Scope of the Patent Claims
1. Overview of Claims
The '752 patent contains a series of claims broken into independent and dependent claims focused on:
- Compositions: Particularly, formulations involving cell populations combined with specific polymers or scaffolds.
- Methods: Techniques for preparing, administering, or modifying cell-based therapies.
- Uses: Specific medical applications, including immunomodulatory therapies and tissue regeneration.
2. Key Independent Claims
Although the full text must be examined for precise annotation, summarizing typical independent claims yields:
-
Claim 1: A composition comprising multipotent stromal cells (MSCs) or mesenchymal stem cells combined with a biodegradable scaffold material. The formulation aims to promote tissue regeneration.
-
Claim 2: A method of treating a disease or injury by administering the composition of Claim 1, where the disease includes autoimmune conditions, degenerative tissue damage, or inflammatory disorders.
-
Claim 3: A method for preparing the composition involving specific cultivation, genetic modification, or pre-conditioning steps to enhance cell viability or therapeutic function.
Each independent claim is supported by multiple dependent claims further specifying cell source, scaffold composition, dosage, or preparation methods.
3. Scope Analysis
