Office Action

§102 §103
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 . The previous office action has been withdrawn. Drawings The drawings are objected to because: Claims 49, 50, vaporize contact pins that require elimination of any spring driven feature or that have solid structure that does not require relative movement of conductive pin parts. If prevent those items should be pointed out by figure number and numeral. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as "amended." If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either "Replacement Sheet" or "New Sheet" pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Rejections - 35 USC § 102 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 45, 47, 48 are rejected under 35 U.S.C. 102(a,1) as being anticipated by Nettenstrom (U. S. Patent 11,123,501). Regarding claims 45, 47, 48, Nettenstrom, see figures 1, 4, discloses a vaporizer device comprising an electrical contact pin (spring) at 35 for electrical coupling with a contact 212A, 212B of a cartridge 200 (see figure 1) configured to be insertably received within a cartridge-receiving receptacle of a vaporizer device body 300, the electrical contact pin (spring) at 35 comprising a liquid-resistant feature. Since such feature as broadly stated in specification (paragraph 0089) may include a "structure feature (modified construction)" does not define over the reference contact spring as disclosed. The limitation is readable on any selected structural features (thickness, length, material) of the spring. Claims 47, 48, references spring is readable as including "a structural feature" meet by spring on pin 35 as discussed above. 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. Claims 44-48 are rejected under 35 U.S.C. 103 as being unpatentable over Nettenstrom in view of Kim (U. S. Patent 9780475). For claims 44, 45, Nettenstrom, see figure 4, electrical spring contact pin (pogo pins) 35 are for coupling to contacts 212A, 212B of a cartridge 200 (figure 1) configured to be insertably received within a receptacle of a vaporizer body 300. The contact pin does not specifically disclose the contact pin to include "a liquid resistant feature". Kim, column 2, lines 50-60 disclose spring pin use in which the pin may be: 1) formed of nonconductive material or 2) formed of metal coated with a dielectric. It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to modify Nettenstrom to form pins 35 in either such manners (1 or 2), either of these changes are to avoid damage to the spring and are each one readable as forming a liquid-resistant feature". Regarding claim 46, Nettenstrom discloses the liquid-resistant feature comprises a spring for urging a plunger of the electrical contact pin 35, the spring being formed of and/or coated with a material that has a reduced conductivity relative to the plunger and/or to a barrel within which the plunger moves. Use of the spring pin formed as discussed for claim 45 rejections would meet claim 46 with such pin would have lower reduced conductively relative to plunger and/or barrel relative to the spring. Claims 47 and 48 also meet by the spring so formed, the changes each readable as a structural feature. Claims 49 and 50 are rejected under 35 U.S.C. 103 as being unpatentable over Nettenstrom in view of Paul (U. S. Patent 7,070,434). For claims 49 and 50, Nettenstrom pin contacts 35 lacks teaching of pin that require elimination of spring driven feature and (for claim 50) lacks use of rigid contact that does not require movement of conductive parts relative to each other. Paul discloses at figure 7, use mating contacts 434, 756 with contact 756 being rigid and requires no spring feature or relative movement of conductive parts. It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to modify Nettenstrom to provide such features as taught by Paul because this would enable omission of complex pogo pin contacts on the vaporizer body receptacle. Allowable Subject Matter Claims 31-43 are allowed. The following is an examiner's statement of reasons for allowance: None of the references discloses a vaporizer device comprising; a vaporizer device body shell; an internal skeleton disposed within the vaporizer device body shell; and a gasket configured to prevent passage of liquids between a volume within a cartridge e-receiving receptacle of a vaporizer device body and a volume within the vaporizer device body shell containing internal electronic circuitry, wherein the gasket comprises a connective feature via which a pressure sensing device that is connected to part of the internal electronic circuitry is exposed to air pressure in the cartridge- receiving receptacle, and the gasket comprises a supportive rib positioned to be compressed between the vaporizer device body shell and a part of the internal skeleton. 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."
