Prominent Pro-Patent Judge Issues Opinion Declaring All Software Patents Bad

from the and-over-an-intellectual-ventures-lawsuit dept

Well here’s an unexpected surprise. A lawsuit brought by the world’s largest patent troll, Intellectual Ventures, and handled on appeal (as are all patent cases), by the notoriously awful Court of Appeals for the Federal Circuit (CAFC) may have actually killed off software patents. Really. Notably, the Supreme Court deserves a big assist here, for a series of rulings on patent-eligible subject matter, culminating in the Alice ruling. At the time, we noted that you could read the ruling to kill off software patents, even as the Supreme Court insisted that it did not. In short, the Supreme Court said that any patent that “does no more than require a generic computer to perform generic computer functions” is not patent eligible. But then it insisted that there was plenty of software that this wouldn’t apply to. But it’s actually pretty difficult to think of any examples — which is why we were pretty sure at the time that Alice should represent the end for software patents, but bemoaned the Supreme Court not directly saying so, noting it would lead to lots of litigation. Still, the impact has been pretty widespread, with the Alice ruling being used both by the courts and the US Patent Office to reject lots and lots of software and business method patent claims.

But this latest ruling, from the very court that upended things nearly two decades ago in declaring software much more broadly patentable than anyone believed, may now be the nail in the coffin on software patents in the US. The headline, of course, is that the patents that Intellectual Ventures used against anti-virus firms Symantec and Trend Micro, were bunk, because they did not cover patent eligible subject matter. But the part that has everyone chattering is the concurring opinion by Judge Haldane Mayer, that says it’s time to face facts: Alice killed software patents. And Mayer is not some newcomer. He’s been at the Federal Circuit since the 1980s and was actually the chief judge in the late 90s/early 2000s when CAFC was at its worst in terms of expanding patent law. And it appears he’s been born again into the anti-software patent world. It’s… quite a conversion.

Even better, Judge Mayer pointed out that the First Amendment says that such patents should not be allowed. The whole concurrence is worth reading, but we’ll highlight some key points, starting with the First Amendment argument — which is kind of fascinating in that it goes well beyond what most people had talked about in the past concerning software patents.

?[T]he Constitution protects the right to receive information and ideas. . . . This right to receive information and ideas, regardless of their social worth, is fundamental to our free society.? Stanley v. Georgia, 394 U.S. 557, 564 (1969) (citations omitted). Patents, which function as government-sanctioned monopolies, invade core First Amendment rights when they are allowed to obstruct the essential channels of scientific, economic, and political discourse.

Wow! That’s actually great to see — and the kind of argument that we’d hoped to see around copyright. But we’ll take it on patents. Here, Judge Mayer notes, the real issue is that this patent would basically harm free expression on the internet, making it ineligible to be patented.

Just as the idea/expression dichotomy and the fair use defense serve to keep copyright protection from abridging free speech rights, restrictions on subject matter eligibility can be used to keep patent protection within constitutional bounds. Section 101 creates a ?patent-free zone? and places within it the indispensable instruments of social, economic, and scientific endeavor…. Section 101, if properly applied, can preserve the Internet?s open architecture and weed out those patents that chill political expression and impermissibly obstruct the marketplace of ideas.

From there, Judge Mayer notes that if everyone just recognized that the Supreme Court outlawed patents with Alice, the First Amendment questions wouldn’t even come up at all.

Most of the First Amendment concerns associated with patent protection could be avoided if this court were willing to acknowledge that Alice sounded the death knell for software patents. The claims at issue in Alice were directed to a computer-implemented system for mitigating settlement risk…. Although the petitioners argued that their claims were patent eligible because they were tied to a computer and a computer is a tangible object, the Supreme Court unanimously and emphatically rejected this argument…. The Court explained that the ?mere recitation of a generic computer cannot transform a patent-ineligible abstract idea into a patent-eligible invention.?… Accordingly, ?[t]he fact that a computer necessarily exist[s] in the physical, rather than purely conceptual, realm is beside the point? in the section 101 calculus.

