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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 08/25/26 has been entered.
All claims are drawn to the same invention claimed in the application prior to the entry of the submission under 37 CFR 1.114 and could have been finally rejected on the grounds and art of record in the next Office action if they had been entered in the application prior to entry under 37 CFR 1.114.
Accordingly, THIS ACTION IS MADE FINAL even though it is a first action after the filing of a request for continued examination and the submission under 37 CFR 1.114. See MPEP § 706.07(b).
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 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.
If 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.
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.
The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
Determining the scope and contents of the prior art.
Ascertaining the differences between the prior art and the claims at issue.
Resolving the level of ordinary skill in the pertinent art.
Considering objective evidence present in the application indicating obviousness or nonobviousness.
When something is indicated as being “obvious” this should be taken as shorthand for “prima facie obvious to one having ordinary skill in the art to which the claimed invention pertains before the effective filing date of the invention”.
When a range is indicated as overlapping a claimed range, unless otherwise noted, this should be taken as short hand to indicate that the claimed range is obvious in view of the overlapping range in the prior art as set forth in MPEP 2144.05, in the case where the claimed range “overlap or lie inside ranges disclosed by the prior art”, a prima facie case of obviousness exists, In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976); In re Woodruff, 919 F.2d 1575, 16 USPQ2d 1934 (Fed. Cir. 1990).
Claim(s) 1-4, 6-7, 9-12, 14-15, 17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Endo (WO 2015/068859) in view of Mizuno et al. (U.S. 2011/0097579) in view of Michio et al. (WO 2018/096858, see machine translation) in view of Kuroda (U.S. 2018/0118988) with evidence from the X-40-2450 NPL document.
Regarding claims 1-4, 6-7, 9-12, 14-15, 17, Endo teaches a silicone based composition that forms an adhesive and releasable protective film (adhesive because it may contain adhesion promoters, as in claim 15, [0059], releasable as in the title, and inherently protective to at least some degree), wherein the composition comprises a mixture of polysiloxanes (corresponding to the claimed i and ii ingredients as explained below) at an amount overlapping claim 14 and 17, as well as a hydrosilane functional crosslinker and a corresponding catalyst ([0010]). Endo also suggests antistatic agents ([0059]).
Endo teaches that the a1 component overlaps the claimed i component when all terminal R/R11 groups are methyl, non-terminal R11 groups are methyl, and Ra is a C4-C10 alkenyl as claimed ([0027]-[0029]), and teaches that the a2 component overlaps the claimed ii component when the R and the terminal R11 groups are vinyl and/or methyl (or all vinyl), m is zero, and the non-terminal R11 groups are methyl ([0035]).
Endo discloses an ai:aii ratio that is slightly outside the claimed ranges ([0025], i.e., 50:50 a1:a2 of Endo vs 45:55 i:ii of claim 17 or the 40:60 i:ii of claim 14). However, Endo further disclose the B ingredient may be a linear polydimethylsiloxane with ends capped with vinyl groups (thus qualifying as the claimed ii ingredient) and may be included at a 90:10 ratio of A:B (with A being the sum of ai and aii) ([0041]-[0048]). Thus, if there was 45 parts of ai and 45 parts of aii (making a 50:50 ai:aii ratio as discussed above), at a 90:10 ratio of A:B there may be 45 parts of ai (corresponding to i as claimed) and 55 parts (i.e., 45+10) of aii and B (corresponding to aii as claimed). This 45:55 ratio is within the scope of claim 17 and only slightly outside the 40:60 ratio of claim 14. Furthermore, component B is provided with an effective result to the overall composition (ease of application, [0041]) such that the amount of component B relative to component A may be adjusted/optimized (including to higher amounts of B relative to A than 90:10) based on the desired ease of application.
