Across all tracked assignees
USPTO PatentsView assignee record - 5 granted patents across 4 technology areas, active 2022–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: G11C (STATIC STORES).
The verdict
Chengdu holds 5 US patents across 4 technology areas, rank #45,518 of 50,000 tracked assignees.
Chengdu Analog Circuit Technology Inc has been granted 5 US utility patents between 2022 and 2025, placing Chengdu Analog Circuit Technology Inc at rank #45,518 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.0 claims per patent with primary concentration in G11C (STATIC STORES). As a US Corporation, Chengdu Analog Circuit Technology Inc is one of the more focused assignees in the PatentsView dataset. By volume, Chengdu sits between CHEM Optics Inc (5 patents, rank #45,514) and Chertoff Group, Llc (5 patents, rank #45,522) - the closest US assignees by grant volume. The composite Innovation Score of 42.9/100 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. Historical data spans 2022 through 2025, with 5 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. The US 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. Chengdu Analog Circuit Technology Inc's 16.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Chengdu Analog Circuit Technology Inc against peers pursuing similar technology classes.

How to use this portfolio
Chengdu's 5 grants land it in the top 30% 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.
