What this shows York's Innovation Score is 43.3/100 (top 28% 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 York?

Each dot is one of York’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). York’s own 12.4 claims/patent is at or below the 16.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where York's grants concentrate

York Guangzhou Air Conditioning and Refrigeration Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 36.4% of grants classified under F04D (Non-positive-displacement Pumps). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2017. By volume, York sits between YKK Corporation of America and Zephyr Photonics Inc..

York's three-year grant acceleration

York Guangzhou Air Conditioning and Refrigeration Co., Ltd. shows 5 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.
