Non-educational filers ranked by their patent portfolio. Grant rate and lapsed share expose where high filing volume is not matched by granted patents. Domestic filers lead - toggle to foreign applicants to see who is entering the Indian market.

Why this page exists - and how to read it

Filing volume and IP quality are different things. This leaderboard ranks non-educational filers by portfolio, but the grant-rate and lapsed sorts are where the judgement lives: they separate companies whose filings survive examination from those accumulating paper.

Investors
High grant rate on steady filing usually means a real R&D engine; big volume with a high lapsed share is a red flag worth asking about.
Founders & operators
These are the incumbents and potential acquirers in your space - open a filer to see the walls you'd build against.
Corporate & R&D
Benchmark competitors' portfolios and grant rates; toggle to foreign to watch who is entering the Indian market.

πŸ’¬ The grant-rate sort applies a 20-filing floor so tiny portfolios can't top the list.

Educational institutes are excluded - see the institute leaderboard. Attribution is by patent assignee record; a jointly-owned patent is credited to each co-owner, so a co-filed patent counts for every company on it. "Lapsed" = abandoned, withdrawn, deemed-withdrawn or refused; "Pending" = awaiting examination or in prosecution. Want to filter by technology or value category? Browse the filer explorer β†’

Rankings use patent-registry status (grant rate, examination, claim depth) as a quality proxy - directional, not advice; see methodology. Read the ranking methodology β†’

Patent coverage: 4,84,093 applications, 84.4% filed 2022 onward, 96% carry AI-generated technology tags. Earlier records, back to 2004, are largely granted cases, so pre-2022 years show survivors rather than full filing volume.
