According to http://bugs.ghostscript.com/show_bug.cgi?id=690621 , we can safely enable the bytecode interpreter in Fedora and all the code covered by those patents. They have expired since May, 2010.
Legal, is this safe? Can we make a quick import of the RPM Fusion package into Fedora?
They expired in October 2009 in fact.
We enabled them, but had to disable since it caused regression with autohinting stuff. There's a bug filed about it with lots of history, can't find it right now.
This bug appears to have been reported against 'rawhide' during the Fedora 14 development cycle.
Changing version to '14'.
More information and reason for this action is here:
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
The patented bytecode is with us since Fedora 15 Beta.
