Portfolio overview

Hesai Photonics Technology Co., Ltd. has been granted 13 US utility patents between 2019 and 2021, placing Hesai Photonics Technology Co., Ltd. at rank #21,231 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 21.1 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 Photonics Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 27.9/100 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. Between 2020 and 2025 the company received 6 grants, compared with 7 in the 2015–2019 window, a -14% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The Foreign 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. Hesai Photonics Technology Co., Ltd.'s 21.1 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hesai Photonics Technology Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio

Hesai's 13 grants land it in the top 75% 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 #21,231 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.
