What this shows Myung's Innovation Score is 32.0/100 (40th 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 Myung?

Each dot is one of Myung’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). Myung’s own 8.2 claims/patent is at or below the 18.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Myung's grants concentrate

Myung HWA IND. Co., Ltd. is a focused PatentsView assignee: 16 CPC subclasses with 53.3% of grants classified under F04C (Rotary-piston, OR Oscillating-piston, Positive-displacement Machines FOR Liquids ; Rotary-piston, OR Oscillating-piston, Positive-displacement Pumps). Peak complete grant year is 2015 (3 grants) versus a trough of 1 in 2020. By volume, Myung sits between Midea America Corp. and Marelli Cabin Comfort Japan Corporation.

Myung's three-year grant acceleration

Myung HWA IND. Co., Ltd. shows 3 grants in 2022–2024 against only 6 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.
