Functional Claiming for Mechanical and Electrical Arts

Description

In Williamson v. Citrix Online LLC, the Federal Circuit issued a decision relating to means-plus-function claims. This decision has had a dramatic impact on interpreting functional claim terms, regardless of whether construing claim language in prosecution, post-grant challenges at the PTAB, or district court litigation.

Patent law permits functional claiming in Section 112(f). The applicant must provide sufficient structure in the specification to perform any functional limitations. Since Williamson, patentees must meet a heightened standard of review by sufficiently disclosing the functional basis for patents in the electrical or mechanical arts.

Patent owners and their counsel must account for the heightened standards when drafting applications.
