CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR
THE FEDERAL CIRCUIT
No. 06–937. Argued January 16, 2008—Decided June 9, 2008
The longstanding doctrine of patent exhaustion limits the patent rights
that survive the initial authorized sale of a patented item. Respon-
dent (LGE) purchased, inter alia, the computer technology patents at
issue (LGE Patents): One discloses a system for ensuring that most
current data are retrieved from main memory, one relates to the co-
ordination of requests to read from and write to main memory, and
one addresses the problem of managing data traffic on a set of wires,
or “bus,” connecting two computer components. LGE licensed the
patents to Intel Corporation (Intel), in an agreement (License Agree-
ment) that authorizes Intel to manufacture and sell microprocessors
and chipsets using the LGE Patents (Intel Products) and that does
not purport to alter patent exhaustion rules. A separate agreement
(Master Agreement) required Intel to give its customers written no-
tice that the license does not extend to a product made by combining
an Intel Product with a non-Intel product, and provided that a
breach of the agreement would not affect the License Agreement. Pe-
titioner computer manufacturers (Quanta) purchased microproces-
sors and chipsets from Intel. Quanta then manufactured computers
using Intel parts in combination with non-Intel parts, but did not
modify the Intel components. LGE sued, asserting that this combina-
tion infringed the LGE Patents. The District Court granted Quanta
summary judgment, but on reconsideration, denied summary judg-
ment as to the LGE Patents because they contained method claims.
The Federal Circuit affirmed in part and reversed in part, agreeing
with the District Court that the patent exhaustion doctrine does not
apply to method patents, which describe operations to make or use a
product; and concluding, in the alternative, that exhaustion did not

Syllabus
apply because LGE did not license Intel to sell the Intel Products to
Quanta to combine with non-Intel products.
Held: Because the doctrine of patent exhaustion applies to method pat-
ents, and because the License Agreement authorizes the sale of com-
ponents that substantially embody the patents in suit, the exhaus-
tion doctrine prevents LGE from further asserting its patent rights
with respect to the patents substantially embodied by those products.
Pp. 5–19.
(a) The patent exhaustion doctrine provides that a patented item’s
initial authorized sale terminates all patent rights to that item. See,
e.g., Bloomer v. McQuewan, 14 How. 539. In the Court’s most recent
discussion of the doctrine, United States v. Univis Lens Co., 316 U. S.
241, patents for finished eyeglass lenses, held by the respondent
(Univis), did not survive the sale of lens blanks by the licensed manu-
facturer to wholesalers and finishing retailers who ground the blanks
into patented finished lenses. The Court assumed that Univis’ pat-
ents were practiced in part by the wholesalers and finishing retailers,
concluding that the traditional bar on patent restrictions following an
item’s sale applies when the item sufficiently embodies the patent—
even if it does not completely practice the patent—such that its only
and intended use is to be finished under the patent’s terms. The par-
ties’ arguments here are addressed with this patent exhaustion his-
tory in mind. Pp. 5–8.
(b) Nothing in this Court’s approach to patent exhaustion supports
LGE’s argument that method claims, as a category, are never ex-
haustible. A patented method may not be sold in the same way as an
article or device, but methods nonetheless may be “embodied” in a
product, the sale of which exhausts patent rights. The Court has re-
peatedly found method patents exhausted by the sale of an item em-
bodying the method. See Ethyl Gasoline Corp. v. United States, 309
U. S. 436, 446, 457; Univis, supra, at 248–251. These cases rest on
solid footing. Eliminating exhaustion for method patents would seri-
ously undermine the exhaustion doctrine, since patentees seeking to
avoid exhaustion could simply draft their claims to describe a method
rather than an apparatus. On LGE’s theory here, for example, al-
though Intel is authorized to sell a completed computer system that
practices the LGE Patents, downstream purchasers could be liable
for patent infringement, which would violate the longstanding prin-
ciple that, when a patented item is “once lawfully made and sold,
there is no restriction on [its] use to be implied for the [patentee’s]
benefit,” Adams v. Burke, 17 Wall. 453, 457. Pp. 9–11.
(c) The Intel Products embodied the patents here. Univis governs
this case. There, exhaustion was triggered by the sale of the lens
blanks because their only reasonable and intended use was to prac-

