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 .
Continued Examination Under 37 CFR 1.114
A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 11/10/2025 has been entered.
Examiner’s Note
Newly added claim 22 depends from withdrawn claim 17, and is hereby treated as withdrawn.
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.
Claim(s) 14 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by Costello (US 20060137837).
Regarding claim 14, Costello teaches (figs. 5-8) a connection assembly (figs. 5-8) configured to connect a pair of roller shade springs in series comprising:
a connector (102) defining a plurality of projections (132 and 134, see fig. 8) and a recess (opening on left wall), the plurality of projections and the recess are oriented on opposing sides of the connector (as shown in fig. 8),
wherein the plurality of projections are configured to directly engage a spring (50) of a first spring assembly (100), and the recess is configured to receive and interlock with a housing (110) of a second spring assembly (106) to connect the first spring assembly and the second sporting assemble in series (see fig. 6a), and
wherein in response to rotation of the connector, the spring of the first spring assembly and the housing of the second spring assembly rotate (paragraph 25 describes how force originating at B works its way to the roller tube causing the required rotation).
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.
Claim(s) 1-11, 13, and 21 are rejected under 35 U.S.C. 103 as being unpatentable over Costello (US 20060137837) in view of Huang (US 20180080278).
Regarding claim 1, Costello teaches (figs. 5-8) a roller shade comprising:
a roller tube (C);
a first spring assembly (104 is the first spring assembly) received by the roller tube, the first spring assembly including a first housing (each spring unit has a housing 110 per paragraph 25), a first shaft (each spring unit has a shaft 130 inside the housing extending from an adjacent unit) received by the first housing, a first spring member (each spring unit has a torsion spring 50) connected at one end to the first housing, and at an opposite end to the first shaft (as shown in fig. 7), wherein the first shaft is configured to rotate relative to the first housing (paragraph 25);
a second spring assembly (100) received by the roller tube, the second spring assembly including a second housing, a second shaft received by the second housing, a second spring member connected at one end to the second housing, and at an opposite end to the second shaft, wherein the second shaft is configured to rotate relative to the second housing (in the same way as the first spring assembly per paragraph 25); and
a connection assembly (102) including a third housing (110), a connector (132 and 134) received by the third housing (inside the housing), the connector defines a shaft (130) and a locking member (134), the connector is configured to rotate relative to the third housing.
Costello does not explicitly teach that the first shaft of the first spring assembly is configured to directly couple to the shaft defined by the connector, and the second housing of the second spring assembly is configured to directly couple to the locking member defined by the connector to connect the first spring assembly and the second spring assembly in series.
Huang teaches a roller shade comprising a first shaft (142) of a first spring assembly (138 on right in fig. 13) is configured to (capable of) directly couple to a shaft (146) defined by a connector (fig. 13), and a second housing (150) is configured to (capable of) directly couple to a locking member (right ends of 146) defined by the connector to connect the first spring assembly and a second housing. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention with a reasonable expectation of success to modify Costello with teachings of Huang so that the first shaft of the first spring assembly is configured to directly couple to the shaft defined by the connector, and the second housing of the second spring assembly is configured to directly couple to the locking member defined by the connector to connect the first spring assembly and the second spring assembly in series. This alteration provides the predictable and expected results of a strong connection between the components.
Regarding claim 2, modified Costello teaches that in response to rotation of the roller tube, the first shaft of the first spring assembly is configured to rotate, and wherein in response to rotation of the first shaft of the first spring assembly, the connector responsively rotates the second housing of the second spring assembly (paragraph 25 describes how force originating at B works its way to the roller tube. This works in the way claimed above in reverse with a force originating at the roller tube and working its way in the claimed manner to element B).
Regarding claim 3, modified Costello teaches that the first shaft (130 on 104) rotates relative to the first housing (described in paragraph 25).
Regarding claim 4, modified Costello teaches that the second housing (110 on 100) rotates relative to the second shaft (paragraph 25).
Regarding claim 5, modified Costello teaches that the first spring assembly and the second spring assembly are configured to apply a counterbalancing force to the roller tube (this is the force described in paragraph 25).
Regarding claim 6, modified Costello teaches a spring drive (110 on the left of fig. 6) received by the roller tube, the spring drive including a drive shaft (116), the drive shaft is configured to engage the first shaft (130 of 104) of the first spring assembly (per paragraph 25), and the spring drive is configured to engage the roller tube (paragraph 25).
Regarding claim 7, modified Costello teaches that in response to rotation of the roller tube, the spring drive is configured to rotate with the roller tube, the first shaft of the first spring assembly is configured to rotate in response to rotation of the spring drive, the connector is configured to rotate in response to rotation of the first shaft of the first spring assembly, and the second housing of the second spring assembly is configured to rotate in response to rotation of the connector (paragraph 25 describes how force originating at B works its way to the roller tube. This works in the way claimed above in reverse with a force originating at the roller tube and working its way in the claimed manner to element B).
