Across all tracked assignees
USPTO PatentsView assignee record - 8 granted patents across 16 technology areas, active 2022–2024. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: C08L (COMPOSITIONS OF MACROMOLECULAR COMPOUNDS).
The verdict
Hangzhou holds 8 US patents across 16 technology areas, rank #31,859 of 50,000 tracked assignees.
Hangzhou Xinglu Technologies Co., Ltd has been granted 8 US utility patents between 2022 and 2024, placing Hangzhou Xinglu Technologies Co., Ltd at rank #31,859 across all assignees tracked by PlainPatent. This portfolio spans 16 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.6 claims per patent with primary concentration in C08L (COMPOSITIONS OF MACROMOLECULAR COMPOUNDS). As a Foreign Corporation, Hangzhou Xinglu Technologies Co., Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Hangzhou sits between Haldor Advanced Technologies Ltd (8 patents, rank #31,855) and Harbor Innovations, Llc (8 patents, rank #31,863) - the closest US assignees by grant volume. The composite Innovation Score of 51.7/100 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 2022 through 2024, 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. Hangzhou Xinglu Technologies Co., Ltd's 16.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 16 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hangzhou Xinglu Technologies Co., Ltd against peers pursuing similar technology classes.

How to use this portfolio
Hangzhou's 8 grants land it in the top 11% 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.
