Judge Andrews finds preamble limiting.

Judge Richard G. Andrews recently construed claims related to LCD technology.  MiiCs & Partners Am., Inc. v. Toshiba Corp., C.A. No. 14-803-RGA (D. Del. Aug. 31, 2016).  Of note, Judge Andrews found that the preamble of three claims “carries patentable weight and is limiting to the claimed ‘liquid crystal display apparatus.’”  Id. at 16.  The Court explained, after considering the title (“Liquid Crystal Display Apparatus and Method for Lighting Backlight Thereof”), abstract (beginning: “In the liquid crystal display, . . .), and specification (describing the invention and its embodiments as “a liquid crystal display apparatus” fifteen times), “it is inconceivable that a reader would come away with anything but a firm conviction that the inventor invented and intended the claims to encompass a liquid crystal display apparatus, rather than some vague combination of two backlights.”  Id. at 17-18.
