Portfolio overview

Chaei Hsin Enterprise Co., Ltd. has been granted 10 US utility patents between 2016 and 2024, placing Chaei Hsin Enterprise Co., Ltd. at rank #26,029 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.1 claims per patent with primary concentration in B29C (SHAPING OR JOINING OF PLASTICS; SHAPING OF MATERIAL IN A PLASTIC STATE, NOT OTHERWISE PROVIDED FOR; AFTER-TREATMENT OF THE SHAPED PRODUCTS, e.g. REPAIRING). As a Foreign Corporation, Chaei Hsin Enterprise Co., Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 38.2/100 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 6 grants, compared with 4 in the 2015–2019 window — a +50% 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. Chaei Hsin Enterprise Co., Ltd.'s 10.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 18 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Chaei Hsin Enterprise Co., Ltd. against peers pursuing similar technology classes.
