What this shows NTT's Innovation Score is 48.5/100 (top 16% 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 NTT?

Each dot is one of NTT’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). NTT’s own 8.7 claims/patent is at or below the 9.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where NTT's grants concentrate

NTT Communications Corporation is a focused PatentsView assignee: 21 CPC subclasses with 61.4% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). Peak complete grant year is 2024 (15 grants) versus a trough of 3 in 2019. By volume, NTT sits between N.E. Chemcat Corporation and OTI Lumionics Inc..

NTT's three-year grant acceleration

NTT Communications Corporation shows 25 grants in 2022–2024 against only 12 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.
