Deep Dive: Patent Disputes in Pharmaceutical Industry
What Are the Typical Grounds for Patent Invalidity?
- Prior art evidence: Earlier publications or patents that predate the contested patent.
- Obviousness: Combining existing knowledge in a manner that would be obvious to skilled professionals.
- Insufficient disclosure: Patent application must clearly describe the invention.
How Do Courts Assess Patent Infringement?
- Claim construction: Courts interpret patent claims for scope and meaning.
- Comparison of accused products: Analyzing whether accused products meet the claim limitations.
- Expert testimony: Often pivotal in establishing infringement or invalidity.
