Portfolio overview

Daiichi Sankyo Company, Limited has been granted 302 US utility patents between 2015 and 2025, placing Daiichi Sankyo Company, Limited at rank #1,391 across all assignees tracked by PlainPatent. This portfolio spans 31 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.8 claims per patent with primary concentration in A61P (SPECIFIC THERAPEUTIC ACTIVITY OF CHEMICAL COMPOUNDS OR MEDICINAL PREPARATIONS). As a Foreign Corporation, Daiichi Sankyo Company, Limited is one of the more focused assignees in the PatentsView dataset. By volume, Daiichi sits between Verint Americas Inc. (303 patents, rank #1,387) and Neoperl Gmbh (302 patents, rank #1,395) - the closest US assignees by grant volume. The composite Innovation Score of 56.1/100 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 137 grants, compared with 165 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 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. Daiichi Sankyo Company, Limited's 18.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 31 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Daiichi Sankyo Company, Limited against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
