What this shows Fibercore's Innovation Score is 30.7/100 (35th 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 Fibercore?

Each dot is one of Fibercore’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). Fibercore’s own 15.8 claims/patent is at or below the 16.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Fibercore's grants concentrate

Fibercore Limited is a focused PatentsView assignee: 11 CPC subclasses with 40% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells). By volume, Fibercore sits between Ferdinand Lusch GmbH & Co. KG and Filmic Inc..

Fibercore's three-year grant acceleration

Fibercore Limited shows 1 grants in 2022–2024 against only 2 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.
