What this shows Seal-ryt's Innovation Score is 32.2/100 (40th 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 Seal-ryt?

Each dot is one of Seal-ryt’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). Seal-ryt’s own 9.6 claims/patent is at or below the 13.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Seal-ryt's grants concentrate

Seal-ryt Corp. is a focused PatentsView assignee: 8 CPC subclasses with 62.5% of grants classified under F16J (Pistons ; CYLINDERS; Sealings). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2015. By volume, Seal-ryt sits between Savioke Inc. and Seibu Giken Co., Ltd..

Seal-ryt's three-year grant acceleration

Seal-ryt Corp. shows 5 grants in 2022–2024 against only 5 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.
