Judge Andrews construes claims of patent relating to camera film
Judge Richard G. Andrews recently construed two disputed claim terms of U.S. Patent No. 5,187,512, entitled “Film Cassette Containing Pre-Exposed Film,” relating to “apparatus and processes for pre-exposing only certain portions of the frames of a film strip before the strip is exposed in a camera.” Universal Innovations, LLC v. CS Industries, Inc., et al., C.A. No. 11-501-RGA, at 2 (D. Del. Dec. 11, 2012). Judge Andrews construed the following means-plus-function terms:
“Means for defining (a) two film holding cavities and (b) an exposure frame opening located intermediate said cavities”
“Means for configuring said exposure frame opening such that the periphery of said opening corresponds with the periphery of said unexposed portion of said frame so as to prevent further exposure of said first latent image during the forming of a second latent image in the unexposed portion of said frame by image carrying light rays passing through said exposure frame opening during an exposure”
Id. at 3, 5.
