Portfolio overview

Hesai Technology Co., Ltd. has been granted 42 US utility patents between 2021 and 2025, placing Hesai Technology Co., Ltd. at #7,707 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.9 claims per patent with primary concentration in G01S (RADIO DIRECTION-FINDING; RADIO NAVIGATION; DETERMINING DISTANCE OR VELOCITY BY USE OF RADIO WAVES; LOCATING OR PRESENCE-DETECTING BY USE OF THE REFLECTION OR RERADIATION OF RADIO WAVES; ANALOGOUS ARRA). As a Foreign Corporation, Hesai Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Hesai sits between HSIO Technologies, Llc (42 patents, rank #7,705) and Inpex Corporation (42 patents, rank #7,713) - the closest US assignees by grant volume. The composite Innovation Score of 54.5/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Historical data spans 2021 through 2025, with 42 total grants over that period. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Hesai Technology Co., Ltd.'s 13.9 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 14 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.

How to use this portfolio

Hesai's 42 grants land it in the top 8% 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 - Hesai ranks #7,707 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in G01S - see who else leads that technology area. G01S 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.
