Some information may be available in the NIST Patents Database that can be accessed through https://www.nist.gov/tpo/patents

Other useful information describing the "Quality" of the document:

This standard specifies hash algorithms that can be used to generate digests of messages. The digests are used to detect whether messages have been changed since the digests were generated. This NIST document has been produced by Computer Security Division's (CSD) Security Technology Group of NIST has a subgroup that deals specifically with Cryptographic Technology Standards and Guidance (CTSG). CTSG is involved in the development, maintenance, and promotion of a number of standards and guidance that cover a wide range of cryptographic technology. NIST has long term technical experience in dealing with cryptographic matters. The document has been publicly and internally reviewed before publication.

The degree of stability or maturity of the document:

Published in August 2015. This Standard supersedes FIPS 180-3.

Relationship with other existing or emerging documents:

None
