What this shows Sungilturbine's Innovation Score is 27.5/100 (24th 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 Sungilturbine?

Each dot is one of Sungilturbine’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). Sungilturbine’s own 10.0 claims/patent is at or below the 15.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sungilturbine's grants concentrate

Sungilturbine Co., Ltd is a focused PatentsView assignee: 9 CPC subclasses with 50% of grants classified under C10L (Fuels NOT Otherwise Provided FOR; Natural GAS; Synthetic Natural GAS Obtained BY Processes NOT Covered BY Subclasses C10g OR C10K; Liquified Petroleum GAS; USE OF Additives TO Fuels OR FIRES; Fire-lig). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2018. By volume, Sungilturbine sits between SUN Electronic Industries Corp. and Sunsea Telecommunications Co., Ltd..

Sungilturbine's three-year grant acceleration

Sungilturbine Co., Ltd shows 1 grants in 2022–2024 against only 2 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.
