Where have they used royalty before to describe a license agreement.

Nokia PR:
Since January 2006, HP (NYSE: HPQ), Casio, Fujitsu, Sony (NYSE: SNE), Nikon, Seiko Epson, Pentax, Olympus, Kenwood, Agilent (NYSE: A), Lexmark, Schneider Electric, NEC Corporation, Funai Electric, SanDisk (NSDQ: SNDK) and Sharp Corporation have all purchased MMP Portfolio licenses. The licensing program rewards early movers in specific industry segments by subjecting subsequent licensees in those same segments to progressively higher royalty rates.

Bull PR:
Patriot and Alliacense have established a highly successful global licensing program whereby royalty rates increase over time as the number licensees grows and uncertainties regarding the patented MMP technology are resolved.
