Does more volume mean deeper claims for Nanjing?
Each dot is one of Nanjing’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). Nanjing’s own 10.2 claims/patent is ABOVE the 6.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Nanjing's grants concentrate
Nanjing Institute OF Microinterface Technology Co., Ltd is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under B01J (Chemical OR Physical Processes, e.g. Catalysis OR Colloid CHEMISTRY; Their Relevant Apparatus). By volume, Nanjing sits between Namsung Corporation and Nano Spark, Inc..
Nanjing's three-year grant acceleration
Nanjing Institute OF Microinterface Technology Co., Ltd shows 4 grants in 2022–2024 against only 0 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.
