What is the difference between ICR and OCR?

I've just found the term Intelligent Character Recognition (ICR) on Wikipedia and other pages. According to Wikipedia:

In computer science, intelligent character recognition (ICR) is an advanced optical character recognition (OCR) or — rather more specific — handwriting recognition system that allows fonts and different styles of handwriting to be learned by a computer during processing to improve accuracy and recognition levels.

Is this just a marketing stunt or are there actually techniques which are specified as OCR and other techniques which are ICR? Are there Conferences / Journals about OCR which distinguish between OCR and ICR? (If yes, please add a reference)
