Using QPrinter in Qt 4.8 to produce a PDF document yields a Nokia copyright in the metadata of the generated file (specifically the producer field):
(C) 2011 Nokia Corporation and/or its subsidiary(-ies)
I traced this back to QPdfEnginePrivate::writeInfo(). Looking in Qt 5 I see the same thing only the copyright holder has changed to Digia:
(C) 2012 Digia Plc and/or its subsidiary(-ies)
I am not a lawyer, but this seems to imply that Nokia/Digia is asserting a copyright claim to content I created. Now preceding the copyright notice is the Qt version (from QT_VERSION_STR), which got me thinking that perhaps a trademark claim was trying to be asserted on the name "Qt" but was incorrectly executed as a copyright claim.
I think the copyright notice in QPdfEnginePrivate::writeInfo() either needs to be removed or changed to a trademark notice.
