Dear All,

SEcure Neighbor Discovery (SEND) is a Standards Track which is defined in
RFC 3971.
It is a subject to patent US 2008/0307516 A1 (
http://www.freepatentsonline.com/y2008/0307516.html )

My question is how RFCs implementations become Patents while it is open for
all? What are the consequences of having patents for network protocols?

We implement SEND for Windows (WinSEND) (

Could we have a patent for "WinSEND" or even make it a product?
