Elsevier's "peer review" claims are commercial advertising, but not shown false or connected to P's harm

Global Plasma Solutions, Inc. v. Elsevier LTD, 2026 WL 3168613, No. 3:22-CV-00034-KDB-WCM (W.D.N.C. Oct. 22, 2026)

Wow, a case where Elsevier is entirely in the right. GPS alleged that its air purifier business was greatly harmed by a defamatory article published in Building and Environment, a scientific journal owned by Elsevier, during the 2020 pandemic, and also that Elsevier’s advertisement of BAE’s articles as “peer reviewed” violated the Lanham Act.

The court first found that GPS was a limited purpose public figure with respect to the safety and efficacy of its bipolar ionization technology and couldn’t establish by clear and convincing evidence that Elsevier published the article with “actual malice.” Nor could a reasonable jury find that consumers were misled by the truthful statements that the article was “peer reviewed” or that an Elsevier ad was a proximate cause of GPS’s claimed diminution in its corporate value, kicking out the Lanham Act claim.

GPS alleged that its NPBI technology generates negative and positive ions which reduce airborne viruses and bacteria, remove particles from the air via agglomeration, and help to remove odors via particle removal.

“Obviously, the issue of clean air is one of major public importance.” “There has long been public interest and scientific debate over the safety and effectiveness of the various technologies that claim to improve the quality of the air indoors, including ionization technology.”

In 2018, researchers at the New York State Department of Health published an article in the ASHRAE Journal that explained air cleaners labeled as “bipolar ionizing” can generate reactive oxygen species (“ROS”) that react with volatile organic compounds (“VOCs”) to create harmful byproducts such as ozone, formaldehyde, and acetone. GPS emailed the article’s lead author attaching a GPS-authored paper, attempting to persuade him that “GPS’s technology is very different than all other technologies.” GPS’s founder and inventor of its technology also published a public response on behalf of GPS in the ASHRAE Journal, to which the NYDOH researchers published a reply explaining that “GPS manufactures ion generation devices, which must form ROS to perform ‘air purification’: ROS react with volatile organic chemicals, forming ultra-fine particles and aldehydes, as was shown in our study.” (ASHRAE is an important body in the field.)

GPS then commissioned more than 20 tests to position its devices as effective against COVID-19 and other pathogens, touting them in public statements. Scrutiny of GPS’s devices followed, including articles contesting their safety and efficacy.

BAE’s audience is civil engineers, environmentalists, planners, architects and designers. BAE published an article titled “Evaluating a commercially available in duct bipolar ionization device for pollutant removal and potential byproduct formation,” which studied a GPS device. It noted the “unprecedented level of interest and investment in indoor air cleaning technologies,” which are often “not evaluated by any federal agency or industry standards organizations for their efficacy or their potential for unintended consequences, including the generation of chemical byproducts.” The Article then summarized the debate about bipolar ionizer devices, and identified its topic as the “effectiveness or potential for byproduct formation of bipolar ionization devices used in realistic settings.” Its two reported experiments found an increase in some hydrocarbons (e.g., xylenes) but an increase in others, most prominently oxygenated VOCs; it called for further investigation.

BAE used peer review based on internal guidelines. Given that invited reviewers will often decline the invitation to review. Therefore, an editor may make a decision on whether to accept the paper for publication based on a single review report “if the review is comprehensive and thorough,” although “the use of [a] single reviewer should be rare” and “two review reports may not be sufficient” if one of the reviewers does not “deliver a quality report.” The publication decision is ultimately left to the editor, who is instructed to “look at review quality and credentials to make your own judgment.” Elsevier testified that it is the individual “editor’s choice as to which articles they accept” consistent with “editorial independence,” because editors, not Elsevier or its employees, are the subject matter “expert[s]” best positioned to judge scholarly works in their respective fields.

The initial screener here had published papers on air cleaning, which included measuring gases and particles in test rooms and real environments; he sent it to three reviewers, none of whom were alleged to have been unqualified, for comments and ratings on numerical scales. The reviews were mixed (“Major Revision,” “Reject” (without specific comments; the editor concluded that Reviewer 2 hadn’t really tried), and “Minor Revision,” with overall ratings that were generally qualified for publication). After revision, Reviewer 3 switched to “Accept,” while Reviewer 1 stayed with “Major Revision” but scored the article more favorably numerically. After another round of revisions, the editor accepted the article.

Elsevier regularly advertises its journals as “peer reviewed” and touts a “rigorous editorial and peer review” process.

GPS alleged that the Article’s statements about how its bipolar ionization technology performed during testing were false and “devastated” their business because “many of GPS’s customers paused, canceled, or stopped orders” as a result. They made no claim against the authors, despite attacking their alleged biases; there was no evidence that Elsevier was aware of these biases.

Defamation: “To encourage the broad and searching debates necessary for scientific progress, scientific conclusions and opinions cannot be the subject of defamation liability, in the absence of fabricated or dishonestly presented data or methodology.” But the court didn’t have to resolve the “close” question of whether the article was scientific opinion, given the absence of evidence of actual malice.

GPS didn’t dispute that the testing was conducted as described or argue that the data were fake. Instead, it argued that the key data presented—the different levels of VOCs after bipolar ionization—was an (accurate but undisclosed) average of two testing results rather than the actual results; certain Q values (which GPS argued indicated whether the VOCs were properly identified) were allegedly omitted or were too low to be valid; “cause and effect” conclusions were impossible with only a single chamber test experiment; and the study lacked basic scientific competence because its experimental design, data collection, and analysis were deficient. But how the authors designed and carried out the study, including use of a single chamber test and how they identified VOCs, was disclosed in the article. “Readers have enough information to decide for themselves whether to believe or disbelieve the study’s results” based on the Q values.