From there, Judge Mayer makes the point (that some of us tried to make post-Alice), which the Supreme Court refused to say outright, and which many patent lawyers refused to admit: under the test in Alice, basically all software is unpatentable. And that’s fine because software is “a form of language” and we don’t patent language.

Software is a form of language?in essence, a set of instructions…. It is inherently abstract because it is merely ?an idea without physical embodiment,?… Given that an ?idea? is not patentable… and a generic computer is ?beside the point? in the eligibility analysis … all software implemented on a standard computer should be deemed categorically outside the bounds of section 101.


And, finally, it appears that a CAFC judge recognizes (citing a bunch of great amicus briefs and papers about how patents have little to do with incentivizing software development) what many in the software field have been saying for decades: software succeeds in spite of patents, not because of it:

Software development has flourished despite?not because of?the availability of expansive patent protection. See Brief of Amicus Curiae Elec. Frontier Found. in Support of Respondents, Alice, 134 S. Ct. 2347 (No. 13- 298), 2014 WL 828047, at *6?7 (?EFF Brief?) (?The software market began its rapid increase in the early 1980s . . . more than a decade before the Federal Circuit concocted widespread software patents in 1994. . . . Obviously, no patents were needed for software to become a $60 billion/year industry by 1994.?); Mark A. Lemley, Software Patents and the Return of Functional Claiming, 2013 Wis. L. Rev. 905, 935 (2013) (?Software patents . . . have created a large number of problems for the industry, particularly for the most innovative and productive companies. . . . [T]he existence of a vibrant open source community suggests that innovation can flourish in software absent patent protection.? (footnote omitted)); Wendy Seltzer, Software Patents and/or Software Development, 78 Brook. L. Rev. 929, 930 (2013) (?Seltzer?) (?Present knowledge and experience now offer sufficient evidence that patents disserve software innovation.?); Arti K. Rai, John R. Allison, & Bhaven N. Sampat, University Software Ownership and Litigation: A First Examination, 87 N.C. L. Rev. 1519, 1555?56 (2009) (?While most small biotechnology firms that receive venture financing have patents, the available empirical evidence indicates that most software start-ups that receive venture financing, particularly in the first round, do not have patents.?).

But Mayer goes even further in this discussing four separate problems with the whole concept of software patents, including the fact that the scope of the patents greatly exceeds the importance of what they disclose. Second, he notes that “they provide incentives at the wrong time” — recognizing a key point we’ve made for years: that an idea is basically worthless when compared to the actual execution (to me this applies to more than just software patents):

Because they are typically obtained at the ?idea? stage, before any real inventive work has been done, such patents are incapable of effectively incentivizing meaningful advances in science and technology. ?A player focused on patenting can obtain numerous patents without developing any of the technologies to useful levels of deployment or disclosure, leaving a minefield of abstract patent claims for others who actually deploy software.? Seltzer, 78 Brook. L. Rev. at 931. Here, for example, it took no significant inventive effort to recognize that communications should be screened for harmful content before delivery. The hard work came later, when software developers created screening systems capable of preventing our email boxes from being overrun with spam or disabled by viruses. Granting patents on software ?ideas??before they have been actually reduced to practice?has created a perverse incentive scheme. Under our current regime, those who scamper to the PTO early, often equipped with little more than vague notions about using computers to automate well-known business and social practices, can reap hefty financial dividends. By contrast, those who actually create and deploy useful computer-centric products are ?rewarded? with mammoth potential infringement liability.

The third problem he discusses is the fact that the system is overwhelmed with software patents, “most of which are replete with broad, functional claims” which makes it “virtually impossible to innovate in any technological field without being ensnared by the patent thicket.” Nicely put. And because of that:

Software patents impose a deadweight loss on the nation?s economy, erecting often insurmountable barriers to innovation and forcing companies to expend exorbitant sums defending against meritless infringement suits.

Finally, he notes that software doesn’t deserve patent protection because “generically implemented software invariably lacks the concrete borders the patent law demands.” As he notes, a patent system only functions when it’s clear what the boundaries are of what’s covered. But that’s not the case at all with software patents.

