Claim Rejections - 35 USC § 103
The text of those sections of Title 35, U.S. Code 103 not included in this action can be found in a prior Office action.
Claim(s) 15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Romanchik in view of Chen et al. (U.S. 4,904,245) and Makihara et al. (U.S. 5,983,937).
Romanchik discloses the claimed structure and further discloses wherein the main body of the valve core is of a cylinder structure (see figs. 2-4), the valve core is of a one-piece structure (24 is shown as a single piece), and the valve core comprises a valve core shaft (26, 28).
Romanchik does not appear to disclose the one-piece structure made by injection molding or a component to be detected and a detector, the component to be detected is located at an end of the valve core shaft and is fixedly connected to the valve core shaft, and the detector is configured to cooperate with the element to be detected to detect a position of the valve core.
To the extent that the applicant recites the limitation of injection molding, this is viewed as a product-by-process claim and has not been given patentable weight; however, the limitation is seen to require the material of the core to be capable of being injection molded.
Chen teaches it was known in the art to have a similar valve core (34) that is a one-piece structure made by injection molding (figs. 5-10, see col. 2, ll. 33-34 describing the core being made of plastic that is molded which is seen to be capable of being injection molded).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify Romanchik by having the core be made of plastic that is able to be injection molded as taught by Chen in order to have the material of the core be of a relatively inexpensive, easy to acquire and manufacture material and especially as it has been held that the selection of a known material on the basis of its suitability for an intended use involves only routine skill in the art. See MPEP2144.07.
Makihara teaches it was known in the art to have a similar rotary valve (8) with a shaft (108) that is part of the rotary valve and a component to be detected (20) and a detector (ECU 21), the component to be detected is located at an end of the valve core shaft and is fixedly connected to the valve core shaft (fig. 3, connected at 8c, see also col. 7, ll. 6-9), and the detector is configured to cooperate with the element to be detected to detect a position of the valve core (col. 7, ll. 6-9, 17-25).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the rotary valve of Romanchik by having a shaft for the core and a position detector located at the end of the shaft and fixedly connected to the shaft as taught by Makihara in order to be able to detect the position of the valve so that the various flow paths can be determined and changed if so desired by a user to connect the various ports and allow fluid communication amongst the different downstream and/or upstream components.
Allowable Subject Matter
Claims 4-14, and 18-20 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
Response to Arguments
Applicant's arguments filed 9/25/2026 have been fully considered but they are not persuasive.
At the top of page 11 of the response, applicant argues that in applicant’s figures 5 to 8, M = 3, which includes communication chambers 321 to 323. This argument is noted. However, applicant’s claim recites M ≥ 2. In other words, the applicant is claiming M is greater than or equal to 2. As described in at least the third line of the rejection of claim 3 on page 8 of the Non-Final Rejection dated 9/25/2026, M communication chambers total 2, elements 25 and 27, in the Romanchik reference. As such, Romanchik is seen to satisfy the limitation of M ≥ 2, as M is equal to two (and as applicant states at the top of page 12 of the response). The examiner has clarified this in the rejection above. It is noted that M equaling two total communication chambers was included in the third line of the rejection of claim 3 on page 8 of the Non-Final Rejection dated 9/25/2026, i.e. “provided with M communication chambers (25, 27)” and the fourth to last line of the rejection of claim 2, i.e. “M>N (fig. 2, M totals two (25 and 27) and there is only one flow path, between 16 and 14)”.
For at least the above reason(s), applicant’s arguments have not been found persuasive.
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.
