What this shows Longi's Innovation Score is 41.2/100 (top 34% 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 Longi?

Each dot is one of Longi’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). Longi’s own 10.9 claims/patent is at or below the 11.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Longi's grants concentrate

Longi Solar Technology (TAIZHOU) Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under H10F (Inorganic Semiconductor Devices Sensitive TO Infrared Radiation, Light, Electromagnetic Radiation OF Shorter Wavelength OR Corpuscular Radiation). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2021. By volume, Longi sits between Lkab Wassara AB and Lubing Maschinenfabrik Ludwig Bening GMBH & Co. KG.

Longi's three-year grant acceleration

Longi Solar Technology (TAIZHOU) Co., Ltd. shows 3 grants in 2022–2024 against only 1 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.
