Novelty: The defendant challenged novelty, asserting similar formulations existed in prior art references.
Decision: The court found the claims sufficiently distinct.

Decision: The court affirmed the patent's enabling disclosure.

2. Infringement Analysis

• Literal Infringement: Court found Lilly’s drug formulations contain all elements of the patent claims.
• Doctrine of Equivalents: Also considered, with the court ruling claims were infringed under this doctrine.

3. Damages and Injunctive Relief
