In the age of Knowledge-based Economy, knowledge will become the main motive power of economic growth. Patent, as one of the indicators of intellectual properties, is suitable for measuring the competition potential, technology capabilities, and innovation performance of corporations. In the model of mass production and fast manufacturing, the price of goods decrease acutely and getting the Taiwanese corporations into the low margin age. How to make the most of intellectual properties and patents to increase the additional value is the key to success. Taiwanese companies had starting to apply for patents in many countries, but the licensing fee and litigation are still in high level. That express that the qualities and quantities of the patents are still not enough to cover the technologies and products of Taiwanese companies. This study takes computer heat dissipation industry for example, and using the patent analysis, Logistic curve, and patent strategy matrix to discuss the patent application and patent strategy. The research result shows that the computer heat dissipation industry is in the mature stage, the degree of patent is crowded, and the rate of change is slow. Most of the Taiwanese companies are small scale and not good at inventing in the most advanced technologies. Especially in this mature industry, this study suggest Taiwanese corporations should take licensing, avoiding existing patents, and improvement development as basic patent strategies. Not to apply lots of patents in small scope to suit each other, but should establish patent alliance or co-development, even join or make the industry standard to earn competition advantages.
