What this shows The's Innovation Score is 56.3/100 (top 6% 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 The's grant cadence moved

Between 2020–2024, The University of Bristol received 30 grants versus 23 in 2015–2019 (+30% equal-window velocity, above median growth). Across complete PatentsView years, output peaked in 2020 at 7 grants and bottomed in 2015 at 3. Lead class G02B accounts for 16.4% of the portfolio across 61 subclasses. Volume neighbours: The 41st Parameter, Inc. (#6,192) and University College Dublin, National University OF Ireland, Dublin (#6,200).

The's three-year grant acceleration

The University of Bristol shows 18 grants in 2022–2024 against only 18 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.
