<A HREF=showrelatednews.asp?AdditionalURLs=http%3A%2F%2Fwww%2Eaol%2E&NotArticleID=14302>AOL Time Warner</A> have won a US patent for <A HREF=showrelatednews.asp?LinkedKeywords=Instant+Messaging&NotArticleID=14302>instant messaging</A> technology, opening up a potentially vast revenue source.
Rivalling text-messaging as one of the most popular new media communication tools, instant messaging was developed in the mid 90's by Israeli company <A HREF=showrelatednews.asp?AdditionalURLs=http%3A%2F%2Fwww%2Eicq%2E&NotArticleID=14302>Mirabilis</A>, which was bought by AOL in 1998.
Mirabilis' ICQ was the first technology to allow this quick and convenient form of direct communication, that is now used by approximately 320m AOL users alone, carrying some 2.1bn messages daily.
The move is an important <A HREF=showrelatednews.asp?LinkedKeywords=Legal&NotArticleID=14302>legal</A> step in AOL's long-running battle with rivals <A HREF=showrelatednews.asp?AdditionalURLs=http%3A%2F%2Fwww%2Emicrosoft%2E&NotArticleID=14302>Microsoft</A> and Yahoo- both of whom have their own forms of instant messaging. The real question is whether AOL will decide to enforce the patent, which it has chosen not to do in the past with its' 'cookies' and SSL <A HREF=showrelatednews.asp?LinkedKeywords=Patents&NotArticleID=14302>patents</A> (among others).
Despite AOL's protective attitude toward this piece of technology, that has led some to speculate that they might enforce this patent, a London spokesperson for AOL told Reuters that "There are no plans to do anything with the patent at this time."
Recently, both AOL and Microsoft have begun to work on secure instant messaging applications for use by corporate clients such as Reuters.
