Question presented
Whether a patentee’s statutory entitlement to “equivalents thereof” under 35 U.S.C. § 112(f) may be extinguished as a matter of law, regardless of the evidence comparing the structures as wholes, whenever the patentee does not separately account for each component of the disclosed structure or explain why any should be omitted?
