Portfolio overview

Leviton Manufacturing Co., Inc. has been granted 222 US utility patents between 2015 and 2025, placing Leviton Manufacturing Co., Inc. at rank #1,823 across all assignees tracked by PlainPatent. This portfolio spans 51 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.9 claims per patent with primary concentration in H05B (ELECTRIC HEATING; ELECTRIC LIGHT SOURCES NOT OTHERWISE PROVIDED FOR; CIRCUIT ARRANGEMENTS FOR ELECTRIC LIGHT SOURCES, IN GENERAL). As a US Corporation, Leviton Manufacturing Co., Inc. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Leviton sits between Airgain, Inc. (223 patents, rank #1,819) and Angel Co., Ltd. (221 patents, rank #1,827) - the closest US assignees by grant volume. The composite Innovation Score of 63.0/100 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 105 grants, compared with 117 in the 2015–2019 window, a -10% 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. Leviton Manufacturing Co., Inc.'s 20.9 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 51 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Leviton Manufacturing Co., Inc. against peers pursuing similar technology classes.

How to use this portfolio

Leviton's 222 grants land it in the top 2% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - Leviton ranks #1,823 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in H05B - see who else leads that technology area. H05B leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
