Portfolio overview

International Paper Company has been granted 186 US utility patents between 2015 and 2025, placing International Paper Company at rank #2,120 across all assignees tracked by PlainPatent. This portfolio spans 82 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.2 claims per patent with primary concentration in D21H (PULP COMPOSITIONS; PREPARATION THEREOF NOT COVERED BY SUBCLASSES D21C OR D21D; IMPREGNATING OR COATING OF PAPER; TREATMENT OF FINISHED PAPER NOT COVERED BY CLASS B31 OR SUBCLASS D21G; PAPER NOT OTHERW). As a US Corporation, International Paper Company is one of the broader-portfolio assignees in the PatentsView dataset. By volume, International sits between Université DE Bordeaux (187 patents, rank #2,116) and University Of Hong Kong (186 patents, rank #2,124) - the closest US assignees by grant volume. The composite Innovation Score of 57.7/100 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 81 grants, compared with 105 in the 2015–2019 window, a -23% 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. International Paper Company's 17.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 82 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark International Paper Company 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.
