What this shows PLX's Innovation Score is 40.7/100 (top 35% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for PLX?

Each dot is one of PLX’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). PLX’s own 20.0 claims/patent is ABOVE the 9.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where PLX's grants concentrate

PLX, Inc. is a focused PatentsView assignee: 12 CPC subclasses with 87.5% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2016. By volume, PLX sits between Pkware, Inc. and Premier Tech Technologies L TÉE.

PLX's three-year grant acceleration

PLX, Inc. shows 4 grants in 2022–2024 against only 4 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.
