Office Action

§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 . Status This Office Action is in response to the remarks and amendments filed on 1/12/2026. The 35 USC 112 rejections have been withdrawn. Claims 1,4-8,10-18 and 20 remain pending for consideration on the merits. Election/Restrictions Applicant’s election without traverse of Species A, fig. 1 and Species AA, Fig. 2 in the reply filed on is acknowledged. Claims 10-14, 17-18 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected species, there being no allowable generic or linking claim. Claims 10-14, 17-18 are directed to nonelected species B, Fig. 6. Election was made without traverse in the reply filed on 9/30/2025. Newly submitted claim 1 directed to an invention that is independent or distinct from the invention originally claimed for the following reasons: Claim 2, as originally filed recited in alternative, “the at least one fog collection device comprises: a mesh body positionable adjacent the vaporizer”, which is directed to unelected subspecies CC, Fig. 4, as outlined in the Restriction Requirement dated 8/13/2025. Claim 1, as amended now recites “a mesh body positionable around a fence that surrounds the vaporizer or near a fence line for such fencing or positionable within the housing or between the housing and the vaporizer”. The specification describes in paragraph 0063, in some embodiments…for example, the mesh body 40 can be positioned around a fence that surrounds the vaporizer 7 or can be positioned near a fence line for such fencing. Such positioning of a mesh body 40 can be a positioning that is adjacent to the vaporizer 7. Adjacent positioning can also include positioning that permits the mesh body to collect and remove fog that forms near the vaporizer 7 (e.g. within a fence line of fencing that can surround the vaporizer or the vaporizer and other equipment, etc.). The amendment including the mesh body and fence are directed to an invention that is independent or distinct from the invention originally claimed. Since applicant has received an action on the merits for the originally presented invention, this invention has been constructively elected by original presentation for prosecution on the merits. Accordingly, claims 1,4-8,15-16 and 20 withdrawn from consideration as being directed to a non-elected invention. See 37 CFR 1.142(b) and MPEP § 821.03. To preserve a right to petition, the reply to this action must distinctly and specifically point out supposed errors in the restriction requirement. Otherwise, the election shall be treated as a final election without traverse. Traversal must be timely. Failure to timely traverse the requirement will result in the loss of right to petition under 37 CFR 1.144. If claims are subsequently added, applicant must indicate which of the subsequently added claims are readable upon the elected invention. Should applicant traverse on the ground that the inventions are not patentably distinct, applicant should submit evidence or identify such evidence now of record showing the inventions to be obvious variants or clearly admit on the record that this is the case. In either instance, if the examiner finds one of the inventions unpatentable over the prior art, the evidence or admission may be used in a rejection under 35 U.S.C. 103 or pre-AIA 35 U.S.C. 103(a) of the other invention. Drawings The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, “a mesh body positionable around a fence that surrounds the vaporizer or near a fence line for such fencing or positionable within the housing or between the housing and the vaporizer; and at least one fan positionable below the vaporizer, a body of the at least one fan moveable to mitigate the fog” must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. 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. 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.
