What this shows Kingfa's Innovation Score is 34.3/100 (47th 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 Kingfa?

Each dot is one of Kingfa’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). Kingfa’s own 14.3 claims/patent is ABOVE the 10.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kingfa's grants concentrate

Kingfa SCI. & Tech. Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 75.9% of grants classified under C08K (Use of inorganic or non-macromolecular organic substances as compounding ingredients). Peak complete grant year is 2020 (10 grants) versus a trough of 1 in 2015. By volume, Kingfa sits between JSW Aktina System Co., Ltd. and LEM Intellectual Property SA.

Kingfa's three-year grant acceleration

Kingfa SCI. & Tech. Co., Ltd. shows 6 grants in 2022–2024 against only 18 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.
