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:
“The most intellectual of men are moved quite as much by the circumstances which they are used to as by their own will. The active voluntary part of a man is very small, and if it were not economised by a sleepy kind of habit, its results would be null.”
—Walter Bagehot (1826–1877)
“I would gladly chastise those who represent things as different from what they are. Those who steal property or make counterfeit money are punished, and those ought to be still more severely dealt with who steal away or falsify the good name of a prince.”
—Elizabeth I (1533–1603)
