On November 27, 2017, the United States Supreme Court heard oral argument in Oil States Energy Services, LLC v. Greene’s Energy Group, LLC  on the thorny question of whether the inter partes review (IPR) provisions of the America Invents Act  (AIA) run afoul of constitutional guarantees on three related issues: separation of powers; the doctrine of unconstitutional conditions (i.e. whether Congress can condition the grant of a patent on an applicant agreeing to waive his or her Seventh Amendment right to a jury trial); and the due process clause of the Fifth Amendment. The conventional wisdom is that the Court is likely to affirm the decision below (perhaps with dissents from Justices Roberts, Alito, and Gorsuch) and allow the Patent and Trademark Appeal Board (PTAB) to continue its current form.  Nevertheless, the oral arguments in the case expose the deep and pervasive misconceptions as to the both the desirability and constitutionality of the AIA and IPR.

It is important to examine four related questions as we consider the oral arguments and what they suggest about the constitutional issues at stake in the case. First, when, if ever, does the PTAB lose its ability to claim jurisdiction over a case bought by a patent holder against an alleged infringer after the Patent and Trademark Office (PTO) grants the patent? Second, can the PTAB condition a grant of a patent on the patentee’s agreement that it retains control over future litigation over the validity of that patent, even in suits that the patent holder brings in federal district court? Third, is it consistent with due process for Chief Judge David Ruschke of the PTAB to add judges (especially himself and the Vice Chief Judge Scott Boalick) to any ongoing patent panel in order to promote uniformity in the issuance of patents—a power that PTAB has been explicitly claimed?  Fourth, should any state be forced to submit to jurisdiction before the PTAB if a potential infringer chooses to ask for IPR before the PTAB? Unfortunately, the questions from the Justices and the responses given to them by the lawyers raise troublesome questions that do not admit of easy answers. 

I.    Patent Grants and the Timing of Inter Partes Review. 

The first challenge directed to Allyson Ho, counsel for Oil States, was aggressively stated by Justice Ruth Bader Ginsburg: “there must be some means by which the Patent Office can correct the errors that it’s made, like missing prior art that would be preclusive.” (Tr. 3-4). Justice Kagan quickly chimed in by asking, as if the question had no real answer, where it is best to “draw the line” between those cases where traditional judicial procedures are required and the procedures to the PTO are both appropriate and efficient.. (Tr. 17). Ho’s answer was that “trial-like” procedures cannot be upended through truncated procedures before the PTAB. (Tr. 19).

I would answer the questions posed by Justices Ginsburg and Kagan in a somewhat different manner. To Justice Kagan’s query on where to draw the line, the best answer is the same that it has always been: the patent office loses control over the patent once it is finally issued, so IPR-like procedures are only appropriate until issues, after which all subsequent disputes must be resolved in court. That line is clear, sensible and known to all. Any line at some later date will be an exercise in arbitrary decision making. On this point, Justice Breyer sounded a sensible note of caution when he asked whether the IPR could be triggered some ten years after the patent was granted after the company had spent some $40 billion in reliance on the grant. (Tr. 29). If the PTO always needs breathing room to correct its prior mistakes, the passage of time becomes a mere detail that warrants no further consideration—a novel approach that would reduce the venerable statute of limitations to an inconvenient obstacle that could be shunted aside in the endless pursuit of perfect justice.

In fact, there is no good answer to Justice Kagan’s question unless one follows the pre-AIA precedents, which draw the proper line at the time the grant of the patent becomes final.  The relevant line of cases starts with the 1864 Supreme Court case of United States v. Stone,  which arose from a boundary dispute between the United States and David Brian Stone, who had taken his title by assignment from the Delaware Tribe. The Supreme Court observed, “to proceed rightly, the United States filed a bill in the Federal Court of Kansas, against the Indian chiefs and Stone, to have them judicially decreed null, and the instruments themselves delivered up for cancellation.”  The use of the phrase “to proceed rightly” carries with it the clear implication that the government would have proceeded incorrectly if it had used its own administrative processes to resolve the dispute. To be sure, the patent in Stone involved land and not an invention, but there is no coherent reason why grants of land should be treated differently from grants of patents—any more than grants of patents should be treated differently from those of copyright. The obvious response to Justice Kagan’s question is that the line belongs where it has always been placed—at the point that the grant becomes final.

