Guest Counterpoint: Patent Exhaustion and Helferich’s Assertion Problem

Guest Post by Professor Amelia Smith Rinehart (University of Utah)

Recently, the Federal Circuit held that the New York Times and others infringed patents claiming methods and systems for delivering content to smartphones.[1] In a related Patently-O essay, Professor Sam Ernst states that the Federal Circuit’s opinion in Helferich is “directly contrary to Supreme Court precedent and represents a fundamental misunderstanding of one of the core purposes of the exhaustion doctrine.”[2] To support his premise, Ernst claims that the Federal Circuit made “a broad and novel pronouncement that patent exhaustion only shields an authorized acquirer from liability, and does not follow the licensed device down the stream of commerce to protect all users of the device for its intended purpose.” [3]

I respectfully disagree. There is nothing broad or novel about the Federal Circuit’s “authorized acquirers” concept. In fact, as the Federal Circuit explains in Helferich, it comports with 150 years of judicial authority examining the patent exhaustion doctrine in a variety of contexts.[4] Likewise, Helferich squares directly with the Supreme Court’s recent exhaustion decisions in Quanta Computer v. LG Electronics[5] and Bowman v. Monsanto Co.[6] More surprising, perhaps, may be the fact that this is so—that Helferich could win infringement suits against New York Times and J.C. Penney based on their provision of content to smartphones that were already licensed by Helferich.[7] Accordingly, the difficulty with Helferich is not that the Federal Circuit stretches the exhaustion doctrine in a new way, but that the doctrine, in its old way, fails to provide an easy way to remove infringement liability in an increasingly complex world of patent assertion.

In his well-reasoned post, Professor Ernst contends that the exhaustion doctrine “has frequently applied to shield from liability persons who are not ‘authorized acquirers’ of the licensed devices,” and looks to both Quanta and the much older Motion Picture Patents v. Universal Manufacturing Co. for support. In my view, neither of these cases provides authority for applying the exhaustion doctrine directly to third parties who have not acquired the sold articles.

Quanta involved a license agreement that authorized the licensee to make, use, and sell the licensed products without restriction. In a separate agreement, the licensee agreed to notify its customers that they did not have a license to combine the licensed products with other non-licensed components. The Supreme Court held that the notice restriction was irrelevant because the licensee had a blanket authorization to make, use, and sell the licensed products. Once made then sold under this first authorization to make, sell, and use, the licensed products could be used by anyone downstream without liability for infringement on the grounds of exhaustion, including those purchasers who had notice of the separate notice restriction.[8] In Quanta, the purchasers of the licensed products—the customers of the licensee, Intel—were authorized acquirers (having acquired title to the products from one authorized to make and sell them unconditionally) shielded from liability when the patent owner sued them for infringement. The Quanta Court did not have to address the question of whether a third party who has not acquired title to a licensed product is shielded from direct liability for its own infringement by an authorized acquirer’s unlimited right to use and sell the patented good obtained via exhaustion.

Motion Picture Patents provides a more nuanced account of the exhaustion doctrine, but still involves authorized acquirers shielded from infringement liability.[9] The patented movie projectors in Motion Picture Patents carried a label notice that restricted the projector owner’s permission to use the projector to use solely with the patent owner’s films. After the patent owner sued a projector owner and a third party film manufacturer for infringement, the Court held that the projector patent rights were not infringed because of exhaustion. The label notice was not enforceable as a matter of patent law because the films were not within the patent rights in question—“to enforce [the label notice] would be to create a monopoly in the manufacture and use of moving picture films, wholly outside of the patent in suit and of the patent law as we have interpreted it.”[10] The projector owner clearly qualified as an authorized acquirer (with an invalid restriction on use) and avoided infringement liability because the authorized projector sale exhausted the patent rights covering those projectors.

Professor Ernst seems to extrapolate from the Motion Picture Patents opinion (which admittedly is unclear on this point) that the third party film manufacturer could not be liable for infringement of the projector patents because it made and sold films for use in the projectors obtained from the patent owner in an authorized sale. In other words, Professor Ernst reads Motion Picture Patents to hold that exhaustion shielded the film manufacturer from liability because otherwise the patent owner could interfere with a projector owner’s use of the machines themselves.[11]

But Motion Picture Patents doesn’t go that far. The questions addressed by the Supreme Court both focus on whether the patent owner can restrict by mere notice a machine’s use by its purchaser or his successors in interest.[12] Later in its opinion, the Supreme Court distinguishes the machine from the materials to be used with it, declaring that “the right of the owner [of the machine] . . . to control by restriction the materials to be used in operating [it] . . . must be a right derived through the general law from the ownership of the property in the machine.”[13] Plainly, the Court applies the exhaustion doctrine to the possessor of the projector, a patented good now in commerce and owned free and clear from the patentee’s right to control the use and sale of the good itself. Therefore, I believe the better view of Motion Picture Patents is that the film manufacturer would’ve been liable, if at all, on a theory of contributory infringement. When the label notices could not be enforced, the sales of the projectors exhausted the projector patent rights as to those machines, and the film manufacturer could produce unpatented film for use in any of the sold machines without contributing to or inducing any infringement by the machine users.

