Patent Timelines and Patent Term Extensions
- Average filing-to-grant time: 3-5 years.
- Patent term extensions are available in select jurisdictions up to 5 additional years, primarily in the US and Europe.
- The last key patent for first-line agents (e.g., rifampicin) is expiring in 2025–2027, opening pathways for generics.
Patent Challenges and Litigation
- Patent litigations mostly involve innovations around formulations and combination therapies.
- Patent challenges are common in India and China, where compulsory licensing mechanisms are more accessible.
- Patent expirations threaten market share for branded drugs, prompting firms to develop next-generation compounds.
How Are Regulatory Policies Affecting Market and Patent Strategies?
- Priority review pathways in the US and EU for new TB drugs aim to accelerate approval.
- WHO’s endorsement of shorter, all-oral regimens influences R&D focus areas.
- Patent term extensions and patent linkage are standard practices in Europe and the US, but less so in emerging markets.
- Compulsory licensing provisions in China and India can undermine patent exclusivity.
Strategic Insights for Stakeholders
- Innovators focus on NCEs with activity against MDR/XDR strains.
- Companies strengthen patent portfolios by combining method patents with composition patents.
- Public-private partnerships (PPPs) increasingly fund research, influencing patent filing intensities.
- Generics manufacturers leverage patent expirations to expand market share in high-burden countries.
Key Takeaways
- The market is expanding with steady growth projections, driven by TB prevalence and resistance.
- Patent activity centers on novel compounds and formulations; expiration of key patents will alter competitive landscapes.
- Patent filings peaked during 2017–2018, with major jurisdictions showing high activity.
- Patent challenges and potential patent expiry necessitate strategic innovation and patent diversification.
