Does more volume mean deeper claims for Yantai?
Each dot is one of Yantai’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). Yantai’s own 16.9 claims/patent is ABOVE the 15.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
How Yantai's grant cadence moved
Grant history spans 2020–2025. Across complete PatentsView years, output peaked in 2024 at 53 grants and bottomed in 2020 at 5. Lead class E21B accounts for 74.5% of the portfolio across 62 subclasses. Volume neighbours: Positec Power Tools (Suzhou) Co., Ltd. (#2,426) and Feitian Technologies Co., Ltd. (#2,434).
Yantai's three-year grant acceleration
Yantai Jereh Petroleum Equipment & Technologies Co., Ltd. shows 107 grants in 2022–2024 against only 12 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.
