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.
Claim(s) 1-2 and 4-10 s/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Neikirk et al. (US 20190376182).
Regarding Claim 1:
Neikirk teaches a system for treating fine powder particles comprising: a rotary treatment vessel (reactor system 100) configured to expose a plurality of particles to treatment gases or vapors; a controller (controller 170) configured to rotate the rotary treatment vessel at a first rotation speed (a rotational speed of the rotary vacuum chamber 112 is less than a threshold rotational speed, e.g., less than 15 rpm, such that particles 148 within the rotary vacuum chamber experience tumbling agitation while the rotary vacuum chamber 112 is in rotational motion) to establish a cataracting condition [Fig. 1 & 0092], and at a second rotation speed to establish a centrifuging condition (controller 170 can control the drum motor 130a to rotate the vacuum chamber 112 at speeds up to 200 rpm, such that particles 148 are centrifugally moved) [Fig. 1 & 0079]; and a comb (paddle assembly 132) movable from a first position while the rotary treatment vessel is rotated at the first rotation speed, to a second position while the rotary treatment vessel is rotated at the second rotation speed (the paddle assembly can be rotated after either the first rotation speed or second rotation speed is applied in steps 805 or 804, respectively. As such, the paddle assembly is being moved between different positions at either rotation speed) [Fig. 8 & 0061, 0117-0119].
Furthermore, although taught by the cited prior art, the limitations “movable from a first position while the rotary treatment vessel is rotated at the first rotation speed, to a second position while the rotary treatment vessel is rotated at the second rotation speed,” are merely intended use and are given weight to the extent that the prior art is capable of performing the intended use. A claim containing a “recitation with respect to the manner in which a claimed apparatus is intended to be employed does not differentiate the claimed apparatus from a prior art apparatus” if the prior art apparatus teaches all the structural limitations of the claim. Ex parte Masham, 2 USPQ2d 1647 (Bd. Pat. App. & Inter. 1987).
Regarding Claim 2:
Neikirk teaches wherein the comb rotates from the first position to the second position (the paddle assembly can be rotated using motor 130b, and as such, moves from a second position to a first position) [Fig. 2 , 8 & 0058].
Furthermore, although taught by the cited prior art, the limitations of claim 2 are merely intended use and are given weight to the extent that the prior art is capable of performing the intended use. A claim containing a “recitation with respect to the manner in which a claimed apparatus is intended to be employed does not differentiate the claimed apparatus from a prior art apparatus” if the prior art apparatus teaches all the structural limitations of the claim. Ex parte Masham, 2 USPQ2d 1647 (Bd. Pat. App. & Inter. 1987).
Regarding Claim 4:
Neikirk teaches wherein the first rotation speed is less than 100 RPM (a rotational speed of the rotary vacuum chamber 112 is less than a threshold rotational speed, e.g., less than 15 rpm, such that particles 148 within the rotary vacuum chamber experience tumbling agitation while the rotary vacuum chamber 112 is in rotational motion) to establish a cataracting condition [Fig. 1 & 0092].
Regarding Claim 5:
Neikirk teaches wherein the second rotation speed is greater than 15 RPM (centrifugal force can be achieved by speeds greater than 15 rpm) [Fig. 1 & 0079].
Regarding Claim 6:
Neikirk teaches one or more gas injectors (gas inlet port 120) configured to intermittently introduce treatment gases or vapors into the rotary treatment vessel while the rotary treatment vessel rotates at the first rotation speed (a process gas is injected in step 810 either during the first rotation speed 805 or a second rotation speed 804) [Fig. 2, 8 & 0057, 0117-0118, 0121].
Regarding Claim 7:
Neikirk teaches wherein the one or more gas injectors are configured to uniformly raise a pressure inside the rotary treatment vessel (reactants can be fed via gas inlet port 120 to achieve specified pressures within the reactor system 100) [Fig. 2 & 0126].
Furthermore, although taught by the cited prior art, the limitations of claim 7 are merely intended use and are given weight to the extent that the prior art is capable of performing the intended use. A claim containing a “recitation with respect to the manner in which a claimed apparatus is intended to be employed does not differentiate the claimed apparatus from a prior art apparatus” if the prior art apparatus teaches all the structural limitations of the claim. Ex parte Masham, 2 USPQ2d 1647 (Bd. Pat. App. & Inter. 1987).
Regarding Claim 8:
Neikirk teaches a vacuum port (vacuum port 118) with an isolation valve (isolation valve 139b) to intermittently exhaust treatment gases or vapors from the rotary treatment vessel while the rotary treatment vessel rotates at the second rotation speed (the rotary treatment vessel exhausts gases in step 806 after either the first rotation speed or second rotation speed is applied in steps 805 or 804, respectively) [Fig. 8 & 0057, 0117-0119].
Furthermore, although taught by the cited prior art, the limitations “to intermittently exhaust treatment gases or vapors from the rotary treatment vessel while the rotary treatment vessel rotates at the second rotation speed,” are merely intended use and are given weight to the extent that the prior art is capable of performing the intended use. A claim containing a “recitation with respect to the manner in which a claimed apparatus is intended to be employed does not differentiate the claimed apparatus from a prior art apparatus” if the prior art apparatus teaches all the structural limitations of the claim. Ex parte Masham, 2 USPQ2d 1647 (Bd. Pat. App. & Inter. 1987).
Regarding Claim 9:
Neikirk teaches wherein the comb includes rake-shaped tines (tines 606) [Fig. 6A & 0099], configured to break up agglomerates formed by the plurality of particles, movement of the comb to the first position placing the tines into contact with at least a portion of the plurality of particles (in some implementations, the at least one paddle includes a rake-shaped feature including multiple tines such that the tines of the paddles are in contact with the particles when the chemical delivery system is injecting the process gas into the particles) [Fig. 2 & 0016, 0094].
