Heading: Step (d) – Zooming

Text: The district court construed step (d), “zooming in on the first area of the displayed map to about the boundaries of the first area to display a higher level of detail than the displayed map” to mean: causing the computer to display closer up and with more detail perceptible only the area en- closed by the actual boundaries of the first area selection cursor, or an area largely, but not ex- actly equal to the area enclosed by the actual boundaries of the first area selection cursor, so that the display appears to have zoomed down closer to earth. J.A. 16. In construing step (d), the district court characterized the step as being equivalent to a disputed phrase from the ’576 patent, “[z]ooming said displayed map to substantially coincide with the boundaries of said cursor, thereby displaying a higher level of detail,” and assigned a similar definition. J.A. 13-14, 16. 11 MOVE INC v. REAL ESTATE ALLIANCE First, we agree with REAL that the district court erred by importing the first area selection cursor expressly recited in the ’576 patent claim into its construction of this claim. REAL also asserts that, because the district court’s construction of a similar zooming step in the ’576 patent excludes “the mere use of optical magnification,” J.A. 12, the zooming step in this claim should have a similar exclusion. Move responds that the district court construction already requires more detail to be perceptible, thus the express exclusion proposed by REAL is unnecessary. This step recites “zooming . . . to display a higher level of detail.” Thus, this step expressly requires more detail to be displayed. According to the plain language of this claim, mere magnification is not enough as it would not “display a higher level of detail.” Moreover, during prosecution of the ’576 patent, the inventor distinguished a similar zooming step from a prior art analog projection system that optically magnifies static map slides. According to the inventor, the prior art optical magnification system “fails to provide a greater level of detail.” J.A. 10. We conclude that the zooming step requires the computer to enlarge and display with more detail than was displayed in step b) an area equal to or approximately equal to the first area.
