Does more volume mean deeper claims for Xjet?
Each dot is one of Xjet’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). Xjet’s own 14.6 claims/patent is at or below the 15.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Xjet's grants concentrate
Xjet Ltd. is a focused PatentsView assignee: 18 CPC subclasses with 70% of grants classified under B41J (TYPEWRITERS; Selective Printing Mechanisms, i.e. Mechanisms Printing Otherwise Than From A FORME; Correction OF Typographical Errors). Peak complete grant year is 2016 (3 grants) versus a trough of 2 in 2015. By volume, Xjet sits between Willow Garage, LLC and Yamaha Motor Power Products Kabushiki Kaisha.
Xjet's three-year grant acceleration
Xjet Ltd. shows 4 grants in 2022–2024 against only 9 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.