Other authorities come out in the same direction. Benjamin Christoff summarizes the relevant cases as follows: 

In McCormick Harvesting Machine Co. v. Aultman [169 U.S. 606 (1898)], the Supreme Court described in no uncertain terms the limitations on the PTO's authority: “It has been settled by repeated decisions of this court that when a patent has [been granted] . . . it has passed beyond the control and jurisdiction of that office, and is not subject to be revoked or canceled by the president, or any other officer of the government.”  After issuance, the patent “has become the property of the patentee, and as such is entitled to the same legal protection as other property.”  The Court later reiterated this view in Crown Cork & Seal Co. v. Ferdinand Gutmann Co. [304 U.S. 159 (1938)]: “After a patent is granted it passes ‘beyond the control and jurisdiction’ of the Patent Office; the proceedings are closed and the application can neither be amended nor serve as the basis for a new ‘divisional’ or ‘continuing’ application. ”  

Using the time of the completed conveyance to determine when any grant vests supplies a uniform theory for all government grants that is easily identifiable and enforceable. It also prevents the needless proliferation of different rules for different asset classes, and it prevents the systematic encroachment by Congress and the administrative state on the prerogatives of the judicial branch. Against these virtues of tradition and clarity, the PTO argued that the new procedures boast efficiency, costs savings, PTO expertise in adjudication, and the gains to investor confidence.  These purported justifications for allowing a PTAB review of issued patents all fail.

On the first question of efficiency, the correct inquiry starts with a comparative analysis of how the PTO will work under the two alternative legal regimes. According to the conventional wisdom, the power to first revisit and then revise patents under the AIA is intended to "improve patent quality and restore confidence in the presumption of validity that comes with issued patents” because that review "screen[s] out bad patents while bolstering valid ones."  There is no empirical evidence on the strength of a novel procedure, so this claim rests on theory. But even economic theory offers no support for the proposition that the AIA procedure reduces both kinds of error—allowing bad patents and denying good ones.  The key insight here is that the PTO is far more likely to take care in its initial examinations of patents if it understands that, once it grants a patent, its powers of review are over. This observation is not inconsistent with the view that some pre-grant procedure should allow challengers to come forward before any patent issues. The anticipated quality of the patent should be higher if the initial review is done expeditiously. The more thorough review at the first stage reduces the need for adjudication after that grant is made, which in turn lowers the level of system-wide uncertainty. The more expeditious process therefore cuts down on the cost of subsequent deliberations. The expertise of the PTO is respected, which is why the law creates a presumption in favor of patent validity.  There is little reason to think that anybody, the PTO included, will show greater expertise the second time it takes a case, especially if the PTO can stack the IPR panel. Given the widespread distrust of the PTAB, why expect that the IPR will restore or enhance inventor confidence? Small inventors were the strongest opponents of IPR because they feared being bulldozed by large corporations who could now drag them and their assignees before the PTO. 

Investor confidence will be decreased—not increased, as PTO supporters claim—by a distinctive feature of the PTO that allows the PTO to continue with the IPR even after the private dispute between the patent holder and the alleged infringer has been settled. (Tr. 7).  IPR thus places the patent holder in the difficult position of having two opponents instead of one. The PTAB readily strikes down patents on grounds of patent eligibility or prior art. The credible threat to institute an IPR before the hostile PTAB is likely to induce the patentee to settle the case on terms favorable to the challenger before it is brought back to the PTO, which can still seek to invalidate the patent, thereby affording umbrella protection against all potential infringers. This extraordinary feature is not found in ordinary trials, which supplies yet another reason the PTAB should not be given the unprecedented power that fuses administration and adjudication without the protections that attend real federal court disputes.

II.    Unconstitutional Conditions

The ability to grant or deny a patent lies within the exclusive province of the PTO. Its legal monopoly in this area should trigger the application of the standard limitations that apply to any legal monopoly. It must be prevented from abusing its monopoly power so that all of the restrictions that it imposes on patentees (like all other monopoly impositions) are consistent with the general objective of advancing overall social welfare. That conclusion follows from a proposition announced by Sir Matthew Hale, who said of wharves over which a private party had a Crown-bestowed monopoly that they were “affected with the publick interest” and thus subject to a limitation that “all tolls be reasonable.” Accordingly, those rates had to be high enough to cover expenses and allow an appropriate profit, not set so low as to constitute confiscatory regulation,.  Private parties are not the only parties that possess monopoly power, and when they do, it is typically because they have received an exclusive franchise from the state. The duties of fair and reasonable service should attach to any government-run or government-granted monopoly in the same way they attach to private monopolies. The same kinds of duties and limitations should be imposed on the patent office when it grants patents as are imposed on the state when it grants a similar power to a railroad or a public utility party. And that calls for correlative duties to prevent the abuse of state monopoly power.

