the related defendant entities, American
Audio Components and AAC Technologies Holdings (for convenience, they will be
referred to together as “AAC”), disagree as to the proper interpretation of a
settlement agreement.1 Years ago, Knowles and AAC settled a number of pending
and threatened intellectual-property claims, all stemming from AAC’s manufacture
of what Knowles characterizes as a knock-off Knowles microphone. See R. 169,
Second Am. Compl.; R. 254, Knowles Compl. at Exh. B, Settlement Agreement.2 As
part of the Settlement Agreement, the parties cross-licensed their respective
patents and AAC agreed to pay royalties to Knowles on certain products
incorporating Knowles’ intellectual property. Settlement Agreement § 2.

1This

Court has subject matter jurisdiction under 28 U.S.C. § 1332. See also R. 253,
6/7/16 Order; R. 295, 3/8/17 Op. at 2 n.2.
2Citations to the docket are indicated by “R.” followed by the docket number and,
where applicable, a page or paragraph number.

The parties abided by the Settlement Agreement for several years without
incident. In 2016, however, Knowles brought this enforcement action against AAC,
claiming that AAC was withholding royalties in violation of the Settlement
Agreement. See Knowles Compl. ¶¶ 90-91. AAC responded with various
counterclaims, requesting judicial interpretation of the Agreement, as well as a
declaratory judgment of noninfringement on two Knowles patents and no royalties
owed on a number of specific products. See R. 260, Defs.’ Countercl. The resolution
of the enforcement dispute rested entirely on contractual interpretation of the
Settlement Agreement, so the parties brought cross-motions for judgment on the
pleadings, R. 278, Pl.’s Mot. for J. on the Pleadings; R. 284, Defs.’ Mot. for J. on the
Pleadings, and the Court read the Agreement to unambiguously require the
continued payment of royalties, R. 295, 3/8/17 Op. AAC now moves for
reconsideration of that decision. R. 301, Defs.’ Mot. for Reconsideration. For the
reasons stated below, the motion to reconsider is denied.
I. Background
As in the Opinion deciding the cross-motions for judgment on the pleadings,
the Court takes all well-pled allegations as true and draws all reasonable inferences
in the nonmovant’s favor. Hayes v. City of Chi., 670 F.3d 810, 813 (7th Cir. 2012).
But here, the material facts are not in dispute. Instead, the parties’ motions turn
entirely on the interpretation of the words in the contract.
The facts of the original intellectual-property litigation and the current
enforcement dispute are laid out in detail in the prior Opinion, R. 295, so there is no
2

need to repeat all of that here. Only the most pertinent details—that is, the
disputed language in the Settlement Agreement—are included in this Opinion.
The Agreement resolved a number of legal actions that Knowles and AAC
were pursuing against one another in 2006 and 2007. Settlement Agreement at
Preamble. These included a lawsuit filed in this district, a threated patentinfringement complaint to the United States International Trade Commission, and
two patent-related proceedings in China. Id. at Preamble, § 3; Knowles Compl. ¶ 75;
R. 260, Defs.’ Ans. ¶ 75. As partial consideration for the dismissal of existing claims
and the release of future claims, the Settlement Agreement granted AAC a royaltybearing license to use the “Knowles Patents,” defined as:
United States Patent No. 6,781,231 B2 (the “’231 Patent”), United States
Patent No. 7,242,089 B2 (the “’089 Patent”) United States Patent No.
7,166,910 (the “’910 Patent”), and any patents that share an application in
common with these patents or claims the benefit of the same filing date as
these patents, including all continuations, divisions, reissues, reexaminations and world-wide corresponding patents.
Settlement Agreement § 1.4; see also id. § 2.1. Royalties would be computed in
accordance with a two-tier payment structure, with the applicable rate dependent
on whether a product was a “First Tier Royalty Product” or a “Second Tier Royalty
Product” and on the amount of AAC’s aggregate net sales to date on the royalty
products. Id. §§ 1.5, 2.3-2.6.
The core of the enforcement dispute rests on the definitions of “First Tier
Royalty Products” and “Second Tier Royalty Products.” First Tier Royalty Products
incorporate the ’231 Patent:
3

First Tier Royalty Products shall mean AAC microphones … within the scope
of, or covered by, the language of any claim of the ’231 Patent including,
without limitation, Part Numbers: SM0102, SM0301, SM0301L, SM0301EL,
SM0401L, SM0401EL, SDM0102, SDM0301, SDM0401 and SDM0501.
Settlement Agreement § 1.5(A). Second Tier Royalty Products incorporate the ’089
and ’910 Patents:
Second Tier Royalty Products shall mean AAC microphones … within the
scope of, or covered by, the language of any claim of the ’089 or ’910 Patents
including, without limitation, Part Numbers SM0102B, SM0102BL,
SM0301BL, SM0301BEL, SM0401BL, SM0401BEL, SDM0102B, SDM0301B,
SDM0401B, and SMD0501B.
Id. § 1.5(B). The definition went on to clarify that products acknowledged as
incorporating both the ’231 and ’089 or ’910 Patents were to be considered First Tier
Royalty Products and were explicitly excluded from the Second Tier Royalty
Products category. Id.
Had the scope of the Knowles Patents remained static, there would have been
no issue. But in March 2014, the Patent and Trademark Office reexamined the ’089
Patent and cancelled all but one of the then-existing claims (Claim 5), although it
later added additional claims (Claims 30-61). R. 260-4, Defs.’ Ans. and Countercl. at
Exh. E, 3/5/14 Inter Partes Reexam. Cert.; R. 260-4, Defs.’ Ans. at Exh. F, 4/2/14 Ex
Parte Reexam. Cert. AAC took this to mean that it no longer had to pay royalties on
the products covered by the cancelled claims, Knowles Compl. ¶ 93; Defs.’
Countercl. ¶¶ 22-23, and stopped paying royalties on Part Numbers SM0102B,
SM0401BL, and SDM0401B. According to AAC, these three Part Numbers were
solely covered by the cancelled ’089 Patent claims, Defs.’ Countercl. ¶ 24, but
4

