Microsoft Corp. on Wednesday said that is looking for ways to work more closely with developers of the Open Office open source project, while at the same time, apparently reserving the right to sue them, according to a legal agreement between Microsoft and Open Office's major sponsor, Sun Microsystems Inc., made public this week.
The agreement in question was signed in April of this year as part of Sun and Microsoft's landmark multibillion dollar settlement. It was released as part of Sun's annual U.S. Securities and Exchange Commission filings Monday.
The April agreement says that Microsoft can seek damages from Open Office users or distributors for any copy of Open Office installed after April 1, 2004. However, users of Sun's commercial distribution of Open Office, called StarOffice are protected from legal liabilities under the agreement, said Russ Castronovo, a spokesman for Sun.
Open Office includes a word processor, spreadsheet and presentation software based on technology Sun acquired in its 1999 purchase of Germany's Star Division Corp. Sun released the code under an open-source license in 2000.
While the agreement effectively safeguards a large group of Open Office users from Microsoft, it leaves new users vulnerable to potential legal action, said Richard Donovan, head of the antitrust practice at Kelley Drye and Warren LLP in New York City, who has followed the agreement. "From now on, you're on notice that if you're still putting Open Office out there, Microsoft is reserving the right to go after you," he said.
The fact that Sun has granted Microsoft the right to seek damages for Open Office after the April 1 date may indicate a weakening in Sun's support for the open source project, Donovan said. Agreeing to the clause would "only make sense if Sun had decided as a corporate strategy that they did not intend to pursue Open Office very vigorously afterwards," he said.
Sun's Castronovo disagreed with Donovan's assessment, saying that Sun's support for Open Office was "as strong as ever" and adding that Microsoft has always had the right to sue Open Office users. "That existed before, so nothing changed in that respect, he said. "Open source software is typically provided without warranty and liability coverage. Open Office is no different."
Open Office developers were somewhat confused by the "legalese" language in the clause, said Louis Suárez-Potts, a senior community development manager with CollabNet Inc., who works on the Open Office project. But Sun's level of support for the project has not changed since the April announcement, he said. "I don't see this special chumminess (between Sun and Microsoft) as affecting our work," he said.
But one open source advocate was troubled by the clause.
"It's ominous, because it means that Microsoft is holding open their right to sue end users of Open Office for patent infringement. And Sun is protecting itself by exempting StarOffice from exposure," said Pamela Jones, editor of the Groklaw.net Web site, which covers legal issues relating to Linux and open source software.
"It raises questions about Sun's motives in agreeing to such a deal, but it really shines the spotlight on what Microsoft thought was important to exempt from the Sun-Microsoft patent truce," she wrote in an e-mail interview.
