Does more volume mean deeper claims for Contemporary?

Each dot is one of Contemporary’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). Contemporary’s own 15.3 claims/patent is ABOVE the 13.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

How Contemporary's grant cadence moved

Grant history spans 2024–2025. Lead class H01M accounts for 81.4% of the portfolio across 102 subclasses. Volume neighbours: View, Inc. (#1,099) and Kobelco Construction Machinery Co., Ltd (#1,107).

Contemporary's three-year grant acceleration

Contemporary Amperex Technology (HONG KONG) Limited shows 87 grants in 2022–2024 against only 0 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.
