Office Action

§DP
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 . Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the claims at issue are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); and In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on a nonstatutory double patenting ground provided the reference application or patent either is shown to be commonly owned with this application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The USPTO internet Web site contains terminal disclaimer forms which may be used. Please visit http://www.uspto.gov/forms/. The filing date of the application will determine what form should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to http://www.uspto.gov/patents/process/file/efs/guidance/eTD-info-I.jsp. Claims 1 and 13 are rejected on the ground of nonstatutory obviousness-type double patenting as being unpatentable over claim 5 of Patent 11902731. Although the conflicting claims are not identical, they are not patentably distinct from each other because: claim 5 of Patent 11902731 teaches all the limitations in the claims 1 and 13 of instant application because the claims of the instant application are obvious variations of the patented claims. Although the claimed ranges are not identical, the claimed ranges are still within the ranges as taught by the patented claims. Patent 11902731 Instant Application 18815835 1.

Cited prior art Jentz (US 2016/0134957) in view of Liu (US 11736850) teaches An open earphone, comprising: a sound production component (Jentz figure 5A); and an ear hook including a first portion and a second portion connected in sequence, wherein the first portion is hung between an auricle of a user and the head of the user, the second portion extends toward a front outer side of the auricle and connects to the sound production component (Liu figure 4B), and the sound production component is located close to an ear canal but does not block the opening of the ear canal (Jentz figure 2C), wherein: the open earphone and the auricle have a first projection and an eighth projection on a sagittal plane (Jentz figure 2B), however Jentz in combination with Liu does not teach “a centroid of a portion of the first projection corresponding to the sound production component have a first distance to a highest point of the eighth projection in a vertical axis direction, a ratio of the first distance to a height of the eighth projection in the vertical axis direction is within a range of 0.35-0.6; and in a non-wearing state, a distance from a centroid of a projection of the sound production component on a first plane to a projection of the first portion of the ear hook in the first plane is within a range of 13 mm-38 mm” and “a centroid of a portion of the first projection corresponding to the sound production component have a first distance from a highest point of the eighth projection in a vertical axis direction, a ratio of the first distance to a height of the eighth projection in the vertical axis direction is within a range of 0.25-0.4; and in a non-wearing state, a distance from a centroid of a projection of the sound production component on a first plane to a centroid of a projection of a first portion of the ear hook in the first plane is within a range of 10 mm-50 mm.” The following is an examiner’s statement of reasons for allowance: Independent claims 1 is allowed because the closest cited prior art either alone or in combination, fails to anticipate or render obvious, the claimed limitation of “a centroid of a portion of the first projection corresponding to the sound production component have a first distance to a highest point of the eighth projection in a vertical axis direction, a ratio of the first distance to a height of the eighth projection in the vertical axis direction is within a range of 0.35-0.6; and in a non-wearing state, a distance from a centroid of a projection of the sound production component on a first plane to a projection of the first portion of the ear hook in the first plane is within a range of 13 mm-38 mm” in combination with all other limitations in the claim(s) as defined by the applicant. Independent claims 13 is allowed because the closest cited prior art either alone or in combination, fails to anticipate or render obvious, the claimed limitation of “a centroid of a portion of the first projection corresponding to the sound production component have a first distance from a highest point of the eighth projection in a vertical axis direction, a ratio of the first distance to a height of the eighth projection in the vertical axis direction is within a range of 0.25-0.4; and in a non-wearing state, a distance from a centroid of a projection of the sound production component on a first plane to a centroid of a projection of a first portion of the ear hook in the first plane is within a range of 10 mm-50 mm” in combination with all other limitations in the claim(s) as defined by the applicant. Consequently, the disclosed independent claims are allowed on behalf of above-discussed reasons. Since the disclosed dependent claims 2-12, 14-20 are dependent on one of the independent claims, therefore they are also patentable Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to NORMAN YU whose telephone number is (571)270-7436.
