Opinion analysis: The uncertain expansion of judge-made exceptions to patentability

John Duffy is theSamuel H. McCoy II Professor of Law at University of Virginia School of Law.

Although Alice Corp. v. CLS Bank was identified by this website and many other commentators as a major case on patent law, the Supreme Courts unanimous resolution of the case does little to change, or even to clarify, pre-existing law. The case becomes the fourth Supreme Court decision since 2010 to hold patent claims invalid based on judicial exceptions to patentability. While Alice Corp. is only an incremental addition, the continuation of that larger trend is hugely important because, as the Court itself acknowledges, the judge-made doctrine in this area has the potential to swallow all of patent law.

Alice Corporation is a holder of several issued patents directed to computerized methods for mitigating so-called settlement risk in financial transactions i.e., the risk that one party wont live up to its obligations. As a concrete example of the problem, Alices brief posited a transaction in which one party wants to buy, and another to sell, Japanese yen for U.S. dollars. The dry language of the brief explains that [o]ne risk associated with such transactions is that only one side will perform the exchange at settlement, and the risk of such one-sided performance is referred to as settlement risk.

Obviously, settlement risk is a significant problem. Parties to a financial transaction dont want to perform their end of the bargain only to have the other side default. Id hate to give up my dollars and get no yen in return! Settlement risk is, however, also a very old problem, and one very old solution to this problem is to use a trusted intermediary to assist in settlement. Indeed, the intermediated settlement is such an old solution that the Supreme Court was able to cite a book from 1896 thats right, from the nineteenth century (!) that accurately described the basic process.

For Alice Corporation, it is not a positive aspect of the case to put it mildly that an 1896 book describes the basic process of intermediated settlement. After all, a fundamental pillar of patent law is that a patent must cover only the new, not the old. The 1896 book did not, of course, disclose the use of a computerized system to act as the intermediary, and Alices argument in a nutshell was (in language that the Court quoted from Alices briefs) that, under its patented methods, [t]he computer itself was the intermediary.

Alices patents can be accurately described as falling into a common category of questionable patents that take an old practice and update it with the addition of computerized techniques. The problem with such patents is that such updating is often very, very easy to do. Imagine, for example, as soon as the telephone was invented, someone applied for a patent on the process of ordering goods using a telephone call (as opposed using the mails). The text of the Patent Act has a specific doctrine that is precisely tailored to preclude such patents. Under 35 U.S.C. 103, a patents may not cover obvious extensions or combinations of pre-existing technologies.

If the Supreme Court had invalidated Alices patents using the obviousness doctrine in Section 103 of the Patent Act, almost no one would think twice about the decision. The difficulty and the real root of the controversy here is that the Supreme Court is not relying on any language in the Patent Act as the basis for its decision. Rather, the Court in this case (and in its three prior cases in the last four years) has been relying on doctrines that, as the Court stated four years ago in Bilski v. Kappos, are not required by the statutory text. In other words, they are judge-made exceptions to patentability.

Now at this point, anyone not steeped in patent law might justly wonder: why does it matter whether Alices patents are invalidated under judge-made exceptions to patentability rather than a specific statutory doctrine such as the obviousness doctrine? The answer is that it may and I emphasize here may matter quite a bit both theoretically and practically. Here are four reasons to think it matters.

First, as a theoretical matter (and since Im an academic, Ill start with the theory), it is highly interesting that this Court has embraced and expanded judge-made exceptions to patentability. A majority of Justices on this Court purport to be textualists in matters of statutory interpretation, and yet in this pocket of federal statutory law, even the textualist Justices seem to think nothing of allowing judge-made exceptions to patentability to steal the show from the doctrines written into the Patent Act by Congress. Indeed, the decision was written by Justice Thomas, one of the most conservative members of the Court and, in other contexts, one of the Justices most likely to stick closely to the text of a statute. It is an ongoing mystery as to why the textualist Justices have been so willing to interpret these judge-made exceptions liberally and expansively.

