While this is a nice hack the usual protections of having patents belong to an non- practicing entity would still work, i.e. this sadly won't work against patent trolls, only against honest companies.

Unless the trolls had bought the patents from a company that had assigned themselves a license.

As far as I'm aware, its quite common to retain rights to a patent portfolio, when selling it on.
