Portfolio overview

TEIKOKU SEIYAKU CO., LTD. has been granted 45 US utility patents between 2015 and 2025, placing TEIKOKU SEIYAKU CO., LTD. at rank #7,339 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.7 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a Foreign Corporation, TEIKOKU SEIYAKU CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 31.2/100 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 12 grants, compared with 33 in the 2015–2019 window — a -64% 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. TEIKOKU SEIYAKU CO., LTD.'s 6.7 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 TEIKOKU SEIYAKU CO., LTD. against peers pursuing similar technology classes.
