What this shows Yantai's Innovation Score is 38.4/100 (top 41% 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 Yantai?

Each dot is one of Yantai’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). Yantai’s own 12.6 claims/patent is ABOVE the 11.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Yantai's grants concentrate

Yantai Shougang Magnetic Materials Inc is a focused PatentsView assignee: 11 CPC subclasses with 95% of grants classified under H01F (MAGNETS; INDUCTANCES; TRANSFORMERS; Selection OF Materials FOR Their Magnetic Properties). Peak complete grant year is 2024 (6 grants) versus a trough of 1 in 2023. By volume, Yantai sits between Xtone, Inc. and Zhejiang University OF Science AND Technology.

Yantai's three-year grant acceleration

Yantai Shougang Magnetic Materials Inc shows 9 grants in 2022–2024 against only 7 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.
