What this shows Emcore's Innovation Score is 48.2/100 (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 Emcore?

Each dot is one of Emcore’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). Emcore’s own 22.8 claims/patent is ABOVE the 16.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Emcore's grants concentrate

Emcore Corporation is a focused PatentsView assignee: 18 CPC subclasses with 47.6% of grants classified under H01S (Devices Using THE Process OF Light Amplification BY Stimulated Emission OF Radiation [LASER] TO Amplify OR Generate LIGHT; Devices Using Stimulated Emission OF Electromagnetic Radiation IN Wave Ranges). Peak complete grant year is 2015 (6 grants) versus a trough of 1 in 2018. By volume, Emcore sits between Downhole Technology, LLC and Erae AMS Co., Ltd..

Emcore's three-year grant acceleration

Emcore Corporation shows 4 grants in 2022–2024 against only 3 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.
