Portfolio overview

Power Integrations, Inc. has been granted 384 US utility patents between 2015 and 2025, placing Power Integrations, Inc. at rank #1,108 across all assignees tracked by PlainPatent. This portfolio spans 36 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.5 claims per patent with primary concentration in H02M (APPARATUS FOR CONVERSION BETWEEN AC AND AC, BETWEEN AC AND DC, OR BETWEEN DC AND DC, AND FOR USE WITH MAINS OR SIMILAR POWER SUPPLY SYSTEMS; CONVERSION OF DC OR AC INPUT POWER INTO SURGE OUTPUT POWER;). As a US Corporation, Power Integrations, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Power sits between Infinera Corp. (386 patents, rank #1,104) and TE Connectivity Solutions Gmbh (381 patents, rank #1,112) - the closest US assignees by grant volume. The composite Innovation Score of 58.1/100 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 132 grants, compared with 252 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. Power Integrations, Inc.'s 20.5 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 36 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Power Integrations, Inc. against peers pursuing similar technology classes.

How to use this portfolio

Power's 384 grants land it in the top 5% 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 - Power ranks #1,108 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in H02M - see who else leads that technology area. H02M 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.
