What this shows Tearclear's Innovation Score is 40.0/100 (top 37% 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 Tearclear?

Each dot is one of Tearclear’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). Tearclear’s own 23.1 claims/patent is ABOVE the 12.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Tearclear's grants concentrate

TearClear Corp. is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under A61F (Filters Implantable Into Blood VESSELS; PROSTHESES; Devices Providing Patency TO, OR Preventing Collapsing OF, Tubular Structures OF THE Body, e.g. STENTS; Orthopaedic, Nursing OR Contraceptive Device). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2022. By volume, Tearclear sits between Tate Consultancy Services Limited and Technelec Ltd.

Tearclear's three-year grant acceleration

TearClear Corp. shows 4 grants in 2022–2024 against only 3 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.
