Claim Rejections - 35 USC § 103
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 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 1, 3-8 and 11-19 are rejected under 35 U.S.C. 103 as being unpatentable over Bailey et al. (US 2016/0327797) in view of Karner et al. (US 2021/0191132).
Regarding claim 1, Bailey discloses, a wavefront manipulator (Figs. 1-4) for an arrangement in a beam path of a head-up display (Para. 0003-0006 and see 100) between a picture generating unit (Para. 0034 and see 220, 221) and a projection surface (222), the wavefront manipulator comprising:
a holographic arrangement (230) comprising at least two holographic elements (231, 232, 233), the at least two holographic elements being arranged directly behind one another in the beam path (see 231, 232, 233) and configured to be reflective for at least one defined wavelength (Para. 0061, lines 11-35) and a defined angle of incidence range (Para. 0061, lines 11-35).
Bailey does not disclose a first holographic element of the at least two holographic elements includes at least one first hologram, wherein a second holographic element of the at least two holographic elements includes at least one second hologram, and wherein the at least one first hologram is assigned to the at least one second hologram such that light having the at least one defined wavelength and the defined angle of incidence range which is reflected at the at least one first hologram is reflected at the at least one second hologram.
Karner teaches, from the same field of endeavor that in a wavefront manipulator that it would have been desirable to make a first holographic element of the at least two holographic elements includes at least one first hologram (Para. 0018 and 0128), wherein a second holographic element of the at least two holographic elements includes at least one second hologram (Para. 0018 and 0128), and wherein the at least one first hologram is assigned to the at least one second hologram such that light having the at least one defined wavelength and the defined angle of incidence range which is reflected at the at least one first hologram is reflected at the at least one second hologram (Para. 0018 and 0128).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include a first holographic element of the at least two holographic elements includes at least one first hologram, wherein a second holographic element of the at least two holographic elements includes at least one second hologram, and wherein the at least one first hologram is assigned to the at least one second hologram such that light having the at least one defined wavelength and the defined angle of incidence range which is reflected at the at least one first hologram is reflected at the at least one second hologram as taught by the wavefront manipulator of Karner in the wavefront manipulator of Bailey since Karner teaches it is known to include these features in a wavefront manipulator for the purpose of providing a wavefront manipulator with enhanced contrast ratio and efficiency.

Regarding claim 4, Bailey in view of Karner discloses and teaches as set forth above, and Bailey further discloses, at least one of the at least two holographic elements comprises at least two holograms configured to be reflective for mutually different wavelengths (Para. 0034 and see 231, 232, 233), and/or wherein at least one of the at least two holographic elements comprises at least one hologram configured to be reflective for at least two mutually different wavelengths.
Regarding claim 5, Bailey in view of Karner discloses and teaches as set forth above, and Bailey further discloses, in relation to the arrangement of the individual holograms in relation to a defined direction, the first holographic element is arranged identically or mirror-symmetrically with respect to the second holographic element (Para. 0052-0054 and see 231, 232, 233).
Regarding claim 6, Bailey in view of Karner discloses and teaches as set forth above, and Bailey further discloses, a plurality of the holograms of at least one of the holographic elements are recorded with two design wavefronts (see 231, 232, 233), of which at least one design wavefront of at least one hologram of the holographic elements is identical to at least one design wavefront of another hologram of one of the holographic elements with regard to the wavelength and the angle of incidence (Para. 0052-0054).
Regarding claim 7, Bailey in view of Karner discloses and teaches as set forth above, and Bailey further discloses, the at least two holographic elements are arranged at a distance from one another of less than 1 millimeter (see 231, 232, 233 of Fig. 2).
Regarding claim 8, Bailey in view of Karner discloses and teaches as set forth above, and Bailey further discloses, the holographic arrangement is configured in a form of a layer or a film or a substrate or a plate and/or has a planar surface or a curved surface (see 231, 232, 233).
Regarding claim 11, Bailey in view of Karner discloses and teaches as set forth above, and Bailey further discloses, an optical component (240, 250) configured to be transmissive and to be arranged in the beam path between the holographic arrangement and the projection surface (Para. 0051).