Software, however, is akin to a work of literature or a piece of music, undeniably important, but too unbounded, i.e., too ?abstract,? to qualify as a patent-eligible invention.

From there, he suggests that the courts (and I guess the Supreme Court) should just stop punting on the issue and declare software patents dead:

Declaring that software implemented on a generic computer falls outside of section 101 would provide muchneeded clarity and consistency in our approach to patent eligibility. It would end the semantic gymnastics of trying to bootstrap software into the patent system by alleging it offers a ?specific method of filtering Internet content,?….

The opinion is a great read overall — and it’s the kind of arguments that plenty of folks in and around tech and software patents have been making for years. But to see it come out of a judge’s pen, in a patent case, and from CAFC, is what’s really incredible. Of course, as a concurring opinion, rather than the majority opinion, by itself the opinion holds no precedential value. That’s too bad. But it does suggest that even CAFC judges are recognizing how ridiculous software patents are these days. It will be interesting to see if Intellectual Ventures tries to kick this up a level to the Supreme Court, where it might risk SCOTUS actually agreeing with Judge Mayer.

Just think of all the value held by corporations with huge software patent portfolios that will now be worthless. Wall Street will go crazy. Accountants will get a short term boom while they spend countless dollars reevaluating corporate assets.

In addition, there will be terrible noise pollution as the patent trolls die a horrible and justly deserved death, which we will unfortunately have to listen to. Or not.

Re: Re: Re: Oh Noes

Erm, this has nothing to do with the election. You’re right about neoliberalism and the neocons, though. This is indeed their doing; by turning intellectual output into property they can increase the rentier economy. What the robber barons of the last century did with land, they’re doing with ideas and it’s causing the exact same problems.

Notice that the ideology hasn’t changed, only the name. Neocons are colonialists with a nasty case of White Man’s Burden and neoliberalism is corporatism.

Twirrim says:

Re: Oh Noes

In No small part, a good number of those patents have had to be applied for defensively. When every competitor holds them, you have to hold them too. It’s like a nuclear arsenal.

Without that arsenal you’re defenceless against those who do have it. With it, you’re able to get to an impasse. “You sue us for this, we’ll sue you for that”.

Disarming those weapons doesn’t harm most of the companies involved, nor inhibit their ability to compete in the market. The only ones affected are those with no competitive product in the first place.

In case a lot of people aren’t making it to the bottom of the original post…

The language everyone is fixated on comes from a concurring opinion, not the opinion of the majority of the court, and is therefore not binding precedent. More interesting academically, at least unless and until Mayer can persuade a majority or the Supreme Court adopts his viewpoint (which isn’t likely to happen soon).

Can this be applied to the circumvention clause in the DMCA?

Steerpike (profile) says:

Re: Re:

You could certainly make a similar argument, but I’m not convinced you’re going to get a court to accept it. The First Amendment has never been recognized as absolute, and while I personally favor an expansive reading of the First Amendment I think you’ll have a hard time convincing a court that the DMCA anti-circumvention provision violates it. All copyright covers information, so the same argument could be made with respect to any copyright, which clearly goes against the intent of the Constitution. Even if you could get there in patents, I don’t think it likely it would be expanded.

Bobs Your Uncle (profile) says:


Doubtful, since DMCA implementations are typically applied to content that is exchanged pursuant to a mutually agreed upon business transaction, & entered into freely by both the provider & consumer.

Now, if some would-be, self-appointed gatekeeper (think ISPs) were to try & interpose DMCA implementations between content made available by unaffiliated providers to the unaffiliated consumers of that content, without the prior consent of both the content provider & consumer, that’s a different kettle of fish entirely.

I hate the use of the word “freely” in that context; it smacks of false equivalence, as the degree of “freedom” enjoyed by the two parties is remarkably unequal.

