DCT
SUBJECT
Patent
AUTHOR
Stark

Question(s) Presented

1. “Whether this Court may presume a district court considered and rejected issues and evidence presented, where the district court failed to address them and failed to provide sufficient detail by which it reached its ultimate determination.”

2. “Whether patent claims requiring measurement of a property are indefinite where the patent lacks reasonable certainty in sufficiently teaching an ordinary artisan how to make the measurement.”

3. “Whether a party can forfeit its ability to rely on a specific case on appeal, if not cited to the district court, where the underlying issue or principle had been raised.”
