CTNF 18/866,148 CTNF 88007 DETAILED ACTION Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Specification The abstract of the disclosure is objected to because of undue length. A corrected abstract of the disclosure is required and must be presented on a separate sheet, apart from any other text. See MPEP § 608.01(b). 06-16 AIA Applicant is reminded of the proper language and format for an abstract of the disclosure. The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words in length. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details. The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, “The disclosure concerns,” “The disclosure defined by this invention,” “The disclosure describes,” etc. In addition, the form and legal phraseology often used in patent claims, such as “means” and “said,” should be avoided. Claim Rejections - 35 USC § 112 07-30-02 AIA 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. 07-34-01 Claim 9 is 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. 07-34-13 AIA Claim 9 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA), second paragraph, as being incomplete for omitting essential elements, such omission amounting to a gap between the elements. See MPEP § 2172.01. The omitted elements are: It is unclear “the amount” in which Applicant is referring when reciting a first compression amount and a second compression amount .

Re: Claim 7. (Currently Amended) The wearable device according to claim 1, wherein the latch and the middle frame are connected by using an elastic element (147), and the elastic element is used to provide the latch with a recovery force for returning from the second position to the first position. Re: Claim 8. (Currently Amended) The wearable device according to claim 7, wherein along the first direction, the elastic element is located on a side that is of the latch and that faces away from the button (see Figs. 8-9 and 14-15). Re: Claim 9. (Currently Amended) The wearable device according to claim 7, wherein when the latch is in the first position, the elastic element has a first compression amount, or when the latch is in the second position, the elastic element has a second compression amount, and wherein the second compression amount is greater than the first compression amount (see Figs. 8-9 and 14-15).
