What this shows Zygo's Innovation Score is 48.5/100 (top 16% 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 Zygo?

Each dot is one of Zygo’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). Zygo’s own 27.4 claims/patent is ABOVE the 9.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zygo's grants concentrate

Zygo Corporation is a focused PatentsView assignee: 18 CPC subclasses with 62.5% of grants classified under G01B (Measuring Length, Thickness OR Similar Linear DIMENSIONS; Measuring ANGLES; Measuring AREAS; Measuring Irregularities OF Surfaces OR Contours). Peak complete grant year is 2015 (11 grants) versus a trough of 2 in 2020. By volume, Zygo sits between X-Card Holdings, LLC and Airbus.

Zygo's three-year grant acceleration

Zygo Corporation shows 6 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.
