Supreme Court dodges decision of what is a patent

SAN JOSE, Calif. -- In a slim 5-4 majority, the Supreme Court decided not to endorse or define a test of what can be patented. Instead, it issued Monday (June 28) a narrow decision in the case of Bernard Bilski vs. the U.S. Patent Office.
The Supreme Court affirmed the Patent Office's rejection of a patent application on a business method for hedging financial trades submitted in 1997 by Bernard Bilski. But the high court did not settle the issue of what should be the limits for patents on processes defined in software and business-method patents.
Previously, a Federal court upheld the Patent Office's decision against Bilski. It also laid down a controversial test for any patent: it has to be tied to a device or transform something physical.
In a decision written by Justice Kennedy, the Supreme Court said the so-called machine-or-transformation test was one test that could be used. However it said the test was not exclusive and lower courts could set other tests as needed as long as they are in harmony with the existing Patent Act.
"It is clear that petitioners’ application is not a patentable process," said Justice Kennedy in his majority decision. "Today, the Court once again declines to impose limitations on the Patent Act [but] on disapproving an exclusive machine-or-transformation test, we by no means foreclose the Federal Circuit’s development of other limiting criteria that further the purposes of the Patent Act and are not inconsistent with its text," he added.
"Essentially, the Supreme Court realized how hard a subject this is and how fast technology is evolving and more or less punted the ball back to the Federal Circuit," said Edward Reines, a partner at Weil, Gotshal & Manges (New York, NY). "They said future rules will need to be developed to limit process patenting, and the machine-and-transformation test is too narrow," he said.
A broad range of electronics and biotech companies submitted briefs to the court arguing against a narrow definition of what is patentable. They included Dolby, Google, the IEEE-USA, Medtronic, Microsoft, Philips, Pitney Bowes, Red Hat and Yahoo.
"In general it was a pro-patenting ruling, and that collective sigh of relief you hear is from the software and biotech communities," said Reines. "A vote for the transformation test would have narrowed patents substantially for the software and biotech industries," he said.
Observers were split on their opinions of the ruling.
“After waiting more than seven months on Bilski, the Supreme Court’s decision is likely seen as a disappointment and let down," said Tom Chen a partner at Haynes and Boone
(Irvine, Calif.)
"The decision is green light with an accompanying flashing yellow," said Chen. "The good out of this decision is that the Court affirmed the viability of business methods, which is very important in today's economy with so many online businesses having innovations to protect, but the mixed signal comes by requiring lower courts to do a balancing test which gives no practical guidance to the PTO, patent attorneys and agents, and technology companies," he said.
Others praised the court's restraint.
"The opinion allows for a more flexible approach that will now better accommodate patent applications for diverse kinds of inventions, including software technologies and business methods, while pushing the U.S. Court of Appeals for the Federal Circuit to reconsider how it approaches tests for such patent claims," said Meredith Addy, chair of the appeals group at Brinks Hofer Gilson & Lione in Chicago, who wrote briefs for the case for parties including consulting firm Accenture.
Reines noted the 5-4 decision split the high court along ideological lines with the court decision backed by conservative Justices Alito, Roberts and Thomas with Scalia agreeing only to part of the decision. Justice Stevens wrote an opinion agreeing with the decision about the Bilski patent but providing a different rationale about the larger questions.
In the Steven's statement "four of the justices said that business methods should not be patentable at all," said Steve Baik, a partner at Orrick, Herrington & Sutcliffe LLP (Menlo park, Calif.).
"While business method patents won't be subjected to the rigid machine-or-transformation test, their continued viability is still precarious at best," Baik said. "At the very least, companies should attempt to draft patent claims that are likely to pass the still viable machine-or-transformation test to the extent possible," he said.
The split decision highlights the complexity and the need for greater clarity in the area. "Everyone knew this wasn’t a good patent application to raise the issue," said Reines.
Observers had predicted the court might take such a stance during oral arguments of the case in November.

What limits, if any, should government set on what can be considered patentable?

If it isn't something that you can feel, touch, hear, taste or smell or shouldn't be patentable. Lawyers and trolls are the only ones who benefit from patents anyways. I wouldn't patent anything. The protection it provides is dubious at best and simply gives the competition an easy way to steal your ideas and then you have to spend millions in legal fees to defend it.

