What this shows Unitika's Innovation Score is 50.8/100 (top 12% 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 Unitika?

Each dot is one of Unitika’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). Unitika’s own 9.0 claims/patent is at or below the 17.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Unitika's grant cadence moved

Between 2020–2024, Unitika Ltd. received 27 grants versus 25 in 2015–2019 (+8% equal-window velocity, above median growth). Across complete PatentsView years, output peaked in 2015 at 8 grants and bottomed in 2016 at 2. Lead class C08J accounts for 37.9% of the portfolio across 63 subclasses. Volume neighbours: Trinamix GMBH (#5,895) and VLT, Inc. (#5,903).

Unitika's three-year grant acceleration

Unitika Ltd. shows 16 grants in 2022–2024 against only 17 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.
