Portfolio overview

Huang Chieh Metal Composite Material TECH. Co., Ltd. has been granted 5 US utility patents between 2018 and 2025, placing Huang Chieh Metal Composite Material TECH. Co., Ltd. at rank #47,409 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.8 claims per patent with primary concentration in H05K (PRINTED CIRCUITS; CASINGS OR CONSTRUCTIONAL DETAILS OF ELECTRIC APPARATUS; MANUFACTURE OF ASSEMBLAGES OF ELECTRICAL COMPONENTS). As a Foreign Corporation, Huang Chieh Metal Composite Material TECH. Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Huang sits between HT Materials Science (ip) Limited (5 patents, rank #47,405) and Huesker, Inc (5 patents, rank #47,413) - the closest US assignees by grant volume. The composite Innovation Score of 45.3/100 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 4 grants, compared with 1 in the 2015–2019 window, a +300% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Huang Chieh Metal Composite Material TECH. Co., Ltd.'s 9.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Huang Chieh Metal Composite Material TECH. Co., Ltd. against peers pursuing similar technology classes.
