Polak teaches light-exiting surface with diffusing properties ([0026] and in claim 10 of Polak: wherein the light-transparent portion has a light-entering surface with diffusing properties, a light-exiting surface with diffusing properties);
and
wherein the light-guide body further comprises a first inclined surface (top curved inclined surface) and a second inclined surface 24a, the first inclined surface is connected to the second inclined surface, and the light-emitting portion is located on the first inclined surface.
Regarding the limitations of “microstructures formed on the light emitting surface”, Polak teaches light-exiting surface with diffusing properties ([0026] and in claim 10 Polak teaches: wherein the light-transparent portion has a light-entering surface with diffusing properties, a light-exiting surface with diffusing properties).
Further, Polak teaches:
[0027] According to another aspect, the light-transparent portion comprises microlenses and/or a structure is formed on the surface of the light-transparent portion. Examples of a structure on the surface of the light-transparent portion can be refractive microlenses, beam homogenizers, and collimators. Such a structure can be placed on the surface that faces towards the light source and/or the surface that faces the field of view. The structure can also be placed inside the body of the light-transparent portion.
Therefore, it would have been obvious to a person having ordinary skill in the art before the effective filing date of the invention to use microstructures on the light emitting surface, in order to homogenize the output light.
Polak does not teach a light-guide body and an annular rib, and the annular rib surrounds an outer surface of the light-guide body.
However, it is well known in the art to use annular protrusions formed on outer surface of bodies that are attached to another element within light emitting devices, as a locking mechanism. Erich teaches a seal (44) on an inner jacket in the lower region has an annular rib (39) which engages in a groove of the carrier body (53), Erich teaches another annular rib 38 in the top region (Fig.5) and it would have been obvious to a person having ordinary skill in the art before the effective filing date of the invention to use annular ribs on the outer surface of the light guide bodies , in order to tightly engage it to a housing.
Polak in view of Erich is silent regarding: a plurality of stands, the stands are disposed on a body surface of the light-guide body, the light- entering portion is located on the body surface.
Zhang teaches a light guide body (Fig.1) with a plurality of stands 500 disposed
on a body surface of the light-guide body, and it would have been obvious to a person
having ordinary skill in the art before the effective filing date of the invention to use the
stands as disclosed in Zhang, such that the light-entering portion is located on the body
surface, in the device of Polak in view of Erich in order to provide accuracy of location of the light guide body (see in Zhang: In the technical solution of the embodiment, through the locating column 500 can conveniently locate the light guide structure, ensuring the accuracy of
the location).
Regarding claim 18, Polak in view of Erich and Zhang teaches the soft light-guide member, further comprising a cylindrical portion and an annular rib (from the teachings of Erich), the cylindrical portion (substantial cylindrical bodies 18 in Polak, also see other embodiments of Polak with modified shapes of the light guide members as in Fig.6) is formed on the light-guide body, the light-emitting portion is located on one end of the cylindrical portion, and the annular rib surrounds an outer surface of the cylindrical portion.
Claims 9-13 are rejected under 35 U.S.C. 103 as being unpatentable over Polak in view of Zhang (CN 214041790 U, cited previously)
Regarding claim 9, Polak teaches the invention set forth in claim 4 above, but is silent regarding the soft light-guide member comprises a light-guide body and a plurality of stands, the stands are disposed on a bottom surface of the light-guide body, the light-entering portion is located on the bottom surface, the stands abut the circuit board, and a first gap is formed between the bottom surface and the circuit board.

Response to Arguments
The arguments filed by the Applicant on 8/21/26 is acknowledged, however they are not found to be persuasive.
Throughout the Remarks, for both claim 1 and claim 14, Applicant has just argued that the optical element 18, that is light transparent portion 18a AND the light blocking portion 18b are formed by injection molding. Therefore, for this reason, the light transparent portion is neither pressed nor elastically deformed by the light blocking portion 18b.
Polak discloses to the contrary, wherein: [0021] According to one embodiment, the light-transparent portion comprises, in particular is made of, an elastic material. Alternatively the light-blocking portion can comprise, in particular can be made of, an elastic material. Preferably, both the light-transparent portion and the light-blocking portion both comprise, in particular are both made of, an elastic material. Using an elastic material for the light-transparent portion and/or the light-blocking portion helps to avoid noise in the device and additionally helps to improve sealing of the device.Therefore, the previous rejection applies.
Furthermore, new matter was added to the originally claimed claim 5, and therefore 112 rejection and objection to specification apply.
