Now that the Supreme Court has issued its opinion in KSR v. Teleflex, the first reaction is what took it so long? During the past six months since oral arguments in late November, I was expecting that the Court was taking its time crafting a historical opinion that delved into the genesis and evolution of the nonobviousness doctrine since the Hotchkiss decision in 1851. The Court does mention the Hotchkiss decision and a few others, but the six month gestation has yielded a compact, thirty page decision that can be summarized with three simple F-words: formalism, functionality, and flexibility.
Though the Supreme Court’s unanimous reversal in KSR v. Teleflex, No. 04-1350, 550 U.S. ___ (2007), contains some harsh words for the Federal Circuit’s teaching, suggestion, or motivation (TSM) test, the decision itself appears to leave the TSM requirement roughly intact. Justice Kennedy’s opinion emphatically rejects an 'explicit' TSM test—one that would require explicit prior art teachings in order to combine given references in the obviousness analysis. At the same time, the decision appears to essentially recreate the 'implicit' or 'flexible' TSM test—one that would allow implicit suggestions, such as the nature of the problem, to provide the requisite motivation to combine. It is this implicit TSM requirement that represented current Federal Circuit doctrine, pursuant to several decisions published after certiorari was granted in KSR (e.g., In re Kahn, DyStar, & Alza). In fact, the Supreme Court even indicates that the Federal Circuit may have gotten it right in these post-cert cases. The KSR opinion is more a critique of the Circuit's application of the obviousness (and TSM) standard to the specific facts in KSR than a critique of the need to rigorously (and expansively) evaluate what would lead a PHOSITA to combine certain references in the obviousness analysis.
Under KSR, in order to evaluate whether a given combination was obvious, the factfinder must "determine whether there was an apparent reason to combine the known elements in the fashion claimed by the patent at issue." The Supreme Court’s "reason to combine" sounds significantly like "suggestion, teaching, or motivation to combine." It is interesting that the Court used a term as loose as “reason,” given concerns raised during oral argument about the indefiniteness of the term “motivation.” In addition, the Court requires that, "[t]o facilitate review, the analysis should be made explicit," a proposition for which the Court cites Kahn, warning that conclusory statements are not sufficient. The Court goes on to criticize rigid application of TSM, particularly relying solely on published articles and explicit content of issued patents. But, the Court notes, "In the years since the Court of Customs and Patent Appeals set forth the essence of the TSM test, the Court of Appeals no doubt has applied the test in accord with these principles in many cases. There is no necessary inconsistency between the idea underlying the TSM test and the Graham analysis." And, the Court explicitly notes that the post-cert Circuit cases were not before it: "The extent to which [DyStar and Alza] may describe an analysis more consistent with our earlier precedents and our decision here is a matter for the Court of Appeals to consider in its future cases." The opinion also clearly (appropriately in my opinion) invites greater analysis of the PHOSITA and the circumstances surrounding the PHOSITA and the pertinent technology than the Circuit has engaged in in some of its decisions.

In its unanimous decision in KSR Int’l. Co v. Teleflex Inc., No. 04-1350 (April 30, 2007), the Supreme Court expressly overruled the Court of Appeals for the Federal Circuit’s “teaching-suggestion-motivation” (“TSM”) test for finding a claimed invention obvious and reaffirmed the Court’s precedents (in light of the 1952 enactment of Section 103 and its holding in Graham v. John Deere Co. of Kansas City, 383 U.S. 1 (1966)) regarding the obviousness of patents “based on the combination of elements found in the prior art” where there the combination “does no more than yield predictable results.” Slip op. at 11-12. The Court’s decision has therefore called into question the validity of hundreds of thousands of claims in issued patents, and will likely lead to a dramatic change to the method by which the Patent Office, the courts, and the bar conduct their obviousness analyses.
Nevertheless, the Supreme Court’s opinion appears self-consciously narrow and provides little additional guidance for how to apply the Graham approach. The Court’s decision leaves unclear whether the party with the burden of proving obviousness must demonstrate that “there was an apparent reason to combine the known elements in the fashion claimed by the patent at issue,” or only that the claim at issue if patented would reflect an “advance[] that would occur in the ordinary course without real innovation[, which] retards progress and may, in the case of patents combining previously known elements, deprive inventions of their value or utility.” Slip op. at 14, 15. As the Court noted, “as progress beginning from higher levels of achievement is expected in the normal course, the results of ordinary innovation are not the subject of exclusive rights under the patent laws. Were it otherwise patents might stifle, rather than promote, the progress of useful arts.” Slip op. at 24. Although the Court recited the Constitutional language, it did not expressly hold that obviousness is a constitutional requirement. Further, the Court left to later case law any consideration of the extent to which the Court of Appeals’ more recent statements regarding the flexibility of its TSM test is consistent with Graham and the Supreme Court’s earlier precedents. Slip op. at 18.
