TIMELINE: ISP SUBPOENAS AND ANONYMITY
Any “copyright troll” bittorrent-based copyright infringement lawsuit really revolves around the subpoena which moves from the court to the accused John Doe Defendants. Tracking a subpoena can help an accused defendant understand the timelines of when they can fight, when they can settle, when they can ignore, and whether they are anonymous or not at each step.
A Subpoena is first introduced to the court for approval.
A subpoena is first introduced to the court when the plaintiff attorney files the lawsuit and asks the court for permission to obtain the identities of the various internet users accused of downloading the copyright holder’s movie or copyrighted work.
The Subpoena, once approved by the court, is sent to the ISP.
The federal judge approves the subpoena (usually by rubber stamp), and the subpoenas are then sent to the “abuse” department of the various ISPs (e.g., AT&T U-verse, COX Communications, Comcast, etc.). These ISPs in receipt of the subpoena are ordered to hand over the accused subscriber’s information to the plaintiff attorney. They send a notice to the account holder that a subpoena has been received, and that they are under a duty to comply with the subpoena by a certain date unless the account holder files a Motion to Quash the subpoena before the arbitrary deadline they set (usually the deadline is 30 days from the notice sent to the subscriber).
The ISP forwards the Subpoena to the accused account holder giving him a chance to file an objection with the court.
You (the account holder) receive the notice containing the subpoena, and you learn that you are implicated as a “John Doe” (an unnamed defendant) in the Copyright Holder Corporate Entity v. Does lawsuit. Here, you learn that you can supposedly stop the ISP from handing out your information to the plaintiff attorney by filing an objection with the court, a.k.a. a “Motion to Quash.” At this point, you are still anonymous.
The ISP complies with the Subpoena and hands over your contact information to the plaintiff attorney.
Assuming you do not file the Motion to Quash (there are many articles on this website explaining why you might not do so), the 30-day deadline set by your ISP will lapse, and your ISP will comply with the subpoena. They turn over your information to the PLAINTIFF ATTORNEY (but not to the court or anyone else). You are still anonymous.

The exact moment your anonymity expires.
At this point, the life of the subpoena is over, as it has served its purpose and the plaintiff attorney is in receipt of your contact information (and whatever other information your ISP was forced to hand over to it). At this point, you are a “John Doe” defendant in the lawsuit, and only your plaintiff attorney knows your real identity. YOU ARE STILL ANONYMOUS at this point (as to the court and the world, as the plaintiff attorney is not going to share your information unless he decides to name and serve you as a defendant in the lawsuit).
Your anonymity expires once the plaintiff attorney realizes that he or she cannot get a settlement from you, and based on their evidence that you are the downloader of their client’s copyrighted movie, they file an amended complaint with the court with your name as a defendant, and they serve you with a copy of the complaint. At this point, you have been “named and served,” and you are no longer anonymous. At this point, you need to decide whether it makes more sense to stand and defend against the claims against you (consider the attorney fees issue), or to negotiate a settlement and amicably step away from the lawsuit.
NOTE: If you choose to fight, be aware of Prof. Matthew Sag’s paper entitled “Defense Against the Dark Arts of Copyright Trolling,” and the considerations surrounding using what are otherwise “valid” defenses to copyright infringement which likely DO apply to your case.

Until when an I anonymous?

It depends. Before your ISP hands your contact information to the plaintiff attorney in response to an ISP subpoena, you are anonymous.
If you do not file a motion to quash and your ISP provides your contact information to the plaintiff attorney, you are no longer anonymous because the plaintiff attorney knows who you are.
However, the entire time you are a John Doe Defendant, you are anonymous as far as the world is concerned until you are named and served as a defendant. Until then, nobody knows you are involved in the lawsuit, and nobody other than the plaintiff attorney knows you are accused of the unlawful conduct.
I don’t need to file a lawsuit and ask the court to get a subpoena:
18 U.S.C. 512(h)
A copyright owner or a person authorized to act on the owner’s behalf may request the clerk of any United States district court to issue a subpoena to a service provider for identification of an alleged infringer in accordance with this subsection.