Syllabus
tice the patent and because they “embodie[d] essential features of
[the] patented invention,” 316 U. S., at 249–251. Each of those at-
tributes is shared by the microprocessors and chipsets Intel sold to
Quanta under the License Agreement. First, LGE has suggested no
reasonable use for the Intel Products other than incorporating them
into computer systems that practice the LGE Patents: A microproces-
sor or chipset cannot function until it is connected to buses and mem-
ory. And as in Univis, the only apparent object of Intel’s sales was to
permit Quanta to incorporate the Intel Products into computers that
would practice the patents. Second, like the Univis lens blanks, the
Intel Products constitute a material part of the patented invention
and all but completely practice the patent. The only step necessary
to practice the patent is the application of common processes or the
addition of standard parts. Everything inventive about each patent
is embodied in the Intel Products. LGE’s attempts to distinguish
Univis are unavailing. Pp. 11–16.
(d) Intel’s sale to Quanta exhausted LGE’s patent rights. Exhaus-
tion is triggered only by a sale authorized by the patent holder.
Univis, supra, at 249. LGE argues that this sale was not authorized
because the License Agreement does not permit Intel to sell its prod-
ucts for use in combination with non-Intel products to practice the
LGE Patents. But the License Agreement does not restrict Intel’s
right to sell its products to purchasers who intend to combine them
with non-Intel parts. Intel was required to give its customers notice
that LGE had not licensed those customers to practice its patents,
but neither party contends that Intel breached that agreement. In
any event, the notice provision is in the Master Agreement, and LGE
does not suggest that a breach of that agreement would constitute a
License Agreement breach. Contrary to LGE’s position, the question
whether third parties may have received implied licenses is irrele-
vant, because Quanta asserts its right to practice the patents based
not on implied license but on exhaustion, and exhaustion turns only
on Intel’s own license to sell products practicing the LGE Patents.
LGE’s alternative argument, invoking the principle that patent ex-
haustion does not apply to postsale restrictions on “making” an arti-
cle, is simply a rephrasing of its argument that combining the Intel
Products with other components adds more than standard finishing
to complete a patented article. Pp. 16–18.

ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF
APPEALS FOR THE FEDERAL CIRCUIT
[June 9, 2008]
JUSTICE THOMAS delivered the opinion of the Court.
For over 150 years this Court has applied the doctrine of
patent exhaustion to limit the patent rights that survive
the initial authorized sale of a patented item. In this case,
we decide whether patent exhaustion applies to the sale of
components of a patented system that must be combined
with additional components in order to practice the pat-
ented methods. The Court of Appeals for the Federal
Circuit held that the doctrine does not apply to method
patents at all and, in the alternative, that it does not
apply here because the sales were not authorized by the
license agreement. We disagree on both scores. Because
the exhaustion doctrine applies to method patents, and
because the license authorizes the sale of components that
substantially embody the patents in suit, the sale ex-
hausted the patents.
I
Respondent LG Electronics, Inc. (LGE), purchased a
portfolio of computer technology patents in 1999, including
the three patents at issue here: U. S. Patent Nos.
4,939,641 (’641); 5,379,379 (’379); and 5,077,733 (’733)
2 QUANTA COMPUTER, INC. v. LG ELECTRONICS, INC.
Opinion of the Court
(collectively LGE Patents). The main functions of a com-
puter system are carried out on a microprocessor, or cen-
tral processing unit, which interprets program instruc-
tions, processes data, and controls other devices in the
system. A set of wires, or bus, connects the microprocessor
to a chipset, which transfers data between the microproc-
essor and other devices, including the keyboard, mouse,
monitor, hard drive, memory, and disk drives.
The data processed by the computer are stored princi-
pally in random access memory, also called main memory.
Webster’s New World Dictionary of Computer Terms 334,
451 (8th ed. 2000). Frequently accessed data are generally
stored in cache memory, which permits faster access than
main memory and is often located on the microprocessor
itself. Id., at 84. When copies of data are stored in both
the cache and main memory, problems may arise when
one copy is changed but the other still contains the origi-
nal “stale” version of the data. J. Handy, Cache Memory
Book 124 (2d ed. 1993). The ’641 patent addresses this
problem. It discloses a system for ensuring that the most
current data are retrieved from main memory by monitor-
ing data requests and updating main memory from the
cache when stale data are requested. LG Electronics, Inc.
v. Bizcom Electronics, Inc., 453 F. 3d 1364, 1377 (CA Fed.
2006).
The ’379 patent relates to the coordination of requests to
read from, and write to, main memory. Id., at 1378.
Processing these requests in chronological order can slow
down a system because read requests are faster to execute
than write requests. Processing all read requests first
ensures speedy access, but may result in the retrieval of
outdated data if a read request for a certain piece of data
is processed before an outstanding write request for the
same data. The ’379 patent discloses an efficient method
of organizing read and write requests while maintaining
accuracy by allowing the computer to execute only read

