Portfolio overview
Bluewillow Biologics, Inc. has been granted 5 US utility patents between 2021 and 2024, placing Bluewillow Biologics, Inc. at rank #45,169 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.4 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a US Corporation, Bluewillow Biologics, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Bluewillow sits between Bluedop Medical, Ltd. (5 patents, rank #45,165) and BMSI, Inc. (5 patents, rank #45,173) - the closest US assignees by grant volume. The composite Innovation Score of 34.9/100 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. Historical data spans 2021 through 2024, with 5 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Bluewillow Biologics, Inc.'s 19.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Bluewillow Biologics, Inc. against peers pursuing similar technology classes.
