Business Method Patents and the Equitable Standard for Granting Permanent Injunctions: The eBay Case*

By Eric Guttag
January 4, 2013

EDITORIAL NOTE: The decision denying Apple’s permanent injunction was recently followed by the CAFC decision in Presidio that tilts the pendulum back toward the awarding of permanent injunctions when competitors are involved. Eric Guttag and I have communicated via e-mail about permanent injunctions. Guttag wrote the following article in 2006. I asked if I could republish it here and he agreed. Here is Guttag’s take on eBay v. MerchExchange.

Justice Clarence Thomas delivered the opinion of a unanimous Supreme Court in eBay v. MerchExchange in 2006.

Once upon a time, the view was that “methods of doing business” could not be patented.  That view changed forever with the 1998 case of State Street Bank & Trust Company v. Signature Financial Group Inc. [i]  In State Street, the Court of Appeals for the Federal Circuit (Federal Circuit) held there was no “business method” exception to patentability:  “Whether the [patent] claims are directed to subject matter within § 101 [ii] should not turn on whether the claimed subject matter does “business” instead of something else. [iii]

In certain quarters, the grant of patents on “business methods” has been increasingly viewed with alarm and concern.  One concern is that the holder of such patents could permanently enjoin such infringement, thus potentially increasing the bargaining position of the “business method” patent holder.  That concern is very real.  For example, in the “non-business method” patent context, the Federal Circuit held in the 1989 case of Richardson v. Suzuki Motor Company that, in view of the recognized “right to exclude” under the patent, “the general rule [is] that an injunction will issue when infringement has been adjudged, absent a sound reason for denying it.” [iv]

The standard for granting permanent injunctions for patent infringement generally, and “business method” patents specifically, became the focus of eBay, Inc. v. MercExchange L.L.C. [v]  The eBay case involved a patent owned by MercExchange which covered a system for selling goods through an electronic network of consignment stores.  While upholding a jury verdict that this patent was infringed by eBay and others, the Eastern District of Virginia in eBay refused to grant a permanent injunction against such infringement.  One reason expressed for denying the permanent injunction:  “a growing concern over the issuance of business-method patents.” [vi]

On appeal, the Federal Circuit ruled that the Eastern District of Virginia had improperly denied the permanent injunction.  Instead, the Federal Circuit, relying on the “general rule” of the Richardson case, held that such an injunction would usually issue “once infringement and validity have been adjudged.”  As the Federal Circuit saw it, “a general concern regarding business-method patents” was “not the type of important public need that justifies the unusual step of denying injunctive relief.” [vii]  The Federal Circuit further held that the other three concerns expressed by the Eastern District of Virginia for denying the permanent injunction (i.e., contentious litigation, MercExchange’s willingness to license the patent, and the failure to request a preliminary injunction) were also not persuasive for denying the permanent injunction.

Justice Thomas delivered the opinion of the Supreme Court in unanimously vacating the Federal Circuit’s ruling on the appropriate standard for granting a permanent injunction for patent infringement. [viii]  As stated by Justice Thomas, the traditional “four-factor” equitable test for granting a permanent injunction equally applied to cases of patent infringement:  (1) irreparable harm to the plaintiff (i.e., MercExchange); (2) legal remedies, such as damages, were inadequate to compensate the plaintiff for its injury; (3) a remedy in equity (i.e., injunction) was warranted by the “balance of hardships” between the parties (i.e., MercExchange and eBay et al.); and (4) the public interest would not be disserved by the permanent injunction.  In fact, Justice Thomas further relied on Section 283 of the Patent Act [ix] as recognizing that injunctions “may issue” in patent infringement actions in accordance with the principles of equity (i.e., the traditional “four-factor test”).

Justice Thomas also found that, like the Federal Circuit, the Eastern District of Virginia had not “fairly applied these traditional equitable principles in deciding” the request for permanent injunction.  While the Eastern District of Virginia recited the traditional “four-factor” test, Justice Thomas said the Eastern District of Virginia erred in adopting “expansive principles suggesting that injunctive relief could not issue in a broad swath of cases,” including those where the patent holder offered to license the patent or did not practice the patented invention.  In addition, Justice Thomas was aware of the tension created by the Eastern District of Virginia’s “categorical rule” relative to the Supreme Court’s 1908 decision in Continental Paper Bag Company v. Eastern Paper Bag Company. [x]  In Continental Paper Bag, the Supreme Court had rejected the “categorical” proposition that “a court of equity has no jurisdiction to grant injunctive relief to a patent holder who has unreasonably declined to use” the patented invention. [xi]

