看美国申请的专利，claim中经常会出现不同的矛盾的给药情况，例如eylea的claim中有：
5. The method of claim 4, wherein the initial dose is at least approximately 50 micrograms of VEGF inhibitor protein.
6. The method of claim 5, wherein the initial dose is at least approximately 100 micrograms of VEGF inhibitor protein.
7. The method of claim 6, wherein the initial dose is at least approximately 1000 micrograms of VEGF inhibitor protein.
8. The method of claim 4, wherein the subsequent doses are separated in time from each other by at least four weeks.
9. The method of claim 8, wherein the subsequent doses are separated in time from each other by at least 3 to 6 months.
这里面的567，还有8和9是啥关系啊？
