What this shows Phichem's Innovation Score is 47.0/100 (top 19% 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 Phichem?

Each dot is one of Phichem’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). Phichem’s own 15.2 claims/patent is at or below the 19.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Phichem's grants concentrate

Phichem Corporation is a focused PatentsView assignee: 11 CPC subclasses with 60% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2023. By volume, Phichem sits between Peyton Ventures, LLC and Phinge Corporation.

Phichem's three-year grant acceleration

Phichem Corporation shows 4 grants in 2022–2024 against only 0 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.