Regarding claim 8, modified Costello teaches that the first shaft of the first spring assembly is configured to interlock with the shaft defined by the connector (see claim 1 rejection above, capable of).
Regarding claim 9, modified Costello teaches that the first shaft of the first spring assembly is configured to axially interlock with the shaft defined by the connector (see claim 1 rejection above, capable of).
Regarding claim 10, modified Costello teaches that the second housing (110 on 100) defines one of a projection (at left end near where arrow 56 is pointing in fig. 6), and the locking member (see claim 1 rejection above) defined by the connector defines a recess (near where the hook/ far right piece of element 146), the projection and recess are configured to interlock (capable of).
Regarding claim 11, Costello teaches a roller shade (figs. 5-8) comprising:
a roller tube (C);
a drive (110 and 116 on the left in fig. 6) received by the roller tube, the drive including a drive shaft (116) and a housing (110 on the left in fig. 6), the housing engaged with the roller tube (per paragraph 25);
a first spring assembly (104 is the first spring assembly) received by the roller tube, the first spring assembly including a first housing (each spring unit has a housing 110 per paragraph 25), a first shaft (each spring unit has a shaft 130) received by the first housing, a first spring member (each spring unit has a torsion spring 50) connected at one end to the first housing, and at an opposite end to the first shaft (as shown in fig. 7), wherein the first shaft is configured to rotate relative to the first housing (paragraph 25), and the first shaft is configured to engage the drive shaft of the drive (paragraph 25);
a second spring assembly (100) received by the roller tube, the second spring assembly including a second housing, a second shaft received by the second housing, a second spring member connected at one end to the second housing, and at an opposite end to the second shaft, wherein the second shaft is configured to rotate relative to the second housing (in the same way as the first spring assembly per paragraph 25); and
a series connection assembly (102) including a third housing (110) and a connector (132 and 134) defining a shaft (130) and a locking member (134), the connector received by the third housing (fig. 6), the connector configured to rotate relative to the third housing (paragraph 25),
Costello does not explicitly teach that the first shaft of the first spring assembly is configured to directly engage the shaft defined by the connector, and the second housing is configured to engage the locking member defined by the connector to connect the first spring assembly and the second spring assembly in series.
Huang teaches a roller shade comprising a first shaft (142) of a first spring assembly (138 on right in fig. 13) is configured to (capable of) directly engage a shaft (146) defined by a connector (fig. 13), and a second housing (150) is configured to (capable of) directly engage a locking member (right ends of 146) defined by the connector to connect the first spring assembly and a second housing. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention with a reasonable expectation of success to modify Costello with teachings of Huang so that the first shaft of the first spring assembly is configured to directly engage the shaft defined by the connector, and the second housing is configured to engage the locking member defined by the connector to connect the first spring assembly and the second spring assembly in series. This alteration provides the predictable and expected results of a strong connection between the components.
Regarding claim 13, modified Costello teaches that in response to rotation of the roller tube, the drive is configured to rotate with the roller tube, the first shaft of the first spring assembly is configured to rotate in response to rotation of the drive, the connector is configured to rotate in response to rotation of the first shaft of the first spring assembly, and the second housing of the second spring assembly is configured to rotate in response to rotation of the connector (paragraph 25 describes how force originating at B works its way to the roller tube. This works in the way claimed above in reverse with a force originating at the roller tube and working its way in the claimed manner to element B).
Regarding claim 21, modified Costello teaches that the second housing (110 on 100) defines a recess (opening on the left), and the locking member (right end of 146) defined by the connector defines a projection, the projection and the recess are configured to interlock (after the modification above).
Response to Arguments
Applicant’s arguments with respect to claim(s) 1 and 11 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
Applicant's arguments regarding claim 14 have been fully considered but they are not persuasive.
All the limitations as claimed are taught by the rather broad claim. For example, Costello teaches (figs. 5-8) a connection assembly (figs. 5-8) configured to connect a pair of roller shade springs in series comprising:
a connector (102) defining a plurality of projections (132 and 134, see fig. 8) and a recess (opening on left wall), the plurality of projections and the recess are oriented on opposing sides of the connector (as shown in fig. 8),
wherein the plurality of projections are configured to directly engage a spring (50) of a first spring assembly (100), and the recess is configured to receive and interlock with a housing (110) of a second spring assembly (106) to connect the first spring assembly and the second sporting assemble in series (see fig. 6a), and
wherein in response to rotation of the connector, the spring of the first spring assembly and the housing of the second spring assembly rotate (paragraph 25 describes how force originating at B works its way to the roller tube causing the required rotation).