Like the projectors in Motion Picture Patents, goods can travel through many hands downstream from the first authorized acquirer of title to the good. Nothing in Helferich indicates that the Federal Circuit is construing its “authorized acquirer” concept so narrowly as to exclude a good’s future owner (no matter how that downstream party obtained the good) from claiming exhaustion as a defense, should that good’s owner be charged with infringement by use or sale. Rather, the Federal Circuit seems to be unremarkably suggesting that an alleged infringer cannot assert an exhaustion defense unless she has acquired a good from the patent owner (directly or indirectly through someone with authorization to make and sell) that exhausts the claims at issue. Difficult questions may arise as to whether the good was acquired without condition on sale, whether the good’s sale exhausts claims to methods or combinations, whether any post-sale restrictions on the good are enforceable, and so on, but those questions are not at issue in the Helferich appeal.

When Professor Ernst states that “patent exhaustion adheres in the patented device, not in ‘certain persons’ who are authorized to use the device,” he might be conflating the exclusive rights of a patent with the exclusive rights of a purchased good, a conundrum that itself supports the existence of the patent exhaustion doctrine in the first place. Patent exhaustion is a defense to patent infringement. As such, it belongs to juridical persons accused of infringement (people, corporations, etc.), not the good itself.[14] Although we might talk in shorthand about the patented good traveling in commerce unencumbered by patent rights, a patent grants to its owner the right to exclude others (people, corporations, etc.) from infringing the patent. The purchaser of a good holds the rights inherent to the good as a piece of personal property. When the good is patented, these rights overlap. The doctrine of patent exhaustion emerged to reconcile that overlap in favor of the purchaser (and downstream acquirers, too) when it comes to using and selling a patented good acquired from an authorized seller: “one who buys patented articles of manufacture from one authorized to sell them becomes possessed of an absolute property in such articles, unrestricted in time or place.”[15] If the patented good is bought from someone unauthorized, if the transfer of the good’s title is conditional, if the good carries a post-sale restriction, then the purchaser may not be able to avail itself of the exhaustion defense. Thus, it is true that “patent exhaustion removes those legal restrictions [imposed by the patent statute] on certain persons in certain circumstances”[16]

The Federal Circuit makes Helferich look easy (and much less groundbreaking than Professor Ernst suggests) by assuming that Helferich controls separate and distinct patents from an exhaustion standpoint. The court holds that Helferich’s content claims are distinct patentable inventions from its handset claims, and, importantly, the allegedly infringing content providers are distinct infringing entities from the handset owners. This enables the court to affirm that exhaustion does not apply to “multiple related and separately patentable inventions” in this manner, without addressing the possibility offered by Professor Ernst that the exhaustion doctrine’s protection of downstream uses of a purchased good might inure to third parties who practice a claimed invention simply referencing a downstream device.[17]

During the parties’ oral arguments, all three judges asked both sides to consider that more difficult question of whether exhaustion would apply to the third party content providers if the content and handset patents were not separate and distinct. The plaintiffs not surprisingly answered no, that third parties not in possession of the patented good could not benefit from the exhaustion defense. The defendants admitted that no case existed on this point, but that cases like Hewlett Packard and Keurig, Inc. v. Sturm Foods, Inc. held that claims contemplating that an alleged infringer interferes with the use of a patented good would suffice to trigger exhaustion as to that third party.[18] In its opinion, the court confirmed that third party exhaustion was a question of first impression— “[n]either the parties nor we have identified any case from the Supreme Court that has found exhaustion without this common feature [of an authorized acquirer infringing the asserted claims].” Then, distinguishing the Keurig case directly, the court held that an alleged infringer who does not acquire the relevant patented good in an authorized manner cannot claim an exhaustion defense for his own direct infringement.[19]