Opinion of the Court
requests until it needs data for which there is an out-
standing write request. LG Electronics, Inc. v. Asustek
Computer, Inc., No. C 01–02187 CW et al., Order Constru-
ing Disputed Terms and Phrases, p. 42 (ND Cal., Aug. 20,
2002). Upon receiving such a read request, the computer
executes pending write requests first and only then re-
turns to the read requests so that the most up-to-date data
are retrieved. Ibid.
The ’733 patent addresses the problem of managing the
data traffic on a bus connecting two computer components,
so that no one device monopolizes the bus. It allows mul-
tiple devices to share the bus, giving heavy users greater
access. This patent describes methods that establish a
rotating priority system under which each device alter-
nately has priority access to the bus for a preset number of
cycles and heavier users can maintain priority for more
cycles without “hogging” the device indefinitely. Id., at
37–38.
LGE licensed a patent portfolio, including the LGE
Patents, to Intel Corporation (Intel). The cross-licensing
agreement (License Agreement) permits Intel to manufac-
ture and sell microprocessors and chipsets that use the
LGE Patents (the Intel Products). The License Agreement
authorizes Intel to “ ‘make, use, sell (directly or indirectly),
offer to sell, import or otherwise dispose of’ ” its own prod-
ucts practicing the LGE Patents. Brief for Petitioners 8
(quoting App. 154).1 Notwithstanding this broad lan-
guage, the License Agreement contains some limitations.
Relevant here, it stipulates that no license
“ ‘is granted by either party hereto . . . to any third
party for the combination by a third party of Licensed
Products of either party with items, components, or
the like acquired . . . from sources other than a party

Opinion of the Court
hereto, or for the use, import, offer for sale or sale of
such combination.’ ” Brief for Petitioners 8 (quoting
App. 164).
The License Agreement purports not to alter the usual
rules of patent exhaustion, however, providing that,
“ ‘[n]otwithstanding anything to the contrary contained in
this Agreement, the parties agree that nothing herein
shall in any way limit or alter the effect of patent exhaus-
tion that would otherwise apply when a party hereto sells
any of its Licensed Products.’ ” Brief for Petitioners 8
(quoting App. 164).
In a separate agreement (Master Agreement), Intel
agreed to give written notice to its own customers inform-
ing them that, while it had obtained a broad license “ ‘en-
sur[ing] that any Intel product that you purchase is li-
censed by LGE and thus does not infringe any patent held
by LGE,’ ” the license “ ‘does not extend, expressly or by
implication, to any product that you make by combining
an Intel product with any non-Intel product.’ ” Brief for
Respondent 9 (emphasis deleted) (quoting App. 198). The
Master Agreement also provides that “ ‘a breach of this
Agreement shall have no effect on and shall not be
grounds for termination of the Patent License.’ ” Brief for
Petitioners 9 (quoting App. 176).
Petitioners, including Quanta Computer (collectively
Quanta), are a group of computer manufacturers. Quanta
purchased microprocessors and chipsets from Intel and
received the notice required by the Master Agreement.
Nonetheless, Quanta manufactured computers using Intel
parts in combination with non-Intel memory and buses in
ways that practice the LGE Patents. Quanta does not
modify the Intel components and follows Intel’s specifica-
tions to incorporate the parts into its own systems.
LGE filed a complaint against Quanta, asserting that
the combination of the Intel Products with non-Intel mem-
Cite as: 553 U. S. ____ (2008) 5
Opinion of the Court
ory and buses infringed the LGE Patents. The District
Court granted summary judgment to Quanta, holding
that, for purposes of the patent exhaustion doctrine, the
license LGE granted to Intel resulted in forfeiture of any
potential infringement actions against legitimate purchas-
ers of the Intel Products. LG Electronics, Inc. v. Asustek
Computer, Inc., 65 USPQ 2d 1589, 1593, 1600 (ND Cal.
2002). The court found that, although the Intel Products
do not fully practice any of the patents at issue, they have
no reasonable noninfringing use and therefore their au-
thorized sale exhausted patent rights in the completed
computers under United States v. Univis Lens Co., 316
U. S. 241 (1942). Asustek, supra, at 1598–1600. In a
subsequent order limiting its summary judgment ruling,
the court held that patent exhaustion applies only to
apparatus or composition-of-matter claims that describe a
physical object, and does not apply to process, or method,
claims that describe operations to make or use a product.
LG Electronics, Inc. v. Asustek Computer, Inc., 248
F. Supp. 2d 912, 918 (ND Cal. 2003). Because each of the
LGE Patents includes method claims, exhaustion did not
apply.
The Court of Appeals for the Federal Circuit affirmed in
part and reversed in part. It agreed that the doctrine of
patent exhaustion does not apply to method claims. In the
alternative, it concluded that exhaustion did not apply
because LGE did not license Intel to sell the Intel Products
to Quanta for use in combination with non-Intel products.

