Intellectual Property
The Sender ID proposal was the subject of controversy regarding intellectual property licensing issues: Microsoft holds patents on key parts of Sender ID and used to license those patents under terms that were not compatible with the GNU General Public License and which were considered problematic for free software implementations in general. On October 23, 2006, Microsoft placed those patents under the Open Specification Promise, which is compatible with free and open source licenses, but not with the most recent version of the GPL license, version 3.x.

Famous quotes containing the words intellectual and/or property:
“And what, then, is belief? It is the demi-cadence which closes a musical phrase in the symphony of our intellectual life.”
—Charles Sanders Peirce (1839–1914)
“The charming landscape which I saw this morning is indubitably made up of some twenty or thirty farms. Miller owns this field, Locke that, and Manning the woodland beyond. But none of them owns the landscape. There is property in the horizon which no man has but he whose eye can integrate all parts, that is, the poet. This is the best part of these men’s farms, yet to this their warranty-deeds give no title.”
—Ralph Waldo Emerson (1803–1882)