Knowles denies this, R. 272, Pl.’s Ans. to Countercl. ¶ 24, so there is some dispute
over whether the disputed Part Numbers fall inside the scope of the reexamined
’089 Patent. Nonetheless, Knowles maintains that the Settlement Agreement
expressly requires royalties on those specific Part Numbers, irrespective of any
reexaminations or claim cancellations. See Knowles Compl.
Knowles sued for breach of contract, Knowles Compl., and AAC countersued
for a declaratory judgment confirming its obligation to pay royalties only on those
products within the scope of current claims of the ’089 Patent and ’231 Patent (the
latter of which was reexamined in 2015, and—as far as the record shows—remains
pending on appeal before the Federal Circuit), Defs.’ Countercl. The parties filed
cross-claims for judgment on the pleadings, each arguing that the Settlement
Agreement unambiguously supported its own interpretation. Pl.’s Mot. for J. on the
Pleadings; Defs.’ Mot. for J. on the Pleadings. The Court held that (1) the
Agreement was unambiguous, and could therefore be construed without looking at
extrinsic evidence; and (2) based on the language of the Agreement, the cancellation
of certain claims of the Knowles Patents did not affect AAC’s obligation to “pay
royalties on, at the very least, the specified Part Numbers [SM0102B, SM0401BL,
and SDM0401B].” 3/8/17 Op. at 11. Therefore, AAC had improperly withheld
royalties and needed to pay. AAC now moves the Court to reconsider its decision
pursuant to Federal Rule of Civil Procedure 54(b).

II. Legal Standard
Federal Rule of Civil Procedure 54(b) states that a court may reconsider an
interlocutory ruling “at any time before the entry of a judgment adjudicating all the
claims and all the parties’ rights and liabilities.” Fed R. Civ. P. 54(b). Motions for
reconsideration serve the narrow purpose of correcting manifest errors of law or fact
or presenting newly discovered evidence. Rothwell Cotton Co. v. Rosenthal & Co.,
827 F.2d 246, 251 (7th Cir. 1987). Thus, a motion to reconsider is proper when “the
Court has patently misunderstood a party, or has made a decision outside the
adversarial issues presented to the Court by the parties, or has made an error not of
reasoning but of apprehension.” Bank of Waunakee v. Rochester Cheese Sales, Inc.,
906 F.2d 1185, 1191 (7th Cir. 1990) (citation omitted). But a motion for
reconsideration “does not provide a vehicle for a party to undo its own procedural
failures, and it certainly does not allow a party to introduce new evidence or
advance arguments that could and should have been presented to the district court
prior to the judgment.” Bordelon v. Chi. Sch. Reform Bd. of Trs., 233 F.3d 524, 529
(7th Cir. 2000) (internal quotation marks and citation omitted); see also Caisse
Nationale de Credit Agricole v. CBI Indus., Inc., 90 F.3d 1264, 1270 (7th Cir. 1996)
(“[R]econsideration is not for rehashing previously rejected arguments.”).
III. Analysis
AAC argues first that the prior Opinion did not draw reasonable inferences in
favor of AAC, as required under the Rule 12(c) standard, when considering Knowles’
motion for judgment on the pleadings. AAC also contends that the prior Opinion
6

failed to consider AAC’s arguments as to the patent-misuse doctrine when
interpreting the Settlement Agreement. There is some overlap between these two
arguments, because they both go towards AAC’s contention that its reading of the
Agreement is at least a—if not the only—reasonable interpretation. But because the
arguments involve very different legal analyses, the Court will address them
separately and in turn.
A. Failure to Draw Reasonable Inferences in AAC’s Favor
First, AAC argues that the prior Opinion incorrectly applied the legal
standard for a Rule 12(c) motion, which requires “all reasonable inferences” to be
drawn “in favor of the nonmovant.”3 See Wagner v. Teva Pharm. USA, Inc., 840 F.3d
355, 358 (7th Cir. 2016); Defs.’ Br. at 5-9. The Opinion did set forth that standard of
review, R. 295 at 8-9, so what AAC really contends is that the Opinion did not
“address the arguments that AAC’s construction [of the Agreement] is” plausible, so
reconsideration is appropriate. R. 320, Defs.’ Reply Br. at 4 (emphasis omitted); see
also Rothwell Cotton, 827 F.2d at 251 (quoting Keene Corp. v. Int’l Fidelity Ins. Co.,
561 F. Supp. 656, 664-55 (N.D. Ill. 1983), aff’d, 736 F.2d 388 (7th Cir. 1984)).
Before tackling the substance of this argument, the Court makes one
preliminary note: previous drafts of the Agreement cannot factor into the analysis of
whether the contract is ambiguous, nor can they provide the grounds for arguing
that the apparent meaning of a facially unambiguous contract is unreasonable.
3Where,

as here, the parties have filed cross-motions for judgment on the pleadings,
the Court adopts a “‘dual perspective[,]’ [] resulting sometimes in the denial of both
motions.” Bechtold v. Physicians Health Plan of N. Ind., Inc., 1993 WL 625573, at *3 n.3
(N.D. Ind. Mar. 19, 1993), aff’d, 19 F.3d 322 (7th Cir. 1994) (citation omitted).

