Microsoft Details Changes to Internet Explorer in Wake of Eolas Suit, Mozilla Foundation Issues Statement

Tuesday October 7th, 2003

In August, Microsoft lost a patent infringement lawsuit filed by Eolas Technologies Inc., a spinoff of the University of California. The jury in the case decided that Microsoft's support for ActiveX controls, plug-ins and Java applets in its Internet Explorer browser infringes on United States Patent 5,838,906, owned by the University of California and licensed to Eolas in 1994. Microsoft was ordered to pay $521 million to Eolas and the University and also change the way Internet Explorer works. The software giant is appealing.

In the wake of the ruling, the World Wide Web Consortium held an ad-hoc meeting on the patent and later set up a Patent Advisory Group to investigate the issue.

Yesterday, Microsoft published some documents outlining the changes it will make to Internet Explorer to stop the program from infringing on the patent. These changes — which essentially amount to forcing the user to press an OK button before loading each ActiveX control — are accompanied by some steps that Web developers can take to allow their controls to continue working normally. These include providing any data required by controls inline (the patent only covers plug-in—like technologies that access external data) or creating controls using a script. Apple has supplied similar guidelines for avoiding the changes when embedding QuickTime movies, Macromedia has some advice for sites that use Flash, Shockwave or Authorware and RealNetworks is providing information for those who embed RealMedia presentations in their pages.

The Mozilla Foundation also issued a statement on the Eolas patent yesterday. Noting that the "matter highlights the degree to which web browser software is critical to the user experience of the web," Mitchell Baker assures Web developers that the changes proposed by Microsoft and others should be backwards-compatible with all current and future Mozilla browsers. To the best of our knowledge, Mozilla's plug-in implementation will not have to be changed as the ruling only applies to Microsoft. It is not yet known whether Eolas plans to take action against the Mozilla Foundation.

Thanks to everyone who has sent us information about this issue over the last few weeks.


#7 Saving the Browser

Some months back I became aware of the patent US 5,838,906 and the Eolas lawsuit against Microsoft, and followed a bit of conversation on the Net related to it. As many, I believed the issue would quickly go away because of ample prior art. Regrettably, this seems not to be the case.

It now seems that perhaps the browser itself and the browsing experience may have to be nontrivially modified as a result of the judgment. Although a bit late, if some of us perhaps dust off our old code, is there a chance that we could still save the browser through demonstration of clear prior art?

For my own interest, and for the record, I recently spent a little time pursuing my intuition that Lotus Notes R3 might be viable prior art relative to the patent in question. I am not an attorney, and I am surely not well versed in the nuances of the case, but it seems to me after initial investigation that there is indeed quite a bit of relevance.
