Clear & Convincing: Supreme Court Affirms CAFC in Microsoft v. i4i

icrosoft wanted to see that changed, with prior art not considered by the Patent Office requiring a lower evidentiary threshold to invalidate. To rule in Microsoft’s favor would have required the Supreme Court to throw away 30 years of well-settled Federal Circuit law, as well as overruling Supreme Court precedent in effect since at least 1934, but which traces back in some form from that date a further 100 years. That was a bridge too far for the Supreme Court, who ruled today 9-0 (with concurring opinions but no dissents) that in order to invalidate patent claims 35 U.S.C. 282 requires clear and convincing evidence regardless of whether the prior art was known by the Patent Office during prosecution of the patent application.

Hungar would go on to say that the clear and convincing standard “makes no sense,” which nearly immediately drew the first comment from the bench with Justice Ginsburg saying that it would be difficult to say the standard makes no sense when it was supported by Justice Cardozo and Judge Rich. Ginsberg would later, in a nearly annoyed way, say “then you have to be saying that Judge Rich got it wrong…” Hungar cut off Justice Ginsburg, not typically a wise move.

Supreme Court Patent Watch: i4i Files Brief in Microsoft Case

Microsoft would like to have the standard for invalidating a patent claim lowered to a mere preponderance of the evidence standard. They say that prior art not considered by the Patent Office should not be afforded the same level of deference. I say — why not? Truthfully the standard for invalidating patent claims in court should be the same as it is when a patent is denied. The standard shouldn’t even be as low as “clear and convincing,” rather it should be “abuse of discretion.”