In contrast, the Justice Thomas found that the Federal Court had go awry in the “opposite direction” by articulating a “general rule” on granting equitable relief that was “unique to patent disputes.”  Just as the Eastern District of Virginia was wrong in “its categorical denial of injunctive relief,” the Federal Circuit “erred in its categorical grant of such relief.”  Instead, Justice Thomas held that “the decision whether to grant or deny injunctive relief rests within the equitable discretion of the district courts, and that such discretion must be exercised consistent with the traditional principles of equity, in such patent disputes no less than other cases governed by such standards.” [xii]

Chief Justice Roberts’ concurring opinion was both brief and obtuse.  While agreeing with Justice Thomas’ ruling that the traditional “four-factor” test for injunctive relief also applied to patent disputes, Chief Justice Roberts’ concurring opinion then made a nebulous reference to “a difference between exercising equitable discretion pursuant to the established four-factor test and writing on an entirely clean slate.”  It would have been helpful if Chief Justice Roberts had spelled out exactly what was “written” on that “slate,” but nothing in his concurring opinion clearly does this. [xiii]

The concurring opinion of Justice Kennedy is even more unfortunate.  Like Chief Justice Roberts, while agreeing with Justice Thomas’ holding that the traditional “four-factor” test applied to the grant of injunctive relief in patent cases, Justice Kennedy’s concurring opinion went even further to suggest that “trial courts should bear in mind that in many instances the nature of the patent being enforced and the economic function of the patent holder present considerations quite unlike earlier patent cases.”  As Justice Kennedy saw it, “an injunction, and the potentially serious sanctions arising from its violation, can be employed as a bargaining tool to charge exorbitant fees to companies that seek to buy licenses to practice the patent.”  What is particularly distressing about Justice Kennedy’s concurring opinion is the further comments he makes about injunctive relief in the context of patents on “business methods”:

[I]njunctive relief may have different consequences for the burgeoning number of patents over business methods, which were not of much economic and legal significance in earlier times.  The potential vagueness and suspect validity of some of these patents may affect the calculus under the four-factor test.”  (Emphasis added.)

Why Justice Kennedy felt compelled to make these unfortunate remarks (especially those italicized) about applying the traditional “four-factor test” to patent cases generally and “business method” patents specifically is anybody’s guess.  No citation is made by Justice Kennedy to the record, other facts or even case law to support these remarks.  These remarks are not only completely unnecessary, but completely inconsistent with the holding in the eBay case that there is nothing “unique” about applying the traditional “four-factor test” to patent disputes.  One can only hope that these regrettable remarks will be ignored as the dicta they are. [xiv]  If not, these remarks may be cast unfortunate, as well as erroneous, doubt on the validity of many patents characterized (rightly or wrongly) as involving “business methods.”

Franklin Capital Corp., 546 U.S. ___, ____ (2005)); and (2) “When it comes to discerning and applying those standards, in this area as others, ‘a page of history is worth a volume of logic’” (citing the opinion of Justice Holmes in New York Trust Co. v.

[xiv] These unfortunate remarks in Justice Kennedy’s concurring opinion in the eBay case may already be causing mischief with regard to the grant of permanent injunctions in patent infringement disputes.  In the recent case of z4 Technologies, Inc. v. Microsoft Corp.,  F.Supp.2d  (E.D. Tex. 2006), the District Court for the Eastern District of Texas denied a motion for entry of a permanent injunction after two patents were determined by a jury to be willfully infringed.  In considering the second factor (adequacy of remedies available at law), the Eastern District of Texas noted that Justice Kennedy in eBay had “instructed courts to be cognizant of the nature of the patent being enforced and the economic function of the patent holder when applying the equitable factors.”  See z4 Technologies, supra, slip opinion at page 6.  Whether the Federal Circuit will accept this assessment by the Eastern District of Texas if the z4 Technologies case is appealed remains to be seen.

    Justice Kennedy’s language about vagueness and suspect validity is not helpful. At the point that a district court judge is deciding whether to grant an injunction in a patent case, the fact finder (either judge or jury) has already determined that: (1) an accused product infringes a claim of the patent; and (2) the claim has not been proved to be invalid (burden of proof on the accused infringer). At this stage any possible vagueness and suspect validity has already been decided in the patentee’s favor.

    Thus these factors should never be used against the patentee in deciding to whether to grant an injunction.

    Interesting analyses of the case, presumably shortly after The Decision? It seems once again the SCOTUS was basically legislating from the bench, effectively subverting what Congress had intended the law to be with apparently no real justification in a legal sense as far as I can gather, now that I know a little more about the case.

    To use a somewhat fanciful analogy, let’s suppose the Supreme hunter goes in search of Big game, and finds a herd of elephants. He then spots the legendary white elephant (business methods), and wasting no time, he takes careful aim and shoots, bringing down said elephant abruptly. What he didn’t consider though (or maybe he did), is that he took down the whole herd with a single shot as well.