Hence, it was perfectly appropriate for Chief Justice Roberts to ask the lawyers for Greene’s Energy and the Solicitor General whether they thought that Oil States, as a patentee, was under a duty to take the “bitter with the sweet.” (Tr. 32). The answer from Mr. Kise for Greene’s Energy was that “the scheme was set up so that these rights are taken subject to the power of Congress to determine patentability.” (Tr. 32). When the question was repeated by Justice Gorsuch, Mr. Stewart for the government doubled down by insisting (in a fragmented exchange that no patentee could have formed “any expectation” that it could not be bound by any condition that the Congress attached to the grant, including those which forced adjudication of patent disputes before the PTAB (Tr. 43). 

It should be evident that these assertions of absolute congressional power ignore the limitations that the doctrine of unconstitutional conditions imposes on Congress. That doctrine is always in play when the state exercises its monopoly power to make various kinds of grants. “Stated in its canonical form, this doctrine holds that even if a state has absolute discretion to grant or deny any individual a privilege or benefit, it cannot grant that privilege [or benefit] subject to conditions that improperly ‘coerce,’ ‘pressure,’ or ‘induce’ the waiver of that person’s constitutional rights.”  At an abstract level, this doctrine sounds arcane and obscure, but a simple example shows how it works. The government has a monopoly over the public highways. It can condition the ability to drive on taking tests for driver safety, or on the willingness to take automobile insurance. But it is surely unconstitutional for the government to insist that, in order to drive, you sign loyalty oaths, waive your Fourth Amendment rights against unreasonable searches and seizures, or take out a life insurance policy for the benefit of the state. The first set of conditions are those that advance the overall efficiency of operations along the highway. The second set of conditions are illicit efforts to transfer wealth from a weaker to a stronger political party, which is the essence of the political abuse associated with monopoly power.

The earliest cases involving the application of the doctrine of unconstitutional conditions were tied to a vital question of federal jurisdiction: the right of any individual or firm to avail itself of federal diversity jurisdiction, by bringing (as a plaintiff) a suit in federal court against the citizen of another state, or by removing (as a defendant) a case into federal court when sued by a defendant of a different state. The federal government can, of course, place some limitations on diversity jurisdiction, including minimum rights of suit or the exclusion of certain categories of cases. But it is a different kettle of fish to require a foreign corporation that seeks to do business in the state to forfeit all access to federal courts under diversity jurisdiction. Such a requirement was struck down in two early Supreme Court cases that are unquestioned today: Insurance Co. v. Morse  and Terral v. Burke Construction Co.  These decisions were quite emphatic in denying the power of any given state to tie permission to do business in the state with the forfeiture of access to federal courts under diversity jurisdiction. In Morse, Justice Hunt wrote: 

Every citizen is entitled to resort to all the courts of the country, and to invoke the protection which all the laws or all those courts may afford him. A man may not barter away his life or his freedom, or his substantial rights. . . . In these aspects any citizen may no doubt waive the rights to which he may be entitled. He cannot, however, bind himself in advance by an agreement, which may be specifically enforced, thus to forfeit his rights at all times and on all occasions, whenever the case may be presented.  

And in Terral, Chief Justice Taft followed suit by writing: 

[A] State may not, in imposing conditions upon the privilege of a foreign corporation's doing business in the State, exact from it a waiver of the exercise of its constitutional right to resort to the federal courts, or thereafter withdraw the privilege of doing business because of its exercise of such right, whether waived in advance or not. 

Any principled defense of freedom of contract is always subject to reasonable limitations when a state or a private party exercises monopoly power. In this instance, the Framers of the Constitution thought that access to diversity jurisdiction was sufficiently important to build its protection into the Constitution. The states cannot undermine that structural arrangement by conditioning the access of foreign corporations to the state on waiving that constitutionally protected option. If such a condition were allowed, most firms would waive the benefit of diversity jurisdiction, for the loss of access to federal courts in some future litigation is a small price to pay for the opportunity to do business in another state. But then every state would demand that concession and virtually every corporation would accede, all of which would amount to an implicit removal of the structural protection of diversity jurisdiction. Avoiding just this debacle is why the unconstitutional conditions doctrine retains its great tenacity.

