There's one major difference between OpenType and TrueType patents and
EOT: the browser is expected to "decrypt" (unscramble) the font file
(possibly needing the patent license) but OpenType and TrueType fonts
are used by the operating system. The browser vendors do not have
problem with those patents.

In addition, the patent(s) on EOT is meant to be used as "security"
feature preventing the "decryption" of font.