The longstanding doctrine of patent exhaustion provides
that the initial authorized sale of a patented item termi-
nates all patent rights to that item. This Court first ap-
plied the doctrine in 19th-century cases addressing patent

Opinion of the Court
extensions on the Woodworth planing machine. Purchas-
ers of licenses to sell and use the machine for the duration
of the original patent term sought to continue using the
licenses through the extended term. The Court held that
the extension of the patent term did not affect the rights
already secured by purchasers who bought the item for
use “in the ordinary pursuits of life.” Bloomer v. McQue-
wan, 14 How. 539, 549 (1853); see also ibid. (“[W]hen the
machine passes to the hands of the purchaser, it is no
longer within the limits of the monopoly”); Bloomer v.
Millinger, 1 Wall. 340, 351 (1864). In Adams v. Burke, 17
Wall. 453 (1873), the Court affirmed the dismissal of a
patent holder’s suit alleging that a licensee had violated
postsale restrictions on where patented coffin-lids could be
used. “[W]here a person ha[s] purchased a patented ma-
chine of the patentee or his assignee,” the Court held, “this
purchase carrie[s] with it the right to the use of that ma-
chine so long as it [is] capable of use.” Id., at 455.
Although the Court permitted postsale restrictions on
the use of a patented article in Henry v. A. B. Dick Co.,
224 U. S. 1 (1912),2 that decision was short lived. In 1913,
the Court refused to apply A. B. Dick to uphold price-
fixing provisions in a patent license. See Bauer & Cie v.
O’Donnell, 229 U. S. 1, 14–17 (1913). Shortly thereafter,
in Motion Picture Patents Co. v. Universal Film Mfg. Co.,
243 U. S. 502, 518 (1917), the Court explicitly overruled
——————
2 The A. B. Dick Company sold mimeograph machines with an at-
tached license stipulating that the machine could be used only with ink,
paper, and other supplies made by the A. B. Dick Company. The Court
rejected the notion that a patent holder “can only keep the article
within the control of the patent by retaining the title,” A. B. Dick, 224
U. S., at 18, and held that “any . . . reasonable stipulation, not inher-
ently violative of some substantive law” was “valid and enforceable,”
id., at 31. The only requirement, the Court held, was that “the pur-
chaser must have notice that he buys with only a qualified right of use,”
so that a sale made without conditions resulted in “an unconditional
title to the machine, with no limitations upon the use.” Id., at 26.

Opinion of the Court
A. B. Dick. In that case, a patent holder attempted to
limit purchasers’ use of its film projectors to show only
film made under a patent held by the same company. The
Court noted the “increasing frequency” with which patent
holders were using A. B. Dick-style licenses to limit the
use of their products and thereby using the patents to
secure market control of related, unpatented items. 243
U. S., at 509, 516–517. Observing that “the primary pur-
pose of our patent laws is not the creation of private for-
tunes for the owners of patents but is ‘to promote the
progress of science and useful arts,’ ” id., at 511 (quoting
U. S. Const., Art. I, §8, cl. 8), the Court held that “the
scope of the grant which may be made to an inventor in a
patent, pursuant to the [patent] statute, must be limited
to the invention described in the claims of his patent.” 243
U. S., at 511. Accordingly, it reiterated the rule that “the
right to vend is exhausted by a single, unconditional sale,
the article sold being thereby carried outside the monopoly
of the patent law and rendered free of every restriction
which the vendor may attempt to put upon it.” Id., at 516.
This Court most recently discussed patent exhaustion in
Univis, 316 U. S. 241, on which the District Court relied.
Univis Lens Company, the holder of patents on eyeglass
lenses, licensed a purchaser to manufacture lens blanks3
by fusing together different lens segments to create bi-
and tri-focal lenses and to sell them to other Univis licen-
sees at agreed-upon rates. Wholesalers were licensed to
grind the blanks into the patented finished lenses, which
they would then sell to Univis-licensed prescription retail-
ers for resale at a fixed rate. Finishing retailers, after
grinding the blanks into patented lenses, would sell the
finished lenses to consumers at the same fixed rate. The
——————
3 Lens blanks are “rough opaque pieces of glass of suitable size, de-
sign and composition for use, when ground and polished, as multifocal
lenses in eyeglasses.” Univis, 316 U. S., at 244.
8 QUANTA COMPUTER, INC. v. LG ELECTRONICS, INC.
Opinion of the Court
United States sued Univis under the Sherman Act, 15
U. S. C. §§1, 3, 15, alleging unlawful restraints on trade.
Univis asserted its patent monopoly rights as a defense to
the antitrust suit. The Court granted certiorari to deter-
mine whether Univis’ patent monopoly survived the sale of
the lens blanks by the licensed manufacturer and there-
fore shielded Univis’ pricing scheme from the Sherman
Act.
The Court assumed that the Univis patents containing
claims for finished lenses were practiced in part by the
wholesalers and finishing retailers who ground the blanks
into lenses, and held that the sale of the lens blanks ex-
hausted the patents on the finished lenses. Univis, 316
U. S., at 248–249. The Court explained that the lens
blanks “embodi[ed] essential features of the patented
device and [were] without utility until . . . ground and
polished as the finished lens of the patent.” Id., at 249.
The Court noted that:
“where one has sold an uncompleted article which, be-
cause it embodies essential features of his patented
invention, is within the protection of his patent, and
has destined the article to be finished by the pur-
chaser in conformity to the patent, he has sold his in-
vention so far as it is or may be embodied in that par-
ticular article.” Id., at 250–251.
In sum, the Court concluded that the traditional bar on
patent restrictions following the sale of an item applies
when the item sufficiently embodies the patent—even if it
does not completely practice the patent—such that its only
and intended use is to be finished under the terms of the
patent.
With this history of the patent exhaustion doctrine in
mind, we turn to the parties’ arguments.

