Does more volume mean deeper claims for Amphenol?
Each dot is one of Amphenol’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). Amphenol’s own 16.9 claims/patent is at or below the 17.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Amphenol's grants concentrate
Amphenol Assembletech (XIAMEN) Co., Ltd is a focused PatentsView assignee: 4 CPC subclasses with 78.6% of grants classified under H01R (Electrically-conductive CONNECTIONS; Structural Associations OF A Plurality OF Mutually-insulated Electrical Connecting ELEMENTS; Coupling DEVICES; Current Collectors). Peak complete grant year is 2021 (5 grants) versus a trough of 1 in 2019. By volume, Amphenol sits between Alto Memory Technology Corporation and Apex Artificial Intelligence Industries, Inc..
Amphenol's three-year grant acceleration
Amphenol Assembletech (XIAMEN) Co., Ltd shows 5 grants in 2022–2024 against only 7 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.
