Appeal No. 2006-1930
Application No. 09/976,199
Rejection of claims 1, 3 through 7, 10, 11, and 13 through 18.
Appellants argue, on page 11 of the brief, that: “It is respectfully asserted that
neither Shen nor Yamazaki, either alone or in combination, suggests or describes
attempting to adjust (adjusting) the luminance of the OLEDs to the desired luminance,
which is a function of time.” (Emphasis original.) Specifically, appellants assert that
the “claim refers to constant luminance temporally, as the one or more OLEDs
degrades.” (Emphasis original.) Appellants argue that this is different then Shen’s device
which is concerned with calibrating the display device to provide a uniform light output
and is concerned with providing a uniform spatial light output. Appellants also assert
that Shen does not teach or suggest adjusting the actual luminance to a desired luminance
which is based on time. Appellants further argue, on page 12 of the brief, that Yamazaki
does not address temporal degradation but rather degradation due to temperature, and as
such the combination of the references do not teach the limitations of the claims.
The examiner responds on page 9 of the answer, stating that claim 1 does not
recite the “desired luminance, which is a function of time” as argued by appellants but
rather recites “having a desired luminance, as a function of time.” On page 9 of the
answer, the examiner identifies several sections of Shen which discuss the temporal
impact on luminance of the OLEDs. Further, on page 10 of the answer, the examiner
states claim 1 does not recite “constant luminance temporally” as argued by appellants,
and that while appellants’ specification may discuss such a feature, such a limitation is
not read into the claims.
We concur with the examiner’s claim construction and findings relating to Shen.
Claim 1 recites “having a desired luminance, as a function of time, for one or more
organic light emitting diodes (OLEDs) included in said emissive display” and “utilizing,
at least in part, the estimated amount of degradation, attempting to adjust the luminance
of the OLEDs to the desired luminance.” Thus, claim 1 recites that there is a desired
luminance which has a temporal component, and that this desired luminance is used in
