Portfolio overview
Signal Pharmaceuticals, LLC has been granted 78 US utility patents between 2015 and 2024, placing Signal Pharmaceuticals, LLC at rank #4,534 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.1 claims per patent with primary concentration in A61P (SPECIFIC THERAPEUTIC ACTIVITY OF CHEMICAL COMPOUNDS OR MEDICINAL PREPARATIONS). As a US Corporation, Signal Pharmaceuticals, LLC is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 38.2/100 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 15 grants, compared with 63 in the 2015–2019 window — a -76% 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. Signal Pharmaceuticals, LLC's 18.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Signal Pharmaceuticals, LLC against peers pursuing similar technology classes.
