The composite Innovation Score of 29.2/100 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 2021 through 2025, with 11 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. Zhongshan Haoqi Electrical Appliance 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 Zhongshan Haoqi Electrical Appliance Co., Ltd against peers pursuing similar technology classes.

How to use this portfolio
Zhongshan's 11 grants land it in the top 70% 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.
