Obviousness after KSR v Teleflex: a private practice …

The District Court employed feleflex narrow inquiry as well, though it reached the correct result nevertheless. Another what is in predictable. It reasoned 1 the state of the industry would lead inevitably to combinations of electronic sensors and adjustable pedals, 2 Rixon msr the basis for these developments, and 3 Smith taught a solution to the wire chafing problems in Rixon, namely locating the sensor on the fixed structure of the pedal.

What matters is the objective reach of the claim.

That seems to be what the Supreme Court intended. Kxr patent protection to advances that would occur in the ordinary course without real innovation retards progress and may, in the case of patents combining previously known elements, deprive prior inventions of their value or utility.

Retrieved from ” https: Important for this case are two adjustable pedals disclosed in Telefflex. Read the Text Version. The Court repudiated several bases from which the Fed. We build and create by bringing to the tangible and palpable reality around us new works based on instinct, simple telwflex, ordinary inferences, extraordinary ideas, and sometimes even genius.

Attaching the sensor teeleflex the support member allows the sensor to remain in a fixed position while the driver adjusts the pedal. The two in combination did no more than they would in separate, sequential operation. As a result, designers might have decided to design new pedals from scratch; but they also would have had reason to make pre-existing pedals work with the new engines.


When a work is available in one field of endeavor, design incentives and other market forces can prompt variations of it, either in the same field or a different one.

In practice, few patents have been granted or defended solely on the basis that evidence showed an obviousness to try and not obviousness per se, and the impact of KSR on this point is therefore limited.

It is also unclear whether the current argument was raised before the Court of Appeals, where Teleflex advanced the nonspecific, conclusory contention that combining Asano with a sensor would not satisfy the limitations of claim 4.

Rather, the court held, the District Court was obliged first to presume that the issued patent was valid and then to render its own independent judgment of obviousness based on a review of the prior art.

In a cable-actuated throttle control the rotation caused by pushing down the pedal pulls a cable, which in turn pulls open valves in the carburetor or fuel injection unit.

Conclusion KSR helps clarify important aspects of obviousness law but does not, as some have suggested, signal a dramatic shift in the way U.

Teleflex later abandoned its claims regarding the other patents and dedicated the patents to the public. The ultimate judgment of obviousness is a legal determination.

The Rixon pedal was known to suffer from wire chafing when the pedal was depressed and released. There telerlex no necessary inconsistency between the idea underlying the TSM test and the Graham analysis. As did the District Court, we telefpex little difference between the teachings of Asano and Smith and the adjustable electronic pedal disclosed in claim 4 of the Engelgau patent.


In the years since the Court of Customs and Patent Appeals set forth the essence of the TSM test, telefled Court of Appeals no doubt has applied the test in accord with these principles in many cases. The Kwr Court was correct to conclude that, as of the time Engelgau designed the subject matter in claim 4, it was obvious to a person of ordinary skill to combine Asano with a etleflex pedal position sensor. The proper question to have asked was whether a pedal designer of ordinary skill, facing the wide range of needs created by developments in the field of endeavor, would have seen a benefit to upgrading Asano with a sensor.

In these cases patent applicants may find it necessary to present evidence, perhaps including expert opinion, to show technological distinctions, unexpected results, long-felt unsolved need, commercial success, and the like, and the added evidentiary showings may in turn result in significantly increased prosecution expense.

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 telefoex known problem for which there was an obvious solution encompassed by the patent’s claims.

This argument was not, however, raised before the District Court. Comments of Professor Gregory Mandel and discussion. We return to sensors.

This part is not new, but carriesadded weight when voiced for the first time predictable. Some showing the prior art teaches away from aof the announced standards arguably combination. KSR provided convincing evidence that mounting a modular 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. Another more subtle argumentone would expect from such an emerges from a close reading of KSR:
