Does more volume mean deeper claims for Tearscience?

Each dot is one of Tearscience’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). Tearscience’s own 28.3 claims/patent is ABOVE the 13.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Tearscience's grants concentrate

Tearscience, Inc. is a focused PatentsView assignee: 10 CPC subclasses with 88.6% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2017 (8 grants) versus a trough of 1 in 2022. By volume, Tearscience sits between THE State OF Israel, Ministry OF Agriculture & Rural Development, Agricultural Research Organization (ARO) (VOLCANI CENTER) and The New Zealand Institute for Plant and Food Research Limited.

Tearscience's three-year grant acceleration

Tearscience, Inc. shows 3 grants in 2022–2024 against only 12 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.