Second, the practical difference between the judge-made and statutory limitations on patentability could be enormous. While Alices patents seemed to be a rather obvious application of fast, modern computers to automate very old methods of intermediated settlement, the judge-made exceptions to patentability are not limited to such situations.

The judge-made exclusions preclude patents on laws of nature, natural phenomena, and abstract ideas. Yet the Court itself recognizes that at some level, all inventions embody, use, reflect, rest upon, or apply laws of nature, natural phenomena or abstract ideas. Thus, the Court itself recognizes that it must tread carefully in construing its judge-made exclusionary principle to patentability lest it swallow all of patent law.

If you want to know whats important about this case, its right there: the Courts acknowledgement that the judge-made exclusionary principle has the potential to swallow all of patent law because all patents are at some level based on the very things that cant be patented under the judge-made doctrine. If you are a patent holder, thats more than just a bit worrisome. If you are opposed to patents, its cause for dancing in the streets.

Third, theres the enormous uncertainty associated with the judge-made doctrine in this area. Given the Supreme Courts explicit acknowledgment that the judge-made exclusionary principle to patentability could swallow all of patent law, one might think that the Court would be very careful, and very clear, in demarcating a limit on the doctrine so that lawyers and lower court judges would know which patents should fall, and which should survive, the analysis. Yet the Supreme Court has been remarkably resistant to providing clear guidance in this area, and this case continues that trend.

For example, on the crucial question of what constitutes an abstract idea for purposes of the judge-made exclusion to patentability, the Courts opinion here explicitly states that it will not labor to delimit the precise contours of the abstract ideas category in this case. Instead, the Court merely holds that theres no meaningful distinction between the concept of risk hedging [held unpatentable] in Bilski and the concept of intermediated settlement at issue here. That may be fine for today, but tomorrow the lower courts and the Patent Office will have to labor and labor mightily to try to figure out the precise contours of the category.

After the Court decides that an abstract idea does underlie the patent here, it still has to determine whether the specific patent claims in the case do more than simply instruct the practitioner to implement the abstract idea of intermediated settlement on a generic computer. On this point, the Court gives precisely one page of analysis, which concludes with the statements (i) that the claims at issue here amount to nothing significantly more than an instruction to apply the abstract idea of intermediated settlement using some unspecified, generic computer, and (ii) that is not enough to transform an abstract idea into a patent-eligible invention.

Ill have to teach this enough test next semester. Ill be sure to use italics, just like the Court did, but Im not convinced that even with the different font, the enough test will give much guidance to my students, or to the lawyers, judges and Patent Office officials who will have to apply it to numerous other situations. Indeed, if this is the type of guidance the Court intended to give, one might fairly wonder why it granted certiorari in the first place, especially given that the Federal Circuit had reached the same result below.

International considerations provided the fourth and final reason why this line of cases is important. While these cases involve only U.S. law, other countries often look to U.S. doctrine in fashioning their own patent law. Some of those countries may not be pre-disposed to supporting patent rights, especially patent rights held by foreign patentees. Those countries might be quite willing to embrace, vigorously, a judge-made exclusionary principle that has the acknowledged capability to swallow all of patent law if judges and other decision-makers do not tread carefully in applying it.

The Courts decision in this case reminds me of a line from the classic 1965 movie The Battle of the Bulge. Towards the end of the movie, the German panzer colonel believes he has succeeded in breaking through the Allied lines, and he exalts: We have done it! His attendant asks whether we have won the war. The colonels answer: no. The attendant then whether you mean we have lost. Again, the colonel replies, no. The confused attendant asks, What is happening? The happy answer from the militaristic colonel: The best thing possible is happening – the war will go on.

More than anything else, that message seems appropriate in the wake of this case. Both sides on the battle over the reach of judge-made exceptions to patentability looked upon this case as having the potential to deal a knock-out blow to the other side, or at the very least, to demarcate some lines dividing the patentable from the unpatentable. The Court chose not to provide such guidance. The war will go on.
