What this shows Won-door's Innovation Score is 42.6/100 (top 30% 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 Won-door?

Each dot is one of Won-door’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). Won-door’s own 19.5 claims/patent is ABOVE the 16.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Won-door's grants concentrate

Won-Door Corporation is a focused PatentsView assignee: 21 CPC subclasses with 66.7% of grants classified under E05Y (Indexing Scheme Associated With Subclasses E05d AND E05f, Relating TO Construction Elements, Electric Control, Power Supply, Power Signal OR Transmission, User Interfaces, Mounting OR Coupling, Detail). Peak complete grant year is 2015 (10 grants) versus a trough of 1 in 2018. By volume, Won-door sits between Voxer IP LLC and AIT Austrian Institute OF Technology GMBH.

Won-door's three-year grant acceleration

Won-Door Corporation shows 3 grants in 2022–2024 against only 9 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.
