What this shows TDF's Innovation Score is 34.4/100 (47th 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 TDF?

Each dot is one of TDF’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). TDF’s own 13.2 claims/patent is ABOVE the 9.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where TDF's grants concentrate

TDF is a focused PatentsView assignee: 9 CPC subclasses with 35.3% of grants classified under H04N (Pictorial Communication, e.g. Television). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2017. By volume, TDF sits between Tabuchi Electric Co., Ltd. and Teqball Holding S.A.R.L..

TDF's three-year grant acceleration

TDF shows 7 grants in 2022–2024 against only 8 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.
