Appeal 2007-2549
Application 10/163,206
The rejections on appeal are: Claims 1-14 and 20-25 stand rejected
under 35 U.S.C. § 103(a) as obvious over Broekhoven in view of Yigong.
Claims 15-19 stand rejected under 35 U.S.C. § 103(a) as obvious over
Broekhoven in view of Yigong, as applied to claims 1 and 2, and further in
view of Holmes.
Appellants have not argued any of claims 1-25 as separately
patentable inventions (Br. 3-6). Therefore, we decide this appeal on the
basis of claim 1, the only independent claim involved in the appeal. 37 CFR
§ 43.37(c)(1)(v).
II. Findings of Fact (FF)
The following findings of fact are supported by a preponderance of
the evidence of record. To the extent any "finding of fact" is a conclusion of
law, it should be so treated.
A. Appellants' specification
[1] The specification describes a process comprising (i) reacting an
alkylatable compound with an alkylation agent over a solid acid
alkylation catalyst to form an alkylate, and (ii) regenerating the
catalyst under mild regeneration conditions in the presence of
hydrogen and a hydrocarbon which comprises at least a portion of the
formed alkylate (Specification 3:1-7).
[2] Preferred alkylatable compounds are isoalkanes having 4-10 carbon
atoms, e.g., isobutane, isopentane, isohexane or mixtures thereof
(Specification 13:1-3).
[3] Preferred alkylation agents are olefins having 2-10 carbon atoms, e.g.,
propene, butene or pentene (Specification 13:5-7).