    It seems to me as if Congress didn’t give them license to take down more than one beast at a time. It amounts to the taking of a pretty important part of the underlying IP rights of all, rendering patents a lot less valuable, especially for smaller entities.

    This comment is from EG, who has been having some difficulty posting it. He asked me to post it for him…

    My last paragraph is “prophetic” about the mischief caused by Kennedy’s “inane” concurring opinion which is internally inconsistent with Thomas’ opinion of the court that says the principles of equity for injunctions should apply equally in all cases. Why isn’t that “principle” also true for applying permanent injunctions to infringed “business method” patents? What’s even worse is that several of the district court’s have justified the refusal to issue permanent injunctions to “non-producing entities” (NPEs) squarely base on Kennedy’s “inane” concurring opinion. Since when does a “plurality” concurring opinion take precedence over the opinion of the Court which what the majority of SCOTUS Justices agreed with.

    What might surprise some of you is who I believe is the most “pro-patent” Justice: Clarence Thomas. Why do I say that? Well, he wrote the majority opinion in J.E.M AG Supply v. Pioneer Hi-Bred International (holding that sexually reproduced plants were patent-eligible under 35 USC 101) and Kappos v Hyatt (no limitation on introducing new evidence in 145 proceeding). As far as eBay goes, Thomas’ the Opinion of the Court is far more “balanced” and understandable compared to the Chief Justice’s “obtuse” concurring opinion and Kennedy’s nonsensical and logically inconsistent concurring opinion. If you read Thomas’ opinion carefully, it’s clear he did his “legal homework,” including interpreting the “discretionary” language of 35 USC 283 quite reasonably, and even recognizing the Supreme Court’s 1908 ruling in Continental Paper Bag case that rejected the “categorical denial” of injunctions to NPEs that Kennedy’s bizarre concurring opinion would seem to embrace.

    Also, Thomas’s dissenting opinion in MedImmune seriously challenged the logic of Scalia’s majority opinion, which is saying something, given that Thomas and Scalia are usually considered to be on the same “ideological” page. Scalia’s Neanderthal reasoning in MedImmune is completely divorced from the reality of what goes on in patent licensing negotiations, and basically puts the patentee/licensor at a huge negotiating disadvantage relative to the licensee/prospective licensee. Under MedImmune, all the patentee/licensor has to do is resist what appear unreasonable overtures from the licensee/prospective licensee to be at potential risk of that licensee/prospective licensee running off to court to file a DJ action, crying “foul,” alleging that the patentee/licensor isn’t playing “nice,” and is about to drag them into court for patent infringement. In other words, MedImmune has made the threat of DJ actions a “billy club” for the licensee/prospective licensee to wave at the patentee/licensor.

    The worst Justices when it comes to patent law are Breyer, Scalia, and Roberts in that order. Breyer is an anti-patent “ideologue,” as bad as Justice Douglas; Breyer’s opinion in Mayo is a travesty which can’t be squared with the prior Diamond v. Diehr case (claimed subject matter is to considered “as a whole” under 35 USC 101) no matter what Breyer said. Scalia has a “19th Century” mentality when it comes to what is patent-eligible under 35 USC 101 (as Bilski shows, he’s definitely against “business methods” being patent-eligible, but understands the implications of 35 USC 273 in that regard, unlike retired Justice Stevens who disingenuously argued that this provision was a “red herring”). For allegedly being fairly sharp, from the oral argument transcript in Bilski, the Chief Justice shows amazing befuddlement on understanding the difference between patent-eligibility under 35 USC 101 and patentability under 35 USC 102/103.

    When it comes to patent law issues, Thomas is the only SCOTUS Justice I respect. His other 8 generally anti-patent “cohorts” I do not.

    Thanks for the comment. The problem as I note in my comment above is not with Thomas’ Opinion of Court; Thomas’ reasoning is grounded solidly on what 35 USC 283 (patent injunction statute) says. While we might like the Federal Circuit’s view that injunctions should generally issue where there’s patent infringement, that’s not what 35 USC 283 says or commands courts to do.

    My problem is with Kennedy’s concurring opinion which, as I point out, several district court’s have unfortunately latched onto. In targeting a class of patents (“business method” patents), Kenendy’s concurring opinion is completely inconsistent with Thomas’ reasoning that the “principles of equity” for applying injunctions is the same for patent cases as it is for other cases. That being true, there should be no “suspect class” of subject matter that get’s treated differently when determining whether or not a permanent injunction should issue. Even worse, as I point out in my eBay article, Kennedy’s concurring opinion points to no evidence in the record or anywhere else for treating “business method” patents differently and is classical SCOTUS rhetorical nonsense that I’ve grown to despise.
