Notice is hereby given that, on April 25, 2024,
pursuant to section 6(a) of the National Cooperative
Research and Production Act of 1993, 15 U.S.C. 4301 et seq.
(“the Act”), Alliance for OpenUSD Series LLC (“AOUSD”) has
filed written notifications simultaneously with the
Attorney General and the Federal Trade Commission
disclosing additions or changes to its standards
development activities. The notifications were filed for
the purpose of extending the Act’s provisions limiting the
recovery of antitrust plaintiffs to actual damages under
specified circumstances.

Specifically, AOUSD has formed

two additional Working Groups ("WGs") in March 2024: a
Materials WG and a Geometry WG. The Materials WG will
standardize the description of materials in OpenUSD. Its
initial focus and first deliverable will be the USD
Material Interchange Specification, which will comprise a
set of patterns and BSDF nodes comprising the MaterialX
standard libraries. The Geometry WG will define and evolve
the strategy for the description of 3D geometry in OpenUSD.
Its first deliverable will be the USD Transformable 3D
Geometry Specification that will describe the surfaces and
volume representations, spatial transformations, rules of

determining primary visibility, and other properties
required for imaging those representations.
On October 30, 2023, AOUSD filed its original
notification pursuant to section 6(a) of the Act.

The

Department of Justice published a notice in the Federal
Register pursuant to section 6(b) of the Act on December
