Portfolio overview

Protran Technology, Llc has been granted 5 US utility patents between 2021 and 2023, placing Protran Technology, Llc at rank #49,618 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 23.4 claims per patent with primary concentration in B61L (GUIDING RAILWAY TRAFFIC; ENSURING THE SAFETY OF RAILWAY TRAFFIC). As a US Corporation, Protran Technology, Llc is one of the more focused assignees in the PatentsView dataset. By volume, Protran sits between Propst Family Limited Partnership (5 patents, rank #49,614) and Proxene Tools Co., Ltd. (5 patents, rank #49,622) - the closest US assignees by grant volume. The composite Innovation Score of 35.9/100 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. Historical data spans 2021 through 2023, with 5 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. Protran Technology, Llc's 23.4 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Protran Technology, Llc against peers pursuing similar technology classes.
