RESULTS & CONCLUSIONS:Patent eligibility required that patent protection objects should be included in ob-ject range which could be vested patent right stated in patent law. The analysis of“Mayo case”“Myriad case”and patent eligibility guideline indicated that if related Chinese medicines’patent was to obtain patent approval in the United States,notable difference between the medicine and natural products as well as the order of nature must be clearly stated;technical attributes should be em-phasized,and different patent application ideas were adopted for different types of invention in order to guarantee patent eligibility.
