BACKGROUND
The invention relates to a method for marking workpieces for
identification with high quality barcodes and human-readable
information. Revised Appeal Brief (hereinafter “Appeal Brief”),
Paper No. 10, received December 30, 2002, page 7. The method
relies on a dual paint coat system wherein the workpiece is first
coated with a laser-blackenable paint. Claim 9. The basecoat is
partially cured with a laser beam to char the basecoat and
thereby form fragile product identification indicia thereon. Id.
Thereafter, the basecoat is overcoated with a clear topcoat which
protects the fragile product identification indicia while
allowing it to be seen. Id. According to appellants, the
inventive method overcomes the problem associated with prior art
methods wherein the fragile, dusty markings become smudged or
otherwise contaminated. Appeal Brief, page 8.
