Kesatoshi.” Further, on page 9 of the answer the examiner argues that Reddy
teaches counting horizontal pixels and number of vertical lines “[s]ee column 9,
lines 13-26 of Reddy for counting HSYNC lines to determine the active vertical
resolution and col. 9, lines 28-41 for counting clock signals to determine the
active horizontal resolution.”
We disagree with the examiner’s assessment of the scope of the claims
and teaching of the references. We agree with the appellants’ statement that the
claims require determining both the variable active horizontal and vertical
resolution by counting in different ways. We find that the scope of independent
claims 1, 11, 21, 31 and 37, includes determining the variable active resolution
by determining the active horizontal resolution by either counting a pixel clock or
valid pixels and by determining the active vertical resolution by using a counter.
This limitation is shown in claims 1 and 31 by the steps of “determining the
variable active horizontal resolution” and “determining the variable active vertical
resolution.” This limitation is shown in claims 11, 21 and 37 by the “horizontal
counter coupled to the display controller output “ and the “vertical counter
coupled to the display controller output.”
We do not find, as the examiner asserts on page 7 of the answer, that the
counting to determine frequency teaching of Kesatoshi meets the claim limitation
