Portfolio overview

Tosoh SMD, Inc. has been granted 11 US utility patents between 2015 and 2025, placing Tosoh SMD, Inc. at rank #25,359 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.1 claims per patent with primary concentration in C23C (COATING METALLIC MATERIAL; COATING MATERIAL WITH METALLIC MATERIAL; SURFACE TREATMENT OF METALLIC MATERIAL BY DIFFUSION INTO THE SURFACE, BY CHEMICAL CONVERSION OR SUBSTITUTION; COATING BY VACUUM EVAP). As a US Corporation, Tosoh SMD, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Tosoh sits between Tianhua Institute OF Chemical Machinery AND Automation Co., Ltd (11 patents, rank #25,355) and Tribu Nv (11 patents, rank #25,363) - the closest US assignees by grant volume. The composite Innovation Score of 27.4/100 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 6 in the 2015–2019 window, a -17% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US 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. Tosoh SMD, Inc.'s 10.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Tosoh SMD, Inc. against peers pursuing similar technology classes.
