Portfolio overview

Watlow Electric Manufacturing Company has been granted 204 US utility patents between 2015 and 2025, placing Watlow Electric Manufacturing Company at rank #1,973 across all assignees tracked by PlainPatent. This portfolio spans 63 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.7 claims per patent with primary concentration in H05B (ELECTRIC HEATING; ELECTRIC LIGHT SOURCES NOT OTHERWISE PROVIDED FOR; CIRCUIT ARRANGEMENTS FOR ELECTRIC LIGHT SOURCES, IN GENERAL). As a US Corporation, Watlow Electric Manufacturing Company is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Watlow sits between Lummus Technology Llc (204 patents, rank #1,969) and Tridonic Gmbh & Co KG (203 patents, rank #1,977) - the closest US assignees by grant volume. The composite Innovation Score of 63.6/100 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 155 grants, compared with 49 in the 2015–2019 window, a +216% 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. Watlow Electric Manufacturing Company's 18.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 63 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Watlow Electric Manufacturing Company against peers pursuing similar technology classes.
