Portfolio overview

Proterra Ag, Inc. has been granted 67 US utility patents between 2015 and 2023, placing Proterra Ag, Inc. at rank #5,179 across all assignees tracked by PlainPatent. This portfolio spans 31 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.9 claims per patent with primary concentration in Y02T (CLIMATE CHANGE MITIGATION TECHNOLOGIES RELATED TO TRANSPORTATION). As a US Corporation, Proterra Ag, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Proterra sits between National University Of Ireland, Galway (67 patents, rank #5,175) and Sony Interactive Entertainment Europe Limited (67 patents, rank #5,183) - the closest US assignees by grant volume. The composite Innovation Score of 47.9/100 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 23 grants, compared with 44 in the 2015–2019 window, a -48% 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. Proterra Ag, Inc.'s 18.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 31 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Proterra Ag, Inc. 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.