Contrary to the remarks of the lawyers Kise and Stewart, this doctrine also applies to the congressional power over patents. No inventor can afford to refuse to take a patent because its grant is conditioned on the waiver of various constitutional rights to adjudication, complete with jury trials, in an Article III court. The same analysis of unconstitutional conditions applies to the fundamental right to have a case heard before a neutral tribunal, in which questions of fact raised in suits at common law must be tried before a jury under the Seventh Amendment. The only way for the government to resist the application of the unconstitutional conditions doctrine is to insist that there is no independent constitutional right to a jury trial in patent cases, even if corporations enjoy the benefits of diversity jurisdiction. In addition, the protections provided by due process are nugatory if a party can be forced to litigate before a panel that can be stacked by a single judge to ensure a particular point of view. Finally, the right to a jury trial at common law cannot be deprived by putting the matter before a tribunal—it is not appropriate to call it a court—whose Chief Judge can add new members to a panel at any given time.

It is of course possible to deny that the right to a jury trial exists in patent cases, as Mark Lemley has recently done in his article Why Do Juries Decide if Patents are Valid?  But H. Tomás Gómez-Arostegui and Sean Bottomley have shown in their amicus curiae brief  that Lemley’s historical account is riddled with errors, because in fact courts of equity routinely sent cases to the law courts for final disposition in which all questions of fact were resolved by juries. After an exhaustive study, they conclude that:

The cases demonstrate that juries regularly decided the following issues related to validity: 

  1. whether the invention was new; 
  2. whether the patentee was the actual inventor of the purported invention; 
  3. whether the invention was useful; 
  4. whether the specification accurately described the claimed invention; and 
  5. whether the specification enabled a person working in the relevant art to construct the item described in it. 

The question of patent eligibility is not clearly included in that list, but it is just that determination that has to be made to hold that something is an invention, as opposed to either an idea or a product of nature. The question of patent validity was not a mix between legal and equitable considerations inconsistent with the general rules on the relationship between the two side of the courts, contrary to what Lemley argues. In oral argument, Justice Sotomayor, citing the brief of Gómez-Arostegui and Bottomley, made much of the position of the English Privy Council, which had long operated chiefly as an advisory body to the Crown, but which often served as the appellate court of last resort for legal disputes that arose in the colonies or former colonies. Although its influence had “waned,” Sotomayor insisted, that it had not been “eliminated, and it didn’t mean that the Privy Council or the crown thought that it [sic] no longer had those rights.” (Tr. 25-26). But as Gómez-Arostegui and Bottomley make clear, even the fading jurisdiction of the Privy Council never reached the issues set out above. They first state explicitly that the role of the Privy Council had been “inadvertently overstated” by many scholars who had not looked at the full range of available sources. More to the point, they noted: “As a forum to adjudicate infringement, the Council played essentially no role after the Restoration [i.e. 1660], with enforcement instead falling to the Chancery, King’s Bench, Common Pleas, and Exchequer.”  

To be sure, the Privy Council retained a rarely used process that was much more cumbersome than the truncated AIA processes at issue in Oil States. In the Privy Council, no one person could decide the issue. The initial petition was first referred to a committee that in turn delegated the matter to the Attorney General, who used affidavits and testimony to examine the petition, after which it could be voided only with the concurrence of six other members of the Privy Council. The entire process included many veto points on the road to invalidation. It would be odd to treat this rare and complex process as the decisive precedent to legitimate the invalidation process that the AIA virtually vests in a single person. It is clear that the accurate guide in this case is the Statute of Monopolies which made it clear that “the force and validity of [patents], and every of them, ought to be, and shall be for ever hereafter examined, heard, tried, and determined, by and according to the common laws of this realm, and not otherwise.”  

III.    Deprivations of due process 

The third major concern raised in Oil States is whether the right of the Chief Judge of the PTAB to add new members to a panel during the course of a hearing comports with the notions of due process that demand a hearing before a neutral and informed judge.  The issue of panel assignments is important in all appellate courts, and a recent article by Professor Marin K. Levy offered an exhaustive review of these practices in the federal courts of appeals.  The premise of her study is that most circuit courts announce that they make random assignments of judges to individual cases. The obvious justification for this practice is that it prevents any effort to stack a panel with judges who are inclined to a given point of view. Levy summarizes her position as follows: “Although the courts generally tried to ‘mix up’ the judges, the chief judges and clerks responsible for setting the calendar also took into account various other factors, from collegiality, to efficiency-based considerations.” At no point does Levy’s study make any reference to a process whereby the chief judge of a circuit can stack the tribunal with persons whose views are sympathetic to his or her own. The notion of due process—which traditionally involves a trial before a neutral panel under fixed and determinate rules—is mocked when the PTAB is allowed to stack a panel with sympathetic judges, contrary to the practice of every other court. 

