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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 5, 12, and 21 are rejected under 35 U.S.C. 103 as being unpatentable over US1 as applied to Claims 4, 11, and 20 above. US1 describes an optical fiber connector as set forth above (see above regarding Claims 4, 11, 20). US1 further describes an outer housing portion (12) configured to receive the housing portion and the connector subassembly (see Fig 1 and [0027], [0030]). US1 does not describe the connector comprising a subscriber (SC) connector. SC connectors are well-known in the art to commonly utilize housing structures with an internal fiber assembly. Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art to use the subassembly of US1 in an SC connector structure. The motivation for doing so would have to been provide eccentricity compensation to reduce optical losses (see US1 at [0015]-[0017]) in a commonly known and used form factor. Allowable Subject Matter Claims 2, 7, and 15 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Claims 2 describes a front end of the biasing portion configured to abut a rearward facing surface of the holding portion. Claims 7 and 15 each describe a front end of the biasing portion configured to abut a rearward facing surface of the holding portion. These limitations represent subject matter not described or reasonably suggested, in conjunction with the further limitations of the present claims, by the prior art of record. Conclusion The prior art cited in the attached form PTO-892 are made of record and considered pertinent to applicant's disclosure. The cited prior art described optical connector subassemblies including tuning portions and/or biasing portions.
