KSR v. Teleflex (Supreme Court 2006, Oral Arguments).

The doctrine of nonobviousness is the cornerstone of American patent law.  I was reminded today by Phil Swain that our nonobviousness statute, section 103(a) of the Patent Act, was drafted by Judge Giles Rich.  Judge Rich is the most celebrated patent judge of this century.  His statutory masterpiece eliminated the amorphous concept of a “flash of genius” and replaced it with our now ubiquitous objective standard of a person having ordinary skill in the art.  In Graham v. John Deere, the Supreme Court reinforced 103(a) with its concept of case-by-case consideration of secondary indicia of nonobviousness as a way to avoid potential hindsight bias. 

Later, as the Federal Circuit developed its own patent jurisprudence, the court hit upon the teaching-suggestion-motivation test as another anti-hindsight rule.  That test requires evidence of some reason to combine various references that each teach part of an invention.  Thus, if there is no evidenced reason to combine the references, then the invention will be deemed nonobvious. The test, known by acronymists as “TSM,” has been labeled as a poster-child for bad patent behavior.  According to opponents of the test, the bright-line test makes patents too easy to obtain — resulting in a glut of patents covering trivial improvements. Those patents, in turn, hold-up industry research and greatly increase transaction costs and legal fees. 

In KSR v. Teleflex, the Supreme Court is questioning whether the TSM test should exist as the sole determinant of obviousness.  Question presented:

Whether the Federal Circuit has erred in holding that a claimed invention cannot be held ‘obvious’, and thus unpatentable under 35 U.S.C. § 103(a), in the absence of some proven “‘teaching, suggestion, or motivation’ that would have led a person of ordinary skill in the art to combine the relevant prior art teachings in the manner claimed.”

Until a few months ago, the common myth of the TSM test was that it required at least some hard evidence that provided at least a minimal reason to combine various prior art references.  It is that myth that provided the impetus for Supreme Court review. In recent months, however, we have learned that the CAFC’s version of the test allows for evidence that is implicit, based on common knowledge, found generally in the prior art as a whole, based simply on the nature of the problem or simple logic, or concluded by experts. See Kahn, Dystar, Ormco, Alza.  This jitterbug by the CAFC actually gives KSR much of what it wanted and smears the edges of the mythical bright-line rule.  Justice Scalia picked up on transition during oral arguments — noting that the recent cases leave the test “meaningless. [The CAFC] essentially said ‘our test simply reduces to what [KSR seeks] in this litigation.’ . . . this is gobbledygook. It really is, it’s irrational.” Justice Alito had a similar concern with the “new” TSM test:

J. Alito: “But what is the difference between asking whether something is implicit in the, in the prior art and simply asking whether it would have been obvious to a person of ordinary skill in the art?:

As discussed earlier on Patently-O, all the major patent bar associations filed briefs that support the current TSM test.  In a brilliant move, KSR neutralized those briefs by implying bias based on “the enormous fees that litigation of invalid patent claims can generate.” KSR Reply Brf. CJ Roberts appeared to buy-in to that analysis, joking that the filings “just indicate[] that this is profitable for the patent bar.” KSR Oral Arg.

One concern of the Court is whether modification of the obviousness doctrine would spoil long-settled rights.  The Justices, however, mentioned on several occasions that over the past year, the CAFC may have already upset any settled rights.

Mr Goldstein [for Teleflex]: “[The CAFC has had decades to look at this to try and elaborate a standard.”
J Breyer: “And it so quickly modified itself.”

Decision in February: Reports from the hearing noted that Justice who used the term “TSM” spoke with disdain and were highly critical of the test.  Although oral arguments are always full of counterfactuals and wild theory testing, the level of criticism supports the conventional wisdom that the TSM test is likely to be eliminated as “the exclusive” test.  Cases will rather be decided on a case-by-case basis using the standards of Graham v. John Deere. Already issued patents will still be given a presumption of validity, although it will be difficult for some courts to do this with a straight face.  The new key to avoiding invalidity will be secondary indicia of nonobviousness. Look for a 9–0 decision in early February.

TSM is not Dead: Much of the oral argument was filled with an attempt to simply understand the TSM test, and to figure out what is meant by a “motivation.”  If they cannot figure-out the test, they would likely completely trash-it as unworkable. Of course, by the time the opinion is penned, they will understand the current test and the test will not be scrapped as a whole. Rather, they will follow the Government’s suggestion that TSM continue to be used as a “valid means of proving obviousness.” In addition, however, flexibility will be added to allow for other ways of determining nonobviousness.

Here are some quotes from oral arguments:

CJ Roberts: “[T]the Federal Circuit’s approach focuses . . . on prior art — as opposed to, I would say, common sense.” 

J Scalia: “And in the last year or so, after we granted cert in this case after these decades of thinking about [the obviousness doctrine, the CAFC] suddenly decides to polish it up.”

J. Breyer: “I’ve read it about 15 or 20 times now, I just don’t understand what is meant by the term ‘motivation.’”

Mr. Hungar [for US Gov’t]: “Construed as the sole means of proving obviousness the teaching suggestion motivation test is contrary to the Patent Act, irreconcilable with this Court's precedents and bad policy. It asks the wrong question and in cases like this one, it produces the wrong answer. It should be rejected and the judgment of the Court of Appeals should be reversed. . . . It’s just foreign to this Court’s precedents as a mandatory prerequisite for obviousness.”

Mr. Dabney [for KSR]: “[T]here is no legal regime that is a greater generator of patent litigation than the teaching suggestion motivation test that is urged by the respondent.” [DDC: Is this true?].

