[IronPython] Patent concerns

The answer to that probably requires a patent lawyer, and since we've each been trained in the mantra, "I am not a lawyer", it follows that "We are not patent lawyers."  This is particularly true when talking amongst developers, since what we might consider patentable and not varies dramatically from what Legal would advise.

So, short of someone from MS Legal chiming in, I would (personally) advise interested parties to consult their own (professional) legal counsel.

Subject: [IronPython] Patent concerns


Recently on jvm-languages list, which is an interest group surrounding
language implementation for the JVM, Frank Wierzbicki from Jython
project expressed the concern that Microsoft may hold a lot of patents
related to IronPython, so he is reluctant to look at the source code
even if it is open-sourced.


Apparently, this seems to be a widespread concern. I think this is a
pity, since in my opinion IronPython has a lot of good ideas that
would benefit language implementations on JVM.

So, please answer if possible. What patents Microsoft hold, related to
