Portfolio overview
Taimei Chemicals Co., Ltd. has been granted 16 US utility patents between 2016 and 2024, placing Taimei Chemicals Co., Ltd. at rank #18,159 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.8 claims per patent with primary concentration in B24D (TOOLS FOR GRINDING, BUFFING OR SHARPENING). As a Foreign Corporation, Taimei Chemicals Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Taimei sits between Syndicate Sales, Inc. (16 patents, rank #18,155) and TE Connectivity Brasil Industria De Eletronicos Ltda. (16 patents, rank #18,163) - the closest US assignees by grant volume. The composite Innovation Score of 29.0/100 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. Between 2020 and 2025 the company received 5 grants, compared with 11 in the 2015–2019 window, a -55% 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. Taimei Chemicals Co., Ltd.'s 6.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Taimei Chemicals Co., Ltd. against peers pursuing similar technology classes.
