Does more volume mean deeper claims for Taicang?

Each dot is one of Taicang’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). Taicang’s own 7.7 claims/patent is at or below the 16.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Taicang's grants concentrate

Taicang Kingfu Plastic Manufacture Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 73.3% of grants classified under E06B (Fixed OR Movable Closures FOR Openings IN Buildings, Vehicles, Fences OR Like Enclosures IN General, e.g. Doors, Windows, Blinds, Gates). Peak complete grant year is 2017 (6 grants) versus a trough of 1 in 2015. By volume, Taicang sits between Symeo GmbH and TBS Engineering Limited.

Taicang's three-year grant acceleration

Taicang Kingfu Plastic Manufacture Co., Ltd. shows 2 grants in 2022–2024 against only 2 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.
