Reuters reported that "Commercial developers such as IBM or Red Hat must pay a license fee of 0.4 percent of revenues to Microsoft when they redistribute that software, to protect against patent challenges."

Commissioner Kroes has said, of the deal, "That percentage royalty has become a nominal, one-off payment of Euro 10,000. This is all that has to be paid by companies that dispute the validity or relevance of Microsoft's patents

The Linux Foundation supports the adoption of open standards as a catylist for innovation and to define common frameworks for new development. With ODF (Open Document Format) as an existing ISO document standard, we do not consider it beneficial to introduce an alternative document standard. Since ODF and OOXML are both designed as formats for editable documents, computer users would greatly benefit from multiple implementations of a single standard rather than suffer the confusion, conversions, and incompatibilities involved with multiple standards

The Linux Foundation also supports the activities of the Desktop Architects and they have spoken out on why DIS29500 “Office Open XML” (OOXML) does not meet the criteria defined by ISO and others for an International Standard. In a Grocklaw posting, Google provided their position on OOXML as a Proposed ISO Standard. They suggest that if Microsoft wishes to create a document format that is better able to address the problems of the many editable legacy documents created in their older proprietary formats that they are welcome to help extend the existing ODF ISO standard in order to add the capabilities they require.
