Of course not. But it _will_ effect our abillity to attract companies.
Eventually I think the courts, possibly with the help of the politicians will realize that only a very weak doctrine of derived work could every service society without introduces needless uncertainties and/or absurdities.
For example I think that some cases where the doctrine of derived work has been used like IIRC in some case considering unauthorised Star Trek books. Using the Star Trek characters in a book without Paramounts(?) permission, would be much better served using trademark law instead. This might or might not require changing trademark law but that is a different issue.
Don't expect it to happend soon though.
