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.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claims 1-6 and 8-13 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Gioia (US 2016/0327905).
Regarding claim 1, Gioia discloses a method for reconstructing a digital hologram for the digital hologram (Figs. 1-10, [0049], “reconstruction of an image of the sequence, with the help of the decoded coefficients comprising, for a selected coefficient, said index and said value.”) to be displayed by a display device ([0052], “transmitting the reconstructed image to said display device.”), the digital hologram being represented by a set of coefficients respectively associated with a plurality of definition wavelets ([0019], “obtain beforehand items of information representative of the wavelet basis which is used for the decomposition of the holographic image”), each of the definition wavelets being defined by a tuple of coordinates in a multidimensional space ([0102], “a representation of each image in the form of a set of N Gabor wavelet coefficients, {C.sub.i, σ, θ}.sub.m.”), the method comprising:

Regarding claim 4, Gioia further discloses wherein said transformation is determined based on a first data item representative of a construction characteristic of the display device ([0087], “value of the parameter a, for a given frequency f.sub.i and a given angular dispersion … with λ wavelength whose value lies between 400 nm and 780 nm.”, examiner interprets parameter a to be characteristic of the display device since it depends upon a wavelength emitted by said display) and a second data item representative of a position or direction characteristic of the display device ([0106], “the items of information relating to the location of the observers therefore comprise at least the coordinates”, examiner interprets this to mean a relative location of the display with respect to the observers).

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.
Claims 7 and 14 are rejected under 35 U.S.C. 103 as being unpatentable over Gioia (US 2016/0327905) in view of Zhao (US 2020/0186838).
Regarding claim 7, Gioia discloses as is set forth in claim 1 rejection but does not specifically disclose wherein the generating the reconstructed hologram comprises scanning a binary tree having leaves that correspond to the coefficients of said set of coefficients.
However Zhao, in the same field of endeavor because both teach a reconstruction method, teaches wherein the generating the reconstructed hologram ([0212], “holographic displays”) comprises scanning a binary tree having leaves that correspond to the coefficients of said set of coefficients ([0026], “The binary tree leaf nodes are called coding units (CUs), and that segmentation is used for prediction and transform processing without any further partitioning”, examiner interprets the CUs to correspond to the coefficients).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the instant invention to have the method for reconstructing a digital hologram of Gioia with the wherein the generating the reconstructed hologram comprises scanning a binary tree having leaves that correspond to the coefficients of said set of coefficients as taught by Zhao, for the purpose of providing increased flexibility to the coding units ([0026]).
Regarding claim 14, Gioia discloses as is set forth in claim 2 rejection but does not specifically disclose wherein the generating the reconstructed hologram comprises scanning a binary tree having leaves that correspond to the coefficients of said set of coefficients.
However Zhao, in the same field of endeavor because both teach a reconstruction method, teaches wherein the generating the reconstructed hologram ([0212], “holographic displays”) comprises scanning a binary tree having leaves that correspond to the coefficients of said set of coefficients ([0026], “The binary tree leaf nodes are called coding units (CUs), and that segmentation is used for prediction and transform processing without any further partitioning”, examiner interprets the CUs to correspond to the coefficients).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the instant invention to have the method for reconstructing a digital hologram of Gioia with the wherein the generating the reconstructed hologram comprises scanning a binary tree having leaves that correspond to the coefficients of said set of coefficients as taught by Zhao, for the purpose of providing increased flexibility to the coding units ([0026]).
