What this shows Hieta's Innovation Score is 52.6/100 (top 10% 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.

Where Hieta's grants concentrate

Hieta Technologies Limited is a focused PatentsView assignee: 17 CPC subclasses with 66.7% of grants classified under F28D (Heat-exchange Apparatus, NOT Provided FOR IN Another Subclass, IN Which THE Heat-exchange Media DO NOT Come Into Direct Contact). Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2018. By volume, Hieta sits between Heys International Ltd. and Hitachi Automotive Systems Kyushu, Ltd..

Hieta's three-year grant acceleration

Hieta Technologies Limited shows 6 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.
