Portfolio overview

Alexion Pharmaceuticals, Inc. has been granted 146 US utility patents between 2015 and 2025, placing Alexion Pharmaceuticals, Inc. at rank #2,654 across all assignees tracked by PlainPatent. This portfolio spans 19 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.4 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a US Corporation, Alexion Pharmaceuticals, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Alexion sits between Unison Industries, Llc (147 patents, rank #2,650) and Herman Miller, Inc. (146 patents, rank #2,658) - the closest US assignees by grant volume. The composite Innovation Score of 51.1/100 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 84 grants, compared with 62 in the 2015–2019 window, a +35% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Alexion Pharmaceuticals, Inc.'s 17.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 19 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Alexion Pharmaceuticals, Inc. 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.
