Does more volume mean deeper claims for Sightglass?

Each dot is one of Sightglass’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). Sightglass’s own 19.3 claims/patent is ABOVE the 15.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Sightglass's grants concentrate

SightGlass Vision, Inc. is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under G02C (SPECTACLES; Sunglasses OR Goggles Insofar AS They Have THE Same Features AS SPECTACLES; Contact Lenses). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2021. By volume, Sightglass sits between Siebel Systems, Inc. and Silicon Precision Industries Co., Ltd..

Sightglass's three-year grant acceleration

SightGlass Vision, Inc. shows 4 grants in 2022–2024 against only 1 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.
