Portfolio overview

Lummus Technology Llc has been granted 204 US utility patents between 2015 and 2025, placing Lummus Technology Llc at rank #1,969 across all assignees tracked by PlainPatent. This portfolio spans 45 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.2 claims per patent with primary concentration in B01J (CHEMICAL OR PHYSICAL PROCESSES, e.g. CATALYSIS OR COLLOID CHEMISTRY; THEIR RELEVANT APPARATUS). As a US Corporation, Lummus Technology Llc is one of the more focused assignees in the PatentsView dataset. By volume, Lummus sits between Entropic Communications, Llc (204 patents, rank #1,965) and Watlow Electric Manufacturing Company (204 patents, rank #1,973) - the closest US assignees by grant volume. The composite Innovation Score of 57.3/100 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 123 grants, compared with 81 in the 2015–2019 window, a +52% 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. Lummus Technology Llc's 16.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 45 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Lummus Technology Llc against peers pursuing similar technology classes.
