application filed on June 16, 2025.
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
Acknowledgment is made of applicant's claim for foreign priority based on an application filed in United Kingdom on June 17, 2024. It is noted, however, that applicant has not filed a certified copy of the UK application as required by 37 CFR 1.55.
Claim Rejections - 35 USC § 112
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 7 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 7, the limitation “a maximum allowable twist of at least one of the input shaft, output shaft, first layshaft, or second layshaft is one degree” is not fully understood. Is applicant attempting to define the twist (or the amount of elastic deformation in a rotational direction) of a shaft being one degree before the shaft fails, or intends to define the twist of a shaft being one degree at a given torque input? The limitation “maximum allow twist” fails to particularly point out the metes and bounds of the desired patent protection.
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) 1-5, 8-13, and 15 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Woods (USPub 2019/0170237).
Woods teaches a gearbox for (capable of being used with) a generator, the gearbox comprising: an input shaft (304) coupled to an input gear (302); an output shaft (332) coupled to an output gear (330); a first layshaft (310a) coupled to a first pair of splitter gears (308a,316a), wherein one of the first pair of splitter gears is configured to mesh with the input gear and the other of the first pair of splitter gears is configured to mesh with the output gear; and a second layshaft (310b) coupled to a second pair of splitter gears (308b,316b), wherein one of the second pair of splitter gears is configured to mesh with the input gear and the other of the second pair of splitter gears is configured to mesh with the output gear.
Claim 2: Woods teaches the input shaft and the output shaft are arranged along a first axis (352), the input shaft being axially spaced from the output shaft.
Claim 3: Woods teaches each of the first layshaft and the second layshaft are arranged parallel to the first axis.
Claim 4: Woods teaches the first layshaft is arranged along a second axis (350a) and the second layshaft is arranged along a third axis (350b), each of the second axis and the third axis being parallel to the first axis.
Claim 5: Woods teaches each of the first axis, second axis, and third axis are arranged within a same plane.
Claim 8: Woods illustrates a length of each of the first layshaft and the second layshaft is less than a combined length of the input shaft and the output shaft.
Claim 9: As described above, Woods teaches a gearbox capable of being used with a generator and an engine.
Claim 10: Woods teaches the input shaft is in line with the output shaft.
Claim 11: Woods teaches the first layshaft is disposed on a first side of each of the input shaft and the output shaft, and wherein the second layshaft is disposed on a second side of each of the input shaft and the output shaft, the first side being opposite the second side.
Claim 12: Woods teaches a power received by each of the first layshaft and the second layshaft is between one third and two thirds of the input power.
Claim 13: Woods teaches each of the input shaft, output shaft, first layshaft, and second layshaft are arranged in a same plane.
Claim 15: As described above, Woods teaches a gearbox, including first and second splitter gears (308), and first and second combination gears 316).
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.
Claim(s) 6, 14, 16, 17, and 26 is/are rejected under 35 U.S.C. 103 as being unpatentable over Woods (USPub 2019/0170237).
Woods does not disclose the specific ratio between the input and output gear. It would have been obvious to one having ordinary skill in the art before the effective filing of the claimed device to configure the size the gears of Woods to produce a desired speed reduction, such as 1.2:1 or 1.5:1; since it has been held that discovering an optimum value of a result effective variable involves only routine skill in the art. For example, It would have been obvious to one having ordinary skill in the art before the effective filing of the claimed device to configure the gearbox of Woods to produce a speed reduction of 1.2:1 or 1.5:1; motivation being to drive an output device at a predetermined speed to produce a desired outcome.
Woods does not teach the input gear and the output gear are respectively coupled to the input shaft and the output shaft via a spline connection. However, connecting a gear to a shaft with a spline connection was notoriously known in the art. It would have been obvious to one having ordinary skill in the art before the effective filing of the claimed device to connect the input and output gears to respective shafts of Woods, with a spline connection, as was notoriously known in the art, motivation being to provide a rotational coupling capable of transmitting a predetermined torque between components.
Claim(s) 7 is/are rejected under 35 U.S.C. 103 as being unpatentable over Woods (USPub 2019/0170237), as applied to claim 1 above, in further view of Mosher (USP 533,394).
Woods does not teach a maximum allowable twist of at least one of the input shaft, output shaft, first layshaft, or second layshaft is one degree. However, it was known in the art to configure a transmission so as to prevent twisting of a transmission shaft. For example, Mosher teaches a clutch device (B’) disposed between a shaft A’ and a gear (B) for preventing twisting of the transmission components. Mosher discloses “should the driven part be suddenly and unexpectedly stopped, the plate will yield and permit the driving shaft to continue its rotation without breaking or twisting any of the parts, as would be the case were the connection between the driving and driven members A and B a rigid one.” Lines 34-44. It would have been obvious to one of ordinary skill in the art before the effective filing of the claimed device to provide the transmission of Woods with a clutch device between the shaft(s) and gear(s), as taught by Mosher, motivation being to prevent twisting of the shafts if the transmission is overloaded.
Claim(s) 18 and 19 is/are rejected under 35 U.S.C. 103 as being unpatentable over Woods (USPub 2019/0170237), as applied to claim 15 above, in further view of Wolff et al. (USPub 2010/0294585).
Woods does not disclose the gearbox used to connect an engine to a generator. However, it was known to use a gearbox as defined by the claims. For example, Wolff teaches a combustion engine (32) connected to an input shaft of a gearbox (36), an output shaft of the gearbox connected to a generator (34). It would have been obvious to one of ordinary skill in the art at the time of effective filing of the claimed device to use the gearbox of Woods for connecting an engine to a generator, as taught by Wolff, motivation being to provide an electric power generating device that operates at a predetermined speed.
Wolff does not require a specific engine, but discloses a combustion reciprocating engine (32) for driving the generator. It was notorious well known in the art to configure an engine to operate with a gaseous fuel, such as propane, for providing an engine having reduced emissions. It would have been obvious to one of ordinary skill in the art to configure the generator arrangement of Woods modified with Wolff, as described above, with a known reciprocating engine that uses propane, motivation being to drive the generator with an engine having reduced emissions.
