True Type Fonts.

Perhaps, but one of the purposes of holding a patent is give one grounds for
dragging ones opponents into lengthy and, most important, expensive legal
battles, the purpose of which is to distract the opponent and drain their
resources.  If someone who is reasonably well funded, such as Apple, takes
it into their collective heads to squash a freeware provider based on patent
infringement, I do not doubt that they can.  They don't have to win the case
on its merits - they just have to delay, delay, delay until the target of
their ire runs out of money.  Then they win.
