Knowledge Management and Innovation in Organizations

I have read a lot about the importance of knowledge management and innovation in organizations. But what I would love to read and hear about is how organizations have actually managed to ensure that knowledge that they manage actually leads to increase in innovation. Is their any study conducted that actually measures how knowledge management increase in innovation in organizations. I have seen organizations do try identifying what the best practices are in their respective organizations but do organiations have any model by which they monitor whether these best practices are reused. Also do organizations have a so called an inovations board which keeps a track of innovations generated in a organization, helps register IPs etc. I would love to hear how organizations like Canon, IBM, 3M encourgage innovation. Is the presence of a strong knowledge management practice in these organizations the actual reason why these organizations register the maximum amount IPs every year?
