Re:I just read the patent... (Score 1)

To add to the above observations, the patent only seems to refer to a single (1) computer apparatus, not an network of computers, and it always says that the "hidden" part is the SECOND part of the block. In contrast, most of the time HTML hyperlinks have the "hidden" stuff first, for example:
<a href="http://slashdot.org">Slashdot</a>
These would be nitpicks to a programmer, but might be significant to the judicial system!
