What this shows Bharat's Innovation Score is 38.3/100 (top 41% 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 Bharat?

Each dot is one of Bharat’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). Bharat’s own 13.8 claims/patent is ABOVE the 12.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Bharat's grants concentrate

Bharat Petroleum Corporation Limited is a focused PatentsView assignee: 18 CPC subclasses with 60% of grants classified under B01J (Chemical OR Physical Processes, e.g. Catalysis OR Colloid CHEMISTRY; Their Relevant Apparatus). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2018. By volume, Bharat sits between Autifony Therapeutics Limited and Baby Jogger, LLC.

Bharat's three-year grant acceleration

Bharat Petroleum Corporation Limited shows 5 grants in 2022–2024 against only 9 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.