Before the Supreme Court, both Kise and Stewart downplayed the importance of this extraordinary power. Mr. Kise said that “I don’t believe that’s taken place more than one or two times.” (Tr. 33-34). He was cut off before he could say that he did not think it took place here, but then in response to Justice Kennedy’s question said, “if it were rampant, then I think what the Court said in Cuozzo  . . . that the Administrative Procedures Act and other provisions of the Constitution would deal with infirmities in a particular case on an as-applied basis.” (Tr. 33-34). The matter was then left hanging until, in response to a question by Chief Justice Roberts—“Does it comport with due process to change the composition of an adjudicatory body halfway through the proceeding? (Tr. 45)—Mr. Stewart offered this response: “This has been done on three occasions. It has been done at the institution stage,” (Tr. 45) i.e. at the outset of the case and not in the middle. This exchange understates the seriousness of the problem. If the issue were indeed one that should be resolved on an “as-applied basis,” the due process challenge should succeed in all such cases, unless some argument could be put forward to explain that the practice makes sense in some cases, but not in others. But there is no hint anywhere as to what the relevant criteria for carving out this exception should be. Nor, as a matter of fact, does it appear that these events are as infrequent as was claimed, for were at the time of oral argument many pointed charges of improper conduct.  

In a deeper sense, however, the frequency of use should not matter, because it turns out that David Ruschke, Chief Judge of the PTAB, has made panel stacking official policy:

The PTAB’s chief judge noted that there are four instances in which the agency’s standard procedures give him the authority to expand a panel on a validity trial: when the trial involves an issue of exceptional importance; to maintain uniformity of PTAB decisions; when the USPTO Director submits a written request on an issue of first impression; or when the director feels that the panel should not follow a previous board decision to better serve the public interest. 

However, Ruschke noted that his authority to expand the panels for PTAB trials doesn’t require him to notify the parties in the trial that the decision to expand the panel has been made. . . . 

“I’ve only expanded [the panel] in situations where I’ve added [Vice Chief Judge] Scott [Boalick] and myself to emphasize a unanimous decision below,” Ruschke stated. 

The astounding assertion of power was made on November 16, 2017, eleven days before the oral argument in Oil States, in an executive session held to plan future PTAB policy. Ruschke publicly stated that position two days after the oral argument in which Kise and Stewart made apparently inconsistent representations. This is no longer a matter of speculation, for on December 19, 2017, the PTAB in Ericsson Inc. v. University of Pennsylvania  announced in a judgment in which both Ruschke and Boalik sat that “our standard operating procedures provide the Chief Judge with discretion to include more than three judges,” claiming that this power was delegated expressly to the Chief Judge by the legislation under In re Alappat.  

But the precise question in Alappat was this: “When a three-member panel of the Board has rendered its decision, does the Commissioner have the authority to constitute a new panel for purposes of reconsideration?”  The case does not mention any power to reconsider if the initial panel has not rendered its final judgment on the issue. And the difference is palpable, for under the procedure sanctioned in Alappat, any reviewing court gets to read two opinions which come to different conclusions. Nor does Ericsson comment on the possible reasons for allowing a second panel to reconsider a case. The point is uncertain, but Alappat reads like a provision calling for an en banc hearing that allows for a broader range of views, not for the particular programmatic agenda of the Chief Judge. And even if Alappat is read that broadly, its decision is not binding on the Supreme Court. At the very least, Ericsson only magnifies the uneasiness about PTAB procedures, because its decision was announced after oral argument in Oil States. The Supreme Court should be apprised of this development by all or some of the parties before it is asked to render its final decision. 

