Hangzhou Sicco Art-technology Co., Ltd has been granted 6 US utility patents between 2016 and 2017, placing Hangzhou Sicco Art-technology Co., Ltd at rank #40,602 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, Hangzhou Sicco Art-technology Co., Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Hangzhou sits between Hangzhou LHD Institute OF NEW Energy, Llc (6 patents, rank #40,598) and Hanvon UGEE Technology Co., Ltd. (6 patents, rank #40,606) - the closest US assignees by grant volume. The composite Innovation Score of 7.3/100 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 0 grants, compared with 6 in the 2015–2019 window, a -100% 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. Hangzhou Sicco Art-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 Hangzhou Sicco Art-technology Co., Ltd against peers pursuing similar technology classes.

How to use this portfolio
Hangzhou's 6 grants land it in the top 100% 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.
