Portfolio overview
Chemlink Laboratories, Llc has been granted 5 US utility patents between 2015 and 2021, placing Chemlink Laboratories, Llc at rank #45,817 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.8 claims per patent with primary concentration in C11D (DETERGENT COMPOSITIONS; USE OF SINGLE SUBSTANCES AS DETERGENTS; SOAP OR SOAP-MAKING; RESIN SOAPS; RECOVERY OF GLYCEROL). As a US Corporation, Chemlink Laboratories, Llc is one of the more focused assignees in the PatentsView dataset. By volume, Chemlink sits between Charles River Laboratories International, Inc. (5 patents, rank #45,813) and Chengli Li (5 patents, rank #45,821) - the closest US assignees by grant volume. The composite Innovation Score of 23.6/100 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 1 grants, compared with 4 in the 2015–2019 window, a -75% 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. Chemlink Laboratories, Llc's 18.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Chemlink Laboratories, Llc against peers pursuing similar technology classes.
