Portfolio overview

LINE Corporation has been granted 192 US utility patents between 2016 and 2024, placing LINE Corporation at rank #2,064 across all assignees tracked by PlainPatent. This portfolio spans 28 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.3 claims per patent with primary concentration in H04L (TRANSMISSION OF DIGITAL INFORMATION, e.g. TELEGRAPHIC COMMUNICATION). As a Foreign Corporation, LINE Corporation is one of the more focused assignees in the PatentsView dataset. By volume, LINE sits between Zeno Semiconductor, Inc. (193 patents, rank #2,060) and Sagemcom Broadband SAS (192 patents, rank #2,068) - the closest US assignees by grant volume. The composite Innovation Score of 50.6/100 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 120 grants, compared with 72 in the 2015–2019 window, a +67% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. LINE Corporation's 16.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 28 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark LINE Corporation 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.