Opinion of the Court
III
A
LGE argues that the exhaustion doctrine is inapplicable
here because it does not apply to method claims, which are
contained in each of the LGE Patents. LGE reasons that,
because method patents are linked not to a tangible article
but to a process, they can never be exhausted through a
sale. Rather, practicing the patent—which occurs upon
each use of an article embodying a method patent—is
permissible only to the extent rights are transferred in an
assignment contract. Quanta, in turn, argues that there is
no reason to preclude exhaustion of method claims, and
points out that both this Court and the Federal Circuit
have applied exhaustion to method claims. It argues that
any other rule would allow patent holders to avoid exhaus-
tion entirely by inserting method claims in their patent
specifications.
Quanta has the better of this argument. Nothing in this
Court’s approach to patent exhaustion supports LGE’s
argument that method patents cannot be exhausted. It is
true that a patented method may not be sold in the same
way as an article or device, but methods nonetheless may
be “embodied” in a product, the sale of which exhausts
patent rights. Our precedents do not differentiate trans-
actions involving embodiments of patented methods or
processes from those involving patented apparatuses or
materials. To the contrary, this Court has repeatedly held
that method patents were exhausted by the sale of an item
that embodied the method. In Ethyl Gasoline Corp. v.
United States, 309 U. S. 436, 446, 457 (1940), for example,
the Court held that the sale of a motor fuel produced
under one patent also exhausted the patent for a method
of using the fuel in combustion motors.4 Similarly, as
——————
4 The patentee held patents for (1) a fluid additive increasing gasoline
efficiency, (2) motor fuel produced by mixing gasoline with the patented
10 QUANTA COMPUTER, INC. v. LG ELECTRONICS, INC.
Opinion of the Court
previously described, Univis held that the sale of optical
lens blanks that partially practiced a patent exhausted the
method patents that were not completely practiced until
the blanks were ground into lenses. 316 U. S., at 248–251.
These cases rest on solid footing. Eliminating exhaus-
tion for method patents would seriously undermine the
exhaustion doctrine. Patentees seeking to avoid patent
exhaustion could simply draft their patent claims to de-
scribe a method rather than an apparatus.5 Apparatus
and method claims “may approach each other so nearly
that it will be difficult to distinguish the process from the
function of the apparatus.” United States ex rel. Steinmetz
v. Allen, 192 U. S. 543, 559 (1904). By characterizing their
claims as method instead of apparatus claims, or including
a method claim for the machine’s patented method of
performing its task, a patent drafter could shield practi-
cally any patented item from exhaustion.
This case illustrates the danger of allowing such an end-
run around exhaustion. On LGE’s theory, although Intel
is authorized to sell a completed computer system that
practices the LGE Patents, any downstream purchasers of
the system could nonetheless be liable for patent in-

fluid, and (3) a method of using fuel containing the patented fluid in
combustion motors. Ethyl Gasoline Corp., 309 U. S., at 446. The
patentee sold only the fluid, but attempted to control sales of the
treated fuel. Id., at 459. The Court held that the sale of the fluid to
refiners relinquished the patentee’s exclusive rights to sell the treated
fuel. Id., at 457.
5 One commentator recommends this strategy as a way to draft pat-
ent claims that “will survive numerous transactions regarding the
patented good, allowing the force of the patent to intrude deeply into
the stream of commerce.” Thomas, Of Text, Technique, and the Tangi-
ble: Drafting Patent Claims Around Patent Rules, 17 J. Marshall J.
Computer & Info. L. 219, 252 (1998); see also id., at 225–226 (advocat-
ing the conversion of apparatus claims into method claims and noting
that “[e]ven the most novice claims drafter would encounter scant
difficulty in converting a patent claim from artifact to technique and
back again”).

