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.
