Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 1-8, 22-23, 26-32, and 34-36 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claim 1 recites the limitation "the side wall of the protruding portion" in line 7. There is insufficient antecedent basis for this limitation in the claim. It is unclear if “the side wall” is intended to refer to the “side surface,” the “structured area,” another element of the “protruding portion,” or an additional surface of the optical lens. As such, it is unclear what structure is required by the claims. Furthermore, it is unclear how the side wall of the protruding portion of the first lens element is offset from an optical axis of the optical lens by less than 15°, as it is unclear how a wall can be “offset” by a number of degrees. Specifically, an “offset” implies some distance between the optical axis and the sidewall while 15° is a measure of an angle. It is unclear how any angle should be defined, if such an angle should be formed between the sidewall and the optical axis, or if there is some additional method of determining the “offset.” For the purposes of examination, any side surface of the protruding portion that is angled less than 15° relative to the optical axis will be interpreted as reading on the claimed invention.
Claims 2-8, 22-23, 26-32, and 34-36 are rejected as being dependent upon claim 1 and failing to cure the deficiencies of the rejected base claim.
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) 1-6, 22-23, and 26-32 is/are rejected under 35 U.S.C. 103 as being unpatentable over Chou (U.S. PG-Pub No. 2019/0235140) in view of Hsu et al. (U.S. PG-Pub No. 2018/0196171; hereinafter – “Hsu”).
Regarding claim 1, Chou teaches an optical lens, comprising:
a first lens element (111, 211, 311, 411, 511) having a first surface located on an object side and a second surface located on an image side, wherein a central region (112, 211a, 312, 412, 531) of the first surface protrudes toward the object side to form a protruding portion, a top surface of the protruding portion forms an optical area for imaging, the first surface further has a first structured area (111a, 111b, 211b, 311a, 311b, 411a, 511) surrounding the protruding portion, and a side surface of the protruding portion connects the optical area and the first structured area (See e.g. Figs. 1-5; Paragraphs 0071-0075, 0077-0083, 0086-0092, 0098, 0100, 0104, 0106, and 0108); and
a second lens component (110, 210, 310, 410, 510) comprising a second lens barrel (113, 213, 313, 413, 513) and at least one second lens element (121-125, 221-225, 321-325, 421-425, 521-525) mounted inside the second lens barrel, wherein the at least one second lens element and the first lens element together constitute an imageable optical system (See e.g. Figs. 1-5; Paragraphs 0071-0075, 0077-0083, 0086-0092, 0098, 0100, 0104, 0106, and 0108);
wherein the first lens element is not mounted in a lens barrel and is directly bonded to the second lens component by the second surface of the first lens element being directly bonded to a top surface of the second lens barrel (See e.g. Figs. 1-5; Paragraphs 0071-0075, 0077-0083, 0086-0092, 0098, 0100, 0104, 0106, and 0108).
Chou fails to explicitly disclose that the side wall of the protruding portion of the first lens element is offset from an optical axis of the optical lens by less than 15°.
However, Hsu teaches an optical lens assembly comprising a first lens element (1200) having a first surface located on an object side and a second surface located on an image side, wherein a central region (C2) of the first surface protrudes toward the object side to form a protruding portion, a top surface of the protruding portion forms an optical area for imaging, the first surface further has a first structured area (1211) surrounding the protruding portion, and a side surface (1212) of the protruding portion connects the optical area and the first structured area, and the side wall of the protruding portion of the first lens element is offset from an optical axis of the optical lens by less than 15° (See e.g. Figs. 1A-1B; Paragraphs 0035 and 0039-0040).
Hsu teaches this offset side wall as “it maintains the accurate alignment with the optical axis and reduces the failure of the assembling process” (Paragraph 0039).
Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the optical lens of Chou such that the side wall of the protruding portion of the first lens element is offset from an optical axis of the optical lens by less than 15° as in Hsu as “it maintains the accurate alignment with the optical axis and reduces the failure of the assembling process,” as taught by Hsu (Paragraph 0039), since it has been held that where the claimed ranges “overlap or lie inside ranges disclosed by the prior art” a prima facie case of obviousness exists, In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976) (See MPEP 2144.05.I.), and since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art, In re Aller, 105 USPQ 233 (C.C.P.A. 1955).

