Notable Federal Circuit Opinions from Last Week

Transcore, LP v. Elec. Transaction Consultants Corp., No. 2008-1430 (Fed. Cir. Apr. 8, 2009):

Holding: An unconditional covenant not to sue authorizes sales by the covenantee for purposes of patent exhaustion.

Comments: According to the Federal Circuit, a covenant not to sue is essentially a nonexclusive patent license.

Takeda Pharm. Co. v. Doll, No. 2008-1131 (Fed. Cir. Apr. 10, 2009):

Holding: For purposes of double patenting analysis, the relevant time frame for determining whether a product and process are “patentably distinct” should be at the filing date of the secondary application.
