I saw some of this up close recently and it was quite interesting how Japan was still 'fighting the last war' in this sense.
They were trying to avoid a repetition of Japanese companies doing an end-run around American and European companies by doing their manufacturing and then turning around to innovate on the processes and principles in the end resulting in a wholly new industrial base.
But the world has long moved on from that time and even though there is plenty of innovation in this sphere the threat of a manufacturer turning into a competitor is still present (for instance, in China) but between the US, the EU and Japan that threat is all but non-existent.
Japanese companies are slowly coming around on this and are becoming more free with respect to sharing technology and IP with other partners. This Panasonic move is another step in that direction.