Furthermore, the limitations “configured to break up agglomerates formed by the plurality of particles, movement of the comb to the first position placing the tines into contact with at least a portion of the plurality of particles, and movement of the comb to the second position placing the tines out of contact with the plurality of particles,” are merely intended use and are given weight to the extent that the prior art is capable of performing the intended use. A claim containing a “recitation with respect to the manner in which a claimed apparatus is intended to be employed does not differentiate the claimed apparatus from a prior art apparatus” if the prior art apparatus teaches all the structural limitations of the claim. Ex parte Masham, 2 USPQ2d 1647 (Bd. Pat. App. & Inter. 1987). It is noted that the controller 170 can operate drum motor 130a to rotate the paddle assembly 132, therefore the paddle 132 would be capable of being moved in positions contacting the plurality of particles, or not contacting the plurality of particles [Fig. 2 & 0016, 0094],
Regarding Claim 10:
Neikirk teaches wherein the rotary treatment vessel is mounted horizontally (as evidenced by Fig. 2, the reactor system 100 is mounted horizontally) [Fig. 2 & 0057].
Claim Rejections - 35 USC § 103
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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claim(s) 3 is/are rejected under 35 U.S.C. 103 as being unpatentable over Neikirk et al. (US 20190376182), as applied to claims 1-2 and 4-10 above, and further in view of Wang et al. (US 6383954).
The limitations of claims 1-2 and 4-10 have been set forth above.
Regarding Claim 3:
Neikirk does not specifically disclose the comb translates longitudinally in a direction parallel to a longitudinal axis of the rotary treatment vessel from the first position to the second position.
Although Wang does not specifically disclose "wherein the comb translates longitudinally in a direction parallel to a longitudinal axis of the rotary treatment vessel from the first position to the second position," Wang does disclose that allowing a nozzle to retract allows for better control over gas flows [Wang - Col. 9 lines 40-44]. As such, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the combs of Wang to be longitudinally retractable to improve control over fluid flow [Wang - Col. 9 lines 40-44]. It is noted that the comb (paddle assembly 132) feed gas, and as such, can be considered gas nozzles [Neikirk - Fig. 2 & 0061].
Claim(s) 11-12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Neikirk et al. (US 20190376182), as applied to claims 1-2 and 4-10 above, and further in view of Park et al. (US 20150144060), with Lei et al. (US 9355907) as an evidentiary reference.
The limitations of claims 1-2 and 4-10 have been set forth above.
Regarding Claim 11:
Neikirk does not specifically disclose a plurality of radially arrayed rotary treatment vessels, wherein the controller rotates the plurality of rotary treatment vessels at the second rotation speed around a common axis of rotation.
Park does not specifically disclose "a plurality of radially arrayed rotary treatment vessels," however Park does disclose that a system comprising a plurality of treatment apparatuses as opposed to a single one would help improve throughput [Park - 0049]. As such, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the system of Neikirk to comprise of a plurality of treatment vessels to help improve throughput [Park - 0049]. Lei et al. (US 9355907) also discloses that using multiple treatment vessels improves throughput [Lei -Col. 13 lines 1-7].
Furthermore, although Neikirk modified by Park does not specifically disclose "wherein the controller rotates the plurality of rotary treatment vessels at the second rotation speed around a common axis of rotation," Neikirk does disclose an individual rotary vessel rotating at the second rotation speed (controller 170 can control he drum motor 130a to rotate the vacuum chamber 112 at speeds up to 200 rpm, such that particles 148 are centrifugally moved) [Neikirk - Fig. 1 & 0092]; As such, modifying a plurality of chambers to rotate at the second rotation speed would merely be applying a known technique to achieve predictable results (See MPEP 2143 D).
Regarding Claim 12:
Neikirk does not specifically disclose wherein each rotary treatment vessel of the plurality of rotary treatment vessels defines a longitudinal axis, and the controller rotates each rotary treatment vessel of the plurality of rotary treatment vessels at the first rotation speed around its respective longitudinal axis.
Park does not specifically disclose "a plurality of radially arrayed rotary treatment vessels," however Park does disclose that a system comprising a plurality of treatment apparatuses as opposed to a single one would help improve throughput [Park - 0049]. As such, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the system of Neikirk to comprise of a plurality of treatment vessels to help improve throughput [Park - 0049]. Lei et al. (US 9355907) also discloses that using multiple treatment vessels improves throughput [Lei -Col. 13 lines 1-7]. Furthermore, since the plurality of vessels would be three-dimensional objects, longitudinal axes would be defined.
Furthermore, although Neikirk modified by Park does not specifically disclose "the controller rotates each rotary treatment vessel of the plurality of rotary treatment vessels at the first rotation speed around its respective longitudinal axis," Neikirk does disclose an individual rotary vessel rotating at the second rotation speed (a rotational speed of the rotary vacuum chamber 112 is less than a threshold rotational speed, e.g., less than 15 rpm, such that particles 148 within the rotary vacuum chamber experience tumbling agitation while the rotary vacuum chamber 112 is in rotational motion) to establish a cataracting condition [Neikirk - Fig. 1 & 0079], As such, modifying a plurality of chambers to rotate at the first rotation speed would merely be applying a known technique to achieve predictable results (See MPEP 2143 D).
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant’s
disclosure. Frankel et al. (US 20200340108) and Hoener et al. (US 20180353923) teach rotary treatment vessels [Frankel – Fig. 1; Hoener – Fig. 1A].
