Yes, it might not matter however. Another algorithm that was written by university folk (thus probably not patent prone) that looks promising is: http://www.cs.wm.edu/hpcs/WWW/HTML/publications/papers/TR-02-6.pdf http://parapet.ee.princeton.edu/~sigm2002/papers/p31-jiang.pdf (same, but better typeset)
It even seems to slightly beat ARC according to the MQ paper.

Do not assume that University algorithms are not patent protected. They definitely may be and I know they sometimes are.
Princeton has an office dedicated to the issue: http://www.princeton.edu/patents/
