Portfolio overview

Quest Diagnostics Investments Llc has been granted 329 US utility patents between 2015 and 2025, placing Quest Diagnostics Investments Llc at rank #1,287 across all assignees tracked by PlainPatent. This portfolio spans 31 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.3 claims per patent with primary concentration in G01N (INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES). As a US Corporation, Quest Diagnostics Investments Llc is one of the more focused assignees in the PatentsView dataset. By volume, Quest sits between Thyssenkrupp Presta Aktiengesellschaft (330 patents, rank #1,283) and Alpha And Omega Semiconductor, Ltd. (327 patents, rank #1,291) - the closest US assignees by grant volume. The composite Innovation Score of 54.7/100 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 188 grants, compared with 141 in the 2015–2019 window, a +33% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Quest Diagnostics Investments Llc's 15.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 31 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Quest Diagnostics Investments Llc against peers pursuing similar technology classes.

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.
