Portfolio overview

PRAJ Industries Limited has been granted 9 US utility patents between 2019 and 2025, placing PRAJ Industries Limited at rank #29,743 across all assignees tracked by PlainPatent. This portfolio spans 19 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.0 claims per patent with primary concentration in C12P (FERMENTATION OR ENZYME-USING PROCESSES TO SYNTHESISE A DESIRED CHEMICAL COMPOUND OR COMPOSITION OR TO SEPARATE OPTICAL ISOMERS FROM A RACEMIC MIXTURE). As a Foreign Corporation, PRAJ Industries Limited is one of the more focused assignees in the PatentsView dataset. By volume, PRAJ sits between Porcher Industries (9 patents, rank #29,739) and Premo, Sa (9 patents, rank #29,747) - the closest US assignees by grant volume. The composite Innovation Score of 33.9/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 8 grants, compared with 1 in the 2015–2019 window, a +700% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. PRAJ Industries Limited's 12.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 19 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark PRAJ Industries Limited against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