Professor Ernst concludes that “[a] primary reason why patent exhaustion liberates the patented device from infringement claims is to promote the policy against restraints on alienation.” This notion obviously relates to the restrictions that factored so heavily into the early cases about exhaustion: territorial restrictions, post-sale restrictions, and tying restrictions like the ones in Motion Picture Patents. The holding in Helferich does not, as Professor Ernst urges, “threaten to impose a servitude on devices as they pass down the stream of commerce” because a downstream acquirer of the device can fully avail himself of the defense due to his property rights in the device. Judge Bryson’s walkie-talkie owner can sell his walkie-talkie, use it as an expensive paperweight, or otherwise dispose of it as he sees fit without fear of suit from the patent owner. In contrast, Helferich may continue to bring its infringement claims because these alleged infringers cannot avail themselves of a patent exhaustion doctrine defense. In my view, the Federal Circuit gets it right on the law from Quanta and earlier cases. Indeed, the court recognizes that to hold otherwise would expand the judicial doctrine.[20]

Unfortunately, the exhaustion doctrine presently can’t regulate what is most troubling about Helferich: the patent owner’s licensing practices. Helferich is a patent assertion entity that generates revenue from handset device licensing, making all handset device owners authorized acquirers of its patented goods. Yet, Helferich also intends to generate revenue from content licensing that allows companies like the New York Times, J.C. Penney, CBS, and others to provide content to those same handsets. It cannot do so unless it can threaten these companies with infringement. In this manner, Helferich wields what Justice Clarke in Motion Picture Patents called “a potential power for evil over an industry which must be recognized as an important element in the amusement life of a nation. . .”[21] Like the patent owners in that case, Helferich sells its machines and attempts to prohibit their use with content providers not authorized by Helferich. Unlike the patent owners in that case, Helferich’s content provision claims are independently patentable (or so the Federal Circuit determined based on the limited evidence before it) and, even if they were not, the content providers themselves (who do not use or sell the purchased handset devices) are not subject to the exhaustion doctrine based upon those claims.[22] Confirming the Court’s recent decisions in Quanta and Bowman, the class of “certain persons in certain circumstances” who can avail themselves of the patent exhaustion defense remains bound up in questions of what is used and sold, who bought the things used and sold, and what conditions are placed on that use or sale. None of these relevant limitations are apparent in Helferich.

Nevertheless, Professor Ernst is right to balk at carte blanche enforcement of these patents. The patent exhaustion doctrine fails to eliminate infringement liability for the defendants in Helferich, but the case offers an opportunity for scholars, courts, and other policymakers to reexamine the underlying goals of patenting along with mechanisms within patent law and antitrust law, like the narrowly applied exhaustion doctrine, that may promote or impede those goals in the context of patent assertion entities.[23]

    One point that is in significant tension with the “authorized acquirer” concept as articulated here is the use of the patented article by someone that is not the acquirer but has the permission of the acquirer.

    If I lawfully acquire a patented Keurig coffee machine, the machine is exhausted with respect to my use.

    If a houseguest uses the machine, they are not an “authorized acquirer” — can it really be the case that an infringement action can lie against that houseguest for their use of the machine?

    If I ask my houseguest to make a coffee, am I then at risk of suit for inducing infringement because there is a predicate act of direct infringement when they use the machine?

    While this example is facile, it is trivial to think of instances where it could matter. Assume a fact pattern where a company with a patent on a certain form of server for ecommerce transactions sells (unconditionally and unrestrictedly) computing hardware configured with the server. The purchaser lawfully deploys the server. Are the purchaser’s customers now subject to suit because (depending on how Centillion is applied) they may be found to be “using” the server and are not “authorized acquirers” of the server?

    Does it not seem that the default rule in an unconditional and unrestricted sale, in the absence of burdensome special-purpose licenses, should be to have exhaustion apply to insulate from liability in these cases?

  2. 4

    All in all, this is merely polite hogwash.

    The author assumes his own point without more that there is a “right to balk” and that making money by separately licensing different patents must be “unfortunate” and “most troubling.”

    The intimation of course ASSUMES that those doing so (making money by following the given rules of the game) ARE “Tr011s.”

    Without actually providing a solution, this polite (and well-written from a mechanical sense) piece still suffers from an innate bias and seeming call for the judiciary to take an activist role in reshaping (read that as re-writing) patent law.

    Wrong branch of the government Prof. Rinehart.

    Great article and very well written! Thank you.

    I’ve stated previously that the “real problem” the NYT has is not “exhaustion” (at least not as the law has treated it to date) but the fact that the troll they’re dealing with is asserting junky “content” protecting claims which should never have been granted in the first place.

    Either the exhaustion defense needs to be expanded or the fundamental problem with “content” claims (and similar claims) needs to be recognized and the claims expunged from the system.

    I do take issue with the author’s description of the “increasingly complex world of patent assertion.” That gives way too much credit to the patentees who play these games. The only reason there is the appearance of “complexity” is because some judges took the system off the rails and the PTO effectively ceased examining patents that recited “new” information, “new” logic, or “new” content wrapped up in old computing/communication technology, deciding instead to rubber stamp them.

