Verifying what was already suspected to be the case “does not give rise to a patentable invention”

The Federal Circuit yesterday issued a split opinion dealing with contributory infringement and post-KSR obviousness.

Federal Circuit: test for obviousness of structurally similar compounds is unchanged post-KSR

At the Federal Circuit, it appears that everything old is new again. In a case applying the new obviousness framework from KSR to structurally similar chemical compounds, the court affirmed a district court decision that claimed compounds would not have been obvious in light of the prior art. The court lauded the district court's "extensive […]

Post-KSR: Expert testimony enough for infringer to avoid summary judgment of no invalidity?

In a nonprecedential ruling yesterday, the Federal Circuit reversed a district court's grant of summary judgment of no obviousness.

Australia’s High Court weighs in on obviousness

There is a good post over at the Patent Prospector about a decision by the High Court of Australia (the equivalent to the U.S. Supreme Court) regarding the issue of obviousness in patent law.

Federal Circuit cites KSR, but not for the new obviousness standard

In a nonprecedential opinion released today, the Federal Circuit cited the Supreme Court's Monday decision in KSR for the first time.

After an initial reading of the opinion in KSR Int'l Co. v. Teleflex Inc., several issues jump out.

Supreme Court reverses both KSR and Microsoft

As reported at SCOTUS Blog, the Supreme Court has today ruled in two cases, reversing decisions of the Federal Circuit. The first came in KSR v.
