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.
