LexisNexis Group is a corporation providing computer-assisted legal research as well as business research and risk management services. During the 1970s, LexisNexis pioneered the electronic accessibility of legal and journalistic documents. As of 2006, the company has the world's largest electronic database for legal and public-records related information.〔 ==History== Currently a division of RELX Group (formerly Reed Elsevier), LexisNexis was first a product of the Mead Data Central company.〔 The Anglo-Dutch publishing company Reed Elsevier has owned LexisNexis and its predecessor company since 1994. At its inception in 1970, the database was named LEXIS by Mead Data Central (MDC), a subsidiary of the Mead Corporation. It was a continuation of an experiment organized by the Ohio State Bar in 1967. On April 2, 1973, LEXIS launched publicly, offering full-text search in all Ohio and New York cases. In 1980, LEXIS completed its hand-keyed electronic archive of all U.S. federal and state cases. The NEXIS service, added that same year, gave journalists a searchable database of news articles.〔Regarding the capital letters in the name; it was then standard to capitalize the names of online services.〕 LexisNexis' world headquarters is located in Dayton, Ohio, United States.〔 In 1989, MDC acquired the Michie Company, a legal publisher, from Macmillan. When Toyota launched the Lexus line of luxury vehicles in 1987, Mead Data Central sued for trademark infringement on the grounds that consumers of upscale products (such as lawyers) would confuse "Lexus" with "Lexis". A market research survey asked consumers to identify the spoken word "Lexis". Survey results showed that a nominal number of people thought of the computerized legal search system; a similarly small number thought of Toyota's luxury car division.〔A far greater number, although by no means a majority, thought of a television character; most thought of nothing at all.〕 A judge ruled against Toyota, and the company appealed the decision.〔''Mead Data Cent. v. Toyota Motor Sales, U.S.A.'' 702 F.Supp. 1031 (1988)〕 Mead lost on appeal in 1989 when the Court of Appeals for the 2nd Circuit held that there was little chance of consumer confusion.〔''(Mead Data Cent., Inc. v. Toyota Motor Sales )'' 875 F.2d 1026 (1989)〕 Today, the two companies have an amicable business relationship, and in 2002 implemented a joint promotion called "Win a Lexus on Lexis!" In December 1994, Mead sold the LexisNexis system to Reed Elsevier for $1.5 billion. The U.S. state of Illinois subsequently audited Mead's income tax returns and charged Mead an additional $4 million in income tax and penalties for the sale of LexisNexis; Mead paid the tax under protest, then sued for a refund in an Illinois state court. On April 15, 2008, the U.S. Supreme Court agreed with Mead that the Illinois courts had incorrectly applied the Court's precedents on whether Illinois could constitutionally apply its income tax to Mead, an out-of-state, Ohio-based corporation.〔''MeadWestvaco Corp. v. Illinois Dep't. of Revenue'', 553 U.S. 16 (2008).〕 The Court reversed and remanded so that the lower courts could apply the correct test and determine whether Mead and Lexis were a "unitary" business. In 2000, LexisNexis purchased RiskWise, a St. Cloud, Minnesota company. In 2002 it acquired a Canadian research database company, Quicklaw. In 2004, Reed Elsevier Group, parent company of LexisNexis, purchased Seisint, Inc, of Boca Raton, Florida. Seisint housed and operated the Multistate Anti-Terrorism Information Exchange (MATRIX). On March 9, 2005 LexisNexis announced the possible theft of personal information of some Seisint users. It was originally estimated that 32,000 users were affected, but that number greatly increased to over 310,000. Affected persons were provided with free fraud insurance and credit bureau reports for a year. However, no reports of identity theft or fraud were discovered to have stemmed from the security breach. In February 2008, Reed Elsevier purchased data aggregator ChoicePoint (previous NYSE ticker symbol CPS) in a cash deal for US$3.6 billion. The company was rebranded as LexisNexis Risk Solutions.〔(【引用サイトリンク】title=LexisNexis Risk Solutions )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「LexisNexis」の詳細全文を読む スポンサード リンク
