What this shows Erda's Innovation Score is 37.4/100 (top 44% 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 Erda?

Each dot is one of Erda’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). Erda’s own 27.3 claims/patent is ABOVE the 14.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Erda's grants concentrate

Erda Master Ipco Limited is a focused PatentsView assignee: 10 CPC subclasses with 66.7% of grants classified under F25B (Refrigeration Machines, Plants OR SYSTEMS; Combined Heating AND Refrigeration SYSTEMS; Heat Pump Systems). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2018. By volume, Erda sits between EPtronics, Inc. and Escapex Limited.

Erda's three-year grant acceleration

Erda Master Ipco Limited 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.
