Appeal No. 94-3599
Application 07/931,737
a) applying a liquid masking composition to a vehicle
flange;
b) painting the vehicle, and drying or curing the liquid
masking composition sufficiently to form a removable mask;
c) removing the mask from the flange; and
d) adhesively bonding the vehicle window to the vehicle
flange.
In addition to the admitted state of the prior art found in
appellant's specification, the examiner relies upon the following
references as evidence of obviousness:
Hong et al. (Hong) 4,125,088 Nov. 14, 1978
Kano et al. (Kano) 4,871,585 Oct. 3, 1989
Appellant's claimed invention is directed to bonding a
window to a vehicle flange. The process entails applying a
liquid masking composition to the flange, painting the vehicle
and drying or curing the masking composition, removing the mask,
and adhesively bonding the window to the flange. According to
appellant, utilizing a liquid masking composition prior to
painting the vehicle is an improvement over the prior art method
of applying a solid pressure sensitive adhesive tape to the
vehicle flange. Appellant maintains that the claimed invention
obviates the disadvantages of the prior art method, which is
labor intensive, not effectively automatable, and leaves a
residue which may impair the adhesive strength between the window
and the flange.
