I have currently 13 US patents and 13 Japanese patents already registered.  Further more, 12 patents application in Japan were opened to the public and still pending.  Another patent application in Japan was applied but was not opened to the public and especially treated as a Know-How patent.  This is the special patent law available only in Japan.  Such Know-How patent is not publicly exhibited but can be used as a prioritized revealed document.

All these patents were derived from actual product design work related to desk-top calculator, video game, CRT graphics, and flat panel graphics.  They all have been actually applied to a couple of LSI products in which I was involved intensively.  They are not simple idea on the desk that has not been applied on actual products.  Because such LSI products were physically exported all over the world, we had to apply US patents in addition to regular Japanese patents although getting a patent registration from Japanese patent agency is much more difficult than the case of US.

All Japanese patents were applied in Japan and registered.  Other IPC patent applications for Europe were omitted here.

Engineers have to be creative all the time and go for a dream.
