Does more volume mean deeper claims for Sifotonics?
Each dot is one of Sifotonics’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). Sifotonics’s own 16.8 claims/patent is ABOVE the 14.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Sifotonics's grants concentrate
SiFotonics Technologies Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 54.3% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2016 (9 grants) versus a trough of 1 in 2023. By volume, Sifotonics sits between Safe Rack LLC and Spiration, Inc..
Sifotonics's three-year grant acceleration
SiFotonics Technologies Co., Ltd. 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.
