The patent bonus at Nokia was just that, a patent bonus; the purpose of the program was to systematically collect a large portfolio of patents; such a patent mass is used in IPR negotiations with other technology giants. Those patents were mass-produced - I got paid for one too - but I wouldn't call them "inventions".

There were other, substantially larger bonuses for innovations made by staff, when these innovations had larger economical impact (for instance, optimizing the production line).
