What is Thermaltronics 'color band' patent?

[Corporate666]

Remember those old days metal pen refillfs with color marking on them?  They should easily cause a rejection due to prior art, though I doubt if that patent will be approved in the US anyway, due to obviousnes.

Those pens would have nothing to do with prior art - they are not soldering tips and the colors do not denote temperatures.  That they look similar is irrelevant.
