GPS Pushes Back: New Filing Defends Company and NPBI Technology Against False and Defamatory Study

CHARLOTTE, NC- (BUSINESS WIRE) – January 26, 2022 Global Plasma Solutions (“GPS”) filed a civil complaint for defamation and unfair and fraudulent commercial practices in the United States District Court of the Western District of North Carolina against the Dutch publishing company Elsevier for publishing and distributing false and misleading study using bipolar ionization technology GPS Needlepoint (“NPBI ™”). The note can be found here. GPS filed a lawsuit after receiving emails and dismissal of the lead author of the study, which revealed the full distortion and erroneous nature of the study.

The lawsuit contains the following factual information: in March 2021, Elsevier published a study entitled “Evaluation of a commercially available bipolar ionization device for the removal of contaminants and the formation of potential by-products (“Study”) in the journal Building and environment. The study, led by Illinois Institute of Technology professor Brent Stevens, was conducted with a predetermined result that GPS technology was ineffective and increased the number of some connections. The emails attached to the complaint show that the authors ignored conflicting data and distorted the results. The lead author of the study admitted under oath in testimony taken at another trial that the basic data reported in the study were false and contradicted the conclusions reached by the authors. The study was used to make false statements and incorrect conclusions about GPS technology. The lead author of the article also admitted under oath in early January 2022 that there were no experimental controls to test the ionizer in the on and off conditions in the reported field study. The emails attached to the complaint indicate that Stevens insisted on drawing media attention to his predetermined findings long before the test was completed.

Also, as set out in the 32-page complaint:

  • Evidence that NPBI GPS technology is working as advertised has been closed

  • Test data were selected cherries, ignoring conflicting results.

  • The authors did not repeat any of the experiments in the study. Experimental replication is an important step in the scientific process to ensure the reliability of data, analysis and results.

  • The authors were unable to install and use the GPS device in the manner recommended by the manufacturer, which spoiled all their results and made it virtually impossible to evaluate the data in any significant form.

  • Elsevier’s alleged peer review process was fictitious because it found no obvious flaws – in equipment, procedures and reporting. Each of these issues had to be found in the Elsevier peer review process before the article was published.

The article was used by GPS competitors to help create what they called a “bipolar response” to undermine GPS technology. Despite the evidence presented, Elsevier has not yet withdrawn the study.

Not surprisingly, Elsevier recently published Stevens ’second study, apparently trying to correct the errors of the first, erroneous study. GPS knew about this study even before its publication because GPS received emails between Stevens and Marwa Zaatari (a paid advisor to a GPS competitor) in which Zaatari arranges funding for a second study and helps manage testing. Knowing that the first study was erroneous and suppressed data, the authors of the second study departed from the conclusion that ionization increases the number of certain compounds, and instead tried to focus on particle reduction. However, the results are weak and, in fact, show the effectiveness of GPS technology, despite erroneous testing. Even in the second study, the authors hide their relationship with Zaatari, a direct competitor to GPS that sells filtering, and which is also an advisor to enVerid, which is also a competitor to GPS when they state, “they have no known competing financial interests or personal relationships that could affect the work reported in this article. ” GPS has many emails where Zaatari manages testing, and in one email Stevens notes his excitement that GPS competitors support it because it worksMost likely, it will help their industry. ”The second study is as biased as the first, but it is also an attempt by the authors to distance themselves from the obvious lies of the first study.
