Claims and Allegations
Patent Infringement
Jazz asserts that Teva's generic product directly infringes on its patent claims. The core allegations include:
- Teva's manufacturing, marketing, and sale of the generic product constitute infringement.
- The infringing activity is willful, intending to compete with Jazz’s patented drug without license.
Declaratory Judgment
Jazz seeks a declaration that its patent is valid, enforceable, and infringed upon by Teva’s generic candidate, justifying injunctive relief.
Market Impact
Jazz argues that Teva’s alleged infringement could cause significant market and financial harm, including loss of exclusivity, market share, and profits.