The court (correctly, I think, given how humans understand language) rejected Elsevier’s argument that the authors “hedged” their conclusions with qualifying language such as saying that the data “appears” to show or “suggests” various conclusions and ultimately calling for further study. Viewing the article as a whole, its conclusions weren’t sufficiently tentative to grant summary judgment on that ground.

And the court found the use of averages to be the most substantial criticism. The “core conclusion” was that the levels of certain VOCs increased after the air was subjected to the bipolar ionization device, and, for at least some of the VOCs, the two samples were very different, with one sample reflecting a decrease after ionization and the other representing a substantial increase. The averages were neither “fabricated” nor “fraudulent.” But “the lack of a disclosure that an average was taken and the fact that the underlying data is not made available to the reader is concerning” and “may have affected the readers’ ability to fully assess the study’s findings.”

Rather than definitively resolving the issue, the court ruled on actual malice: the claim that the authors hid the issue further undercut actual malice “because there is no evidence that Elsevier was given access to or had any reason to know about the supposedly contradictory results (and of course any argument that Elsevier should have taken some notice from the Article itself would similarly apply to any reader).”

GPS was a limited-purpose public figure under the governing test: “whether (1) the plaintiff has access to channels of effective communication, (2) the plaintiff voluntarily assumed a role of special prominence in the controversy, (3) the plaintiff sought to influence the resolution of the controversy, (4) the controversy existed prior to the publication of the defamatory statements, and (5) the plaintiff retained public figure status at the time of the alleged defamation.” There was “an ongoing public controversy about the safety and efficacy of air cleaning technologies, specifically including bipolar ionization.” Nor was GPS a bystander or “involuntarily” thrust into the debate. “Instead, it sought to be an opinion leader supporting the technology, using its considerable resources and available channels of communication to challenge ASHRAE Journal articles, prepare a white paper, and commission testing on COVID-19 effectiveness (which it then touted in press releases).”

There was no evidence that Elsevier had actual knowledge of any falsity, and its publication process wasn’t reckless. It assigned the article to a qualified editor who selected three qualified and independent peer reviewers. Each reviewer (even Reviewer 2) gave the article a passing score and stated their belief at least once that the article “succeed[ed] by a small amount” with respect to the statement “the conclusions were supported by the data.” The editor determined that the authors had sufficiently revised the article or explained why they had not. “[N]othing in these undisputed facts suggests, much less establishes with the required level of certainty or high probability, that Elsevier acted with a reckless disregard of the falsity of the Article.”

GPS argued that Elsevier was reckless because it knew that the editor was too overworked to do his job properly. Nonetheless, the question was whether Elsevier acted, with respect to this particular article, “with a high degree of awareness of its probable falsity.”  

Elsevier may be too focused on its profitability at the expense of a more careful review of its published articles and its editors may be overworked, but there is no authority for the proposition that those allegations standing alone can support a finding of actual malice in the absence of particularized evidence showing that Elsevier entertained serious doubts about the veracity of the Article. Otherwise, every harried editor and commercially driven publisher (which the Court hazards to guess includes most all of them) would be at risk of a jury verdict of defamation for every scientific study in which undisclosed errors are later found. Such a result is the antithesis of “actual malice” and cannot be accepted without undermining the search for elusive scientific “truth.”

Lanham Act false advertising: Although Elsevier’s frequent marketing of its journals, including BAE, as “peer reviewed” was “commercial advertising,” that didn’t matter. There was no literal falsity.

GPS argued that the peer review didn’t meet the journal’s own internal standards, but that wasn’t the same thing as ads that promise compliance with a publicly recognized regulatory or statutory standard, such as “FDA approved.” “GPS cites to no such clear legal standard (or even a specific widely accepted public definition) with respect to the details of what constitutes a ‘peer review’; instead, it points to Elsevier’s publication protocols, which were indisputably private, not included in any advertisement and, in any event, flexible “guidelines” rather than rigid rules.” The court noted that, “[i]f liability is imposed on these claims for the failure to follow internal guidelines in the absence of evidence that otherwise satisfied the established legal standard, then publishers will in the future simply limit their peer review process to whatever bare minimum might be acceptable to avoid liability. This race to the bottom risks significantly degrading rather than promoting vigorous peer review, to the detriment of scientific research.”

There was likewise no material factual issue on misleadingness. Its corporate representative’s testimony that customers viewed peer-reviewed articles as “beyond reproach” and “gospel”; its expert’s testimony as to the meaning of “peer review” to scientists; and the testimony of three of Elsevier’s customers that it was important to them that the article was “peer reviewed” were insufficient in the absence of evidence that any BAE subscriber—the relevant audience—was misled.

Also, the question here wasn’t whether peer review was material/increased credibility. “[T]o satisfy its burden, GPS must establish that a substantial portion of individual subscribers had specific relevant beliefs as to how a peer review would be conducted (if in fact they had any view at all) and that the publication process for the Article materially varied from that understanding so that they were misled.” That evidence was lacking. “[H]ow many in the relevant audience believed that a peer review can involve approval by a single reviewer, had a view as to what should happen if there are two reviewers and they disagree, or would allow an editor to exercise his or her discretion to ignore a review that includes no justification for a recommendation not to publish?” A jury could only speculate.

Plus, there was no evidence of any causal connection between the harm for which GPS sought to recover and the challenged ads. There was no evidence that any GPS customer saw or heard about an Elsevier ad; they may simply have assumed the existence of peer review.
