In a patent infringement case involving an apparatus for reading optical discs in a computer that reduces the role of magnetic disc drives, summary judgment of non-infringement in favor of defendants is affirmed as plaintiff has not proffered enough evidence to permit a reasonable juror to conclude that the accused devices contain a "data transmitting means", and without clear identification of the claimed structure or its equivalent in the accused devices, plaintiff cannot survive summary judgment.
