Five pages delivered through a fax machine could cost a Sunrise, Fla., security company at least $2,500 plus attorney fees.

The recipient of the fax, Fort Lauderdale, Fla., architect William Leander Osborn, claimed the faxes from TEM Systems were unwanted. Under the 1991 Federal Telephone Consumer Protection Act, plaintiffs can bring suit in state court against anyone who sends them junk faxes, with damages of $500 per fax.
