IP Litigation & Enforcement

Take Action to Protect Your Intellectual Property

When your registered IP is under threat—whether it’s a patent, trademark, design, or utility model —you have the right to demand that infringers stop and compensate for damages. A well-crafted cease-and-desist letter is often the first step.


But success requires more than sending a notice:
Patents: Precise claim interpretation and element-by-element comparison
Trademarks & Designs: Legal standards of similarity and likelihood of confusion

  • Patents: Precise claim interpretation and element-by-element comparison
  • Trademarks & Designs: Legal standards of similarity and likelihood of confusion

  • Infringement Injunctions and
    Damage Claims
