Patent CA2599340: Scope, Claims, and Landscape

Last updated: February 20, 2026

What is the scope of patent CA2599340?

Patent CA2599340 covers a peptide-based pharmaceutical composition designed to treat autoimmune diseases. Filed by a major biopharmaceutical company, the patent claims to protect a specific peptide sequence and related formulations.

Key Components

• Application date: December 7, 2010.
• Publication date: September 5, 2012.
• Patent grant: February 26, 2013.
• Priority: based on a U.S. provisional application filed on December 7, 2009.

The patent claims encompass:

• The peptide sequence: a 15-amino acid peptide with specific modifications designed to enhance stability and bioavailability.
• Pharmaceutical formulations: including methods of administration, dosage forms, and combinations with adjuvants.
• Methods of use: particular indications such as multiple sclerosis (MS) and rheumatoid arthritis (RA).

Claims Overview

• Structural claims: Cover the specific peptide sequence with defined amino acid modifications.
• Method claims: Include methods for treating autoimmune diseases using the peptide.
• Formulation claims: Cover compositions containing the peptide in various delivery forms.

The claims are broad enough to prevent the synthesis of similar peptide sequences with minor modifications, with a focus on therapeutic application.
