📊 Evidence of Use (EOU) Charts

Demonstrating Real-World Patent Infringement with Precision

At IIPT Solutions, our Evidence of Use (EOU) charts are expertly crafted tools designed to map the elements of a patented claim directly to publicly available information—typically competitor products, technical documents, or user manuals. These charts play a critical role in licensing negotiations, litigation strategies, and valuation of intellectual property assets.

🔍 What is an EOU Chart?

An EOU chart, also known as an Infringement Chart, is a structured table that aligns the specific claim elements of a patent with evidence showing how a third-party product or process embodies those claims. It serves as compelling documentation for:

  • Licensing discussions
  • Patent assertion
  • Due diligence for M&A/IP valuation
  • Enforcement strategies

⚙️ Our Process

At IIPT Solutions, we combine legal expertise and technical rigor using industry-leading tools and methodologies:

  1. Patent Claim Dissection
    Each claim is parsed and interpreted accurately using USPTO/EPO claim construction guidelines.

  2. Source Identification
    We gather publicly available material such as product datasheets, manuals, teardown reports, and videos.

  3. Evidence Mapping
    Precise annotations match every claim element to relevant features in the third-party product or process.

  4. Expert Review & Compliance
    Our EOU charts adhere to standards required by courts and licensing entities globally, including U.S. District Courts and PTAB.
