Does more volume mean deeper claims for En?
Each dot is one of En’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). En’s own 19.7 claims/patent is ABOVE the 17.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where En's grants concentrate
En RX Chemical, Inc. is a focused PatentsView assignee: 5 CPC subclasses with 66.7% of grants classified under B09C (Reclamation OF Contaminated Soil). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2020. By volume, En sits between Emomo Technology (Zhejiang) Co., Ltd. and Endliss Technology, Inc..
En's three-year grant acceleration
En RX Chemical, Inc. shows 2 grants in 2022–2024 against only 4 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.
