Microsoft published their UProve technology to an open source license; however they mention that they can't guarantee that the technology does not infringe on other patents not covered by Microsoft.

What known patents can cause an issue for implementors of UProve technology?

Does it matter if UProve is configured to exclusively rely on "Subgroups" versus the patent minefield of ECC?

General discussion of Microsoft and/or open-source is probably off topic here. If you can edit your question to be more clear including patent number(s), it may help. – Ron J. Jun 29 '13 at 13:57
@RonJ. I am only asking because the last patent Q I asked on Sec.SE was migrated here – LamonteCristo Jun 29 '13 at 15:27
A disclaimer that says "we are giving you X rights for free to use what we own but can't guarantee that using it won't infringe something we don't own" seems like a very sensible thing whether or not they have something specific in mind. – George White Jun 29 '13 at 17:05
@RonJ -- if you have specific patents and subject matter in mind, then list the patent and the concern and ask for examples of prior art -- – Soren Aug 26 '14 at 12:22
