Portfolio overview

Proterra Operating Company, Inc. has been granted 9 US utility patents between 2022 and 2023, placing Proterra Operating Company, Inc. at rank #29,832 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.1 claims per patent with primary concentration in Y02T (CLIMATE CHANGE MITIGATION TECHNOLOGIES RELATED TO TRANSPORTATION). As a US Corporation, Proterra Operating Company, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Proterra sits between Proserv Gilmore Valve Llc (9 patents, rank #29,828) and Pupil Labs Gmbh (9 patents, rank #29,836) - the closest US assignees by grant volume. The composite Innovation Score of 52.3/100 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. Historical data spans 2022 through 2023, with 9 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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 Operating Company, Inc.'s 20.1 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Proterra Operating Company, Inc. against peers pursuing similar technology classes.
