| Claim Number |
Summary |
Critical Analysis |
| 1 |
A composition comprising a monoclonal antibody characterized by [specific features], for use in treating [disease]. |
Broad, covering any antibody with similar features; potential vulnerability to prior art if general antibody techniques are well-known. |
| 10 |
A method for delivering [compound] to [target tissue], involving [specific steps or devices]. |
Technologically specific, offering clearer infringement pathways but potentially limited in scope. |
Note: The claims emphasize both composition and method facets, reflecting a strategy to secure broad coverage.
2.3. Claim Validity Challenges
- Novelty: Potential overlaps with prior art such as [insert references], which disclose monoclonal antibodies with similar binding domains as early as [year].
- Obviousness: The use of standard antibody engineering techniques may render broad claims obvious unless the '397 patent employs an unexpected modification.
- Written description and enablement: The patent adequately discloses the claimed antibodies and methods, complying with 35 U.S.C. § 112, but claims' breadth may invite validity challenges.
2.4. Strategic Claim Drafting Considerations
- Broad claims maximize market scope but are more susceptible to invalidation.
- Narrow, dependent claims serve as fallback options and clarify specific embodiments.
- Cross-referencing to prior art in the specification may infer limitations to reinforce validity.
