Deep Dive into Patent Validity and Potential Patent Thickets
Validity Factors
- Novelty: Must differ from prior art. Old compounds or formulations cannot be claimed unless significantly modified.
- Inventive Step: Non-obviousness over existing patents and literature.
- Industrial Applicability: Demonstrated utility.
Potential Threats
- Obviousness over known compounds
- Prior art pre-dating patent filing
- Lack of sufficient disclosure
Patent Thickets
- Multiple overlapping patents can form dense protection layers, complicating generic entry or licensing.
