Leo Patent Law Office

Established in August 2023, we humbly stand as a patent law firm deeply dedicated to providing quality services within the realm of patent law.

Our Unique Approach: What sets us apart is our distinctive approach to patent representation.

We do:

• Filing and prosecuting directly before the USPTO including Examiner Interview from Europe
• Pre-Appeal Brief and Appeal before the USPTO
• Assisting in PTAB AIA-trials before the USPTO
• Filing and prosecuting before the EPO
• Opposition and appeal proceedings before the EPO
• Patent litigation before the UPC
