What this shows Corning's Innovation Score is 48.4/100 (top 17% 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 Corning?

Each dot is one of Corning’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). Corning’s own 12.6 claims/patent is at or below the 14.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Corning's grant cadence moved

Between 2020–2024, Corning Precision Materials Co., Ltd. received 4 grants versus 75 in 2015–2019 (-95% equal-window velocity, below median growth). Across complete PatentsView years, output peaked in 2018 at 21 grants and bottomed in 2020 at 2. Lead class H10K accounts for 45.6% of the portfolio across 51 subclasses. Volume neighbours: BioVentures, LLC (#4,455) and Elan Microelectronics Corporation (#4,463).

Corning's three-year grant acceleration

Corning Precision Materials Co., Ltd. shows 2 grants in 2022–2024 against only 19 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.
