Does more volume mean deeper claims for Silk?

Each dot is one of Silk’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). Silk’s own 15.9 claims/patent is ABOVE the 11.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Silk's grants concentrate

Silk Technologies, Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2016. By volume, Silk sits between Siemens Concentrated Solar Power Ltd. and SKC Hi-tech & Marketing Co., Ltd..

Silk's three-year grant acceleration

Silk Technologies, Ltd. shows 2 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.
