The verdict
Guangdong holds 6 US patents across 10 technology areas, rank #40,449 of 50,000 tracked assignees.
Guangdong Fenghua Advanced Technology Holding Co., Ltd. has been granted 6 US utility patents between 2021 and 2025, placing Guangdong Fenghua Advanced Technology Holding Co., Ltd. at rank #40,449 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.7 claims per patent with primary concentration in C04B (LIME, MAGNESIA; SLAG; CEMENTS; COMPOSITIONS THEREOF, e.g. MORTARS, CONCRETE OR LIKE BUILDING MATERIALS; ARTIFICIAL STONE ; CERAMICS ; REFRACTORIES; TREATMENT OF NATURAL STONE). As a Foreign Corporation, Guangdong Fenghua Advanced Technology Holding Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Guangdong sits between GTL Company (6 patents, rank #40,445) and Guangdong Newdermo Biotech Co., Ltd (6 patents, rank #40,453) - the closest US assignees by grant volume. The composite Innovation Score of 44.9/100 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 2021 through 2025, with 6 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. Guangdong Fenghua Advanced Technology Holding Co., Ltd.'s 11.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Guangdong Fenghua Advanced Technology Holding Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Guangdong's 6 grants land it in the top 24% 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.
