What this shows Champ's Innovation Score is 45.0/100 (top 24% 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 Champ?

Each dot is one of Champ’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). Champ’s own 11.8 claims/patent is ABOVE the 9.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Champ's grants concentrate

Champ Tech Optical (FOSHAN) Corporation is a focused PatentsView assignee: 31 CPC subclasses with 36.8% of grants classified under F04D (Non-positive-displacement Pumps). Peak complete grant year is 2019 (6 grants) versus a trough of 1 in 2015. By volume, Champ sits between Beta-Calco, Inc. and Cyclingdeal USA, Inc..

Champ's three-year grant acceleration

Champ Tech Optical (FOSHAN) Corporation shows 10 grants in 2022–2024 against only 12 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.