In addition to the above remarks explaining how the i:ii ratio is obvious over Endo in view of overlapping ranges and/or result effective variable optimization of A:B, the claimed i:ii ratio is further obvious based on MPEP 2144.05 II A. Generally, differences in concentration or temperature will not support the patentabilitxy of subject matter encompassed by the prior art unless there is evidence indicating such concentration or temperature is critical. “[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation.” In reAller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955) (Claimed process which was performed at a temperature between 40°C and 80°C and an acid concentration between 25% and 70% was held to be prima facie obvious over a reference process which differed from the claims only in that the reference process was performed at a temperature of 100°C and an acid concentration of 10%.); see also Peterson, 315 F.3d at 1330, 65 USPQ2d at 1382 (“The normal desire of scientists or artisans to improve upon what is already generally known provides the motivation to determine where in a disclosed set of percentage ranges is the optimum combination of percentages.”); In reHoeschele, 406 F.2d 1403, 160 USPQ 809 (CCPA 1969) (Claimed elastomeric polyurethanes which fell within the broad scope of the references were held to be unpatentable thereover because, among other reasons, there was no evidence of the criticality of the claimed ranges of molecular weight or molar proportions.). For more recent cases applying this principle, see Merck & Co. Inc.v.Biocraft Lab. Inc., 874 F.2d 804, 809, 10 USPQ2d 1843, 1848 (Fed. Cir. 1989), cert. denied, 493 U.S. 975 (1989)(Claimed ratios were obvious as being reached by routine procedures and producing predictable results); In reKulling, 897 F.2d 1147, 1149, 14 USPQ2d 1056, 1058 (Fed. Cir. 1990)(Claimed amount of wash solution was found to be unpatentable as a matter of routine optimization in the pertinent art, further supported by the prior art disclosure of the need to avoid undue amounts of wash solution); and In re Geisler, 116 F.3d 1465, 1470, 43 USPQ2d 1362, 1366 (Fed. Cir. 1997)(Claims were unpatentable because appellants failed to submit evidence of criticality to demonstrate that that the wear resistance of the protective layer in the claimed thickness range of 50-100 Angstroms was “unexpectedly good”); Smith v. Nichols, 88 U.S. 112, 118-19 (1874) (a change in form, proportions, or degree “will not sustain a patent”); In re Williams, 36 F.2d 436, 438, 4 USPQ 237 (CCPA 1929) (“It is a settled principle of law that a mere carrying forward of an original patented conception involving only change of form, proportions, or degree, or the substitution of equivalents doing the same thing as the original invention, by substantially the same means, is not such an invention as will sustain a patent, even though the changes of the kind may produce better results than prior inventions.”). See also KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 416, 82 USPQ2d 1385, 1395 (2007) (identifying “the need for caution in granting a patent based on the combination of elements found in the prior art.”).
Endo does not disclose the claimed organic polysiloxane resin. However, Mizuno is also directed to a siloxane composition that is hydrosilation curable and has adhesive and release properties, and teaches that such a composition may have controllable adhesion and still be able to release from an adherend without leaving residue by including an MQ organosiloxane resin overlapping claims 1, 3, 4, 10, 11, which contributes to adhesiveness (recall that Endo calls for adhesion promoters) ([0014], [0072]-[0076]), such that it would have been obvious to have included such an MQ resin in the composition of Mizuno in order to control the adhesiveness of the composition while still allowing for release properties as sought by Endo.
Although the amount of the MQ resin is not disclosed as in claim 12, the amount of the MQ resin is art-recognized as affecting the adhesiveness of the composition and thus would have been obvious to adjust, including to values within the claimed range, as part of the optimization of the degree of adhesion of the composition as taught by Mizuno. Similarly, the degree of adhesion (e.g., peel strength as in claim 2) is obvious to optimize in modified Endo, including to values within the claimed range, because modified Endo seeks a composition that has adhesion and release properties (i.e., such that the degree of adhesion would be obvious to optimize as part of balancing adhesion vs release). Furthermore, because claim 2 does not specify the type of adherend or the testing parameters, the limitation may be met simply by selecting a suitable adherend that will produce a peel strength within the claimed range.
