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 .
Response to Amendment
The new grounds of rejection set forth below are necessitated by applicant’s amendment filed on December 10, 2025. In particular, claim 1 which has been amended to further limit the R1 and R2 groups of the polyester polyol as well as limit the molecular weight of the polyester polyol. Also, claim 12 is newly presented. This combination of limitations was not present at the time of the previous office action. Thus, the following action is properly made final.
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, 4-5 and 12 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Brandt et al (WO 2019/081075 please refer to US 2020/0239751 for English language equivalent).
Regarding claims 1-2, 4 and 12, Brandt teaches a composition comprising: a multifunctional isocyanate compound such as 4,4’-MDI ([0061]) which is a diisocyanate and a polyester polyol which comprises: adipic acid (which reads on the m subunit of Formula I), 2,5 furandicarboxylic acid (which reads on the n subunit of Formula I) and diethylene glycol. Table 1 indicates that the composition of the polyol is adipic acid : furandicarboxylic acid : ethylene glycol in a ratio of 1:1:2. Based on this reaction, R1 has (from the ethylene glycol) 2 carbon atoms, R2 has (from the adipic acid) 4 carbon atoms, R3 and R4 are (from the furandicarboxylic acid) hydrogen atoms.
The molecular weight of adipic acid is 146.14, the molecular weight of furandicarboxylic acid is 156.09 and the molecular weight of ethylene glycol is 62.7. The molecular weight of the polyol is 2,945 g/mol ([0055]). Given these parameters, m and n are equal and are approximately 7.
Regarding claim 5, Brandt teaches that the polyol and the isocyanate are added separately from each other into a reactor ([0060]-[0061]) and therefore, can be considered to be in two different packets without the other component in the packet.
Response to Arguments
Applicant's arguments filed December 10, 2025 have been fully considered but they are not persuasive for the reasons set forth below:
Applicant’s argument: Brandt does not teach or suggest the composition of claim 1, as amended.
Examiner’s response: Brandt does appear to still read on the amended claims. The mapping to the limitations is noted above.
Conclusion
THIS ACTION IS MADE FINAL. 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.
