Appeal No. 1999-0737
Application 08/655,176
DECISION ON APPEAL
This is a decision on appeal from the examiner’s refusal to allow claims 1-6, 8-14, 16-21, 23-
25 and 27-29 as amended subsequent to the final rejection in a document filed March 30, 1998 (Paper
No. 10). Claims 7, 15, 22 and 26, the only other claims remaining in the application, 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. Claim 30 has been canceled.
Appellants’ invention is directed to a roofing membrane heat seal indicator which provides a
positive, visually perceptible indication that a seam has been raised to a sufficiently high temperature to
achieve a proper seal. Independent claim 1 is representative of the subject matter on appeal and a
copy of that claim, as reproduced from the Appendix to appellants’ brief, is attached to this decision.
The prior art references of record relied upon by the examiner in rejecting the appealed claims
are:
Wahl et al. (Wahl) 3,002,385 Oct. 3, 1961
Spirg 4,459,046 July 10, 1984
Takahara et al. (Takahara) 4,601,588 July 22, 1986
Stamper et al. (Stamper) 4,827,686 May 9, 1989
Appellants’ admitted prior art, found on page 1, lines 26-33 of the instant specification is also relied
upon by the examiner.
