This week the blog will publish a multi-part online symposium on United States v. Texas, a challenge by Texas and twenty-five states to the Obama administration's deferred-action policy for immigration. Contributions to this special feature, as well as an “explainer” by this blog's Lyle Denniston, are available here.

Mylan Inc. v. Daiichi Sankyo Co., Ltd.

Petition for certiorari denied on March 21, 2011
Docket No. Op. Below Argument Opinion Vote Author Term
10-770 Federal Cir. N/A N/A N/A N/A OT 2010

Issue: Whether, contrary to this Court's decision in KSR International Co. v. Teleflex Inc., the Federal Circuit has erred in applying a “lead compound test” as the exclusive standard for determining whether a patent claim directed to a new chemical compound is “obvious” and therefore invalid under 35 U.S.C. § 103(a).
