Office Action

§112
DETAILED ACTION 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 . Status of Claims Claims 1-2, 5-7, 9-10, 12-13 and 16 are amended. Claims 14-15 are cancelled. Claim 17 is new. Claim 3 is withdrawn. Claims 1-2, 4-13 and 16-17 are examined herein. 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 1-2, 4-13 and 16-17 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 “applying an external magnetic field to at least one raw form” in line 5, which includes an embodiment that the magnetic field is only applied to one raw form. Claim 1 also recites applying an external magnetic field to both the first raw form and the second raw form in line 9-14. It’s unclear whether the magnetic field is applied to at least one of the raw forms or both of the raw forms. Appropriate correction is required. Claim 12 recites “at least one compound selected from the group consisting of aluminum oxide, zirconium oxide, yttrium oxide, and at least one rare-earth-oxide. The “at least one” prior to “rare-earth oxide” should be deleted. Appropriate correction is required. Claim 17 recites “after manufacturing of the raw form” in line 3. It’s unclear whether “the raw form” refers to the first and the second raw form, or the third raw form. Appropriate correction is required. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(d): (d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. The following is a quotation of pre-AIA 35 U.S.C. 112, fourth paragraph: Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. Claims 4, 7-8 and 11 are rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. Claim 1 recites that the magnetic field is applied during the manufacturing of the first- and the second- raw form. Claim 4 depends from claim 1 and recites an embodiment that the magnetic field is applied after manufacturing of the first and the second raw form, which does not further limit claim 1. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. Claim 1 recites that the first and the second raw forms are made by injection molding. Claim 7 depends from claim 1 and recites an embodiment that the magnet is made by additive manufacturing, extrusion, cold pressing, dry pressing and wet pressing, which does not further limit claim 1. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. Claim 8 does not further limit claim 1 as claim 1 already recites the limitation “the second raw form is injection molded onto the first raw form by injection molding, wherein the third raw form is manufactured”. Claim 1 recites that the second raw form is injection molded onto the first raw form, indicating that the second raw form is in direct contact with the first raw form. Claim 11 depends from claim 1 and recites there is a separating layer between the first- and the second- raw form, which does not further limit claim 1. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
