following a November 2007 announcement that Microsoft had "licensed the technologies from Eolas", in April 2008, Microsoft released an update which removed the click-to-activate functionality, reverting the software to its original design. In June 2006, Opera Software released version 9 of its Opera browser for Windows and other operating systems, with modifications similar to Microsoft's. Doyle has stated that Eolas will offer royalty-free licenses to non-commercial entities. A statement on Eolas' web site clarifies the company's policy with regard to such licenses. , Mozilla Foundation, which develops the open-source Mozilla Firefox browser, has not announced that it has requested any license to the Eolas patents; the last of these patents expired prior to the end of 2017. Proposed Workarounds Before some claims in the company's patents were invalidated in 2012, one proposed workaround was to dynamically create the HTML element containing the plug-in using JavaScript, rather than embedding it on the page. In this situation, Internet Explorer did not ask the user for an "activation" click because of the infringers' argument that the patent did not cover embedded scripting. Opera users could use User JavaScript functionality in the browser to attempt to work around this issue in a similar way with locally modified JavaScript.
