`
`Status of Claims
`
`No claim amendments are entered in this Response to Office Action. Thus, the status
`
`of the claims remain as set forth in the Preliminary Amendment of October 30, 2018. Claims
`
`21—98 are presently pending.
`
`Claim Rejections - 35 USC § 112
`
`Claims 21, 76, 92, and all of their dependent claims stand rejected as allegedly
`
`indefinite under 35 U.S.C. § ll2(b) (pre—AIA). Specifically, the examiner alleges that the
`
`phrase “A polarization conversion system operable to direct time—sequential left and right
`
`stereo images onto an overlapping area of a cinema projection screen” does not comply with
`
`the written description requirement.
`
`First, Applicants assume that the examiner’s concern relates primarily to the “time—
`
`sequential left and right stereo images” portion of this, as the “overlapping area” can be quite
`
`simply seen through a word search of the specification and an examination of figures
`
`referenced in those portions of the specification. See e. g., para. 29 and accompanying figure
`
`reproduced below for convenience:
`
`{0029} With reference. to Figures '3 and 3, the image. from bundles A’, B”, and C" should
`
`substantially overlap the image from bundles A, B, and C for viewing comfort (although
`
`perfect: overlap is not necessarily required}.

`location relative to the other include (I) using thumb screws or a similar mechanical

`
`
`
`
`
`As described and shown, image bundles from the two light paths are substantially overlapped
`
`on a cinema projection screen and are specifically described as an “overlap.”
`
`While the exact phrase “time—sequential left and right stereo images” is not found in the
`
`specification, the written description and figures clearly show this aspect of the claims.
`
`Specifically, the above figures show both the light paths (A—B—C and A’—B’—C’) having
`
`synchronized “alternate frames.” “Frames” are a well—known term of art in the video field as
`
`video images are projected at a certain “frames per second” rate, with the typical cinema
`
`PIOJ'ectiOH frame rate of 60 fps. See it.t.£12.s.2.41/3:at.£2112£223£24133:gram}.liizfiiramem‘szgte. For 3D
`
`cinema, this frame rate is commonly more than doubled to 144 fps ——
`
`.it.iflfiéififliiéflfiiEIIJEEGL.hS?.§~.’.v.’.Szit.é£13.12Qt‘.§~§;fé.~.§£§illitffiirllé‘lfizflfiflim, The important Point here is not the
`
`particular frame rate, but that the frames are well—understood to be a time—sequential
`
`presentation of static images that, due to the biology of a human’s optic system, appears to a
`
`viewer to be “moving pictures.”
`
`21
`
`
`
`So from the above image, it is shown that there are alternating frames of differing
`
`polarizations, with conventional schematic elements showing vertical and horizontal linearly
`
`polarized light — although it should be clear that the claims are not limited to a particular type
`
`of polarization being used to encode the 3D images —and for convenience that schematic
`
`portion of Fig. 2 as an example is highlighted below:
`
`
`
`So the above illustrates that there are alternating polarizations for each sequential cinema
`
`video frame — one polarization for the left eye image and another polarization for the right
`
`eye image. This latter principle of using one polarization for a left—eye image and one
`
`polarization for a right—eye image is described in the background of the present application
`
`as, for example, shown below from Para. 4 of the present application:
`
`than. ha}? of the originai fiux, tiRSS resuitiug in a dimmer final image. The poiafizafion

`
`By gii‘eses‘itiug diffs-rem images in each eye, 3}} imagery can ht:
`

`
`22
`
`
`
`Based on the above, the phrase “time—sequential left and right stereo images onto an
`
`overlapping area of a cinema projection screen is clearly supported in the original disclosure
`
`in connection with 35 U.S.C. 112(a), and accordingly the rejection of claims 21—98 under this
`
`subsection is overcome.
`
`Based on this same language, the examiner has rejected claims 21—98 under 35 U.S.C. 112(b)
`
`as being allegedly indefinite for failing to particularly point out and distinctly claim the
`
`subject matter which the inventor or a joint inventor regards as the invention. Applicants
`
`trust that the above careful explanation explain how the time—sequential left and right stereo
`
`images are employed in the claimed subject matter. Specifically, the left and right stereo
`
`images may be time—sequentially—encoded on alternating frames (as an example) as
`
`illustrated in the above image of Figure 2. Regarding the limitation of “diverging image
`
`light,” one of ordinary skill in the art understands that light emitted from a projection lens
`
`toward a projection screen is a diverging image light, as the projection lens is a convex lens
`
`that is designed to project an image onto a large projection screen. This diverging light is
`
`understood to be contrasted from converging light or collimated light. The diverging light is
`
`clearly illustrated above as an example in Figure 2, and the scope of the claims is clearly
`
`understood based upon this background and description.
