Antitrust law is not solving the problems
History has shown that antitrust law and other laws to protect competition don't work against problems caused by patents.
In the EU case against Microsoft, which Microsoft lost, the final settlement allows Microsoft to use its software patents against all commercial software projects, including commercial projects that develop free software.
The US case is less clear. It involves hardware manufacturers, so the existence of patent royalties isn't a crunch issue (unlike software where it breaks common software distribution models). The case in question is the Federal Trade Commission's case against Rambus provides a complicated example, without much good news. (This is well described on Wikipedia: Rambus#Lawsuits
