What this shows NTT's Innovation Score is 35.9/100 (top 48% 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 17.4 claims/patent is ABOVE the 11.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where NTT's grants concentrate

NTT Research, Inc. is a focused PatentsView assignee: 8 CPC subclasses with 80% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2021. By volume, NTT sits between Nanopharmaceuticals LLC and National Institute of Biological Sciences, Beijing.

NTT's three-year grant acceleration

NTT Research, Inc. shows 3 grants in 2022–2024 against only 4 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.
