Those patents haven't expired yet.
http://www.freetype.org/patents.html"The colour filtering algorithm of Microsoft's ClearType technology for subpixel rendering is covered by patents. Note that subpixel rendering per se is prior art; using a different colour filter thus circumvents Microsoft's patent claims."
Maybe we could just change the color filter to a lighter gray to avoid patent issues?
http://www.grc.com/ctwho.htm is also good. Thanks! -- Alex
