Los Angeles, California, Antitrust Dispute Lawyer

The primary purpose of the federal and state antitrust laws is to promote and preserve competition. Actions and practices that prevent or restrict competition are illegal under the antitrust laws. Among the prohibited practices are price fixing among competitors, allocation of markets by competitors, bid rigging, certain tying arrangements and monopolistic practices. Business owners and consumers may be victimized by practices that violate the antitrust laws. Antitrust laws can be a minefield for business owners who attempt to do the right thing but inadvertently violate the antitrust laws.

There are a number of recognized defenses to claims brought under the antitrust laws. Potential plaintiffs must take these defenses into account when deciding whether to bring actions and when drafting complaints. Defendants must be aware of potential defenses when defending against antitrust claims.

  • Joint Ventures
  • Preemption Doctrine
  • Filed Rate Doctrine

Are antitrust claims that you are defending or thinking of bringing barred by the doctrines of preemption and filed rate? The subtle and complex doctrines of preemption and filed rate limit and restrict the application of federal and state antitrust and unfair competition laws in diverse and complex ways. These doctrines have to be taken into account when determining whether or to what extent federal antitrust and unfair competition laws apply to industries that are subject to federal and state regulatory statutes and administrative agencies. The doctrines of preemption and filed rate are applied differently by courts depending on whether industries are subject to the jurisdiction of a federal or state agency. The federal and state regulatory mechanisms must be examined on an industry by industry basis to determine whether or not or to what extent, state antitrust and unfair competition laws are barred or restricted. We can help you decipher these doctrines and determine whether the antitrust claims that you are defending or thinking of bringing are barred by these doctrines.
