Portfolio overview

GS Cleantech Corporation has been granted 12 US utility patents between 2015 and 2020, placing GS Cleantech Corporation at rank #22,645 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.6 claims per patent with primary concentration in C12F (RECOVERY OF BY-PRODUCTS OF FERMENTED SOLUTIONS ; DENATURED ALCOHOL; PREPARATION THEREOF). As a US Corporation, GS Cleantech Corporation is one of the more focused assignees in the PatentsView dataset. By volume, GS sits between GPI Systems AB (12 patents, rank #22,641) and Garantir Llc (12 patents, rank #22,649) - the closest US assignees by grant volume. The composite Innovation Score of 32.6/100 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 1 grants, compared with 11 in the 2015–2019 window, a -91% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US 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. GS Cleantech Corporation's 12.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 21 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark GS Cleantech Corporation 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.
