What this shows Protec's Innovation Score is 43.1/100 (top 29% 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 Protec?

Each dot is one of Protec’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). Protec’s own 11.2 claims/patent is at or below the 17.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Protec's grants concentrate

Protec Co., Ltd. is a focused PatentsView assignee: 30 CPC subclasses with 43.2% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2019 (7 grants) versus a trough of 1 in 2023. By volume, Protec sits between Oxylabs, UAB and Pulse Finland OY.

Protec's three-year grant acceleration

Protec Co., Ltd. shows 8 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.