7

Indeed, the Agreement contains an explicit integration clause, Settlement
Agreement § 9.6, so AAC may not use outside evidence to establish an “extrinsic
ambiguity.” See Air Safety, Inc. v. Teachers Realty Corp., 706 N.E.2d 882, 885 (Ill.
1999). Instead, the Agreement is ambiguous only if—based solely on the language of
the contract—it is “susceptible to more than one meaning.”4 Id. at 884.
AAC contends that—with all reasonable inferences properly drawn in its
favor—its interpretation of the Agreement would have prevailed or, at the very
least, been found just as reasonable as the one offered by Knowles. Defs.’ Br. at 5-9.
But this argument misapprehends the Rule 12(c) standard. The Court must take
“reasonable factual inferences in favor of the” nonmovant, Vose v. Kliment, 506 F.3d
565, 569 (7th Cir. 2007) (emphasis added), but the Court “is not bound by the nonmoving party’s legal characterizations of the facts,” Legion Ins. Co. v. Vemuri, 1997
WL 757529, at *2 (N.D. Ill. Nov. 24, 1997) (emphasis added) (citing Republic Steel
Corp. v. Penn. Eng’g Corp., 785 F.2d 174, 177 n.2 (7th Cir. 1986)). Here, the parties
do not dispute the operative terms of the Agreement. The only issue is whether the
contract is ambiguous and, if it is not, what obligations it imposes on the parties.
This is a matter of law. See Cent. States, Se. & Sw. Areas Pension Fund v. Waste
Mgmt. of Michigan, Inc., 674 F.3d 630, 634-35 (7th Cir. 2012). As a result, “the task

4Relying

on Sunstream Jet Express, Inc. v. International Air Service Co., 734 F.2d
1258, 1266 (7th Cir. 1984), AAC incorrectly contends that “Illinois decisional law provides
that even when a contract is integrated on its face, it might require discovery and trial to
determine its proper construction.” Defs.’ Reply Br. at 5 (internal quotation marks omitted).
That was the case when Sunstream was decided, but the Illinois Supreme Court has since
expressly disavowed this “provisional admission approach” of interpreting expressly
integrated contracts. See Air Safety, 706 N.E.2d at 885; see also River’s Edge Homeowners’
Ass’n v. City of Naperville, 819 N.E.2d 806, 810 (Ill. App. Ct. 2004).

8

of drawing reasonable inferences … [is] greatly simplified,” because those inferences
are irrelevant to the matter at hand. See Bechtold v. Physicians Health Plan of N.
Ind., 1993 WL 625573, at *3 n.3 (N.D. Ind. Mar. 19, 1993), aff’d, 19 F.3d 322 (7th
Cir. 1994) (resolving cross-motions for judgment on the pleadings in breach of
contract claim).
What AAC means to argue, perhaps, is not that the Opinion failed to draw
reasonable factual inferences in its favor, but that the Opinion should have held
that AAC’s interpretation is a reasonable one. Contrary to AAC’s assertion that the
Opinion “fail[ed] to undertake that analysis” at all, see Defs.’ Reply Br. at 2-3, the
Opinion explicitly stated that “the definitional text and other provisions of the
Settlement Agreement dictate only one reasonable reading,” requiring AAC to
continue paying royalties on the disputed Part Numbers. 3/8/17 Op. at 11 (emphasis
added). That is, the Court considered AAC’s interpretation and rejected it as
unreasonable. Id.; see also Thompson v. Gordon, 948 N.E.2d 39, 48 (Ill. 2011) (“a
contract is not rendered ambiguous merely because the parties disagree on its
meaning”). There was no mistake in apprehension, so this argument cannot support
a motion for reconsideration.5 See Bank of Waunakee, 906 F.2d at 1191.

5AAC

also argues that the Opinion made an error of apprehension when it
(allegedly) construed the parties’ dispute as involving the overall validity of the ’089, ’910,
and ’231 Patents. Defs.’ Br. at 10 (citing 3/8/17 Op. at 11 (“The parties differ over whether
the definition of the Royalty Products, be they in the First Tier or Second Tier, are
dependent on the validity of the various patents. Nothing in the text of the definitions
suggests that validity of the patents matters … .” (emphasis in original))). In context,
“validity of … the patents” plainly means the validity of the various claims of the patents.
The parties and the Court all acknowledged the overall validity of the ’089 and ’231 Patents
(and neither party mentioned any reexamination of the ’910 Patent, nor did the Court). See
3/8/17 Op. at 6-7 (noting that at least some claims of the ’089 and ’231 Patents survive).

