To various lists: In a welcome move toward open software standards in OASIS, Sun Microsystems has covenanted not to enforce its patents against implementations of the Open Document Format for Office Applications (OpenDocument) specification. [See http://www.oasis-open.org/committees/office/ipr.php.] This is a good thing because it allows the development of free and open source implementations of office applications without fear of patent infringement claims by Sun. Most important, because this is from Sun, a company that plays an important leadership role in many standards organizations, this is an example for other OASIS member companies to follow. It proves once and for all that patent holders in OASIS working groups can find reasonable ways to allow their patents to be implemented for software standards without demanding royalties or imposing burdens of license execution and restrictions on sublicensing. I hope that other patent holders will do the same for the OASIS standards to which they contribute. If they follow this lead, we will no longer have the spectres of patent infringement lawsuits and RAND-type licensing for software applications that implement OASIS standards. Both open source and proprietary software can thrive in that environment. /Larry Rosen Lawrence Rosen Rosenlaw & Einschlag, technology law offices (www.rosenlaw.com) 3001 King Ranch Road, Ukiah, CA 95482 707-485-1242 * fax: 707-485-1243 Author of "Open Source Licensing: Software Freedom and Intellectual Property Law" (Prentice Hall 2004) [Available also at www.rosenlaw.com/oslbook.htm]
