Case Study: Defeating High‑Stakes Patent Litigation with Invalidating Prior Art

Client Profile​​

A leading law firm representing a defendant in a high‑value patent infringement litigation involving substantial claimed damages. 

 

Challenge

The defense strategy required strong, invalidating prior art capable of undermining patent validity under intense litigation timelines and scrutiny.

​

Our Approach

  • Conducted comprehensive invalidity searches across patents, non‑patent literature, legacy technical documentation, and obscure disclosures.

  • Focused on claim‑by‑claim mapping to identify novelty and obviousness challenges.

  • Prioritized litigation‑grade prior art with clear publication dates, technical disclosures, and admissibility.

  • Delivered well‑structured claim charts and supporting analysis ready for attorney review and expert use.

  • Maintained confidentiality and rapid turnaround aligned with litigation milestones.

​

Outcome

   ✓ Identification of highly relevant “patent‑killing” prior art.

   ✓ Strengthened invalidity defenses under multiple statutory grounds.

   ✓ Enabled favorable litigation positioning and negotiation leverage.

​

Business Impact
The client was able to significantly reduce litigation risk, helping avoid potential damages running into millions, while strengthening the overall defense narrative.
