The Best Corporate Cases on Open Innovation?

I am in the early planning stage for a number of open innovation sessions in the U.S., Europe, Asia (Singapore) and South America (Brazil).

Here, I would like to present corporate insights and experiences and facilitate a discussion on where open innovation is heading and what steps companies need to take in order to reap the full potential of this movement.

I have written about many companies with noteworthy open innovation efforts and you can find some 15inno blog posts here: Beiersdorf – GE – General Mills – LEGO – P&G – Philips – Psion – Siemens – Unilever – Weyerhaueser

Which cases of open innovation in large companies can you recommend? Please also let me know if you can recommend any speakers from the companies you mention.
