Portfolio overview

JSR Corporation has been granted 375 US utility patents between 2015 and 2025, placing JSR Corporation at rank #1,127 across all assignees tracked by PlainPatent. This portfolio spans 92 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.3 claims per patent with primary concentration in G03F (PHOTOMECHANICAL PRODUCTION OF TEXTURED OR PATTERNED SURFACES, e.g. FOR PRINTING, FOR PROCESSING OF SEMICONDUCTOR DEVICES; MATERIALS THEREFOR; ORIGINALS THEREFOR; APPARATUS SPECIALLY ADAPTED THEREFOR;). As a Foreign Corporation, JSR Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, JSR sits between Chiun Mai Communication Systems, Inc. (377 patents, rank #1,123) and MAKO Surgical Corp. (374 patents, rank #1,131) - the closest US assignees by grant volume. The composite Innovation Score of 60.4/100 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 129 grants, compared with 246 in the 2015–2019 window, a -48% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The Foreign 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. JSR Corporation's 14.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 92 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark JSR Corporation against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
