Supreme Court Establishes New Rule § A patent is invalid for indefiniteness if its claims, read in light of the specification delineating the patent, and the prosecution history, fail to inform, with reasonable certainty, those skilled in the art about the scope of the invention 9 © AIPLA 2015
Supreme Court Reaffirms Principles § Definiteness is to be evaluated from the perspective of a person skilled in the relevant art § Claims are to be read in light of the patent’s specification and prosecution history § Definiteness is to be measured as of the time of the patent application 10 © AIPLA 2015
Biosig Instruments, Inc. v. Nautilus, Inc. 783 F. 3 d 1374 (April 27, 2015) 11 © AIPLA 2015

Williamson v. Citrix Online, LLC, 792 F. 3 d 1339 (June 16, 2015) Claims recite “distributed learning control module” Question 1: Does 35 U. S. C. § 112, para. 6 [now 112(f)] apply? § Court held yes 23 © AIPLA 2015

35 U. S. C. § 112(f) 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. 25 © AIPLA 2015
Now Williamson holds § No longer strong presumption that 112(f) does not apply when the word “means” is not used § The standard is whether the words of the claim are understood by persons of ordinary skill in the art to have a sufficiently definite meaning as the name for structure. 26 © AIPLA 2015
Now Williamson holds § When a claim term lacks the word “means, ” the presumption can be overcome and 112(f) applies if the challenger demonstrates that the claim term fails to “recite sufficiently definite structure” or else recites “function without reciting sufficient structure for performing the function. ” 27 © AIPLA 2015