Amgen v. HMR (CAFC en banc denial)

Cybor is the much reviled CAFC decision holding that the construction of patent claim language is a question of law that is reviewed de novo — without any regard to the lower court’s reasoning or ruling.  The Cybor rule is believed by many to have dramatically increased uncertainty in patent litigation as well as likelihood of appeal.  Importantly, the associated reversal rate also demoralizes district court judges who already often struggle with the technical and legal complexity of patent cases.

In Amgen, the appellate panel reviewed construction of the term “therapeutically effective amount” of erythropoietin and, in the process illustrated how Cybor gives the court a “capacity for arriving at its own idiosyncratic construction.” (Quoting Prof. Kevin Noonan). Here, the CAFC panel reversed the lower court’s construction based on its interpretation of the specification. 

HMR’s request for rehearing en banc has been denied, but a contingent of six separate dissenting and concurring opinions show the internal conflict.

Chief Judge Michel, who also dissented from the original panel decision, led the charge against Cybor. “I have come to believe that reconsideration is appropriate and revision may be advisable.”  CJ Michel, who was joined in the opinion by J Rader, cited four practical reasons for eliminating de novo review:

1. High reversal rate;
2. Lack of predictability of outcomes — something that decreases settlement and frustrates lower courts;
3. The disregard of time spent by district court judges in understanding the evidence and patent information;
4. The mind-numbing minutia of claim construction decisions faced by the court in “nearly every patent case.”

Claim construction, although similar to statutory construction is different for many reasons and is intertwined with facts that make the foundation for de novo review questionable. The arguments of CJ Michel are further highlighted by Judge Newman’s dissent.

J Newman focuses on how scientific and technological evidence serve as the backdrop for any claim construction and how claim construction should focus on the invention rather than following formalistic requirements that trip over every statement in a patent application. Finally, Newman argues that a Daubert framework is more appropriate for claim construction.

The Federal Circuit's position that patent interpretation requires more rigorous appellate review than other fact/law issues has not well withstood the test of experience. It is time to reopen the question and to rethink, en banc, the optimum approach to accuracy, consistency, and predictability in the resolution of patent disputes, with due attention to judicial structure, litigants' needs, and the national interest in invention and innovation. (Newman dissenting).

Judge Rader agreed with both CJ Michel and J Newman, but filed his own opinion. Rader gave some legal basis for reviewing Cybor — noting the Supreme Court’s opinion that claim construction "falls somewhere between a pristine legal standard and a simple historical fact." (Markman). Rader maintained his long-standing position that district courts should be given deference because they are better versed in the facts and the issues.

“Trial judges can spend hundreds of hours reading and rereading all kinds of source material, receiving tutorials on technology from leading scientists, formally questioning technical experts and testing their understanding against that of various experts, examining on site the operation of the principles of the claimed invention, and deliberating over the meaning of the claim language. If district judges are not satisfied with the proofs proffered by the parties, they are not bound to a prepared record but may compel additional presentations or even employ their own court-appointed expert." (Rader dissenting in Cybor).

Judge Moore: In what appears to be her first patent opinion, New CAFC Judge Moore also set her target on Cybor — stating that the court should “reconsider its position on deference.” 

Judges Gajarsa, Linn, and Dyk all concurred with the decision not to rehear this particular case, but noted that “In an appropriate case we would be willing to reconsider limited aspects of the Cybor decision.”  In particular, those three judges appear to believe that de novo is still appropriate when the intrinsic evidence (written description and prosecution history) on its face resolves “the question of claim interpretation.”

SUPREME COURT NEXT: This leaves us in the situation where at least eight of the twelve Federal Circuit judges believe that Cybor should be revisited if an “appropriate case” arises. This fractured decision is also ripe for Supreme Court review, and along with the Tamoxifen antitrust cases, are the two most likely to be granted certiorari in 2007.

Details: Judges Michel, Newman, Rader, Mayer, and Moore have all bluntly criticized Cybor. Judges Gajarsa, Linn, and Dyk have a more limited criticism.

KSR v. Teleflex (Supreme Court 2006).

Section 103 of the Patent Act focuses on “differences between the subject matter sought to be patented and the prior art.”  In the 1976 Sakraida case, the Supreme Court held that simply aggregating old elements together does not pass the patentability test if the elements are each performing the same functions that they were already known to perform.

The “mere aggregation” test of Sakraida, however, has not been followed by the Court of Appeals for the Federal Circuit (CAFC). Instead, the CAFC’s approach has allowed mere aggregations to be patented so long as there is no evidence suggesting that the elements be combined.

The pending case of KSR v. Teleflex squarely addresses this debate. KSR recently filed reply brief closes the written arguments in this landmark case, and oral arguments are scheduled for November 28, 2006.

KSR’s attorneys, including GWU Professor John Duffy, argue strongly that 103(a) has been wrongly interpreted as merely a way to challenge patentability rather than a “condition of patentability” as the section is titled. Under the current suggestion test, claims “cannot be held invalid . . . no matter how trivial might be the differences” from the prior art unless evidence suggesting the difference is found in the art.  As noted by Hal Wegner, the Court’s reaction to this argument could shift the strong presumptions of non-obviousness.

KSR has gone beyond its attack on the Federal Circuit suggestion/teaching/motivation test and raised as a further issue the point that it should win under a preponderance of the evidence standard for challenging patent validity.

In the process, KSR takes a shot at the AIPLA’s “balanced” position.

It is by no means clear why patent bar groups would have a systematic interest in a “balanced” standard of patentability, in view of the enormous fees that litigation of invalid patent claims can generate.