Justice Stevens in his concurrence (page 38 of the opinion's .pdf) states this very clearly:
"The Constitution allows Congress to issue patents to promote the Progress of Science and useful Arts. This clause is both a grant of power and a limitation. It reflects a balance between the need to encourage innovation and the avoidance of monopolies which stifle competition without any concomitant advance in the Progress of Science and useful Arts."
Business is neither a Science nor a useful Art. Therefore business method patents are clearly not patentable, at least to a minority of justices. (At the time the Constitution was written, "useful Arts" meant the kind of stuff you learned in shop class, and that meaning has not been changed by amendment.)
On page 40, Justice Stevens adds:
"Although there is certainly disagreement about the need for patents, scholars generally agree that when innovation is expensive, risky, and easily copied, inventors are less likely to undertake the guaranteed costs of innovation in order to obtain the mere possibility of an invention that others can copy."
This is an excellent justification for the patents in development of semiconductor technologies and drugs where it costs millions to develop the technology and very little to copy it.
Software is not in that category. While a large software project can indeed cost millions, the effort put into each patentable idea is generally small and would have been performed as part of the large project whether or not it was patentable. Copyright is more than adequate to protect the effort of writing software and has created software giants like Microsoft and Apple. OTOH, the presence of software patents creates an infringement minefield that makes it essentially impossible to develop software without fear of future lawsuits. Given the huge cost in defending against both real and bogus infringement claims, the presence of software patents stifles competition and retards the Progress of Science and useful Arts with no concomitant benefit whatsoever.
This is only one of many reasons software should not be patentable.
So my answer is that neither business methods nor software should be patentable. I thank Justice Stevens for his long service to this country and we will miss his presence on the Court.

Do we need a better definition of what a patent is and is not?

Is algorithm patentable? Software means too many things. We can write unlimited number of garbage and buggy codes and call them software. But an algorithm that can instruct a machine to accomplish a special task should be patentable.

Can anyone answer Charlie's questions?
Charlie: I think algorithms fit into this grey area of processes and are patentable though there are no clear rules here.

IANAL, but here is my understanding.
Software by itself is not patentable. This was decided by Parker v. Flook (1978) in which Justice Stevens writes:
"Reasoning that an algorithm, or mathematical formula, is like a law of nature, Benson applied the established rule that a law of nature cannot be the subject of a patent. Quoting from earlier cases, we said: `A principle, in the abstract, is a fundamental truth; an original cause; a motive; these cannot be patented, as no one can claim in either of them an exclusive right.' [Le Roy v. Tatham, 14 How. 156, 175.] Phenomena of nature, though just discovered, mental processes, and abstract intellectual concepts are not patentable, as they are the basic tools of scientific and technological work." [409 U.S., at 67.]
My opinion: the court recognizes that non-patentability of mathematics and algorithms is essential to Progress of Science and useful Arts, since if one could patent fundamental steps a monopoly could block progress in an entire field. Furthermore, one cannot patent a purely mental process since that would allow a monopoly to control what people were allowed to think. Software running on a general-purpose computer is merely automating a mental process, so it should not be patentable either.
However, a process that includes software as a key component is patentable provided that the process as a whole performs a physical transformation or requires a special-purpose machine. This is the "Machine or Transformation Test" and was decided by Diamond v. Diehr (1981) which determined that a process for curing rubber was patentable since the algorithm involved caused a physical transformation.
So this should settle it, right? Well, actually not since patent lawyers are adept at rewording a software patent to confuse the patent examiner into thinking it's not a pure abstraction. Patents never say "an algorithm to"... it's always "a method to..." It's remarkably easy to get a patent in the USA: approximately 90% of patent applications are awarded, according to Dan Ravicher in a recent speech: http://www.softwarefreedom.org/podcast/2010/may/25/episode-0x28-dans-software-patent-presentation/. He also makes the comment that the USPTO sees itself as a "patent granting agency" and not a "patent denying agency". It's all very well to say "we'll let the courts decide this" and "Bilksi proves the system works", but the reality is that it can cost millions of dollars to defend against even a bad patent and costs industry billions of dollars a year which could otherwise be used to develop products.
It's also ambiguous as to what is an "abstract" process. The Bilski opinion written by Justice Kennedy denies Bilski's patent on the basis that it's "abstract", but does not really define what "abstract" means. Plus, it says the Diehr's "Machine or Transformation" test is only "a clue" rather than a definitive test. So it's left to lower courts and/or future cases before the Supreme Court to decide these things, meanwhile costing industry billions of dollars a year and distracting creative engineers from technical problem solving.
There is also some ambiguity as to whether there is a difference between algorithms (a series of steps) and mathematics (a closed formula). In fact, the Church-Turing thesis showed this ages ago.

I am frustrated with today's patent process. The patent processes integrity has continued to dwindle here in the U.S. When this whole issue arose some years ago (business process/method patents)I felt the system was in trouble. Pretty soon someone will want to patent "thinking"
If you ever get the chance, do go to the USPTO get a library card and browse the racks of Patents. The most enjoyable library visit I've ever made.

The Software Freedom Law Center has an excellent oggcast summarizing the Bilski opinion: http://www.softwarefreedom.org/podcast/2010/jun/29/episode-0x2b-bilski-rundown/
The SFLC site has lots of other Bilski and software patent information as well.
