Loose lips have been sinking ships recently, and Apple this week filed yet another lawsuit regarding a product leak. This time, three developers have been charged with posting a pre-release version of the upcoming Tiger operating system to the internet via the BitTorrent file-sharing network.

The lawsuit was filed Monday and seeks an injunction against further leakages, as well as an unspecified amount of monetary damages. The developer release was first posted in late October, with further postings continuing through this month. Over 2,500 copies of the unreleased Tiger OS are thought to have been downloaded.
