From the Boost License Requirements:

"Must grant permission without fee to copy, use and modify the
software for any use (commercial and non-commercial)."

I do not think that it necessarily conflicts with patents, as long as
you give every user of your program (and of derived work)
a royalty free license to use your patents [1], it might be ok, but
somehow I doubt this is what you had in mind.

Disclaimer: IANAL, ask a lawyer, etc...

HTH,

[1] which in practice makes the patent useless, with the notable of
exception of preventing others to patent the same idea.
