SRAM v. AD-II Engineering

decided on October 2, 2006 by the Court of Appeals for the Federal Circuit

In SRAM v. AD-II Engineering, the Court of Appeals for the Federal Circuit overturned a claim construction offered by the district court on the grounds that the court had improperly read a limitation into the claim. The specification of the patent and the prosecution history supported the construction offered by the CAFC, and the mentioning of the would-be limitation as an “aspect of the invention” was of no matter.
