Portfolio overview

Taiwan Hopax Chemicals Mfg. Co., Ltd. has been granted 14 US utility patents between 2015 and 2024, placing Taiwan Hopax Chemicals Mfg. Co., Ltd. at rank #20,523 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 4.6 claims per patent with primary concentration in B42D (BOOKS; BOOK COVERS; LOOSE LEAVES; PRINTED MATTER CHARACTERISED BY IDENTIFICATION OR SECURITY FEATURES; PRINTED MATTER OF SPECIAL FORMAT OR STYLE NOT OTHERWISE PROVIDED FOR; DEVICES FOR USE THEREWITH A). As a Foreign Corporation, Taiwan Hopax Chemicals Mfg. Co., Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 24.3/100 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 5 grants, compared with 9 in the 2015–2019 window — a -44% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Taiwan Hopax Chemicals Mfg. Co., Ltd.'s 4.6 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 Taiwan Hopax Chemicals Mfg. Co., Ltd. against peers pursuing similar technology classes.
