Software Patents on Memory Allocators?
Emery Berger asks:
"I'm a PhD. student at the University of Texas and the author of
Hoard, an open source memory
allocator for multiprocessors.
After posting information about the latest pre-release to the Hoard
mailing list, I received a cease-and-desist
letter from Microquill, Inc., which markets memory management software,
calling for me to stop distributing Hoard. They are claiming that my
latest version of Hoard, which does DLL patching when running on
Windows, infringes on their patent (which actually dynamically
rewrites arbitrary executables). Because DLL patching is prior art
and my technique is quite different from theirs, I think I'm in the
clear. However, if anyone knows of systems from 1996 or earlier based
on DLL patching (or any dynamic rewriting of a running executable),
especially to change the memory allocator, that would really
help."
Have you considered asking the GC mailing list? http://lists.tunes.org/mailman/listinfo/gclist
...
Coincidentally, there have been a couple of recent queries on gclist asking about patents on GC and memory management algorithms