9

B. Failure to Consider the Patent Misuse Doctrine
AAC’s second argument for reconsideration has more force. Specifically, AAC
contends that, even if the language of the Settlement Agreement otherwise supports
Knowles’ interpretation, that interpretation is unreasonable because it violates
federal patent policy. Defs.’ Br. at 10-13. The prior Opinion did not address this
argument, but the Court will do so here.
Federal law prohibits “patent misuse,” which “occurs when the scope of an
otherwise valid patent monopoly extends beyond the prescribed boundaries of the
patentee’s control.” Ocean Tomo, LLC v. Barney, 133 F. Supp. 3d 1107, 1118 (N.D.
Ill. 2015) (citations omitted). One form of per se patent misuse is an “arrangement[]
in which a patentee effectively extends the term of its patent by requiring postexpiration royalties.” Cnty. Materials Corp. v. Allan Block Corp., 502 F.3d 730, 734
(7th Cir. 2007) (citations omitted). This rule was first articulated in Brulotte v. Thys
Co., where the Supreme Court deemed unenforceable a patent license for the use of
farm machinery insofar as the license required the licensees to pay royalties
accrued “after the last of the patents incorporated into the machines had expired.”
379 U.S. 29, 30 (1964). Recently, the Supreme Court confirmed that Brulotte
remained good law and applied its holding to a settlement agreement that
contained a royalty-bearing patent license. Kimble v. Marvel Entm’t, LLC, 135 S.
Ct. 2401 (2015).
With both parties and the Court accepting the validity of the patents, the change in
circumstance that prompted this dispute could only concern the validity of various patent
claims. Indeed, based on the motion for reconsideration and its corresponding briefs, AAC
appears to have well understood the Opinion’s use of “validity” as referring to “claim
validity.”

10

AAC contends that, if the Settlement Agreement is interpreted to require
royalties on Part Numbers no longer covered by a valid claim, the royalty provisions
will run afoul of Brulotte and Kimble and constitute patent misuse. Defs.’ Br. at 1013; R. 285, Defs.’ Mot. for J. on the Pleadings Resp. Br. at 8-9. Because it is
unreasonable to interpret a contract as leading to illegal results, AAC argues,
Knowles’ interpretation of the Settlement Agreement cannot be correct.
But there are several problems with this argument. To start (and discussed
in more detail below), Brulotte and Kimble address the accrual of royalties on
expired patents. They do not consider royalties stemming from cancelled claims of
otherwise valid, unexpired patents. The federal courts of appeals have addressed
cases with facts that come closer to this particular situation, but none has read
Brulotte and Kimble as requiring it to strike down settlement provisions calling for
royalties on cancelled claims. (In fact, some cases suggest that collecting royalties
on products covered by cancelled claims does not constitute patent misuse if the
patent itself remains valid.) Finally, the reasoning behind the Supreme Court’s
recent decision to approve Brulotte weighs in favor of allowing Knowles to continue
collecting royalties on the disputed Part Numbers, even if they are not covered by
the reexamined ’089 Patent. The Court will address each of these issues in turn.
1. Brulotte and Kimble
At first glance, Kimble appears a close analogue to the present case. There, as
here, the dispute arose out of a settlement agreement that resolved a patent-related
litigation between the parties. Kimble, 135 S. Ct. at 2406. In the settlement, the
11

alleged infringer purchased the patent at issue and agreed to pay the patent holder
a royalty on all future sales of products using that patent. Id. The parties soon
disagreed as to the proper calculation of royalties, however, and the patent holder
sued for breach of the settlement agreement. Kimble v. Marvel Enters., Inc., 727
F.3d 856, 859 (9th Cir. 2013). The purchaser countersued for a declaratory
judgment that it had no obligation to pay royalties past the date that the patent
was to expire. Id..
The case ended up in front of the Supreme Court, where the purchaser
argued for the overruling of Brulotte (which had attracted extensive criticism over
the decades). Brulotte’s detractors argued that the decision amounted to an
economically unsound restraint on the freedom to enter contracts. See Kimble, 135
S. Ct. at 2406; see also, e.g., Scheiber v. Dolby Labs., Inc., 293 F.3d 1014, 1017-18
(7th Cir. 2002). But the Supreme Court declined to jettison Brulotte, reasoning that
(1) Brulotte’s doctrinal underpinnings had not changed, so there was no statutory
basis to ignore stare decisis; and (2) even if the economic assumptions behind
Brulotte were misguided, the ruling provided a useful bright-line rule that was easy
for judges to apply and for parties to contract around. Kimble, 135 S. Ct. 2401. So
the Supreme Court reaffirmed Brulotte and held that post-expiration royalties could
not be enforced. Id. at 2411.
AAC cites Brulotte and Kimble as part of its argument against Knowles’
interpretation of the Settlement Agreement. That is, Knowles’ interpretation of the
Agreement cannot be reasonable, because it is—according to AAC—contrary to the

