Quanta Computer, Inc. v. LG Electronics, Inc.

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 Processing all read requests first ensures speedy access, but may result in the retrieval of outdated data if a read request for a certain piece of data is processed before an outstanding write request for the same data.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 requests until it needs data for which there is an outstanding write request. LG Electronics, Inc. v. Asustek Computer, Inc., No. C 01-02187 CW etc., Order Construing 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 returns 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 multiple devices to share the bus, giving heavy users greater access. This patent describes methods that establish a rotating pri

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 specifications 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 memory 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 purchasers 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 authorized 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 Com

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. 453 F. 3d, at 1370 .

We granted certiorari, 551 U. S. 1187 (2007).

The longstanding doctrine of patent exhaustion provides that the initial authorized sale of a patented item terminates all patent rights to that item. This Court first applied the doctrine in 19th-century cases addressing patent extensions on the Woodworth planing machine. Purchasers 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. McQuewan, 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 machine of the patentee or his assignee,” the Court held, “this purchase carrie[s] with it the right to the use of that machine 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.

destined the article to be finished by the purchaser in conformity to the patent, he has sold his invention so far as it is or may be embodied in that particular 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.

Ill

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 exhaustion 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 transactions involving embodiments of patented methods or processes from

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 infringement. 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 indeed, function at all — until they are combined with memory 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 essentially, even if not completely, embody an invention. Otherwise, patent holders could authorize the sale of computers that are complete with the exception of one minor step — say, inserting the microprocessor

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 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 “independent patents.” Brief for Respondent 13. Finally, LGE argues that Univis does not apply because the Intel Products 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 Replacement 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 “embodied] essential features of [the] patented invention.” 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

lens blanks. Consequently, it appears that appellees perform all of the operations which contribute any claimed element of novelty to Univis lenses.” Brief for United States in United States v. Univis Lens Co., O. T. 1941, No. 855 etc., p. 10 (footnote and citations omitted).

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 etc., pp. 516, 498.

Like the Univis lens blanks, the Intel Products constitute 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 components 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

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” involved 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 Patents 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 principle: 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 embodying patent B, its relationship to patent A does not prevent exhaustion of patent B. For example, if the Univis lens blanks had been

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. Second, 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 “covering] 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 combination 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 combination 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 microprocessor 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 ex

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.” 304 U. S., at 181 . LGE argues that the same principle 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 chipsets 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 Petitioners 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 requiring notice to Quanta appeared only in the Master Agreement, 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

It is so ordered.
