+## Trademarked terms
+
+You can use third-party trademarked terms (including those of competitors) when necessary to describe their goods and services accurately, or to prevent marketplace confusion between Red Hat and third parties.. 
+
+When using trademarks:
+- Avoid using them as attention-getting devices.
+- Ensure their usage does not mislead users.
+- Use them only to objectively compare relevant and verifiable goods or services.
+- Do not discredit or denigrate a competitor's trademarks, trade names or other distinguishing signs.
+- Do not take unfair advantage of a competitor's trademark.
+- Do not present goods or services as imitations or replicas of trademarked products.
+- Limit trademark usage to body text rather than headlines, titles, or graphics.
+- Never use a third party's logo without explicit permission.

Our platform is 20% faster and costs half as much as their legacy junk. | In independent benchmarks, Red Hat OpenShift demonstrated 20% faster deployment times compared to VMware vSphere. Our solution offers a verifiable cost-efficiency advantage for enterprise-scale workloads.|
