What this shows Guardnec's Innovation Score is 31.5/100 (38th percentile 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 Guardnec?

Each dot is one of Guardnec’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). Guardnec’s own 13.4 claims/patent is ABOVE the 11.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Guardnec's grants concentrate

Guardnec Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 40% of grants classified under C01B (Non-metallic ELEMENTS; Compounds THEREOF; ; Metalloids OR Compounds Thereof NOT Covered BY Subclass C01c). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2015. By volume, Guardnec sits between Guangzhou Qingkuai Innovation Technology Co., Ltd. and GUY A. Shaked Investments Ltd..

Guardnec's three-year grant acceleration

Guardnec Co., Ltd. shows 1 grants in 2022–2024 against only 1 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.
