When Litigation Makes Sense
For IP owners facing infringement or needing to defend their market position, litigation protects valuable rights, deters future infringement, and maintains competitive advantage.
For accused infringers defending against infringement claims, strategic litigation defense protects your business operations while challenging invalid or overreaching assertions.