Opinion of the Court
fringement. Such a result would violate the longstanding
principle that, when a patented item is “once lawfully
made and sold, there is no restriction on [its] use to be
implied for the benefit of the patentee.” Adams, 17 Wall.,
at 457. We therefore reject LGE’s argument that method
claims, as a category, are never exhaustible.
B
We next consider the extent to which a product must
embody a patent in order to trigger exhaustion. Quanta
argues that, although sales of an incomplete article do not
necessarily exhaust the patent in that article, the sale of
the microprocessors and chipsets exhausted LGE’s patents
in the same way the sale of the lens blanks exhausted the
patents in Univis. Just as the lens blanks in Univis did
not fully practice the patents at issue because they had
not been ground into finished lenses, Quanta observes, the
Intel Products cannot practice the LGE Patents—or in-
deed, function at all—until they are combined with mem-
ory and buses in a computer system. If, as in Univis,
patent rights are exhausted by the sale of the incomplete
item, then LGE has no postsale right to require that the
patents be practiced using only Intel parts. Quanta also
argues that exhaustion doctrine will be a dead letter
unless it is triggered by the sale of components that essen-
tially, even if not completely, embody an invention. Oth-
erwise, patent holders could authorize the sale of com-
puters that are complete with the exception of one minor
step—say, inserting the microprocessor into a socket—and
extend their rights through each downstream purchaser
all the way to the end user.
LGE, for its part, argues that Univis is inapplicable here
for three reasons. First, it maintains that Univis should
be limited to products that contain all the physical aspects
needed to practice the patent. On that theory, the Intel
Products cannot embody the patents because additional
12 QUANTA COMPUTER, INC. v. LG ELECTRONICS, INC.
Opinion of the Court
physical components are required before the patents can
be practiced. Second, LGE asserts that in Univis there
was no “patentable distinction” between the lens blanks
and the patented finished lenses since they were both
subject to the same patent. Brief for Respondent 14 (citing
Univis, supra, at 248–252). In contrast, it describes the
Intel Products as “independent and distinct products” from
the systems using the LGE Patents and subject to “inde-
pendent patents.” Brief for Respondent 13. Finally, LGE
argues that Univis does not apply because the Intel Prod-
ucts are analogous to individual elements of a combination
patent, and allowing sale of those components to exhaust
the patent would impermissibly “ascrib[e] to one element
of the patented combination the status of the patented
invention in itself.” Aro Mfg. Co. v. Convertible Top Re-
placement Co., 365 U. S. 336, 344–345 (1961).
We agree with Quanta that Univis governs this case. As
the Court there explained, exhaustion was triggered by
the sale of the lens blanks because their only reasonable
and intended use was to practice the patent and because
they “embodie[d] essential features of [the] patented in-
vention.” 316 U. S., at 249–251. Each of those attributes
is shared by the microprocessors and chipsets Intel sold to
Quanta under the License Agreement.
First, Univis held that “the authorized sale of an article
which is capable of use only in practicing the patent is a
relinquishment of the patent monopoly with respect to the
article sold.” Id., at 249. The lens blanks in Univis met
this standard because they were “without utility until
[they were] ground and polished as the finished lens of the
patent.” Ibid. Accordingly, “the only object of the sale
[was] to enable the [finishing retailer] to grind and polish
it for use as a lens by the prospective wearer.” Ibid. Here,
LGE has suggested no reasonable use for the Intel Prod-
ucts other than incorporating them into computer systems

Opinion of the Court
that practice the LGE Patents.6 Nor can we can discern
one: A microprocessor or chipset cannot function until it is
connected to buses and memory. And here, as in Univis,
the only apparent object of Intel’s sales to Quanta was to
permit Quanta to incorporate the Intel Products into
computers that would practice the patents.
Second, the lens blanks in Univis “embodie[d] essential
features of [the] patented invention.” Id., at 250–251. The
essential, or inventive, feature of the Univis lens patents
was the fusing together of different lens segments to cre-
ate bi- and tri-focal lenses. The finishing process per-
formed by the finishing and prescription retailers after the
fusing was not unique. As the United States explained:
“The finishing licensees finish Univis lens blanks in
precisely the same manner as they finish all other bi-
focal lens blanks. Indeed, appellees have never con-
tended that their licensing system is supported by
patents covering methods or processes relating to the
finishing of lens blanks. Consequently, it appears
that appellees perform all of the operations which con-
tribute any claimed element of novelty to Univis
lenses.” Brief for United States in United States v.
Univis Lens Co., O. T. 1941, No. 855 et al., p. 10 (foot-
note and citations omitted).

