The verdict
SPEX holds 10 US patents across 10 technology areas, rank #27,381 of 50,000 tracked assignees.
SPEX Sampleprep, Llc has been granted 10 US utility patents between 2017 and 2025, placing SPEX Sampleprep, Llc at rank #27,381 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.4 claims per patent with primary concentration in B02C (CRUSHING, PULVERISING, OR DISINTEGRATING IN GENERAL; MILLING GRAIN). As a US Corporation, SPEX Sampleprep, Llc is one of the more focused assignees in the PatentsView dataset. By volume, SPEX sits between Soprema (10 patents, rank #27,377) and SRF Limited (10 patents, rank #27,385) - the closest US assignees by grant volume. The composite Innovation Score of 46.6/100 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 6 grants, compared with 4 in the 2015–2019 window, a +50% 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. SPEX Sampleprep, Llc's 17.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SPEX Sampleprep, Llc against peers pursuing similar technology classes.

How to use this portfolio
SPEX's 10 grants land it in the top 20% 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.
