The verdict
Spectrum holds 446 US patents across 2 technology areas, rank #988 of 50,000 tracked assignees.
Spectrum Diversified Designs, Llc has been granted 446 US utility patents between 2015 and 2024, placing Spectrum Diversified Designs, Llc at rank #988 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 1.1 claims per patent with primary concentration in A47K (SANITARY EQUIPMENT NOT OTHERWISE PROVIDED FOR ; TOILET ACCESSORIES). As a US Corporation, Spectrum Diversified Designs, Llc is one of the more focused assignees in the PatentsView dataset. By volume, Spectrum sits between Yanmar Holdings Co., Ltd. (448 patents, rank #984) and University OF Maryland, College PARK (444 patents, rank #992) - the closest US assignees by grant volume. The composite Innovation Score of 29.4/100 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 184 grants, compared with 262 in the 2015–2019 window, a -30% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Spectrum Diversified Designs, Llc's 1.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 2 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Spectrum Diversified Designs, Llc against peers pursuing similar technology classes.

How to use this portfolio
Spectrum's 446 grants land it in the top 69% by Innovation Score, but volume alone doesn't tell you where the strength sits.
Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