In simplest form, the problem with software patents is that not only is the formula patented, but so it the outcome. Here is my example
Company A: 10+10=20
Company B: 4*5=20
Company C: 25-5=20
Company D: 40/2=20
Company E: Sqrt(400)=20
Company F: Method of creative an output of 20. (log 16.043)^16.043=20
Companies A – E all use different values and different mathematical functions to create 20. Yet if Company F was the first to patent, then Companies A – E would be sued.

If a pharmaceutical company tried this, Method of relieving pain via oral ingestion. It would be rejected immediately. You need specific unique formulas

I was very disturbed by this article. I wrote a paper on this back in the 1990s. First this is not a constitutional issue (the constitution did not designate “patents” “copyrights” and what their respective contents are… these are laws passed many years ago. What I propose in this article is to get back to basic to protect intellectual property “for a time” …but dependent on a more realistic notion of what “for a time” means according to the property in question. The paper is at

I’m thinking the reason no one cares about this is that was a word salad of I don’t even know, and demonstrates very clearly that a PHD doesn’t make you smarterer software is not like things there are very limited boundaries and patentablity requires uniqueness, that is not an accident otherwise I could sue you for your lemanaid(that auto correct thinks this word is middleman amuses me to no end) stand.

Trade secrets are not patents, one you must protect yourself the other gives you a legal monopoly, enforced by many large men with guns, these are not equivalent propositions.

Re: Re: Software Patents

Please learn correct spellings of “smarter” and “lemonade”, because you obviously are less intelligent than me. Probably because YOU are one without a proper education, therefore you are ignorant to this subject and your opinion is invalid.

Another thing you have to learn is that sentences ALWAYS starts with a capital letter and you always put a space before a parenthesis.

Plus, a man needs to be able to own an idea or a process so he is able to profit from it. For a reasonable time, yes, but there’s really nothing wrong with copyright or patent system other than in some cases it lasts too long, which you would know, if you had the mental capacity to actually understand my paper.

Re: Re: Re: Software Patents

To profit from an idea requires an execution of the idea, and marketing ability, which is why teams like Steve Jobs/Steve Wozniak and Bills Gates/ Paul Allen were successful, and in both cases the most famous name is that of the marketing guy.
Most inventors fail not because they cannot protect their ideas, but rather because the cannot finalize a product, and they cannot market their product. The best option for someone with an idea is to find a business partner who will reign in their tinkering, and who can sell the resulting product.

By making this statement and holding the view you have expressed, you have shown yourself to be less than anyone else here.

A person’s intelligence, education and knowledge are irrelevant as to whether an opinion is a valid opinion. An opinion is always valid. It may be wrong, it may be lacking, incorrect, limited, sorta right, close, far, good, bad, spot on, way off base. But it is still valid.

If you make the basis of whether even to consider an opinion on the educational and intelligence level of the person expressing the opinion, then you are an elitest, bigoted, limited, arrogant prick.

You are the one showing ignorance.

Most of the great discoveries in the 19th century, prior to the establishment and promulgation of the modern scientific method, were based on ignorance. Many of them were based on pure experimentation with no knowledge of why or what was happening, just that something was. Yet many great discoveries were made.

If an elderly but distinguished scientist says that something is possible, he is almost certainly right; but if he says that it is impossible, he is very probably wrong.”

―Arthur C. Clarke

Just because someone is lacking in education doesn’t mean they can’t, in fact often means they can, make fundamental contributions. It’s usually those who are ignorant of the perceived wisdom of a field that can cut through that preceived wisdom and do what the educated establishment have flat-out stated is impossible.

Re: Software are maths

And he did nobody any good service. Instead he wasted an incredible amount of effort trying to explain high-level mathematics and why software was math because of his explanation that nobody else could follow.

Ping – nut job, ignore. So he accomplished very little.

Now we have the SCOTUS saying (finally) that ‘doing on a computer’ or ‘the intertubes’ doesn’t mean they can bypass 101.

I am nearly finished with the brief but the consenting opinion actually states the issue much more clearly than the groklaw mathhead ever did. Software isn’t tangible, it is an idea. There’s your QED right there. Ideas cannot be patented.

