What this shows Anji's Innovation Score is 40.2/100 (top 36% 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 Anji?

Each dot is one of Anji’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). Anji’s own 10.2 claims/patent is ABOVE the 7.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Anji's grants concentrate

Anji Microelectronics (Shanghai) Co. Ltd is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under C09G (Polishing Compositions ; SKI Waxes). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2023. By volume, Anji sits between Anhui New Star Pharmaceutical Development Co., Ltd and Annex Medical, Inc..

Anji's three-year grant acceleration

Anji Microelectronics (Shanghai) Co. Ltd shows 3 grants in 2022–2024 against only 0 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.