12

holdings of these two cases. Defs.’ Br. at 10; Defs.’ Mot. for J. on the Pleadings Resp.
Br. at 8. It is true that, “[a]s a general principle of contract law, statutes and laws in
existence at the time a contract is executed are considered part of the contract. It is
presumed that parties contract with knowledge of the existing law.” Braye v.
Archer-Daniels-Midland Co., 676 N.E.2d 1295, 1303 (Ill. 1997) (citations omitted).
In Illinois, contract interpretations that “render[] the agreement enforceable rather
than void [are] preferred.” Id. (citation omitted); see also FutureSource LLC v.
Reuters Ltd., 312 F.3d 281, 285 (7th Cir. 2002) (“Nonsensical interpretations of
contracts … are disfavored … because people are unlikely to make contracts … that
they believe will have absurd consequences.”). But—importantly—“the contractual
language [must] reasonably allow[] such an interpretation.” Lo v. Provena Covenant
Medical Center, 796 N.E.2d 607, 615 (Ill. App. Ct. 2003) (emphasis added). And the
Court has already held that AAC’s interpretation of the Settlement Agreement is
not reasonable. 3/8/17 Op. at 11.
What’s more, “a contract should not be deemed illegal unless it is expressly
contrary to the law or public policy.” Braye, 676 N.E.2d at 1303 (emphasis added).
Because of the importance of the freedom to enter contracts, “the power to declare a
private contract invalid on public policy grounds is exercised sparingly.” Phoenix
Ins. Co. v. Rosen, 949 N.E.2d 639, 645 (Ill. 2011). But neither Brulotte nor Kimble
directly prohibits Knowles from collecting royalties on the disputed Part Numbers,
even if they are no longer covered by the reexamined ’089 Patent. Both of those
cases involved disputes over post-expiration royalties. Kimble, 135 S. Ct. at 2411;

13

Brulotte, 379 U.S. at 33-34. The Settlement Agreement complies with their
holdings: AAC need pay royalties only “until expiration of … [the] ’231 Patent” (for
First Tier Royalty Products) and “until expiration of the last to expire of any ’089
and ’910 Patent” (for Second Tier Royalty Products). Settlement Agreement § 2.32.6. But neither Brulotte nor Kimble extends its holding to royalty obligations
arising out of invalidated claims of unexpired patents.6 As a result, they are not
controlling (much less “expressly” so) on the facts of this case.
AAC also cites Lear, Inc. v. Adkins for the proposition that a licensee cannot
be forced to pay royalties “without regard to the validity of the Patent Office’s
grant.” Defs.’ Br. at 11 n.1 (citing 395 U.S. 653, 672 (1969)). But Lear, too, is
distinguishable. First of all, Lear involved a discrete patent license, 395 U.S. at 657,
not a settlement agreement,7 see Settlement Agreement at Preamble (noting that
the Agreement’s purpose is to “settle and resolve the Litigation and to reduce the
possibility of any further litigation”8). Settlements versus patent licenses are

6In

fact, Brulotte envisioned a workaround of its bright-line rule (approvingly cited
in Kimble, 135 S. Ct. 2408) in which the parties license (and calculate royalties on) a bundle
of patents. 379 U.S. at 30. Then the royalties “may run until the latest-running patent
covered in the parties’ agreement expires.” Kimble, 135 S. Ct. at 2408. As applied to the
Settlement Agreement, this suggests that, even if the ’089 were entirely invalidated,
Knowles could arguably still collect royalties on Second Tier Royalty Products: AAC’s
royalty obligation continues “until expiration of the last to expire of any ’089 and ’910
Patent,” Settlement Agreement § 2.3-2.6, and there is no indication that the ’910 Patent has
expired or that any of its claims have been invalidated, see Knowles Compl. ¶ 180, Defs.’
Ans. ¶ 180.
7AAC represents that “[t]he Court … recognized the 2007 Agreement as a patent
license, even if it was born out of filed and threatened cases alleging infringement.” Defs.’
Reply Br. at 5. The Opinion did not do that. In fact, the Opinion referred to the agreement
as a “Settlement Agreement” throughout and characterized the license as but one “term[] of
the Settlement Agreement,” 3/8/17 Op. at 1 (emphasis added).
8AAC’s suggestion that the purpose of the Settlement Agreement was not to settle
the parties’ trade secrets and patent infringement claims, Defs.’ Reply Br. at 6-7

14

governed by different case law and different policy considerations. See Section
III.B.2. Secondly, Lear considered invalidation of the entire patent, not of a subset of
the patent claims. 395 U.S. at 658. As AAC has acknowledged itself, Knowles’
patents “remain valid” and there is a material difference between an entirely
invalid patent and the invalidity of specific claims within a patent. See Defs.’ Br. at
10 (arguing that the Court erred by misapprehending the parties’ dispute as one of
patent validity, not the “scope of the claims of the identified patent”). So none of the
three Supreme Court cases on which AAC relies directly governs this dispute.
That said, even if Knowles’ interpretation of the Agreement should not be
disfavored because it is not “clearly contrary” to the authorities cited by AAC, see
Phoenix Ins., 949 N.E.2d at 645, additional analysis of Brulotte and Kimble’s
progeny is needed. The Court must determine if judgment was properly granted in
Knowles’ favor on AAC’s claims for declaratory judgment of no royalties owed on the
’089 and ’231 Patents. See Pl.’s Mot. for J. on the Pleadings; Defs.’ Countercl. ¶¶ 4752 (Count 3), ¶¶ 53-59 (Count 4). That is because, even if the Agreement required
payment of royalties on specific Part Numbers covered by invalidated claims, that

