Substantiated obviousness arguments
Delivered prior art directly supporting invalidity positions aligned with opposition strategy.
The Challenge
Navigating complex biotech prior art search
A global biotechnology company developing cell-based therapies faced a critical need to assess the validity of a European patent during opposition proceedings. The matter required deep technical analysis in a highly specialized area involving human clinical trials, ischemia treatment, angiogenesis, and bone marrow-derived cell therapies.
The internal IP team required a partner capable of navigating complex biomedical literature, clinical trial databases, and global patent filings, while responding quickly to evolving questions from the European Patent Office
The Solution
A Multi-Source, Iterative Invalidity Strategy Aligned with Opposition Needs
We executed a comprehensive invalidity search strategy designed to uncover high-value prior art across jurisdictions and data types:
- Global patent filings and scientific publications
- Clinical trial registries and archived company disclosures
- SEC filings and historical web records
- Targeted analysis of human trial data predating the effective filing date
Our approach combined deep technical analysis with iterative collaboration, ensuring alignment with the client’s evolving opposition strategy.
We delivered a preliminary report early to facilitate strategic discussion, followed by a detailed final report mapping references against key claim limitations. Throughout the engagement, we collaborated closely with the IP leadership, responding to follow-up questions and refining the search based on procedural developments.
We delivered an end-to-end infringement assessment workflow, combining advanced imaging, material analysis, and claims mapping to provide a clear, evidence-backed view of potential patent alignment.
By integrating structural and compositional analysis with patent claim interpretation, we enabled the client to move from raw device data to actionable insights. This comprehensive approach ensured that every finding directly supported their evidence-of-use evaluation.