6 LGE suggests that the Intel Products would not infringe its patents
if they were sold overseas, used as replacement parts, or engineered so
that use with non-Intel Products would disable their patented features.
Brief for Respondent 21–22, n. 10. But Univis teaches that the ques-
tion is whether the product is “capable of use only in practicing the
patent,” not whether those uses are infringing. 316 U. S., at 249
(emphasis added). Whether outside the country or functioning as
replacement parts, the Intel Products would still be practicing the
patent, even if not infringing it. And since the features partially
practicing the patent are what must have an alternative use, suggest-
ing that they be disabled is no solution. The disabled features would
have no real use.
14 QUANTA COMPUTER, INC. v. LG ELECTRONICS, INC.
Opinion of the Court
While the Court assumed that the finishing process was
covered by the patents, Univis, supra, at 248–249, and the
District Court found that it was necessary to make a
working lens, United States v. Univis Lens Co., 41
F. Supp. 258, 262–263 (SDNY 1941), the grinding process
was not central to the patents. That standard process was
not included in detail in any of the patents and was not
referred to at all in two of the patents. Those that did
mention the finishing process treated it as incidental to
the invention, noting, for example, that “[t]he blank is
then ground in the usual manner,” U. S. Patent No.
1,876,497, p. 2, or simply that the blank is “then ground
and polished,” U. S. Patent No. 1,632,208, p. 1, Tr. of
Record in United States v. Univis Lens Co., O. T. 1941,
No. 855 et al., pp. 516, 498.
Like the Univis lens blanks, the Intel Products consti-
tute a material part of the patented invention and all but
completely practice the patent. Here, as in Univis, the
incomplete article substantially embodies the patent
because the only step necessary to practice the patent is
the application of common processes or the addition of
standard parts. Everything inventive about each patent is
embodied in the Intel Products. They control access to
main and cache memory, practicing the ’641 and ’379
patents by checking cache memory against main memory
and comparing read and write requests. They also control
priority of bus access by various other computer compo-
nents under the ’733 patent. Naturally, the Intel Products
cannot carry out these functions unless they are attached
to memory and buses, but those additions are standard
components in the system, providing the material that
enables the microprocessors and chipsets to function. The
Intel Products were specifically designed to function only
when memory or buses are attached; Quanta was not
required to make any creative or inventive decision when
it added those parts. Indeed, Quanta had no alternative

