openSUSE Hobbled By Microsoft Patents
kripkenstein writes "openSUSE 10.2 no longer enables ClearType (which would improve the appearance of fonts). The reason given on the openSUSE mailing list for not enabling it is, 'this feature is covered by several Microsoft patents and should not be activated in any default build of the library.'
As reported on and discussed, this matter may be connected to the Microsoft-Novell deal. If so, Novell should have received a license for the Microsoft patents, assuming the deal covered all relevant patents. Does the license therefore extend only to SUSE, but not openSUSE?"
Steve Gibson pointed out decades-old prior art that would invalidate the Cleartype patent (if our patent system weren't corrupt) several years ago.
I too have felt the cold finger of injustice.
I think Novell has become an wholly owned subsidiary of MSFT and is being used for the express purpose of setting up precedents and creating more and more FUD. I have seen a version of anti-aliasing and sub-pixel addressing way back when in, of all places, grc.com.

Cleartype is just sub-pixel AA which existed long before MS ever used it for font rendering. Bytecode type hinting is patented by (IIRC) Apple, it is usually disabled in Freetype and and an alternative (auto-hinting) method used instead.
Apples and oranges, the bug reporter is confused or trolling.
AFAICT, subpixel rendering is not disabled, only the 5-tap filter that's supposed to reduce colour fringes. See http://www.grc.com/cttech.htm. Apparently this is one of the things Microsoft has patented, and I haven't seen any "prior art" for this specific technique. In my humble opinion disabling the filter is not much of a loss as it just makes fonts look fuzzier.
The main developer of FreeType decided to disable the filter in September. The Novell deal was later and had nothing to do with this.
