Mass copyright infringement lawsuits filed against anonymous BitTorrent users—commonly called John Doe defendants—have flooded federal courts across the United States. The case Purzel Video GMBH v. Does, filed in the Northern District of Illinois, is one example of this litigation pattern and illustrates the legal landscape that defendants in these cases face. If you have been targeted in this or a similar lawsuit, understanding the structure of these cases and your legal options is essential.
Attorney Paul Lesko of Simmons Browder Gianaris Angelides & Barnerd filed this copyright infringement lawsuit against 84 John Doe defendants in the Northern District of Illinois. The complaint alleged that each defendant participated in downloading and distributing the adult film Cream Pie Young Girls 1, produced by Purzel Video GMBH, through a BitTorrent peer-to-peer file sharing network. Each defendant was identified only by an IP address at the time of filing.
This type of lawsuit—naming dozens or hundreds of anonymous defendants identified only by IP address—became common between 2010 and 2015. Plaintiffs in these cases used them primarily as a settlement extraction mechanism: file a lawsuit, subpoena the ISPs to unmask the subscribers behind the IP addresses, send settlement demands, and rely on the embarrassment of being accused of downloading adult content to pressure defendants into paying even when the underlying claims might be weak.
BitTorrent is a peer-to-peer file transfer protocol that allows users to download files in small pieces from multiple sources simultaneously. A user who downloads a file through BitTorrent simultaneously distributes pieces of that file to other users—a process called seeding. Copyright holders argue that both downloading and seeding constitute infringement of their exclusive distribution and reproduction rights under 17 U.S.C. § 106.
Copyright trolls (a term used to describe plaintiffs who file these mass cases primarily for settlement purposes rather than to vindicate legitimate copyright interests) monitor BitTorrent networks using automated tools that log the IP addresses of users participating in swarms for specific files. Those IP address logs form the core of their evidence. They then file suit against all logged IP addresses as a group, identifying each by the IP address observed during monitoring.
Federal courts, including those in the Northern District of Illinois, have grown increasingly skeptical of mass John Doe BitTorrent cases. Courts began questioning whether IP addresses gathered over extended time periods from geographically dispersed users satisfied the joinder requirements of Federal Rule of Civil Procedure 20, which requires that all defendants have participated in the same transaction or series of transactions and that common questions of law or fact arise. Many judges severed and dismissed all but the first named defendant after determining that individual transactions on a BitTorrent network do not constitute a single transaction or occurrence.
Courts also scrutinized the plaintiffs’ true purpose in filing these cases. When it became clear that many plaintiffs had no intention of actually litigating the merits and were simply using the court’s subpoena power to obtain subscriber information for settlement campaigns, judges began refusing to grant expedited discovery or dismissing cases outright.
Being named as a John Doe defendant in a BitTorrent copyright case does not mean you are guilty of infringement. A number of defenses are available:
Courts have consistently recognized that an IP address does not identify a person—it identifies an Internet connection. Multiple individuals may share a single connection. Identifying the account holder does not establish that the account holder was the one who downloaded the file. This is a fundamental weakness in IP-address-based copyright infringement claims.
The IP logging software used by copyright monitoring firms is not infallible. Errors in IP assignment, clock synchronization issues, and geolocation mismatches have caused false positives. An experienced attorney can challenge the reliability of the IP evidence through discovery and, if necessary, expert testimony.
Copyright infringement claims must be filed within three years of the date the plaintiff knew or should have known of the infringement. 17 U.S.C. § 507(b). If the alleged infringement falls outside this window, the claim is time-barred.
If you are named in a multi-defendant case, your attorney can move to sever your case from the other defendants. Severance often causes plaintiffs to abandon individual cases because the cost of litigating each case separately exceeds the expected settlement value.

Acting promptly matters: deadlines in federal litigation move quickly, and the window to respond to ISP subpoenas is limited.
Purzel Video and similar copyright trolling enterprises pursued a business model that depended on the economics of mass litigation: file a single complaint against hundreds or thousands of anonymous John Doe defendants identified only by IP address, issue subpoenas to ISPs en masse, collect settlements from defendants who preferred to pay rather than be named publicly, and dismiss those who did not respond. Courts eventually imposed significant procedural constraints on this model, and the majority of mass BitTorrent cases were dismissed before any defendant was individually served.
The most significant judicial pushback came from courts in the Northern District of Illinois, the Southern District of New York, and the District of Columbia. Judges in these districts denied joinder of unrelated defendants — holding that the mere fact that multiple defendants allegedly downloaded the same file via BitTorrent was insufficient to constitute a “same transaction or occurrence” under Fed. R. Civ. P. 20(a). Without joinder, the filing fee multiplied across hundreds of individual cases, collapsing the economic model.
Even where subpoenas were issued and account holders were identified, copyright trolls faced the problem that account holders are not necessarily infringers. Courts in several circuits held that an ISP subscriber is not the same as the person who downloaded the file — a principle that forced copyright trolls to either conduct additional investigation before naming defendants or face dismissal for insufficient pleading.
In cases where copyright trolls pursued defendants who ultimately prevailed, courts have awarded attorney’s fees under 17 U.S.C. § 505. In Kirtsaeng v. John Wiley & Sons, Inc., 579 U.S. 197 (2016), the Supreme Court clarified that courts should give “substantial weight” to the reasonableness of the losing party’s litigating position when awarding fees, and that frivolous or objectively unreasonable positions weigh strongly in favor of a fee award.
Fed. R. Civ. P. 11 sanctions have been imposed in cases where copyright trolls made representations about IP address identification technology that turned out to be scientifically unfounded, or where plaintiffs pursued claims against individuals who could not plausibly have been the infringer — including deceased account holders, elderly individuals with no internet access, and businesses whose IP addresses were publicly accessible.
For individuals who receive notices related to Purzel Video or similar entities, consulting a BitTorrent defense attorney promptly provides the best opportunity to assess whether a motion to quash the ISP subpoena is viable, what settlement terms might be available, and whether, if a case is actually filed, counterclaims or fee motions could create sufficient leverage to achieve a dismissal with prejudice.
