Declaratory judgement of invalidation
When is Declaratory Judgment of Invalidation Used?
A declaratory judgment of invalidation is a proactive legal strategy where a party (usually the accused infringer) files a lawsuit in federal court seeking a ruling that a patent is invalid. This action allows the potential defendant to gain control over the forum and timing of the dispute while attempting to neutralize a patent asserted against them.
A declaratory judgment of invalidity is commonly sought in these scenarios:
Preemptive Strike: The accused infringer has been threatened with patent litigation (e.g., cease-and-desist letter or licensing demands).
Clear Invalidity Arguments: Strong grounds exist to demonstrate that the patent is invalid (e.g., prior art, lack of enablement, or indefiniteness).
Uncertainty or Business Impact: The presence of a patent creates a risk of future lawsuits, disrupts business operations, or deters customers.
