FAQs
Q1: How does WO2019104134 differ from prior art compounds?
A1: The patent introduces a unique chemical scaffold with specific substitutions not disclosed in prior art, exhibiting improved pharmacological properties and therapeutic specificity.
Q2: Can existing drugs be challenged based on this patent?
A2: Only if the existing drugs use the patented chemical structure or methods claimed; the novelty and inventive step criteria would guide such legal challenges.
Q3: Is the patent likely to be enforceable globally?
A3: Enforcement depends on national filings and patent office examinations, but the international PCT application enables regional validations in key markets.
Q4: How do the claims protect against biosimilar development?
A4: While chemical entities are protected, biosimilar challenges are less relevant unless the invention involves biologics or related manufacturing processes.
Q5: What are the implications for generic manufacturers?
A5: They must design around the claims or wait for patent expiry, considering the patent's breadth and jurisdictional scope.
