USPTO PatentsView assignee record - 93 granted patents across 5 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: F21S (NON-PORTABLE LIGHTING DEVICES; SYSTEMS THEREOF; VEHICLE LIGHTING DEVICES SPECIALLY ADAPTED FOR VEHICLE EXTERIORS).
The verdict
Sonar holds 93 US patents across 5 technology areas, rank #3,894 of 50,000 tracked assignees.
Sonar AUTO Parts Co., Ltd. has been granted 93 US utility patents between 2015 and 2025, placing Sonar AUTO Parts Co., Ltd. at rank #3,894 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 1.6 claims per patent with primary concentration in F21S (NON-PORTABLE LIGHTING DEVICES; SYSTEMS THEREOF; VEHICLE LIGHTING DEVICES SPECIALLY ADAPTED FOR VEHICLE EXTERIORS). As a Foreign Corporation, Sonar AUTO Parts Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Sonar sits between Labrador Diagnostics Llc (93 patents, rank #3,890) and Sloan Kettering Institute For Cancer Research (93 patents, rank #3,898) - the closest US assignees by grant volume. The composite Innovation Score of 36.9/100 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 80 grants, compared with 13 in the 2015–2019 window, a +515% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Sonar AUTO Parts Co., Ltd.'s 1.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sonar AUTO Parts Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Sonar's 93 grants land it in the top 45% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
