Office Action

§102 §103
DETAILED ACTION 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 . Drawings The drawings are objected to as failing to comply with 37 CFR 1.84(p)(4) because the specification refers to system 100 for drawing 1, however, the object in drawing 1 annotates item 300 as the system and not 100. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 1-7 is/are rejected under 35 U.S.C. 103 as being unpatentable over Siddharth (SG-195397-A1), in view of Kuo (US-8212744-B2). Siddharth teaches: In regards to claim 1, Siddharth teaches a system, comprising: (abstract) a projection surface comprising: (fig(s) 3-5, pg(s) 3-5, ‘teaches a ‘opacity layer’, ‘privacy layer’, and a ‘base layer’) a first layer comprising a material that prevents reflection of light, (line 5 page 4, ‘rigidity layer made of glass, poly carbonate or acrylic.’; fig(s) 3-5, ‘base layer’) a second layer comprising a transparent image forming material, and (page 5; ‘ recites in the second layer a film may be provided up to 99% reduction of UV light transmission.; ‘polyester layer’’) a third layer comprising a privacy screen filter, (‘the invention comprises a ‘privacy layer shown in figure 3.’) wherein the second layer is provided between the first layer and the third layer; and (fig(s) 3-5, ‘comprises a second layer or more as shown in fig. 4 as known to those in the art and disclosed in the specification these layers may be interchanged or placed according to function and needed configuration.’) a light source configured to emit light on the projection surface to create an image on the projection surface, (14 fig(s) 1-2, ‘show a front and rear projection screen orientation’) wherein the light source faces the first layer, (14 fig. 1) wherein the third layer causes the projection surface to appear translucent from a viewpoint of the light source emitting the light at the projection angle. (fig(s) 3-5, ‘opacity layer’; page 4, ‘the layer can vary the intensity of transmitted light passing though it.’) It would have been obvious before the effective filing date of the invention for Siddharth to provide a system to display 3D images or video to provide volumetric illusion of objects which is selectively operable to display props, objects, images or video. Siddharth does not teach: wherein the light is emitted at a projection angle on the projection surface, and Kuo teaches: wherein the light is emitted at a projection angle on the projection surface, and (118 fig. 2, ‘shows and image source projected at an angle to a see-through screen 102 for a rear projection screen which can be implemented in a front projection screen therefore it is known in the art.’) It would have been obvious before the effective filing date of the invention for Kuo to provide an angle light projection source for a system to display 3D images or video to provide volumetric illusion of objects which is selectively operable to display props, objects, images or video.