(characterizing Knowles’ trade secrets complaint as “a dead letter, with little settlement
value”), is not reasonable. The Agreement is titled “Settlement, Release, and Cross-License
Agreement” and states the parties’ intentions to “settle and resolve the Litigation and to
reduce the possibility of any future litigation,” Settlement Agreement at Preamble. The
Agreement itself was the product of “a series of settlement discussions and a mediation …
that ultimately led to the settlement herein.” Id. Its purpose could not be clearer. Perhaps
AAC means to imply that, of the settled claims, its claims against Knowles were more
meritorious than Knowles’ claims against AAC, so the impetus behind the settlement was
Knowles’ desire to avoid a judgment in AAC’s favor. But that does not square with the
Agreement’s asymmetric imposition of royalty obligations: AAC had to pay for the use of
Knowles’ patents, Settlement Agreement § 2.1, 2.3-2.6, but granted Knowles royalty-free
use of AAC’s patents, id. § 2.2.

15

provision would be unenforceable if it amounted to patent misuse. See Brulotte, 379
U.S. at 34; Kimble, 135 S. Ct. at 2406. So whatever interpretation of the Agreement
wins out, if there is case law that persuasively extends Brulotte’s reasoning to an
analogous situation, then there is no royalty obligation. The Supreme Court has not
answered the question at hand, so the Court now turns to other federal case law.
2. Application in Federal Courts
An examination of how the federal circuit courts have interpreted Brulotte,
Kimble, and Lear does not help AAC’s argument. No circuit court has held that
Brulotte and its kin prohibit a patent holder from collecting royalties, pursuant to a
settlement agreement, on products that are covered by cancelled claims of otherwise
unexpired patents. In fact, although there does not appear to be case law addressing
this exact situation, the case law that is available weighs in favor of Knowles.
The fact that AAC’s royalty obligations arise out of a settlement agreement
and not a pure patent license is crucial. Brulotte stressed the need to limit patent
holders from extending their monopolies beyond the statutory period so that they
cannot unduly constrain the “free market visualized for the post-expiration period.”
379 U.S. at 32. Later, in Kimble, the Supreme Court underscored the public interest
in “ensuring public access to discoveries” as an important policy goal driving its
decision to uphold Brulotte. 135 S. Ct. at 2406-07.
But in this case, there is another important policy goal in play. The federal
courts have consistently held that encouraging settlements is a significant interest
that can, at times, trump patent-law considerations. For example, although no16

challenges clauses (which bar licensees from challenging the validity of the licensed
patent) are unenforceable as part of stand-alone licensing agreements, Lear, 395
U.S. at 673-74, they are enforceable as part of settlements, see, e.g., Baseload
Energy, Inc. v. Roberts, 619 F.3d 1357, 1361 (Fed. Cir. 2010) (“Lear does not render
such [no-challenge] agreements unenforceable, because of the strong policy in favor
of settlement of litigation … .”). So “while the federal patent laws favor full and free
competition in the use of ideas in the public domain over the technical requirements
of contract doctrine, settlement of litigation is more strongly favored by the law.”
Flex-Foot, Inc. v. CRP, Inc., 238 F.3d 1362, 1369 (Fed. Cir. 2001) (citation omitted);
see also Ransburg Electro-Coating Corp. v. Spiller & Spiller, Inc., 489 F.2d 974, 978
(7th Cir. 1973) (federal patent “policy must occupy a subsidiary position to the
fundamental policy favoring the expedient and orderly settlement of disputes and
the fostering of judicial economy.”). So the conflict here is not between federal
patent policy and state contract law, as characterized by AAC, see Defs.’ Br. at 10,
but between federal patent policy and the policy “favor[ing] the finality of
judgments generally and the encouragement of settlements of litigation in
particular,” see Foster v. Hallco Mfg. Co., 947 F.2d 469, 477 (Fed. Cir. 1991).
Hemstreet v. Spiegel offers a look at how the conflict between these policies
has been resolved in practice. 851 F.2d 348 (Fed. Cir. 1988). There, the licensee
obtained a patent license—as part of a settlement agreement—and in exchange
promised to pay royalties “notwithstanding that said patents-in-suit may be held
invalid and/or unenforceable at any other proceeding at a later date.” Id. at 349.

17

Later on, the patents were held unenforceable in an unrelated federal lawsuit. Id.
So the licensee petitioned for relief from its obligation to make any future payments
under the settlement agreement, citing the outcome of the separate suit and
arguing that “it would be inconsistent with federal patent policy to require [the
licensee] to continue to pay royalties for a license under a patent that has been held
unenforceable.” Id. at 349-50. But the Federal Circuit rejected this argument,
concluding that the licensee was bound to the language of agreement. Id. at 351.
Hemstreet acknowledged the importance of the “public interest favoring full and free
competition in the use of ideas which are in reality a part of the public domain,” id.
(citing Lear, 395 U.S. at 670), but another interest superseded it: “the
encouragement of settlement of litigation and the need to enforce such settlements
in order to encourage the parties to enter into them,” Hemstreet, 851 F.2d at 350.9
Here, the Court has held that the terms of the Settlement Agreement
unambiguously require AAC to continue paying royalties on three Part Numbers

(SM0102B,

course, the apparent supremacy of settlement promotion over patent policy is not
absolute; after all, the perpetual-royalty clause rejected in Kimble was part of a settlement
agreement. See 135 S. Ct. at 2406. And Kimble was decided well after Hemstreet, so if the
two conflicted directly, Kimble would control. But there is no direct conflict in the
precedent. And the facts of Kimble were such that the balance between patent policy and
pro-settlement policy fell lopsidedly in favor of the former. There, the patent holder
attempted to obtain rights via settlement that it could never have held under the patent
statutes—that is, a perpetual right to exclude. Id. What’s more, the parties did not dispute
whether, independent of the settlement agreement, the allegedly infringing product would
be covered by the patent after expiration (it of course would not); so no judicial or litigative
resources were needed to litigate infringement or claim construction. Id.

