§102 §Other
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.

(column 7, lines 13 to column 18, lines 2) Regarding Claim 8, Aharoni Rami et al discloses (Fig. 1-Fig. 4) wherein gamuts corresponding to the first set of spectral characteristics and the second set of spectral characteristics together with the waveguide arrangement comprise a Region of Interest, ROI, representing full color images. (column 7, lines 43 to column 8, line 2 to column 8, line 2) Regarding Claim 9, Aharoni Rami et al discloses (Fig. 1-Fig. 4) wherein the first and the second sets of distinct spectral characteristics comprise the same white point of interest. (column 7, lines 43 to column 8, line 2 to column 8, line 2) Regarding Claim 10, Aharoni Rami et al discloses (Fig. 10) wherein the optical waveguide arrangement is arranged to provide the waveguide- based display as a head-mounted display. Regarding Claim 11, Aharoni Rami et al discloses (Fig. 10) A head-mounted display or a head-up display comprising an optical waveguide arrangement according to any of the preceding claim 1. Regarding Claim 12, Aharoni Rami et al discloses (Fig. 1-Fig. 4) A method for an optical waveguide arrangement, comprising: transmitting, by at least one light source (4301,2,3), light signals to one optical waveguide of an optical waveguide arrangement; receiving, by said one optical waveguide, the light signals from the at least one light source and conveying the light signals to a human eye, to generate a waveguide-based display (column 8, lines 27-35); and generating, by said one optical waveguide, a first image at a first focal plane of the optical waveguide arrangement when at least some of the received light signals have a set of first spectral characteristics(column 6, lines 9-14,42-52, column 8, lines 3-35) and a second image at a second focal plane of the optical waveguide arrangement when at least some of the received light signals have a set of second spectral characteristics, at least one spectral characteristic of the set of first spectral characteristics being different compared to the set of second spectral characteristics (column 6, lines 9-14,42-63, column 8, lines 3-35).
