 Other common attribute values are defined in the `_attributes/common-attributes.adoc` file. Where possible, generalize references to those values by using the common attributes. For example, use `{cluster-manager-first}` to refer to Red Hat OpenShift Cluster Manager.

+== Third-party vendor product names
+
+Red Hat integrates with many third-party vendor products. For certain integrated products, third-party vendor staff might have access to certain Red Hat resources and be contactable within Red Hat. On other occasions, common open-source products might be widely used across IT infrastructure providers, so Red Hat might not have direct contacts to organizations that own these products.
+
+Depending on the third-party vendor's requirements, you might need to add a registered trademark symbol to all of the vendor's product names or only on the first occurence of referencing the product name in an assembly, a module, or a document.  
+
+Choose any of the following sources for clarification on using the symbol for a specific third-party vendor product name:
+
+* Visit the third-party vendor's website and contact them directly.
+* Contact internal Red Hat product teams or integrated third-party vendor teams.
+* Contact the Red Hat Legal team. Only consider this option when the other two options did not provide clear context for your query.
+
+[IMPORTANT]
+====
+Do not use Asciidoctor character replacement substitutions, which rely on a Unicode code point such as _&#174;_, to set the registered symbol in an Asciidoc file. Instead use _(R)_ beside the product name. For example, `IBM(R) LinuxONE`.
+
+Do not apply any superscript, such as `(R)`, or subscript formatting to module or assembly headings.
