Zhuhai Tessan Power Technology Co., Ltd. has been granted 8 US utility patents between 2023 and 2025, placing Zhuhai Tessan Power Technology Co., Ltd. at rank #33,992 across all assignees tracked by PlainPatent. This portfolio spans 0 distinct Cooperative Patent Classification (CPC) subclasses, averaging 1.0 claims per patent. As a Foreign Corporation, Zhuhai Tessan Power Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Zhuhai sits between Zhejiang Runva Mechanical & Electrical Co., Ltd. (8 patents, rank #33,988) and Zomedica Biotechnologies Llc (8 patents, rank #33,996) - the closest US assignees by grant volume. The composite Innovation Score of 28.2/100 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 2023 through 2025, with 8 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Zhuhai Tessan Power Technology Co., Ltd.'s 1.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 0 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Zhuhai Tessan Power Technology Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Zhuhai's 8 grants land it in the top 74% 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.
