Application of patent map in elderly medical products - a case study of HRV wearable devices

In recent years, the development of technologies and medical devices has made the birth rate and mortality decline and this leads to the widespread phenomenon of global aging and the trend of aged society. Through the continuous verification by the collection of daily data and with the help of recording the physiological state, patients receive more accurate treatments. The heart rate variability (HRV) wearable devices were selected as the case study to investigate the strategy for devices' intellectual property rights. The unique technical keywords and search strategy of patents that are used by several of the key manufacturers were determined for systematic classification and statistical analyses so that a patent map can be generated. The product feature map and the patent activity map can be derived from the information within the patent map in order to compare with the actual market situation. This approach is to assess whether the patent analysis of this product is consistent with the market situation.
