1. Why Is It Necessary to Register Patents through an Intellectual Property Representative?

Unlike trademarks, patents require highly technical application dossiers and are subject to stringent protection standards.

A professional intellectual property representative organization will provide support in:

• Drafting patent specifications in accordance with international standards.
• Conducting prior art searches on a global scale.
• Determining appropriate protection strategies and optimizing the scope of protection.
