Portfolio overview

Signify Holding B.v. has been granted 1,748 US utility patents between 2019 and 2025, placing Signify Holding B.v. at rank #237 across all assignees tracked by PlainPatent. This portfolio spans 155 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.1 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 Foreign Corporation, Signify Holding B.v. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Signify sits between Sumitomo Chemical Company, Limited (1,758 patents, rank #233) and Northwestern University (1,734 patents, rank #241) - the closest US assignees by grant volume. The composite Innovation Score of 63.5/100 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 1,481 grants, compared with 267 in the 2015–2019 window, a +455% 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. Signify Holding B.v.'s 13.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Signify Holding B.v. against peers pursuing similar technology classes.
