Portfolio overview

Sigma Laboratories OF Arizona, Llc has been granted 7 US utility patents between 2015 and 2020, placing Sigma Laboratories OF Arizona, Llc at rank #37,415 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.9 claims per patent with primary concentration in C23C (COATING METALLIC MATERIAL; COATING MATERIAL WITH METALLIC MATERIAL; SURFACE TREATMENT OF METALLIC MATERIAL BY DIFFUSION INTO THE SURFACE, BY CHEMICAL CONVERSION OR SUBSTITUTION; COATING BY VACUUM EVAP). As a US Corporation, Sigma Laboratories OF Arizona, Llc is one of the more focused assignees in the PatentsView dataset. By volume, Sigma sits between Shinydocs Corporation (7 patents, rank #37,411) and Silmach (7 patents, rank #37,419) - the closest US assignees by grant volume. The composite Innovation Score of 35.5/100 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 grants, compared with 6 in the 2015–2019 window, a -83% 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. Sigma Laboratories OF Arizona, Llc's 20.9 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 20 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sigma Laboratories OF Arizona, Llc against peers pursuing similar technology classes.