His view regarding the First Amendment is pretty clear as well. The society is built on freedom of expression, software are ideas and you cannot let the entire computing landscape be ‘balkanized’ (great line) by patents as they are trampling on free speech.

He also states the computer has become ‘the basic tool’ for everyone, for nearly every aspect of modern life. Thus restricting access violates the basic freedom of everyone.

And he did it without any math.

The FTC is growing a pair

Fair Use quotes,
“The Federal Trade Commission has released a study of Patent Assertion Entity (PAE) Activity—dubbed “patent trolls” by their critics—and recommended reform of the patent assertion process.

PAE’s say this in response
“It is important to remember that patent licensing plays a vital role in bringing new technologies and medical breakthroughs to market. It critically allows innovators to focus on inventing and research, instead of manufacturing, sales and marketing.” (my emphasis)

I just don’t understand patents today.

Here’s a quote from Intellectual Ventures this past week,

“If we own a patent … if we don’t make (a product) that means we make nothing, so we just try to license them to people or sell them to people or create companies around them,” Myhrvold said. “I think that is probably the friendliest use of patents.”

Seriously, I really don’t understand how ideas can be patented without a working prototype product.

The reason I say this is simple, in the U.S. patents are holding back innovation. Startups can’t afford to go to court, where PAEs have the money to.

Meanwhile patent unfriendly/reasonable countries are building products (from tech to pharma) that help their citizens without bankrupting them by ignoring patents.

From my perspective, the current state of patents is making the United States fall behind other countries that hold (in my view) a more reasonable approach to patents.

The final dissenting opinion has his facts wrong.

The last of the PDF has a dissenting opinion that partially disagrees with the rest of the court. In his view the scanning of files not on the users computer but before it gets to the user is valid 101. Because it was new and innovative (at least that is how I read his piece).

Sadly he is wrong.

Email/content scanners as individual servers were actually sold *before* the patent application. One could purchase a rack server that received all email and the spam would be extracted and included virus/malware would be squashed. As it was in a separate box (system/server) this was definitely happening off the users computer and before the genius of ‘doing on a different computer’, which still fails 101. This is doing it on a different but still generic computer.

The advent of the cloud and virtualized computers all came after the reality of multiple servers working in farms to support the corporation (and the public). Email scanning was big business as Spam Was King. It is less so now, but scanning email before it got to the user is old news.

It really is a shame this wasn’t the majority opinion. Hopefully this will lead to better judgments being made from now on.

Joeri says:

Point of law

The judge makes some fine arguments on why software patents are bad, and I agree wholeheartedly. However, I’m less convinced on the points of law. If the supreme court thought that software patents shouldn’t exist as a point of law, they wouldn’t have found over and over again that they should.

Yes, software patents are bad, but they’re the way the law works. Only a change in legislation can get rid of them. As long as congress remains pro-software-patent there’s very little the court can do to counter that.

software patents surviving Alice

I don’t thine Alice invalidates all software patents, just most.

does no more than require a generic computer to perform generic computer functions

It invalidates software patents that run on generic computers.

What I don’t think it invalidates are software patents for specific-purpose computing devices. E.g industrial control systems like the firmware embedded in CnC mills, ABS braking sytems in vehicles, flight control systems that allow fly-by-wire, engine management systems like EFI, medical equipment like pacemakers, printer firmware that controls the printing functions, and so on.

Angetenar says:

Re: Re: software patents surviving Alice

But the hardware in all those cases is still a general-purpose computer, right? As in, Turing-complete?

No. Being “Turing-complete” does not make a computer’s purpose general.

If you can hack printer firmware to run Doom, then it’s a general-purpose computer.

Again, no. Being able to hack a printer to do something it was not intended to do does not alter the printer’s intended purpose.

Anonymous Coward says:

Re: Re: Re: software patents surviving Alice

A general purpose computer is simply a computer whose purpose is determined by the software loaded on it, and to a lesser extent the peripherals attached via the IO ports. A special purpose computer, on the other hand is hardwired to perform a specific task, and rather than being reprogrammed, it is rewired to work on a different task, i.e. an analogue computer.
