Office Action

§102
DETAILED ACTION Application Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . This action is in response to Applicant’s submission dated 09/07/2026. Claim(s) 1–13 are pending. Election/Restrictions Applicant's election with traverse of Group I: claims 1–4 & 11–13 in the reply filed on 09/07/2026 is acknowledged. The traversal is on the ground(s) that claims 11–13 (Group I) & 5 (Group II) contain a feature which is not disclosed by CN 108662588. This is not found persuasive because claim 1 is generic to both groups and is disclosed by the prior art. The special technical feature asserted by Applicant (flue gas conveying chamber) is not present in all the claims of Group I. The requirement is still deemed proper and is therefore made FINAL. Applicant is reminded, however, that should claim 1 be determined to be allowable, the restriction requirement can be withdrawn and the non-elected claims rejoined since they depend from claim 1. 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 1 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by US 3,807,322 to Liu et al. With regard to claim 1, Liu discloses a biomass gasification and waste incineration integrated furnace (abstract), comprising a waste incineration furnace chamber (38) and a biomass gasification furnace chamber (12) (Fig. 1; Col. 2, lines 14–19; Col. 2, line 65– Col. 3, line 1; “biomass” is a subset of “waste materials”); wherein a mutual contact region (36) exists between the waste incineration furnace chamber (38) and the biomass gasification furnace chamber (12) (Fig. 1), and heat generated in the waste incineration furnace chamber (38) is transferred to the biomass gasification furnace chamber (12) for enabling reaction inside the biomass gasification furnace chamber (12) (Fig. 1; Col. 2, lines 50–55). Allowable Subject Matter Claims 2–4 & 11–13 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. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: see attached PTO-892. Applicant is encouraged to review the cited references prior to submitting a response to this office action.
