This page is an IP policy overview. The active policy layer is maintained at Sigma Stratum Intellectual Property, Licensing, and Certification Policy.
The Sigma Runtime Standard is an open public specification. Independent implementation of public SRS/SRIP normative requirements does not by itself require a Sigma commercial runtime license.
Independent ideas, methods, algorithms, and systems remain independent when they are developed without copying protected Sigma expression or proprietary Sigma Runtime assets.
This policy protects Sigma-authored expression, attribution requirements, protected research materials, Sigma marks, official certification, proprietary runtime assets, commercial use of CC BY-NC materials, and operated Sigma Runtime product surfaces.
The main policy is:
This IP policy overview should be read with:
Contributors retain copyright to their individual submissions.
By submitting content to the Sigma Runtime Standard or the SRIP process, each contributor grants Sigma Stratum permission to publish, adapt, distribute, and incorporate the contribution for standardization, governance, documentation, and public specification maintenance purposes.
This contribution permission applies to the standardization context. It does not transfer ownership of unrelated external projects, independent implementations, or independently developed systems.
Independent implementation of public SRS/SRIP normative requirements is permitted under the applicable public specification terms.
No Sigma commercial runtime license is required solely because an implementation follows public SRS/SRIP normative requirements.
This safe harbor is about implementing public requirements. Product code, private modules, ALICE internals, runtime telemetry, private datasets, product UX, production memory/control mechanisms, deployment topology, support, SLA, certification badges, and Sigma marks follow their own policies or written terms.
The following use their own policies or written terms:
∿, certification badges, and official compatibility language;Contributors are responsible for ensuring that submitted material is original, compatible with the public specification process, and free of third-party licensing conflicts.
Do not submit copyrighted text, diagrams, code, datasets, or proprietary implementation details without appropriate rights and approval.
The ∿ symbol, Sigma Stratum, Sigma Runtime, official certification badges, and official compatibility language are governed marks and certification surfaces.
Descriptive references to SRS/SRIP are permitted for citation, attribution, discussion, and truthful self-declaration under the applicable public rules.
Use of Sigma marks as product identity, service identity, certification identity, endorsement, or official compatibility claim requires written permission.
Material changes to this policy should be versioned, reviewable, and coordinated with the main IP, licensing, and certification policy.
