[6] Why RF IPR – from IBM
? RAND vs RF
40
? 1995-2003 – RAND!
? 2003- present – RF!
? IBM leads the world in patents
? Hard to change internal culture
? SW & HW have diff cultures w.r.t. IPR
? For SW…the key to shifting from RAND ? RF
? RF Standards ? Bigger Markets ? More $$
? It’s a business decision!
? If standard activity is strategic, default = RF
? Glad to answer questions talk details later
