What this shows Hydro-quebec's Innovation Score is 61.4/100 (top 3% 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 Hydro-quebec?

Each dot is one of Hydro-quebec’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). Hydro-quebec’s own 20.4 claims/patent is ABOVE the 14.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

How Hydro-quebec's grant cadence moved

Between 2020–2024, Hydro-Quebec received 34 grants versus 42 in 2015–2019 (-19% equal-window velocity, below median growth). Across complete PatentsView years, output peaked in 2016 at 15 grants and bottomed in 2019 at 4. Lead class Y02E accounts for 75% of the portfolio across 67 subclasses. Volume neighbours: Extang Corporation (#4,620) and Kinestral Technologies, Inc. (#4,628).

Hydro-quebec's three-year grant acceleration

Hydro-Quebec 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.
