Final answer:
UT's claim was upheld in the University of Texas v. KST Electric case.
Step-by-step explanation:
The court's assessment of UT's traditional trademark infringement claim in the case University of Texas v. KST Electric was that UT's claim was upheld. The court found that KST Electric had infringed upon UT's trademark rights and therefore ruled in favor of UT. This means that UT's claim was successful and KST Electric was found to be at fault.