Modified Endo does not disclose the claimed ionic siloxane compound but does call for antistatic agents. However, Michio is also directed to hydrosilation curable silicone compositions that include an overlapping amount (as in claim 9) of antistatic additives and teaches that silicone based antistatic additives are preferred in terms of dispersibility in a silicone based composition, and suggests additives that are silicone modified ionic liquids, such as X-40-2450 ([0029]). As evidenced by the X-40-2450 NPL document, this additive has a siloxane group bound to an cation of a conjugated anion-cation ionic liquid group, as in claim 6, and is “non-curing” (see the fourth line in the table on the last page, thus does not include alkenyl groups, as in claim 7). Thus, it would have been obvious to have used a non-curing siloxane modified ionic liquid type antistatic agent, like X-40-2450, as taught by Michio, in order to improve dispersibility in siloxane based compositions like in modified Endo. Although the amount of antistatic additive in Michio overlaps claim 9 as indicated above, this would also be obvious to modify to within the claimed range as an art-recognized result effective variable for optimize antistatic properties.
Although the particular anion and cation of the ionic liquid part of the silicone modified ionic liquid are not disclosed in Michio of modified Endo, Kuroda is also directed to hydrosilation curable silicone compositions that include ionic liquids to provide antistatic properties and teaches that imidazolium is a suitable cation and bis(trifluoromethylsulfonyl)imide is a suitable anion (corresponding to the elected species) ([0052]-[0054]). Thus, it would have been obvious to have used these anion and cation species for the siloxane modified ionic liquid in modified Endo, because Kuroda teaches that they are suitable for the desired intended purpose (i.e., to provide antistatic anions and cations in a hydrosilation curable silicone composition).
Regarding claims 3 and 4, modified Endo does not disclose the claimed properties, however, given that modified Endo teaches an overlapping type of composition compared to the composition that achieves these properties in the present application, these overlapping embodiments in modified Endo will inherently have the same properties as the overlapped embodiments of the present application.
Claim(s) 5 is/are rejected under 35 U.S.C. 103 as being unpatentable over Endo (WO 2015/068859) in view of Mizuno et al. (U.S. 2011/0097579) in view of Michio et al. (WO 2018/096858, see machine translation) in view of Kuroda (U.S. 2018/0118988) with evidence from the X-40-2450 NPL document, as applied to claim 1 above, and further in view of Nagashima (U.S. 2015/0152295).
Regarding claim 5, modified Endo discloses all the above subject matter but does not disclose the claimed surface resistance. However, Nagashima is also directed to antistatic silicone based compositions and teaches that the antistatic properties correspond to surface resistance and a desirable surface resistance overlaps claim 5 to provide antistatic properties ([0032], [0042]) such that it would have been obvious to have used such a surface resistance for the coating of modified Endo because it corresponds to a good antistatic property as taught by Nagashima.
Response to Arguments
Applicant’s remarks are not persuasive.
The previous 112 1st rejection is withdrawn due to Applicant’s amendment.
The art-based rejection above is the same as previously presented (besides changing present claim references) and thus this action is final. It is noted that an after final amendment based on MW (07/09/26) was not entered in the advisory action of 07/16/26, however, that amendment was not adopted in the RCE of 08/25/26 (the RCE amendment has no such MW limitation, nor any other limitation that has not already been considered and addressed in the previous rejection). Thus, this action is final.
Applicant argues that the elected species of siloxane ionic compound is not obvious over the cited references because Kuroda discloses “free” ionic liquids, not siloxane bonded ionic liquids. First, this is improper piecemeal analysis because Kuroda is cited merely for the suitable types of cation and anions for the generic siloxane bonded ionic liquid already disclosed and rendered obvious by Michio (i.e., Michio renders obvious ionic group bonded silicone oligomers as antistatic agents with good dispersability in silicone compositions and good heat resistance, but fails to disclose particular ionic groups, which would lead one of ordinary skill in the art to seek out such suitable groups, as taught by Kuroda).