Claim(s) 1-6, 22-23, 26-32, and 34-36 is/are rejected under 35 U.S.C. 103 as being unpatentable over Wang et al. (Chinese Pub. No. 207336891 U; hereinafter – “Wang”) in view of Chou and Hsu. All citations to Wang are directed toward the English machine translation of Wang, provided as a reference.
Regarding claim 1, Wang teaches an optical lens, comprising:
a first lens element (11) having a first surface located on an object side and a second surface located on an image side, wherein a central region (1111, 1121) of the first surface protrudes toward the object side to form a protruding portion, a top surface of the protruding portion forms an optical area (1111, 1121) for imaging, the first surface further has a first structured area (1122) surrounding the protruding portion, and a side surface of the protruding portion connects the optical area and the first structured area (See e.g. Fig. 1-7; Paragraphs 0065-0066, 0075, 0078, 0092, 0095-0096, 0102, and 0117-0118); and

wherein the second surface of the first lens element is bonded to a top surface of the second lens barrel (See e.g. Figs. 1-7; Paragraphs 0076, 0083-0084, 0090, 0098, 0107, 0112, 0115, and 0119).
Wang fails to explicitly disclose that the first lens element is not mounted in a lens barrel and is directly bonded to the second lens component by the second surface of the first lens element being directly bonded to a top surface of the second lens barrel.
However, Chou teaches an imaging lens assembly with dual molded optical element comprising a first lens element (111, 211, 311, 411, 511) having a first surface located on an object side and a second surface located on an image side, wherein a central region (112, 211a, 312, 412) of the first surface protrudes toward the object side to form a protruding portion, a top surface of the protruding portion forms an optical area for imaging, the first surface further has a first structured area (111a, 111b, 211b, 311a, 311b, 411a) surrounding the protruding portion, and a side surface of the protruding portion connects the optical area and the first structured area, a second lens component comprising a second lens barrel and at least one second lens element mounted inside the second lens barrel, and the first lens element is not mounted in a lens barrel and is directly bonded to the second lens component by the second surface of the first lens element being directly bonded to a top surface of the second lens barrel (See e.g. Figs. 1-5; Paragraphs 0071-0075, 0077-0083, 0086-0092, 0098, 0100, 0104, 0106, and 0108).
Chou teaches this first lens element directly bonded to a top surface of the second lens barrel “so that the generation of stray light can be avoided” (Paragraph 0038), such that “it is not easy to cause reflections inside the imaging lens assembly when stray light enters therein so as to reduce the effects of the stray light” (Paragraph 0063) and “to increase the surface precision of the optical effective section” (Paragraph 0065).
Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the optical lens of Wang with the first lens element directly bonded to a top surface of the second lens barrel of Chou “so that the generation of stray light can be avoided,” such that “it is not easy to cause reflections inside the imaging lens assembly when stray light enters therein so as to reduce the effects of the stray light” and “to increase the surface precision of the optical effective section,” as in Chou (Paragraphs 0038, 0063, and 0065).
Wang and Chou fail to explicitly disclose that the side wall of the protruding portion of the first lens element is offset from an optical axis of the optical lens by less than 15°.
However, Hsu teaches an optical lens assembly comprising a first lens element (1200) having a first surface located on an object side and a second surface located on an image side, wherein a central region (C2) of the first surface protrudes toward the object side to form a protruding portion, a top surface of the protruding portion forms an optical area for imaging, the first surface further has a first structured area (1211) surrounding the protruding portion, and a side surface (1212) of the protruding portion connects the optical area and the first structured area, and the side wall of the protruding portion of the first lens element is offset from an optical axis of the optical lens by less than 15° (See e.g. Figs. 1A-1B; Paragraphs 0035 and 0039-0040).
Hsu teaches this offset side wall as “it maintains the accurate alignment with the optical axis and reduces the failure of the assembling process” (Paragraph 0039).
Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the optical lens of Wang such that the side wall of the protruding portion of the first lens element is offset from an optical axis of the optical lens by less than 15° as in Hsu as “it maintains the accurate alignment with the optical axis and reduces the failure of the assembling process,” as taught by Hsu (Paragraph 0039), since it has been held that where the claimed ranges “overlap or lie inside ranges disclosed by the prior art” a prima facie case of obviousness exists, In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976) (See MPEP 2144.05.I.), and since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art, In re Aller, 105 USPQ 233 (C.C.P.A. 1955).

