Portfolio overview

Johns Manville has been granted 383 US utility patents between 2015 and 2025, placing Johns Manville at rank #1,109 across all assignees tracked by PlainPatent. This portfolio spans 103 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.7 claims per patent with primary concentration in Y10T (TECHNICAL SUBJECTS COVERED BY FORMER US CLASSIFICATION). As a US Corporation, Johns Manville is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Johns sits between PPC Broadband, Inc. (386 patents, rank #1,105) and Aesculap Ag (380 patents, rank #1,113) - the closest US assignees by grant volume. The composite Innovation Score of 60.3/100 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 182 grants, compared with 201 in the 2015–2019 window, a -9% 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. Johns Manville's 17.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Johns Manville 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.
