Do you mean XORing (exclusive-orring) the destination pixels with a source
all of whose bits are 1s?  What if one simply uses bitwise NOT?

I find it hard to believe that bitmap graphics could have existed longer
than 5 minutes (well, maybe 5 weeks) before someone used either NOT or
XOR to produce text in inverse video.  This patent doesn't sound very
enforceable to me.