18

§ 1.5(B), AAC “contractually agreed—in exchange for valuable consideration”—to
pay royalties on them “implicitly regardless of whether … [the claims covering
them] are valid or invalid.” See Panduit Corp. v. HellermannTyton Corp., 2004 WL
1898954, at *3 (N.D. Ill. Aug. 11, 2004) (settlement agreement continued to bar
alleged infringer from producing products “covered by any claim of” a disputed
patent during the reexamination process, so long as the patent remained “alive”);
3/8/17 Op. at 11. Because the Agreement settled pending litigation, Settlement
Agreement at Preamble (describing the purpose of the Agreement); § 3.2 (dismissal
of claims); § 4.1-4.3 (mutual releases), it served an important policy interest and the
parties ought to be bound to their obligations. AAC has not identified—nor has the

In fact, the way that the Agreement defines royalty-bearing products—listing
certain Part Numbers as First Tier or Second Tier Royalty Products to eliminate
any ambiguity as to their “covered” status—represents an additional safeguard
against running afoul of the patent-misuse doctrine. At least one circuit has allowed
parties to agree that certain products are covered by a patent—regardless of later
changes in the patent’s scope. In Cellport Sys., Inc. v. Peiker Acustic GMBH & Co.
KG, the Tenth Circuit held that, because the parties’ settlement agreement defined
certain products as utilizing the licensed technology, the court could order the
licensee to pay royalties on those products without conducting an infringement
analysis to determine if they actually fell under the patent’s claims. 762 F.3d 1016,

19

1022–23 (10th Cir. 2014) (as a general rule, “if a product does not infringe a patent,
then the patent holder cannot demand royalties,” but “that … does not prevent the
parties from agreeing that a royalty is due on a non-infringing product if doing so
would benefit the convenience of the parties”) (emphasis added); see also Glasstech,
Inc. v. AB Kyro OY, 1989 WL 151672, at *4 (N.D. Ohio May 13, 1989) (holding that,
where patent holder and licensee were party to a consent judgment stipulating that
the “patent is valid,” licensee was required to pay royalties on the patent “even
should the Patent Office reject the claims of the [] patent or a court find it to be
invalid”).
So in summary: there is reason to think that parties to a settlement
agreement can contractually stipulate that certain products are covered by a
patent—which AAC and Knowles appear to have done with Part Numbers
SM0102B, SM0401BL, and SDM0401B and the ’089 and ’910 Patents—despite
specific claims in the patents later being deemed invalid. In any case, the existing
case law does not explicitly prohibit the payment of royalties on products falling
outside a reexamined patent, where the underlying patent remains unexpired and
the payment obligations arise out of a settlement agreement. So Brulotte and
Kimble are distinguishable, and the Court’s “task is not to expand Brulotte’s holding
beyond its terms.” See Zila, Inc. v. Tinnell, 502 F.3d 1014, 1020 (9th Cir. 2007).
Unless “Brulotte and its progeny” directly apply, the Court “shall endeavor to give
effect to the intent of the parties and the bargain that they struck.” See id. (allowing
royalties beyond expiration of patents because the contract provided for royalties on

20

the sale of the invention not on “the claims described in and identified by the 1931
patent”).
3. Policy Considerations
There is another point in Knowles’s favor: allowing Knowles to enforce the
Settlement Agreement would mean applying a bright-line rule, and a similar goal of
simplicity also underlies Brulotte and Kimble. In Kimble, the Supreme Court
reaffirmed Brulotte in part because of the prior decision’s “workability.” 135 S. Ct.
at 2411. Brulotte was “simplicity itself to apply”: “A court need only ask whether a
licensing agreement provides royalties for post-expiration use of a patent. If not, no
problem; if so, no dice.” Id. This bright-line rule compared favorably against the
patent holder’s proposed alternative, which required an “elaborate inquiry” that
would produce “notoriously high litigation costs and unpredictable results.” Id.
(citation omitted).
Apply those considerations here: AAC urges that the Settlement Agreement
constitutes per se patent misuse, even though some of the patent’s claims are still
valid and unexpired. Under AAC’s proposed rule, even though a settlement
agreement expressly identified certain products as “covered by” a patent, the
accused infringer could in effect re-open the litigation every time a patent
underwent a reexamination resulting in the cancellation of some but not all of its
claims. All of the previously-agreed “covered” products would be up for grabs again.
The licensee could argue that any number of its previously royalty-bearing products
was covered only under a cancelled claim, so it no longer needs to pay. And the
21

