Dr. Reese Richardson, a specialist in scientific research integrity, has been investigating a growing network of “paper mills” — clandestine organizations that profit by selling fraudulent authorship on scientific papers, intellectual property registrations, and other academic outputs. These operations exploit the pressure on researchers to publish swiftly, especially in regions where scientific publications heavily influence career progression, funding, and reputation.
Paper mills offer a shortcut by providing buyers with authorship on fabricated or manipulated research articles, often circumventing the traditional peer review process. Richardson, along with colleagues Anna Abalkina and Spencer Hong, analyzed more than 18,000 advertisements from seven paper mills operating across seven countries between 2020 and 2026. Their analysis, which has yet to undergo peer review, revealed median prices for authorship around $800, with some offers as low as $30. These ads circulate primarily on platforms such as Telegram, WhatsApp, Facebook, and various websites.
According to Richardson, the prevalence of paper mills has surged significantly in the past 15 years, with outputs doubling approximately every 18 months. Many of the fraudulent articles slip through journals that either lack rigorous editorial oversight or whose editors may be complicit. This widespread manipulation not only undermines scientific credibility but also threatens critical fields such as medical research, drug discovery, and clinical trials. For example, the now-defunct Hindawi journal brand retracted over 8,000 articles in 2023 alone, with an additional 3,000 retractions recorded by the end of 2024.
Beyond false authorship, some paper mills also offer fraudulent intellectual property services, including design registrations that can be misrepresented on academic curricula vitae. Richardson’s research identified at least 12 instances where paper mills in India marketed "Australian design patents" to local academics, charging between $65 and $100 to list multiple “owners” on individual registrations. The standard cost for such a design registration through IP Australia is approximately 200 Australian dollars (about $146 USD).
Among these registrations is an “AI based membrane bioreactor for treatment of wastewater” credited to six individuals affiliated with Indian research institutes. Efforts to contact those named have gone unanswered. A noted anomaly includes the listing of a “GS Collison” at a Sydney address corresponding to a major insurance firm’s office space, but no evidence links that name to any legitimate entity.
In one case, Dr. Nilesh Torwane, a postdoctoral researcher at the University of Queensland, was named on a design registration for a “Smart humanoid robot for industrial applications” without having contributed to the design. Torwane stated he agreed to be listed by others but has not used the registration to advance professionally or academically and is working with his university to remove his name.
IP Australia acknowledged the research but expressed no current evidence of systemic misuse within its registration system and stated it would consider the implications raised by Richardson’s findings.
Despite growing awareness, experts stress that paper mills remain elusive. Professor Adrian Barnett of Queensland University of Technology, who has collaborated with Richardson, described these operations as opaque entities that could range from small, informal setups to larger organizations. The rapid proliferation and commercial scale of paper mills pose ongoing challenges for the scientific community’s efforts to safeguard integrity. Richardson emphasized that current investigations have only begun to uncover the scope of these fraudulent networks, warning that there is still much more to explore.
