Litigation involving the Wikimedia Foundation

The Wikimedia Foundation has been involved in several lawsuits. Some of them have gone in favor of the Foundation, others have gone against it.

This listing is not meant to be exhaustive, and only includes notable cases.

Outcomes in favor of the plaintiffs

In May 2011, Louis Bacon obtained a court order against the Wikimedia Foundation to compel it to reveal the identity of the editors who defamed him on Wikipedia. However, the order was obtained in the UK, and is therefore unenforceable in the United States.[1][2]

In January 2019, a court in Germany ruled against the Wikimedia Foundation, prompting it to remove part of the history and the allegedly defamatory content about a professor. The Wikipedia article's content was ruled defamatory because the link supporting its claims was no longer active, a phenomenon known as "link rot."[3]

Outcomes in favor of the Wikimedia Foundation

Barbara Bauer, a literary agent, sued Wikimedia Foundation for defamation.[4][5] She claimed that a Wikipedia entry branded her the “dumbest” literary agent.[5] The case was dismissed because of the Communications Decency Act.[6]

Professional golfer Fuzzy Zoeller, who also felt he was defamed on Wikipedia, did not sue Wikipedia because he was told that his suit would not prevail in light of the Communications Decency Act.[7] He then sued the Miami firm from whose computers the edits were made, but later dropped the case.[8]

In 2007, three French nationals sued the Wikimedia Foundation when an article on Wikipedia described them as gay activists.[9][10] A French court dismissed the defamation and privacy case, ruling that the Foundation was not legally responsible for information in Wikipedia articles.[10] The judge ruled that a 2004 French law limited the Foundation's liability, and found that the content had already been removed.[9][10] He found that the Foundation was not legally required to check the information on Wikipedia, and that "Web site hosts cannot be liable under civil law because of information stored on them if they do not in fact know of their illicit nature."[10] He did not rule whether the information was defamatory.[9][10]

Sylvia Scott Gibson, author of Latawnya, the Naughty Horse, Learns to Say "No" to Drugs, sued Wikipedia for describing her book.[11] Her suit was dismissed.[12]

Other alleged defamation

John Seigenthaler, an American writer and journalist, contacted Wikipedia in 2005 after his article was edited to incorrectly state that he had been thought for a brief time to be involved in the assassinations of John F. Kennedy and Bobby Kennedy. The content was present in the article for four months.[5][13] Seigenthaler called Wikipedia a "flawed and irresponsible research tool," and criticized the protection the Communications Decency Act provided to Wikipedia.[5]

The representative for the American Academy of Financial Management, George Mentz, suggested that either phony or incompetent Wikipedia editors were creating legal problems for Wikimedia in May 2013, because of alleged intentional false claims that had been published on Wikipedia.[14]

In 2014, Yank Barry filed a defamation lawsuit against four Wikipedia editors,[15][16] and then withdrew it after about a month.[17]

DMCA takedown notices

Texas Instruments sent a DMCA takedown notice to the Wikimedia Foundation because certain cryptographic keys were made public in the Texas Instruments signing key controversy article. A Wikipedia editor later filed a counter-notice, Texas Instruments did not reply in 10–14 business days as required by the DMCA, and the keys were restored to the article.[citation needed]

Two other articles also came under the purview of Wikipedia's office actions[clarification needed] because of the DMCA: Damon Dash and Conventional PCI.

FBI seal controversy

In July 2010, the FBI sent a letter to the Wikimedia Foundation demanding that it cease and desist from using its seal on Wikipedia.[18] The FBI claimed that such practice was illegal and threatened to sue. In reply, Wikimedia counsel Michael Godwin sent a letter to the FBI claiming that Wikipedia was not in the wrong when it displayed the FBI seal on its website.[19] He defended Wikipedia's actions and also refused to remove the seal.[20]

NSA lawsuit

In March 2015, the Wikimedia Foundation, along with other groups, sued the National Security Agency over its upstream mass surveillance program.[21]

Wikimedia Foundation, Inc. v. WordLogic Corporation et al

Wikimedia Foundation, Inc. v. WordLogic Corporation et al was a lawsuit involving the Wikimedia Foundation as plaintiff and the companies WordLogic Corporation and 602531 British Columbia, Ltd. as defendants over a patent dispute.[22] WordLogic claims that the Wikimedia Foundation and the MediaWiki free software infringes on at least Claim 19 of the U.S. Patent 7,681,124.[23] Wikimedia denies those claims and has moved under 28 U.S.C. §§ 22012202 for a declaratory judgment against the WordLogic entities requesting a declaration from the Court that a number of patents property of defendants are invalid, and that Wikimedia Foundation does not infringe those patents "directly or indirectly, either literally or under the doctrine of equivalents" as provided by the Title 35 of the United States Code. The case was filed on March 11, 2020 before the United States District Court for the Northern District of California.[24] On July 18, 2020 Wikimedia Foundation, Inc. moved to dismiss with prejudice its own complaint.[25]
