Image Hyperlinking Patent

A Singapore company claims a patent on hyperlinked images. Akin to the BT patent claimed on all hyperlinking. I recall an attorney cautioning me about linking online because of that patent(!). Eventually that patent was invalidated. That reminds me of a knowledge management system I wrote that used hyperlinking. This was early 80s, long before the Web. The concept had been around for some time. Ted Nelson is considered the parent of hyperlinking, as far back as 1965, for a future look at the idea see his ZigZag idea. An intro to its architecture.
