The page at

	http://www.freetype.org/patents.htm

lists these:

*	Patent #1 :Ê US5155805: Method and apparatus for moving control points in displaying digital typeface on raster output devices
Filed on May, 8 1989 

*	Patent #2 : US5159668: Method and apparatus for manipulating outlines in improving digital typeface on raster output devices
Filed on May, 8 1989 too. Actually, the two patents were filed and granted concurrently. 

*	Patent #3 : US5325479: Method and apparatus for moving control points in displaying digital typeface on raster output devices
Filed on May 28, 1992Ê which is the continuation of patent #1. The difference with this patent are extremely subtle, and we fail to see what it covers which isn't in patent #1.
