Outline I. Williamson sets the standard II. Review of the recent decisions and how the courts have applied Williamson in the electrical and mechanical arts III.PTO Guidance IV.Best practices for leveraging §112(f) and functional claims for maximum patent protection 5
What is functional claiming? 35 U.S.C. § 112(f) (formerly 112(6): ELEMENT IN CLAIM FOR A COMBINATION. — An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. 6
Williamson v. Citrix Online, LLC , 792 F.3d 1339 (Fed. Cir. 2015) ( en banc ) Claim 8. A system for conducting distributed learning among a plurality of computer systems coupled to a network, the system comprising: … a distributed learning control module for receiving communications a distributed learning control module for receiving communications transmitted between the presenter and the audience member computer systems and for relaying the communications to an intended receiving computer system and for coordinating the operation of the streaming data module 7
Williamson (cont’d) District Court: Invalid for Indefiniteness. “Distributed learning control module,” was a means -plus-function term. Specification failed to disclose the necessary algorithms for performing all of the claimed functions. Federal Circuit: Affirmed. “To determine whether § 112, para. 6 applies to a claim limitation, our precedent has long recognized the importance of the presence or absence of the word “means.” …the use of the word “means” in a claim element creates a rebuttable presumption that § 112, para. 6 applies. 8
Williamson (cont’d) Federal Circuit Quotes: Claim “replaces the term ‘means’ with the term ‘module’ and recites three functions performed by the ‘distributed learning control module.’” ’Module’ is a well -known nonce word that can operate as a substitute for ‘means’ in the context of § 112, para. 6. …Here, the word ‘module’ does not provide any indication of structure because it sets forth the same black box recitation of structure for providing the same specified function as if the term ‘means’ had been used. Prefix ‘distributed learning control’ does not impart structure into the term ‘module,’ nor does written description impart any structural significance to the term. 9
Williamson (cont’d) “Where there are multiple claimed functions, the patentee must disclose adequate corresponding structure to perform all of the claimed functions.” “Structure disclosed in the specification qualifies as “corresponding structure” if the intrinsic evidence clearly links or associates that structure to the function recited in the claim.” “Even if the specification discloses corresponding structure, the disclosure must be of “adequate” corresponding structure to achieve the claimed function.” 10
Williamson (cont’d) If a person of ordinary skill in the art would be unable to recognize the structure in the specification and associate it with the corresponding function in the claim, a means- plus- function clause is indefinite.” “The specification does not set forth an algorithm for performing the claimed functions.” Newman dissent – adds uncertainty 11

District Court Cases after Williamson 14
How is Williamson being applied by District Courts After Williamson , courts determine if a claim limitation is in a format consistent with traditional means-plus-function (MPF) claim limitations. > Does the claim limitation provide or impart any structure to the claimed function being performed. Once the court establishes that a claim term is drafted in MPF format, construction of the term is the traditional two-step process. Not Dead Yet Mfg. V. Pride Solutions, LLC , 2015 U.S. Dist. LEXIS 135629 (N.D. ILL. Oct. 5, 2015). First, the court identifies the claimed function. > Second, the court determines what structure, if any, disclosed in the > specification corresponds to the claimed function. 15
“Mechanism” Invokes 112(f) MIT v. Abacus, 462 F.3d 1344 (Fed. Cir. 2006) A system for reproducing a color original in a medium using a selected multiplicity of reproduction colorants, the system comprising in serial order: a scanner for producing from said color original a set of three tristimulus appearance signals dependent on the colors in said original; display means connected to the scanner for receiving the appearance signals and aesthetic correction circuitry for interactively introducing aesthetically desired alterations into said appearance signals to produce modified appearance signals; and colorant selection mechanism for receiving said modified appearance signals and for selecting corresponding reproduction signals representing values of said reproducing colorants to produce in said medium a colorimetrically- matched reproduction. 16