patent holder would have no choice but to litigate the claim construction—not only
robbing the previous settlement of its finality, but eating up considerable judicial
and litigative resources. See Cassandra E. Havens, Saving Patent Law from
Competition Policy and Economic Theories: Kimble v. Marvel Entertainment, 31
Berkeley Tech. L.J. 371, 393 (2016) (noting that “efficiency is especially important”
“[i]n patent litigation” because “[p]atent trials require an additional procedure of
claim construction[,] … [t]he median time for a patent case to reach trial is 2.4
years, and the cost of patent litigation is also very high”).
Of course, the parties could try to work around this by agreeing ahead of time
that Product A is covered by Claim 1, Product B is covered by Claim 2, and so on.
But this would not necessarily keep a lid on litigation of what had been a settled
dispute. If the Patent and Trademark Office cancels a claim that covers a royaltytriggering product, then the patent holder can petition to add new claims to reencompass that product. See, e.g., Artemi Ltd. v. Safe-Strap Co., 2013 WL 6860734,
at *1, *4 (D.N.J. Dec. 30, 2013) (patent holder did not commit patent misuse when it
“sought reexamination of … [its] patent with the express purpose of re-writing the
patent claims to encompass” alleged infringer’s product (citing Morton Salt Co. v.
G.S. Suppiger Co., 314 U.S. 488, 492 (1942), abrogated on other grounds by Ill. Tool
Works Inc. v. Independent Ink, Inc., 547 U.S. 28 (2006))); Am. Med. Sys., Inc. v.
Laser Peripherals, LLC, 712 F. Supp. 2d 885, 923 (D. Minn. 2010) (although
defendant “discern[ed] a sinister motive in [plaintiff’s] amendment of claims during
the reexamination to cover the accused devices,” amendments were not improper);

22

Kingsdown Med. Consultants, Ltd. v. Hollister Inc., 863 F.2d 867, 874 (Fed. Cir.
1998) (it is not “in any manner improper to amend or insert claims intended to cover
a competitor’s product the applicant’s attorney has learned about during the
prosecution of a patent application”). In fact, that might have happened here:
although the PTO cancelled all but one of the ’089 Patent’s original claims, 3/5/14
Inter Partes Reexam. Cert. at 2, Knowles successfully added 31 additional claims,
4/2/14 Ex Parte Reexam. Cert. at 1. If the new claims are approved, then the parties
go back to claim construction—requiring their time and resources, as well as those
of the federal courts, to determine whether the disputed product falls under the new
claims. So adopting AAC’s proposed extension of Brulotte to the facts of this case
would achieve the opposite practical outcome: it would “make the law less, not
more, workable than it is now.” See Kimble, 135 S. Ct. at 2411.
Not only does AAC’s proposed rule lack Brulotte’s workability, it also
undermines another important value of the court system, namely, giving the parties
certainty. Brulotte’s bright-line rule allowed parties to bargain around it in order to
achieve their desired business ends. See Kimble, 135 S. Ct. at 2414 (“As we have
explained, Brulotte leaves open various ways—involving both licensing and other
business arrangements—to accomplish payment deferral and risk-spreading
alike.”); id. at 2408 (listing possible contractual workarounds). The contracting
parties know each licensed patent’s statutory expiration date with certainty. That
expiration date serves as a clean cut-off on royalty accrual. So the terrain is clear;
the parties need only agree as to their preferred route.

23

Not so under AAC’s proposal. Predicting the timing of a patent’s future
reexaminations and the outcomes of those reexaminations is far harder than
determining a patent’s expiration date—especially because challenges can come not
just from the accused infringer in a particular lawsuit, but from non-parties to the
litigation as well. So the scope of a patent holder’s and would-be licensee’s
respective property rights is murky under AAC’s proposal. This, combined with the
high transaction costs of litigating a post-reexamination claim construction (as
discussed above), makes the bargains envisioned in Kimble very difficult to achieve.
Indeed, it is far from clear that AAC’s proposal actually would end-up
benefitting patent licensees. True, if some of a patent’s claims are later invalidated,
that may free a licensee from its contractual obligation to pay royalties on products
that were covered under the cancelled claims. But this is an entirely ex post
perspective. Consider the contractual incentives before a settlement agreement is
arrived at: knowing that a later reexamination may render the royalty provisions of
a settlement agreement unenforceable, a patent holder might very well demand a
higher royalty in order to settle, or demand a front-loaded payment schedule, or
both. The costs of introducing uncertainty into the length of a product’s royaltybearing life could end-up being borne by licensees. In the case of cash-poor licensees,
it might cut them out of otherwise mutually beneficial settlement agreements
altogether.
One final note: a common concern with affirming (or, in this case, declining to
narrow) patent rights is the potential to stifle innovation by protecting

24

unmeritorious patents. But that is not a problem here. If certain patent claims are
so obviously weak that an accused infringer can reasonably anticipate their
subsequent cancellation, then the infringer’s rational move is not to settle the claim,
pay royalties, and hope that someone else petitions the PTO to reexamine those
exact claims. It is to file the reexamination petition itself, or litigate the invalidity of
the particular claims in the district court case. Rejecting AAC’s patent-misuse
argument does not protect weak patents; it merely holds AAC to the bargain it
struck, instead of allowing it to re-open, in effect, the settled litigation due to
cancellation of some of the claims in two of the patents.
IV. Conclusion
For the reasons stated above, AAC’s motion for reconsideration, R. 301, is
denied.
