FAQs
Q1: What are common defenses in patent infringement cases like Patheon v. Apotex?
A: Defendants often argue patent invalidity based on prior art or obviousness, non-infringement due to differences in formulation or process, or that patents are indefinite or not enabled.
Q2: How can patent holders strengthen their enforcement strategies?
A: By filing broad yet defensible claims, conducting thorough prior art searches, and actively monitoring market activities for potential infringements.
Q3: What factors influence whether a case settles or proceeds to trial?
A: Patent strength, litigation costs, potential damages, likelihood of invalidity, and strategic business considerations.
Q4: Are patent disputes in softgel formulations typical in the pharmaceutical industry?
A: Yes, formulation patents are common, especially for sustained-release, bioavailability, or stability improvements, making this a frequent litigation area.
Q5: What impact do these litigations have on drug prices and availability?
A: They can delay generic entry, maintain higher prices temporarily, or lead to licensing agreements that facilitate market competition.
