I do not think so ! Did you really tried to implement it...
It is not that straightforward because of phase and windowing problems,
a solution to these problems is proposed in the patent, that is what the
patent
is about, not simple IFFT.
Please, read the patent before saying...

When it is straightforward and you can proove an anterior realisation of
the invention, then, no problem, you can bring an action against it and
cancel it.

Some patents are stupid  (I cited some insipid patents some months ago), in
which case you can cancel them. Some patents are not stupid and really solve
problems. These patents are valid and the inventors deserve the money they
can obtain with it... You are free to negociate with the inventors to obtain
a license.