Claim(s) 1-8, 22-23, and 26-32 is/are rejected under 35 U.S.C. 103 as being unpatentable over Genda (U.S. PG-Pub No. 2010/0254027) in view of Chou and Hsu.
Regarding claim 1, Genda teaches an optical lens, comprising:
a first lens element (101, 103, and/or 116) having a first surface located on an object side and a second surface located on an image side, wherein a central region (108) of the first surface protrudes toward the object side to form a protruding portion, a top surface of the protruding portion forms an optical area (108) for imaging, the first surface further has a first structured area (103 and/or 116) surrounding the protruding portion, and a side surface (106) of the protruding portion connects the optical area and the first structured area (See e.g. Figs. 2-3 and 5-6; Paragraphs 0039-0053); and

wherein the second surface of the first lens element is bonded to a top surface (205a or 120) of the second lens barrel (See e.g. Figs. 2-3 and 5-6; Paragraphs 0065-0085, 0088, 0096, 0107-0110, and 0123-0126).
Genda fails to explicitly disclose that the first lens element is not mounted in a lens barrel and is directly bonded to the second lens component by the second surface of the first lens element being directly bonded to a top surface of the second lens barrel.
However, Chou teaches an imaging lens assembly with dual molded optical element comprising a first lens element (111, 211, 311, 411, 511) having a first surface located on an object side and a second surface located on an image side, wherein a central region (112, 211a, 312, 412) of the first surface protrudes toward the object side to form a protruding portion, a top surface of the protruding portion forms an optical area for imaging, the first surface further has a first structured area (111a, 111b, 211b, 311a, 311b, 411a) surrounding the protruding portion, and a side surface of the protruding portion connects the optical area and the first structured area, a second lens component comprising a second lens barrel and at least one second lens element mounted inside the second lens barrel, and the first lens element is not mounted in a lens barrel and is directly bonded to the second lens component by the second surface of the first lens element being directly bonded to a top surface of the second lens barrel (See e.g. Figs. 1-5; Paragraphs 0071-0075, 0077-0083, 0086-0092, 0098, 0100, 0104, 0106, and 0108).
Chou teaches this first lens element directly bonded to a top surface of the second lens barrel “so that the generation of stray light can be avoided” (Paragraph 0038), such that “it is not easy to cause reflections inside the imaging lens assembly when stray light enters therein so as to reduce the effects of the stray light” (Paragraph 0063) and “to increase the surface precision of the optical effective section” (Paragraph 0065).
Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the optical lens of Genda with the first lens element directly bonded to a top surface of the second lens barrel of Chou “so that the generation of stray light can be avoided,” such that “it is not easy to cause reflections inside the imaging lens assembly when stray light enters therein so as to reduce the effects of the stray light” and “to increase the surface precision of the optical effective section,” as in Chou (Paragraphs 0038, 0063, and 0065).

Hsu teaches this offset side wall as “it maintains the accurate alignment with the optical axis and reduces the failure of the assembling process” (Paragraph 0039).
Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the optical lens of Genda such that the side wall of the protruding portion of the first lens element is offset from an optical axis of the optical lens by less than 15° as in Hsu as “it maintains the accurate alignment with the optical axis and reduces the failure of the assembling process,” as taught by Hsu (Paragraph 0039), since it has been held that where the claimed ranges “overlap or lie inside ranges disclosed by the prior art” a prima facie case of obviousness exists, In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976) (See MPEP 2144.05.I.), and since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art, In re Aller, 105 USPQ 233 (C.C.P.A. 1955).