Second, Applicant’s citation to [0039] in Kuroda does not teach away from using the ionic groups as the ionic groups in the siloxane oligomer of Michio because there is nothing in this citation that disparages such a use of the ionic groups (i.e., nothing disparages binding the ionic groups to a siloxane oligomer). To the contrary (and contrary to Applicant’s “free” ionic group characterization of Kuroda), the cited paragraph actually describes binding the ionic groups (i.e., “capture”) analogous to how the ionic groups are captured/bonded to the siloxane oligomer in Michio. Furthermore, the effect of this ionic group “capture” in Kuroda is similar to the desired effect in Michio. In Kuroda, the “capture” is described as allowing the ionic groups to “move,” and in Michio the siloxane bonded ionic groups have improved “dispersability.” Thus, the citation to Kuroda actually strengthens the combination with Michio. But even if the cited portions were not strengthening (arguendo), they are certainly not teaching away from the mechanism/use of ionic groups bound to siloxane oligomers as taught by Michio.
Applicant then argues that it is not obvious to select the particular ionic groups from Kuroda to match those being claimed. However, the list of cations in Kuroda only include five members ([0053]) and while the list of anions is longer (still not so long as to render any particular species non-obvious), the elected sulfonyl imide anion is the preferred anion ([0054]). Thus, it is entirely obvious to select these particular species from Kuroda.
Applicant also provides a five step modification to make the combination of Michio based on Kuroda seem non-obvious. However, even the five steps provided by Applicant do not make the proposed modification non-obvious. Moreover, the modification based on Kuroda is more appropriately described as “select an ionic group containing silicone oligomer from the two preferred options in Michio (i.e., silicone oligomers and alkali metal salts), then find suitable anions and cations for the generic ionic groups in the silicone oligomer based on Kuroda”. Applicant refers to “disregarding” the undisclosed ionic chemistry of the commercial oligomer but this commercial product was merely cited to show that Michio was referring to cations and anion pairs when referencing “ionic groups.” The rejection was not limited (nor is Michio limited) to those particular commercial products.
Applicant then argues that there is no teaching regarding “how or why” the ions from Kuroda would be incorporated into the silicone oligomer of Michio. First, regarding “why,” this would obviously be to provide the desired antistatic property resulting from ion pairs as called for by Michio. Second, regarding “how,” the prior art is presumed to be enabled and Michio clearly does not see any need to describe how ionic groups are bound to a siloxane oligomer such that it is presumed within the ordinary skill of the art. This is confirmed by the commercial products being able to bound ionic groups to a siloxane oligomer and is further confirmed by Applicant’s own disclosure failing to provide any detailed mechanism or instructions on how to bind particular ionic groups to a siloxane oligomer. Taken together, this evidence shows that one of skill in the art would know how to bond ionic groups in general (and the elected species in particular) to a silicone oligomer (otherwise the present disclosure would lack enablement).
Regarding Applicant’s argument that the particular species were not know to maintain the dispersability, heat resistance, or antistatic performance benefits taught by Michio, it is noted that only one of such benefits is necessary to make the above modification obvious. As explained above, ionic compounds are known to provide antistatic properties via their ionic charges. Furthermore, Michio’s dispersibility improvement in the silicone composition would have been obviously (to one of ordinary skill in the art) due to the ionic groups being bound to a silicone oligomer that is similar (chemically) to the other silicone ingredients in the overall composition, thus allowing easy dispersion/movement of the ionic groups through the silicone matrix. Likewise, one of ordinary skill in the art would recognize that heat resistance is a property attributed to silicone polymers in general and would be attributed to the silicone structure of the overall antistatic agent. Nothing about the particular ionic groups in Kuroda would be expected to affect, let alone negate, the above benefits attributed to the siloxane bound ionic groups from Michio (especially not all three of the above benefits).
Conclusion
All claims are drawn to the same invention claimed in the application prior to the entry of the submission under 37 CFR 1.114 and could have been finally rejected on the grounds and art of record in the next Office action if they had been entered in the application prior to entry under 37 CFR 1.114. Accordingly, THIS ACTION IS MADE FINAL even though it is a first action after the filing of a request for continued examination and the submission under 37 CFR 1.114. See MPEP § 706.07(b). 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 extension fee 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.
