Lighting Ballast Control LLC v. Philips Elec. N. Am. Corp., 2012-1014 (Jan. 2, 2013) (non-precedential) Patent No. 5,436,529

Key point:

• A claim that associates the words “means” or “means for” with a function is a means-plus-function claim under 35 U.S.C. § 112, ¶ 6, and absence of corresponding structure in the specification makes such a claim indefinite.
