Office Action

§103 §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 . Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Election/Restrictions Claims 1-4, 7-13, 16-17, 21, and 24-25 are allowable. The requirement for unity of invention among Species A-G, as set forth in the Office action mailed on 08/26/2025, has been reconsidered in view of the allowability of claims to the elected invention pursuant to MPEP § 821.04(a). The restriction requirement is hereby withdrawn as to any claim that requires all the limitations of an allowable claim. Claim 6, directed to a non-elected species, is no longer withdrawn from consideration because the claim(s) requires all the limitations of an allowable claim. However, claims 14-15, directed to non-elected species, remain withdrawn from consideration because they do not require all the limitations of any allowable claim. In view of the above noted withdrawal of the requirement for unity of invention, applicant is advised that if any claim presented in a divisional application is anticipated by, or includes all the limitations of, a claim that is allowable in the present application, such claim may be subject to provisional statutory and/or nonstatutory double patenting rejections over the claims of the instant application. Once a restriction requirement is withdrawn, the provisions of 35 U.S.C. 121 are no longer applicable. See In re Ziegler, 443 F.2d 1211, 1215, 170 USPQ 129, 131-32 (CCPA 1971). See also MPEP § 804.01. Drawings The drawings were received on 06/01/2026. These drawings are acceptable. Specification The substitute specification filed 06/01/2026 has been entered. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claim 6 is rejected under 35 U.S.C. 112(a) or pre-AIA 35 U.S.C. 112, first paragraph, as based on a disclosure which is not enabling. The disclosure does not enable one of ordinary skill in the art to practice the invention without a haptic actuator, which is/are critical or essential to the practice of the invention but not included in claim 6 nor its parent claim 1. See In re Mayhew, 527 F.2d 1229, 188 USPQ 356 (CCPA 1976). A user is simply incapable of applying the recited force to the input panel in a second direction anti-parallel to the first direction, wherein said first direction is perpendicular to the input surface. For this reason, the limitation “unit force applied to the input panel along a second, different, direction” in combination with the limitation “wherein the second direction is anti-parallel to the first direction” is not enabled for the embodiment (if any) which Applicant intends for claim 6 to cover. 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. Claim 6 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. Claim 6 recites “the second direction is anti-parallel to the first direction.” Parent claim 1 requires said first direction to be “a first direction perpendicular to the input surface”, such that the second direction of claim 6 must also be perpendicular to the input surface. Although a user may readily press the input panel to provide input in the first direction, said user is simply incapable of lifting the input panel to provide input in the second direction. For this reason, the limitation “unit force applied to the input panel along a second, different, direction” in combination with the limitation “wherein the second direction is anti-parallel to the first direction” is misdescriptive of the embodiment (if any) which Applicant intends for claim 6 to cover. Regarding claim 6: In the absence of a reasonably definite interpretation of a claim, it is improper to rely on speculative assumptions regarding the meaning of a claim and then base a rejection under 35 U.S.C. 103 on these assumptions (In re Steele, 305 F.2d 859,134 USPQ 292 (CCPA 1962)). See MPEP 2143.03. Allowable Subject Matter Claims 1-4, 7-13, 16-17, 21, and 24-25 are allowed. See reasons for indicating allowable subject matter stated in the non-final rejection mailed 02/11/2026. Response to Arguments Applicant's arguments filed 06/01/2026 have been fully considered but they are moot in view of the new grounds of rejection. Conclusion Applicant's amendment necessitated the rejoinder-in-part, which 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.
