Portfolio overview

Wolfspeed, Inc. has been granted 201 US utility patents between 2021 and 2025, placing Wolfspeed, Inc. at rank #1,997 across all assignees tracked by PlainPatent. This portfolio spans 35 distinct Cooperative Patent Classification (CPC) subclasses, averaging 24.5 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a US Corporation, Wolfspeed, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Wolfspeed sits between Renesas Electronics America Inc. (201 patents, rank #1,993) and Linear Technology Holding Llc (200 patents, rank #2,001) - the closest US assignees by grant volume. The composite Innovation Score of 74.0/100 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. Historical data spans 2021 through 2025, with 201 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. Wolfspeed, Inc.'s 24.5 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 35 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Wolfspeed, Inc. against peers pursuing similar technology classes.

How to use this portfolio

Wolfspeed's 201 grants land it in the top 0.1% 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 - Wolfspeed ranks #1,997 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in H01L - see who else leads that technology area. H01L 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.
