What this shows Hefei's Innovation Score is 34.5/100 (48th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Hefei?

Each dot is one of Hefei’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Hefei’s own 15.0 claims/patent is ABOVE the 9.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hefei's grants concentrate

Hefei Lifeon Pharmaceutical Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 60% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2020. By volume, Hefei sits between Heateflex Corporation and Heimiao Technology (Shenzhen) Co., Ltd..

Hefei's three-year grant acceleration

Hefei Lifeon Pharmaceutical Co., Ltd. shows 3 grants in 2022–2024 against only 2 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