Opinion of the Court
but to follow Intel’s specifications in incorporating the
Intel Products into its computers because it did not know
their internal structure, which Intel guards as a trade
secret. Brief for Petitioners 3. Intel all but practiced the
patent itself by designing its products to practice the
patents, lacking only the addition of standard parts.
We are unpersuaded by LGE’s attempts to distinguish
Univis. First, there is no reason to distinguish the two
cases on the ground that the articles in Univis required
the removal of material to practice the patent while the
Intel Products require the addition of components to
practice the patent. LGE characterizes the lens blanks
and lenses as sharing a “basic nature” by virtue of their
physical similarity, while the Intel Products embody only
some of the “patentably distinct elements and steps” in-
volved in the LGE Patents. Brief for Respondent 26–27.
But we think that the nature of the final step, rather than
whether it consists of adding or deleting material, is the
relevant characteristic. In each case, the final step to
practice the patent is common and noninventive: grinding
a lens to the customer’s prescription, or connecting a
microprocessor or chipset to buses or memory. The Intel
Products embody the essential features of the LGE Pat-
ents because they carry out all the inventive processes
when combined, according to their design, with standard
components.
With regard to LGE’s argument that exhaustion does
not apply across patents, we agree on the general princi-
ple: The sale of a device that practices patent A does not,
by virtue of practicing patent A, exhaust patent B. But if
the device practices patent A while substantially embody-
ing patent B, its relationship to patent A does not prevent
exhaustion of patent B. For example, if the Univis lens
blanks had been composed of shatter-resistant glass under
patent A, the blanks would nonetheless have substantially
embodied, and therefore exhausted, patent B for the fin-
16 QUANTA COMPUTER, INC. v. LG ELECTRONICS, INC.
Opinion of the Court
ished lenses. This case is no different. While each Intel
microprocessor and chipset practices thousands of individ-
ual patents, including some LGE patents not at issue in
this case, the exhaustion analysis is not altered by the fact
that more than one patent is practiced by the same prod-
uct. The relevant consideration is whether the Intel Prod-
ucts that partially practice a patent—by, for example,
embodying its essential features—exhaust that patent.
Finally, LGE’s reliance on Aro is misplaced because that
case dealt only with the question whether replacement of
one part of a patented combination infringes the patent.
First, the replacement question is not at issue here. Sec-
ond, and more importantly, Aro is not squarely applicable
to the exhaustion of patents like the LGE Patents that do
not disclose a new combination of existing parts. Aro
described combination patents as “cover[ing] only the
totality of the elements in the claim [so] that no element,
separately viewed, is within the grant.” 365 U. S., at 344;
see also Mercoid Corp. v. Mid-Continent Investment Co.,
320 U. S. 661, 667–668 (1944) (noting that, in a combina-
tion patent, “the combination is the invention and it is
distinct from any” of its elements). Aro’s warning that no
element can be viewed as central to or equivalent to the
invention is specific to the context in which the combina-
tion itself is the only inventive aspect of the patent. In
this case, the inventive part of the patent is not the fact
that memory and buses are combined with a microproces-
sor or chipset; rather, it is included in the design of the
Intel Products themselves and the way these products
access the memory or bus.
C
Having concluded that the Intel Products embodied the
patents, we next consider whether their sale to Quanta
exhausted LGE’s patent rights. Exhaustion is triggered
only by a sale authorized by the patent holder. Univis,
Cite as: 553 U. S. ____ (2008) 17
Opinion of the Court
316 U. S., at 249.
LGE argues that there was no authorized sale here
because the License Agreement does not permit Intel to
sell its products for use in combination with non-Intel
products to practice the LGE Patents. It cites General
Talking Pictures Corp. v. Western Elec. Co., 304 U. S. 175
(1938), and General Talking Pictures Corp. v. Western
Elec. Co., 305 U. S. 124 (1938), in which the manufacturer
sold patented amplifiers for commercial use, thereby
breaching a license that limited the buyer to selling the
amplifiers for private and home use. The Court held that
exhaustion did not apply because the manufacturer had no
authority to sell the amplifiers for commercial use, and the
manufacturer “could not convey to petitioner what both
knew it was not authorized to sell.” General Talking
Pictures, supra, at 181. LGE argues that the same princi-
ple applies here: Intel could not convey to Quanta what
both knew it was not authorized to sell, i.e., the right to
practice the patents with non-Intel parts.
LGE overlooks important aspects of the structure of the
Intel-LGE transaction. Nothing in the License Agreement
restricts Intel’s right to sell its microprocessors and chip-
sets to purchasers who intend to combine them with non-
Intel parts. It broadly permits Intel to “ ‘make, use, [or]
sell’ ” products free of LGE’s patent claims. Brief for Peti-
tioners 8 (quoting App. 154). To be sure, LGE did require
Intel to give notice to its customers, including Quanta,
that LGE had not licensed those customers to practice its
patents. But neither party contends that Intel breached
the agreement in that respect. Brief for Petitioners 9;
Brief for Respondent 9. In any event, the provision requir-
ing notice to Quanta appeared only in the Master Agree-
ment, and LGE does not suggest that a breach of that
agreement would constitute a breach of the License
Agreement. Hence, Intel’s authority to sell its products
embodying the LGE Patents was not conditioned on the
18 QUANTA COMPUTER, INC. v. LG ELECTRONICS, INC.
Opinion of the Court
notice or on Quanta’s decision to abide by LGE’s directions
in that notice.
LGE points out that the License Agreement specifically
disclaimed any license to third parties to practice the
patents by combining licensed products with other compo-
nents. Brief for Petitioners 8. But the question whether
third parties received implied licenses is irrelevant be-
cause Quanta asserts its right to practice the patents
based not on implied license but on exhaustion. And
exhaustion turns only on Intel’s own license to sell prod-
ucts practicing the LGE Patents.
Alternatively, LGE invokes the principle that patent
exhaustion does not apply to postsale restrictions on “mak-
ing” an article. Brief for Respondent 43. But this is sim-
ply a rephrasing of its argument that combining the Intel
Products with other components adds more than standard
finishing to complete a patented article. As explained
above, making a product that substantially embodies a
patent is, for exhaustion purposes, no different from mak-
ing the patented article itself. In other words, no further
“making” results from the addition of standard parts—
here, the buses and memory—to a product that already
substantially embodies the patent.
The License Agreement authorized Intel to sell products
that practiced the LGE Patents. No conditions limited
Intel’s authority to sell products substantially embodying
the patents. Because Intel was authorized to sell its prod-
ucts to Quanta, the doctrine of patent exhaustion prevents
LGE from further asserting its patent rights with respect
to the patents substantially embodied by those products.7

7 We note that the authorized nature of the sale to Quanta does not
necessarily limit LGE’s other contract rights. LGE’s complaint does not
include a breach-of-contract claim, and we express no opinion on
whether contract damages might be available even though exhaustion
operates to eliminate patent damages. See Keeler v. Standard Folding
Bed Co., 157 U. S. 659, 666 (1895) (“Whether a patentee may protect

Opinion of the Court
IV
The authorized sale of an article that substantially
embodies a patent exhausts the patent holder’s rights and
prevents the patent holder from invoking patent law to
control postsale use of the article. Here, LGE licensed
Intel to practice any of its patents and to sell products
practicing those patents. Intel’s microprocessors and
chipsets substantially embodied the LGE Patents because
they had no reasonable noninfringing use and included all
the inventive aspects of the patented methods. Nothing in
the License Agreement limited Intel’s ability to sell its
products practicing the LGE Patents. Intel’s authorized
sale to Quanta thus took its products outside the scope of
the patent monopoly, and as a result, LGE can no longer
assert its patent rights against Quanta. Accordingly, the
judgment of the Court of Appeals is reversed.
It is so ordered.

himself and his assignees by special contracts brought home to the
purchasers is not a question before us, and upon which we express no
opinion. It is, however, obvious that such a question would arise as a
question of contract, and not as one under the inherent meaning and
effect of the patent laws”).
