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 .
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.
Claim(s) 1-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Limon et al. (Patent App. Pub. No. EP 3 405 767 A1).
Regarding claims 1, 14 and 19, Limon et al. shows in Figs. 1-7 a system (100) comprising memory (194) and one or more processors at a device (102, i.e., computing device) coupled to the memory, a single light source (722) arrangement of light sources, and an image sensor (718): producing a pattern of light using the single light source arrangement of light sources; detecting reflections in an image obtained via the image sensor (718), the reflections corresponding to light from each of a plurality of the light sources reflecting from a surface of an attachable lens (710); and determining a lens characteristic of the attachable lens based on the detected reflections and a 3D spatial relationship between the image sensor and the light sources (claim 1, [0365] – [0366]). Limon et al. is silent that the device uses an arrangement of light sources instead of a single light source. Arnoult et al. shows in Fig. 1 a pattern (21) of light using an arrangement of light sources (20). Therefore, it would have been obvious to one of ordinary skill in the art to provide an arrangement of light sources of Arnoult et al. on the device of Limon et al. in order to measure a larger surface region (see claims 1 & 12).
Regarding claims 2 and 15, Limon et al. shows in Figs. 1-7 the method of claim 1 and the system of claim 14, wherein the lens characteristic is a diopter of the attachable lens ([00182]).
Regarding claims 3 and 16, Limon et al. shows in Figs. 1-7 the method of claim 1 and the system of claim 14, wherein the lens characteristic is the position of the attachable lens ([00249]).
Regarding claims 4 and 17, Limon et al. shows in Figs. 1-7 the method of claim 1 and the system of claim 14, wherein the lens characteristic is a presence of the attachable lens ([00249]).
Regarding claim 5, Limon et al. shows in Figs. 1-7 the method of claim 1, wherein determining the lens characteristic comprises assigning pairs of reflections in multiple images obtained via the image sensor to an individual light source of the light sources.
Regarding claims 6-9, 18 and 20, Limon et al. shows in Figs. 1-7 the method of claim 1, the system of claim 14, and the non-transitory computer-readable storage medium of claim 19, wherein determining the lens characteristic comprises assigning a first pair of reflections and a second pair of reflections in images obtained via the image sensor to a first light source and a second light source, respectively, of the light sources.
Regarding claim 10, Limon et al. shows in Figs. 1-7 the method of claim 1, wherein the detected reflections in the image include a static reflection corresponding to light from at least one of the light sources reflecting from a surface of an additional optical component in the electronic device.
Regarding claim 11, Limon et al. shows in Figs. 1-7 the method of claim 1, wherein at least one of the light sources and the image sensor are used for gaze tracking of a user of the electronic device.
Regarding claim 12, Limon et al. shows in Figs. 1-7 the method of claim 1, wherein the lens characteristic is determined via a machine learning model.
Regarding claim 13, Limon et al. shows in Figs. 1-7 the method of claim 1, wherein the attachable lens is a corrective lens ([00003]).
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure:
Brown (Patent App. Pub. No. US 2018/0164535 A1) discloses a light pattern based on light reflected from a retina of an eye and includes an array of spots.
Rathi et al. (Patent App. Pub. No. US 2023/0417627 A1) discloses determining the one or more lens characteristics of the first attachable lens can including producing a pattern of light using an arrangement of light sources.
