What this shows Essentra's Innovation Score is 33.9/100 (46th percentile 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 Essentra?

Each dot is one of Essentra’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). Essentra’s own 16.4 claims/patent is at or below the 16.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Essentra's grants concentrate

Essentra Filter Products Development Co. Pte. Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 83.3% of grants classified under A24D (CIGARS; CIGARETTES; Tobacco Smoke FILTERS; Mouthpieces FOR Cigars OR CIGARETTES; Manufacture OF Tobacco Smoke Filters OR Mouthpieces). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2016. By volume, Essentra sits between Escient Pharmaceuticals, Inc. and Everest Networks, Inc..

Essentra's three-year grant acceleration

Essentra Filter Products Development Co. Pte. Ltd. shows 3 grants in 2022–2024 against only 5 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.