Regarding claim 12, Bailey in view of Karner discloses and teaches as set forth above, and Bailey further discloses, the wavefront manipulator is configured to project multi-colored image representations (Para. 0052-0054).
Regarding claim 13, Bailey in view of Karner discloses and teaches as set forth above, and Bailey further discloses, at least one of the holographic elements (see 231, 232, 233) is configured efficiently for a plurality of angles of incidence and/or for a plurality of angle of incidence ranges that do not overlap one another (Para. 0061).
Regarding claim 14, Bailey in view of Karner discloses and teaches as set forth above, and Bailey further discloses, the holographic arrangement is configured in a curved fashion (see 231, 232, 233).
Regarding claim 15, Bailey in view of Karner discloses and teaches as set forth above, and Bailey further discloses, an optical arrangement for a head-up display (Para. 0003-0006 and see 100) at a projection surface (250), the head-up display including a picture generating unit (220), the optical arrangement comprising: a wavefront manipulator as claimed in claim 1 (see rejection of claim 1 above).
Regarding claim 16, Bailey in view of Karner discloses and teaches as set forth above, and Bailey further discloses, the picture generating unit comprises a plane configured to emit light in a defined emission angle range and with a defined maximum bandwidth with regard to the wavelengths of the emitted light (Para. 0051-0053 and see 231, 232, 233).
Regarding claim 17, Bailey in view of Karner discloses and teaches as set forth above, and Bailey further discloses, the picture generating unit is configured to emit laser light in at least two different wavelengths (Para. 0051 and see 221, “R”, “G”, “B”).
Regarding claim 18, Bailey in view of Karner discloses and teaches as set forth above, and Bailey further discloses, the optical arrangement has a volume of less than 10 liters (see Fig. 2).
Regarding claim 19, Bailey in view of Karner discloses and teaches as set forth above, and Bailey further discloses, a head-up display (Para. 0003-0006 and see 100) comprising: a projection surface (250), wherein the head-up display comprises an optical arrangement as claimed in claim 15 (see rejection of claim 15 above).
Claims 2 and 9-10 are rejected under 35 U.S.C. 103 as being unpatentable over Bailey et al. (US 2016/0327797) in view of Karner et al. (US 2021/0191132) as applied to claim 1 above, and further in view of Cakmakci et al. (US 2022/0163804).
Bailey in view of Karner remains as applied to claim 1 above.
Bailey in view of Karner does not disclose at least one optical element which has a freeform surface and is configured to be arranged in the beam path between the picture generating unit and the holographic arrangement.
Cakmakci teaches, from the same field of endeavor that in a head-up display (Figs. 1-3) that it would have been desirable to include at least one optical element (212, 312) which has a freeform surface (Para. 0025) and is configured to be arranged in the beam path between the picture generating unit (202) and the holographic arrangement (214-1, 214-2 and 314).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include at least one optical element which has a freeform surface and is configured to be arranged in the beam path between the picture generating unit and the holographic arrangement as taught by the head-up display of Cakmakci in the combination of Bailey in view of Karner since Cakmakci teaches it is known to include these features in a head-up display for the purpose of providing a head-up display with improved image quality, efficiency and increased field of view.
Regarding claim 9, Bailey, Karner and Cakmakci discloses and teaches as set forth above, and further teaches, from the same field of endeavor that in a head-up display that it would have been desirable to make the optical element is configured to be reflective and/or transmissive (212, 312).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include the above mentioned limitations as taught by the head-up display of Cakmakci in the combination of Bailey in view of Karner since Cakmakci teaches it is known to include these features in a head-up display for the purpose of providing a head-up display with improved image quality, efficiency and increased field of view.
Regarding claim 10, Bailey, Karner and Cakmakci discloses and teaches as set forth above, and further teaches, from the same field of endeavor that in a head-up display that it would have been desirable to make the freeform surface of the optical element is configured to at least partly correct at least one aberration (Para. 0025).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include the above mentioned limitations as taught by the head-up display of Cakmakci in the combination of Bailey in view of Karner since Cakmakci teaches it is known to include these features in a head-up display for the purpose of providing a head-up display with improved image quality, efficiency and increased field of view.
