What this shows Exergyn's Innovation Score is 55.3/100 (top 7% 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.

How Exergyn's grant cadence moved

Between 2020–2024, Exergyn, Ltd. received 32 grants versus 27 in 2015–2019 (+19% equal-window velocity, above median growth). Across complete PatentsView years, output peaked in 2023 at 10 grants and bottomed in 2015 at 3. Lead class F03G accounts for 27% of the portfolio across 77 subclasses. Volume neighbours: Century Technology (Shenzhen) Corporation Limited (#5,433) and Guangdong Huanengda Electrical Appliances Co., Ltd (#5,441).

Exergyn's three-year grant acceleration

Exergyn, Ltd. shows 22 grants in 2022–2024 against only 16 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.
