Who invented the Pen Drive?

I happened to see a programme in Astro AEC today which highlighted the inventor of the pen drive was a young engineer from Sekinchan in the State of Selangor in Malaysia!

His name is Khein-Seng Pua. However, he migrated to Taiwan & the pen drive invention is accredited to the company he worked in.

Now this is very interesting indeed. There were a lot of contradiction as to the invention of the pen drive & nobody wants to be left out, Samsung, IBM, etc

See link here http://tech.groups.yahoo.com/group/macri-group/message/3978?threaded=1&var=1&p=13. to read some interesting correspondence from another Malaysian inventor Robest Yong who hails from the Methodist Secondary School, Nibong Tebal, Penang, Malaysia.
