Ibormeith IP, LLC v Mercedes-Benz USA, LLC
By Aditya Gupta – Edited by Kathleen McGuinness
Ibormeith IP, LLC v. Mercedes-Benz USA, LLC, No. 13- 1007 (Fed. Cir. October 22, 2013)
The United States Court of Appeals for the Federal Circuit affirmed a decision of the United States District Court for the District of New Jersey, which had held on summary judgment that certain means-plus-function claims of Ibormeith IP, LLC’s (“Ibormeith”) US Patent No. 6,313,749 (“the ’749 Patent”) – “Sleepiness Detection for Vehicle Driver or Machine Operator” – were invalid for indefiniteness under 35 U.S.C. § 112. Ibormeith IP, slip op. at 2.
The Federal Circuit held that the claim element “computational means” expressed a means for performing a specified function and thus was subject to the requirements of 35 U.S.C. § 112(f), which governs such means-plus-function elements. Id. at 2-3. According to the court, the ‘749 Patent failed to comply with 35 U.S.C. § 112(f) because it failed to adequately define the structure for the “computational means” limitation in the specification. Id. at 7. In so holding, the court noted that Ibormeith’s arguments regarding the breadth of its disclosure, for the purpose of infringement, must also be held against it as “binding admissions” for the purposes of a 35 USC §112(f) inquiry into claim validity. Id. at 10-11.
