What this shows CTF's Innovation Score is 46.8/100 (top 20% 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 CTF?

Each dot is one of CTF’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). CTF’s own 13.7 claims/patent is at or below the 16.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where CTF's grants concentrate

CTF Solar GmbH is a focused PatentsView assignee: 8 CPC subclasses with 90.9% of grants classified under H10F (Inorganic Semiconductor Devices Sensitive TO Infrared Radiation, Light, Electromagnetic Radiation OF Shorter Wavelength OR Corpuscular Radiation). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2017. By volume, CTF sits between CSR Building Products Limited and Czech Technical University IN Prague.

CTF's three-year grant acceleration

CTF Solar GmbH shows 6 grants in 2022–2024 against only 2 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.
