The verdict
Dongguan holds 7 US patents across 7 technology areas, rank #34,971 of 50,000 tracked assignees.
Dongguan CITY Wonderful Ceramics Industrial PARK Co., Ltd. has been granted 7 US utility patents between 2023 and 2025, placing Dongguan CITY Wonderful Ceramics Industrial PARK Co., Ltd. at rank #34,971 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.4 claims per patent with primary concentration in C03C (CHEMICAL COMPOSITION OF GLASSES, GLAZES OR VITREOUS ENAMELS; SURFACE TREATMENT OF GLASS; SURFACE TREATMENT OF FIBRES OR FILAMENTS MADE FROM GLASS, MINERALS OR SLAGS; JOINING GLASS TO GLASS OR OTHER MA). As a Foreign Corporation, Dongguan CITY Wonderful Ceramics Industrial PARK Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Dongguan sits between DNE, Llc (7 patents, rank #34,967) and Dorst Technologies Gmbh & Co. KG (7 patents, rank #34,975) - the closest US assignees by grant volume. The composite Innovation Score of 41.0/100 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 2023 through 2025, with 7 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. Dongguan CITY Wonderful Ceramics Industrial PARK Co., Ltd.'s 7.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Dongguan CITY Wonderful Ceramics Industrial PARK Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Dongguan's 7 grants land it in the top 34% 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.
