Portfolio overview

Ching FENG HOME Fashions Co., Ltd. has been granted 30 US utility patents between 2015 and 2025, placing Ching FENG HOME Fashions Co., Ltd. at rank #10,275 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.6 claims per patent with primary concentration in E06B (FIXED OR MOVABLE CLOSURES FOR OPENINGS IN BUILDINGS, VEHICLES, FENCES OR LIKE ENCLOSURES IN GENERAL, e.g. DOORS, WINDOWS, BLINDS, GATES). As a Foreign Corporation, Ching FENG HOME Fashions Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Ching sits between Brose Fahrzeugteile Gmbh & Co. KG, Wuerzburg (30 patents, rank #10,271) and CUB Elecparts Inc. (30 patents, rank #10,279) - the closest US assignees by grant volume. The composite Innovation Score of 36.9/100 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. Between 2020 and 2025 the company received 16 grants, compared with 14 in the 2015–2019 window, a +14% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Ching FENG HOME Fashions Co., Ltd.'s 6.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ching FENG HOME Fashions Co., Ltd. against peers pursuing similar technology classes.
