FAQs

  1. What are the main patent challenges for antineovascularisation agents in S01LA?
    The primary challenges involve patent litigations post-expiry of blockbuster biologics, patent thickets protecting complex biologics, and legal standards requiring clear non-obviousness for biologic patents.

  2. How does the patent landscape influence market competition?
    Strong patent portfolios delay biosimilar entry, allowing branded biologics to maintain pricing power. Conversely, expiry dates open opportunities for biosimilars, increasing competition.

  3. Are biosimilars impacting the market for S01LA agents?
    Yes. As patents expire (e.g., Lucentis in 2022), biosimilars are entering markets, offering lower-cost alternatives and pressuring branded agents.

  4. What innovations are expected in future S01LA agents?
    Expect dual-mechanism biologics, sustained-release delivery systems, gene therapies, and combination therapies aimed at reducing treatment frequency and improving outcomes.

  5. What role do regulatory policies play in patent strategies for S01LA agents?
    Regulatory pathways that favor accelerated approval of biosimilars and combination therapies incentivize innovation and influence the timing of patent filings.
