Does more volume mean deeper claims for FEI?
Each dot is one of FEI’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). FEI’s own 18.7 claims/patent is ABOVE the 16.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
How FEI's grant cadence moved
Between 2020–2024, FEI Company received 218 grants versus 250 in 2015–2019 (-13% equal-window velocity, above median growth). Across complete PatentsView years, output peaked in 2015 at 64 grants and bottomed in 2019 at 39. Lead class H01J accounts for 84.3% of the portfolio across 70 subclasses. Volume neighbours: Entegris, Inc. (#890) and China Petroleum & Chemical Corporation (#898).
FEI's three-year grant acceleration
From 2019–2021 to 2022–2024, FEI Company moved from 126 to 131 grants (1.04x the prior three-year total, a multiple, not a CAGR). Among 3,296 tracked assignees with ≥100 grants and ≥20 prior-period grants, that multiple ranks #1,081. See the growth leaderboard.
