LIXIL CORPORATION

LIXIL CORPORATION has been granted 90 US utility patents between 2015 and 2025, placing LIXIL CORPORATION at rank #4,011 across all assignees tracked by PlainPatent. This portfolio spans 41 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.2 claims per patent with primary concentration in E03D (WATER-CLOSETS OR URINALS WITH FLUSHING DEVICES; FLUSHING VALVES THEREFOR). As a Foreign Corporation, LIXIL CORPORATION is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 45.1/100 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 57 grants, compared with 33 in the 2015–2019 window — a +73% 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. LIXIL CORPORATION's 6.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 41 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark LIXIL CORPORATION against peers pursuing similar technology classes.