PTAB’s public statement of principle flouts due process requirements. The four stated reasons for expanding panels are themselves good reasons not to allow the Chief Judge to tamper with panel composition, let alone make himself the decisive voice on the case. Irregularities of procedure are least welcome in cases of “exceptional importance.” It is precisely in these cases that no one person should be allowed to wield inordinate influence. More specifically, unlike en banc hearings, which are intended to collect a wide range of disparate views, this procedure involves the Chief Judge secretly appointing only himself and the Vice Chief Judge to panels for the express purpose of rigging the outcome in favor of the legal positions that these two judges favor. Placing such inordinate power in the hands of one or two individuals is an open admission of prejudice that should never be allowed in any tribunal, whether judicial or administrative. It is the sign of a broken culture that public officials should trumpet their own misconduct as a form of public virtue.

IV.    Substantive Issues in the PTAB: Of claim construction and sovereign immunity 

The PTAB’s control extends to a full range of procedural and substantive issues. It is far from clear that the PTAB should have dispositive power in many of these areas, given that its decisions tend always to strengthen its dominant ethos that strong patent rights are a mistake. Michelle Lee was the Director of the PTO when Cuozzo Speed Technologies, LLC v. Lee was decided;  she joined the agency after her tour of duty with Google, which is known for its general anti-patent positions. Up for decision in that case were two issues: appeal and claim construction.

The initial question was the PTO Director’s decision "whether to institute an inter partes review under this section shall be final and non-appealable”;  the Supreme Court answered this question in the affirmative, given the clear language of the statute. The second question was whether the authority delegated to the PTO under the AIA to issue regulations “governing inter partes” is broad enough to uphold a PTO regulation that provided that in the course of IPR any patent claim “shall be given its broadest reasonable construction in light of the specification of the patent in which it appears.”  The standard judicial rule calls for the “ordinary meaning” test to apply.

A.    Appealability 

On the first of these rulings, it is generally the case that parties do not get an appeal from any decision to institute an action. But in this case, that power precludes the right of the parties to end the case by a mutual settlement of their differences, so it is at least an open question whether the patent holder is entitled to have some escape from a process that he cannot terminate by ordinary means. In Cuozzo, the Court held that the statutory language was not limited to a denial of interlocutory appeals, but covered decisions to initiate cases as well.  Clearly, allowing appeals on an interlocutory basis is rarely wise, but the ability to stop a misguided suit before it begins has much more to commend it because it does not involve breaking up an ongoing suit. Nonetheless Justice Breyer, over dissent, held that the clear language of the statute covered the routine case before it. Accordingly, he rightly set aside cases that present constitutional issues or whose questions went outside the scope of the particular section. The decision is debatable, but defensible. But the result should be exactly the opposite whenever the Chief Judge exercises his power under the statute to stack the panel in favor of his preferred outcome, for there is no reason a party should have to fight a rigged trial to the bitter end when the objection is to the composition of the panel. In these cases, the ideal solution is a per se ban against this practice. But if the matter becomes an as-applied challenge, it should be resolved before anyone has to go through a proceeding that could well be invalidated because of problems at the outset of the proceeding.

B.    Claim Construction

Justice Breyer’s decision in Cuozzo is, however, far more troublesome for its rote invocation of Chevron, which in this instance allows the PTAB to fashion rules of claim construction, displacing the traditional rule of ordinary construction by an untested rule that allows the PTAB to give claims the broadest reasonable interpretation.  At this point, Justice Breyer again observes that the PTO may intervene in appellate decisions, even if the private challengers do not join in the appeal, without quite saying with the appellate court is bound by that rule of construction. Under the AIA, the burden of proof on the challenger, the PTO, or both is a bare preponderance of evidence instead of the higher standard of clear and convincing evidence,  which only increases the incentive for patent challengers to avoid the district courts. And the broader claim reading makes it more likely that any patent will be invalidated because it is more likely to infringe on a preexisting patent, for if it would not the parties would normally have opted for the broader construction anyhow. 

Any set of rules that abandons ordinary construction should be viewed with deep suspicion.  Yet the justification for using one standard before the PTAB and another in the federal courts is utterly unconvincing. Justice Breyer insists that, “in addition to helping resolve concrete patent-related disputes among parties, inter partes review helps protect the public's ‘paramount interest in seeing that patent monopolies . . . are kept within their legitimate scope.’"  The ellipsis in the quotation conceals the fact that the case cited, Precision Co. v. Automotive Company, was concerned with the state’s “paramount interest in seeing that patent monopolies spring from backgrounds free from fraud or other inequitable conduct, and that such monopolies are kept within their legitimate scope.”  No issue of claim construction or monopoly power was raised in Precision. It is therefore critical to ask why a novel test of claim construction is superior to the traditional test when the state also has a powerful interest in preserving incentives to invent by ensuring that inventors receive a just return on their inventions. Put otherwise, the social welfare and private incentives are well aligned under the traditional rule. Yet the Breyer opinion offers no word of explanation as to why a major deviation from that standard should be accepted. Cuozzo thus gives the PTAB the power to redraft substantive law, without any explanation of whether or why a reviewing court should accept its determination on that point. There is no such embarrassment if the disputed AIA provision is read to allow the PTAB to develop its own procedures to administer the standard legal rule. This decision converts the PTAB into a runaway train.

