DETAILED ACTION
This Office action is in response to the amendment and remarks filed on November 25th, 2025. Claims 1-14 and 16-18 are pending.
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 .
Claim Interpretation
The original disclosure posits two forms of detector. One form is a unitary detector with an engineered discontinuity to act as an input aperture. The claims do not recite this embodiment. The second for is a detector “comprising: (i) first and second detector elements associated so as to form an interface … wherein the associated first and second detector elements … define on one side an environment internal the detector and on the other side an environment external the detector”. The independent claim clearly references this form of detector, as shown by the fact that it claims “first and second housing elements defining a space therebetween; … the first and second housing elements … defining on one side an environment internal the particle detector and on another side an environment external the particle detector”. In this form of detector, the interface forms a natural opening which can, and generally will, function as the input aperture.
Examiner can find no mention in the original disclosure of a detector including both an interface and a discontinuity. Therefore, the “input aperture to admit a particle beam” is not present in configuration with first and second housing elements, unless the interface is itself considered to be the input aperture. It does not appear this is the case, and examiner will proceed with 112(a) and 102(a)(1) rejections on the assumption that the “input aperture to admit the particle beam” is a discontinuity in one or both of the housing elements. However, to cover all bases, examiner will also reject on 101 grounds under an alternative interpretation of the “input aperture to admit the particle beam” as meaning the interface is the input aperture.
Drawings
Replacement drawings were received on November 25th, 2025. These drawings are acceptable in that they do not include new matter and clarify the relationships between the electron emissive surfaces and will be entered. However, they still fail to show the electron emissive surfaces being surrounded as claimed. They also fail to show the newly claimed input aperture, unless that input aperture is the space itself.
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, the one or more emissive surfaces surrounded by the first and second housing elements must be shown or the feature(s) canceled from the claim(s). The replacement drawings show the electron emissive surfaces adjacent to first and second housing elements, but not surrounded by them. 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.
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, the input aperture must be shown or the feature(s) canceled from the claim(s). If applicant intends the input aperture to be the interface itself, they do not need to submit new drawings, but will need to state on the record that the input aperture is the space between the first and second housing elements. No new matter should be entered.

Claim Rejections - 35 USC § 112(a)
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.
Claims 1-14 and 16-18 rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention.
The claims now recite a particle detection system comprising both “an input aperture to admit a particle beam;” and “first and second housing elements defining a space therebetween”. The input aperture is understood here to refer to a discontinuity or opening in one of the detector elements. There is no evidence that applicant considered the use of such a discontinuity in a non-unitary detector. The use of such discontinuities is disclosed as an alternative to interfacing detector elements, and always as part of a unitary detector housing (see “In one embodiment of the first aspect, the detector comprises one or more electron emissive surfaces, the detector comprising: (i) first and second detector elements associated so as to form an interface, or (ii) a unitary detector element having a discontinuity,”).
Claim Rejections - 35 USC § 101
The following rejection is an alternative to the 112(a) rejection, covering the interpretation where the “input aperture to admit a particle beam” is considered to be the interface, that is, as the “space” between the first and second housing elements that the deformable member occupies.
35 U.S.C. 101 reads as follows:
Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
Claims 1-14 and 16-18 are rejected under 35 U.S.C. 101 because
the disclosed invention is inoperative and therefore lacks utility.
Claim 1, from which all the other claims depend, recites a particle detection system comprising detection surfaces for detecting particles (electron emissive surfaces) surrounded by housing elements and a deformable member between them “wherein the deformable member or the deformable mass comprises a central region which when contacted by the first and/or second housing elements is deformed so as to inhibit or prevent passage of a gas through the space”. Such a configuration completely seals the internal environment and occludes the “input aperture” that is the interface, which prevents the particles the detector is meant to detect from reaching the detection surfaces. The application includes other embodiments that use tortuous paths or discontinuities to allow for the ions to reach the inner space while inhibiting a gas flow, but no such opening is disclosed for the deformable member.
While the claim language appears to allow for the space to be only partially filled by the deformable member/mass (“a deformable member or a deformable mass some or all of which occupies the space,”), the deformation by contact with the housing elements requires that the entire space be filled since there needs to a surface on the opposing side to push against. Claims 2 and 11 also specifically claim that the deformable member seals the opening, and that the deformable mass is compressed between the two elements, respectively.
Claim Rejections - 35 USC § 102
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 1-10 and 16-18 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by US 2009/0294654 (Steiner).
