The coupling of Microsoft and Lawrence Lessig, an outspoken proponent of loosening restrictions on copyrights for digital content, may seem an unlikely one. But the software company and Lessig\u2019s Creative Commons organization will announce Wednesday that they\u2019ve teamed up to develop a tool that lets Microsoft Office users create Creative Commons licenses from within Microsoft Office documents.Creative Commons licenses allow an author of published material to decide how he or she wants to allow others to republish or reuse that work. The new copyright licensing tool will enable people creating documents in Office, PowerPoint or Excel to immediately attach a Creative Commons license to the document through an option in the applications\u2019 "File" command, said Tom Rubin, a Microsoft associate general counsel for intellectual property.The tool will be available Wednesday as a free download on both Microsoft\u2019s website and the Creative Commons site.Currently, copyright law "operates automatically to say the author reserves all rights to himself," said Lessig, a law professor at Stanford University and founder of its Center for Internet and Society. The objective behind a Creative Commons license is to "provide a simple way to say, \u2018Here is the freedom you have to make derivations [and changes] while I continue to have some rights to myself,\u2019 " he said. This kind of freedom is especially important for material published on the Internet, which, since it is in such a public domain already, may not necessarily need the same kind of restriction as a book or journal article, Lessig said.Though Rubin said Microsoft has teamed up before with Creative Commons on some smaller projects, the pairing may seem surprising to many, as there is little love lost between Microsoft and Lessig. The company\u2019s claim that Lessig was biased against it caused the attorney to lose his job as an adviser, or "special master," to Judge Thomas Penfield Jackson during the Department of Justice\u2019s antitrust case against the vendor. Since then, Lessig has been outspoken in his view that Microsoft should have faced a harsher sentence in that case."It\u2019s an interesting set of bedfellows," noted Rob Enderle, analyst with The Enderle Group in San Jose, Calif. "Lawrence Lessig hasn\u2019t exactly been a great Microsoft fan."Still, the partnership has positive implications for both sides, he said. Lessig wins a significant partner in his push for removing some of the restrictions from copyrights, and Microsoft offers a useful tool that will make current and potential Office users happy, Enderle said.Lessig founded Creative Commons in December 2002, and today there are about 140 million published works\u2014which include audio and video files, as well as documents and other printed materials\u2014that use a Creative Commons license, he said.-Elizabeth Montalbano, IDG News Service (San Francisco Bureau)This article is posted on our Microsoft Informer page.\u00a0For more news on the Redmond, Wash.-based powerhouse, keep checking in.Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
