碩士 / 國立臺灣科技大學 / 專利研究所 / 103 / Algae are the origin of life on Earth. As we have seen, oceans cover more than 70％ of the earth. Therefore, algae are the main sources of oxygen that are produced by photosynthesis. They are at the bottom of the food chain and the main producers in the environment.
In recent years, because the emerging of biotechnology, algae's several functions have been discovered. Algae's nutritional value is very high because they contain antioxidants, polysaccharides, and more than 28% of protein. The history of algae consumption can be traced back to World War I. In order to solve the food shortage problem, Germany began to study the consumption of green algae.
In addition to edibility, there are many other uses, for example: fertilizers feed, medicinal properties, industrial, renewable energy sources, waste water treatment, biodiesel, electric power and so on. The algae extracts can also be applied to cosmetics. Their extractions and separations of the ingredients have many effects, such as whitening, moisturizing, anti-aging, and anti-inflammatory. They can increase elasticity of skin and reduce skin oil, melanin and spots. According to the consumer market tendencies, consumers tend to buy cosmetic products that are made from natural ingredients. For this reason, algae cosmetic products have become an attractive topic for research. Moreover, the patent portfolio related to cosmetic company is different from the patent portfolio of the electronic industries. It is a very valuable research target, because of its particular phenomenon.
In this paper, patent portfolio was executed by complete patent search procedure. We analyzed patent application trends, competitive companies, patent family and crucial patents. By the analysis, we can provide related patent and information to companies as a reference.