    1. 3.1

      ^^^ the one-trick pony and the ends justify the means mindset twists the actual situation far from what it actually is.

      Thus, the “solutions” Malcolm offers: warp the exhaustion doctrine beyond what it is supposed to be or deny protection to valid innovation can be seen to be merely a false set of options, necessarily incomplete and merely reflecting a fait accompli of instituting his own philosophy at the expense of the leading area of innovation in today’s world.

      No thank you.

    Frame it how you want, and I don’t care whether or not there’s case law on point. The patentee in these situations shouldn’t be able to license its patents to handset manufacturers and then sue the people who provide the info that the handsets are built to present to their users. If the courts need to invent a new doctrine for that, then they should do so. It would, of course, be better for the sake of appearances if the courts were to do so by saying that this case falls within the bounds of the existing exhaustion doctrine, and if the CAFC doesn’t reverse itself en banc on this one, my guess is we will see yet another smack-down by the Supremes. Worse, by taking the patentee’s side, the CAFC played into the hands of Goodlatte and his donors who want to defang patents.

    1. 2.1


      Q1) Assuming 101/102/103/112 satisfied: Should Gillette be able to patent both its razor blade handle apparatus, and its separate methods and systems of making razor blades that can only be used with its patented handles?

      Q2) If an end user buys a patented Gillette razor blade handle but not the blades, should a third-party razor blade manufacturing company then be able to infringe the Gillette razor blade patents by building factories that implement the infringing systems and methods, and then be free of liability to the extent they can show all of the purchasers of the infringing razor blades own a separately patented Gillette razor blade handle?

      1. 2.1.1

        Nellie, assume the handle is unpatented and you buy patented blades where dependent claims include the otherwise generic handle.

        Do you the user infringe the dependent claims when you make the final assembly of the blades into the handle?

    Morgan Envelope Co. v. Albany Perforated Wrapping Paper Co., 152 U.S. 425, 14 S. Ct. 627, 38 L. Ed. 500 (1894).

    Two devices that work together cooperatively. A set of patents that cover the system and the use of each of the devices separately – but with the cooperation of the other device.

    The Supreme Court held that the authorized acquisition of the one part of the system allowed that acquirer to use the other part of the system provided that it was not independently patented. The holding in Helfrich was premised on the view that there were separate patents on the cell phone parts and on the content provider parts. But this also depended upon the view that there were independent and distinct inventions involved in the two set of patents. The court did not analyze this separately, but relied on the fact that the patent office had not issued double patenting rejections.

    At some point in time, I think the Supreme Court will take this case, and decide that the issue of whether these patents are really independent and distinct must be determined and remand back to lower courts.

    1. 1.1


      In the context only of the system claim, did that case deal with the issue of whether or not a party interacting with one of the devices, is “using” the system? (as in make, use, or sell)

      I’m not talking about satisfying all the elements of a method claim (which likely would require action at both ends) but about a system which exists and infringes (its been made) and wondering whether making it run through its paces by interacting with it at a single point constitutes use.

      1. 1.1.1

        .. and if, by authorized acquisition one party is authorized to use the whole system… what would that have to do with another party (not authorized by acquisition of anything) attempting to use the system?

      2. 1.1.2

        anon, I have only conducted a cursory review of the patents, but on first blush, they seem to cover the very same subject matter, but centric to either the handset or the content provider.

        Now, the Supreme Court has repeatedly held that in situations like this involving whole combinations that the purchaser has the right to use the combination including the right to replace spent parts unless they are separately patented. See, e.g., Aro I. I cannot see the Court holding any differently if a system is involved rather than a combination.

        Thus the whole issue is whether there truly is separate and distinct inventions in the respective patents on the handheld device and content provider patents.

        As I said, on cursory review, I do not see any independent and distinct inventions in the respective patents.


          “very same subject matter”

          How much Gisting involved in this determination? What statutory guidelines are you using?


            Anon, it seems that the point of novelty in the claims is the same regardless of whether the claims are directed to the handset or the content provider. Each set of claims may add conventional features present either in the handset or in the server side. However I did not see very much in the way of novelty in these additional items – but I could be wrong.


              If you apply Diehr faithfully, and take the “Point of Novelty” as the claim as a whole, without Gisting away any of the claim particulars, you would recognize that the separate patents remain separate and that the assumption (nowhere proven) that the patents must cover the same thing (which would then allow the exhaustion doctrine to work as intended) does not reach.

              The legal principle here is clear, and there need not be any squinting or re-writing of patent laws.

              It may well turn out that the additional patents were granted inprovidenty, and that the claims as a whole really do all reach only one invention, but that case has not been made, that judgement not been reached, and by law, we cannot as if yet go there as a conclusory matter – much less so because we may “feel” that such an end is desirable.
