What this shows Access's Innovation Score is 36.6/100 (top 46% 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 Access?

Each dot is one of Access’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). Access’s own 18.3 claims/patent is ABOVE the 10.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Access's grants concentrate

Access Closure, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 88.4% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2019 (12 grants) versus a trough of 2 in 2018. By volume, Access sits between Apaq Technology Co., Ltd. and B.R.A.H.M.S GMBH.

Access's three-year grant acceleration

Access Closure, Inc. shows 10 grants in 2022–2024 against only 17 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.