C.    Sovereign immunity 

One of the most litigated questions in recent years concerns the sovereign immunity of states with respect to suits brought by other states or private parties. The current law affords states immunity against suits by private parties,  but not by state governments.  It also holds that a state may voluntarily waive its defenses of sovereign immunity under the Eleventh Amendment , so as to allow the suits to go forward. The more difficult branch of sovereign immunity arises in those cases in which a state is deemed to have waived its sovereign immunity because of actions that it has taken prior to litigation. In Lapides v. Board of Regents of University System of Georgia,  the plaintiff sued the University of Georgia, alleging that it had improperly placed allegations that he had engaged in improper sexual harassment in his personnel file, in violation of state and federal law. The state removed the case to federal court, and the Supreme Court held that it thereby waived the defense of statutory immunity on the ground that it could generate unfair results to allow the state to first avail itself of federal jurisdiction only to then plead sovereign immunity.  It further noted that: 

[A]n interpretation of the Eleventh Amendment that finds waiver in the litigation context rests upon the Amendment's presumed recognition of the judicial need to avoid inconsistency, anomaly, and unfairness, and not upon a State's actual preference or desire, which might, after all, favor selective use of immunity to achieve litigation advantages.  

That result does not apply in any patent dispute because those must be litigated in federal courts. At this point, the question is why a state should be deemed to waive its immunity to IPR when it has no choice in where to go, given that the sole rationale in Lapides “was to prevent a State from selectively using its immunity to achieve a litigation advantage.”  In order to patch the hole in its argument, the PTAB cites New Mexico v. Knight,  which held that the states necessarily waived sovereign immunity against compulsory counterclaims, which had to be brought in the initial case or forever lost. But that precedent is completely inapposite in this instance. A state waives sovereign immunity to any compulsory counterclaim in federal court, but it hardly should be taken to waive the defense of sovereign immunity against IPR when it is not to their advantage to do so, and there is no reason for that to happen given that the federal district court offers a federal forum in which both sides compete on rough parity. Why would any state that has granted its opponent a federal forum ever throw itself into the lion’s den of the PTAB? There is accordingly no issue of fairness or strategic behavior that justifies the PTAB’s decision. Sadly, at no point did the PTAB opinion seek to reconcile its own opinion with those advanced in the cases it cited, or explain how the doctrine of sovereign immunity could ever come into play in cases where IPR is sought. Any case in which a tribunal such as the PTAB decides a case in favor of its own jurisdiction should be looked upon with deep suspicion, especially when the tribunal has never ruled in ways that have limited its power.

V.    Conclusion

The case law under the AIA is at a major turning point. The general perception in 2011 was that the AIA was making modest adjustments on a large number of technical points, with perhaps more profound changes on such matters as business method patents. It would be hard to find anyone who thought that the creation of IPR review would lead to a massive revolution in the operation of the entire patent system. But so it might be if the PTAB can control the agenda from top to bottom and transform the patent system into one that has the following features: stacked panels in favor of the views of the Chief Judge of the PTAB, no right to jury trial, a lower burden of proof to set aside a patent, no ability to settle out private disputes after the case is before PTAB, nonappealability of its decision whether to hear a case, a rule of claim construction that deviates from the well-settled rules of ordinary meaning, and an automatic waiver of sovereign immunity whenever a defendant removes a case from federal district court to the PTAB. These massive shifts are taking place without any showing that any of these reforms will do anything to improve the overall operation of the patent system. The traditional virtues of a system of separation of powers are made crystal clear by this litany of mistakes: the traditional regime lets the PTO decide which patents to issue, after which their protection is a judicial function. Oil States gives the Supreme Court the chance to stop a process that has already run off the rails. And if it does not, Congress should take steps to restore the proper constitutional balance.
