Some knowledge is more basic and critical for the development of an industry while some is a result of applications of such critical knowledge. To understand how knowledge emerged and developed in an industry, we examined the time course of emergence of different types of patents in PC industry. One thousand and one patents were sampled from US patent database. These patents were classified into five knowledge groups that differ in criticality to the development of PC: critical to PC technology, functional expansion of PC, accessory and parts, style design, and application of PC technology. The results showed that more critical patents appeared early and those who possessed such patents would have an advanatage in PC industry. Those that did not possess the ability to generate knowledge critical to PC industry developed patents primarily in the areas of PC accessories or parts, or PC applications. In addition, critical knowledge that spilled from filing patents tended to exert a greater influence on the development of new patents.
