Portfolio overview

WM Intellectual Property Holdings, L.l.c. has been granted 74 US utility patents between 2015 and 2025, placing WM Intellectual Property Holdings, L.l.c. at rank #4,745 across all assignees tracked by PlainPatent. This portfolio spans 42 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.0 claims per patent with primary concentration in Y02W (CLIMATE CHANGE MITIGATION TECHNOLOGIES RELATED TO WASTEWATER TREATMENT OR WASTE MANAGEMENT). As a US Corporation, WM Intellectual Property Holdings, L.l.c. is one of the more focused assignees in the PatentsView dataset. By volume, WM sits between Teijin Pharma Limited (74 patents, rank #4,741) and Aware, Inc. (73 patents, rank #4,749) - the closest US assignees by grant volume. The composite Innovation Score of 62.1/100 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 71 grants, compared with 3 in the 2015–2019 window, a +2267% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. WM Intellectual Property Holdings, L.l.c.'s 10.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 42 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark WM Intellectual Property Holdings, L.l.c. against peers pursuing similar technology classes.
