Portfolio overview

Purdue Pharma L.p. has been granted 365 US utility patents between 2015 and 2025, placing Purdue Pharma L.p. at rank #1,167 across all assignees tracked by PlainPatent. This portfolio spans 29 distinct Cooperative Patent Classification (CPC) subclasses, averaging 23.4 claims per patent with primary concentration in A61P (SPECIFIC THERAPEUTIC ACTIVITY OF CHEMICAL COMPOUNDS OR MEDICINAL PREPARATIONS). As a US Corporation, Purdue Pharma L.p. is one of the more focused assignees in the PatentsView dataset. By volume, Purdue sits between City Of Hope (366 patents, rank #1,163) and Fenwal, Inc. (363 patents, rank #1,171) - the closest US assignees by grant volume. The composite Innovation Score of 57.5/100 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 68 grants, compared with 297 in the 2015–2019 window, a -77% 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. Purdue Pharma L.p.'s 23.4 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 29 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Purdue Pharma L.p. 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.
