Summary judgment granted for Defendant, F. Finally, the court held that genuine issues of material fact precluded summary judgment.

Patents must show some kind of innovation in adding or modifying an existing element. In the end, the Supreme Court decided to establish the “Graham” standard, not the TSM standard, for testing obviousness. One of the ways in which a patent’s subject matter can be proved obvious is by noting that there existed at the time of invention a known problem for which there was an obvious solution encompassed by the patent’s claims.

In newer cars, computer-controlled throttles do not operate through force transferred from the pedal by a mechanical link, but open and close valves in response to electronic signals. Future patents will also be affected. Existing patent owners facing validity questions may want to ask if the TSM test was applied and, if not, was the correct Graham analysis from the Graham vs.

Application of the foregoing standards demonstrates that claim 4 is obvious. Thanks for using UpCounsel! Important patents needed to be evaluated under the stricter Graham standard, which demands additional evidence to overcome obviousness.

A great deal of debate sprang up in the wake of the decision, particularly over the implications on the TSM test and concepts including “obvious to try,” ” person having ordinary skill in the art ” and summary judgment. Oral arguments were heard by the Supreme Court on November 28, How does the KSR decision change patent evaluations?


United States Supreme Court case.

For example, the Yeleflex patent locates the sensor in the pedal footpad, but is known for wire chafing. You must consider prior art documentation to make sure every element in the claim is new. Federal Circuit reversed and remanded. Since krs decision, both the Federal Circuit and the Patent Office have struggled to regain objectivity.

There is no necessary inconsistency between the test and the Graham analysis. Against this background the obviousness or nonobviousness of the subject matter is determined. The USPTO management has telleflex this emphasis up with a memorandum to all technology directors instructing them that when making an obviousness rejection “it remains necessary to identify the reason why a person of ordinary skill in the art would have combined the prior art elements in the manner claimed.

A statistical study [5] noted that there was a multi-fold increase in the percentage of patents found invalid on trials both on the basis of novelty and of non-obviousness before and after the certiorari in KSR.

In general, obtaining a patent after KSR vs. Engelgau claims he invented the patent’s subject matter Feb. Existing patent owners affected by the Supreme Court’s decision may find themselves susceptible to validity challenges. The test required a challenger to show any “teaching, suggestion, or motivation” that would result in a person of ordinary skill to combine prior art as detailed in the patent. The TSM test was introduced in to reject a patent for obviousness only when teachings, suggestions, or motivation from prior art proved the patent combination’s acceptance as non-obvious.

KSR vs. Teleflex: Everything You Need to Know

In many telfflex there may be little discussion of obvious techniques or combinations, and market demand, rather than scientific literature, may often drive design trends. In Leapfrog Enterprises, Inc.

When a work is available in one field, design incentives and other market forces can prompt variations of it, either in the same field or in another. Every patent issued is presumed to be valid, and proving it invalid is a heavy burden.


The proper question was whether a pedal designer of ordinary skill in the art, facing the wide range of needs created by developments in the field, would have seen an obvious benefit to upgrading Asano with a sensor.

KSR vs. Teleflex: Everything You Need to Know

Inventors had obtained a number of patents for such sensors. Why Is KSR vs. Others say the Supreme Court ignored legislative history in the KSR decision, essentially taking a step back. KSR provided convincing evidence that mounting an available sensor on a fixed pivot point of the Asano pedal was a design step well within the grasp of a person of ordinary skill in the relevant art and that the benefit of doing so would be obvious.

This argument was not raised before the District Court, and it is unclear whether it was raised before the Federal Circuit. Previous cases the Supreme Court referred to were Hotchkiss vs.
