In patent licensing and litigation, identifying a potentially infringing product is only the beginning. The real value lies in clearly demonstrating how that product practices the patented invention. LogicApt’s Evidence of Use (EoU) Chart service is designed to provide precisely that — a structured, claim-by-claim analysis showing how specific products, systems, or technologies overlap with the asserted patent claims.
Our Evidence of Use Charts are built to help patent owners, law firms, licensing teams, and litigation professionals establish a strong technical foundation before initiating licensing discussions, filing litigation, or preparing enforcement strategies. The objective is to create a clear, organized, and defensible presentation of infringement indicators that can be easily understood by attorneys, experts, business teams, and decision-makers.
At LogicApt, the process begins with a detailed analysis of the patent claims and the identified target products. Our team studies publicly available technical evidence such as product manuals, technical specifications, white papers, source materials, marketing documentation, teardown reports, user guides, standards documentation, videos, archived webpages, and other credible technical sources.
We then map the identified product features against the relevant claim elements in a structured element-by-element format. Each chart is designed to clearly demonstrate where and how the target product aligns with the patented technology.
One of the defining features of LogicApt’s EoU charts is our use of color-coded mapping formats. These visually structured charts make it significantly easier to understand claim coverage, identify overlapping functionalities, and quickly interpret infringement positions. The color-coded approach improves readability and allows legal teams to rapidly assess strengths, gaps, and strategic opportunities without navigating overly dense technical documentation.
Our Evidence of Use Charts are frequently used for:
- Pre-suit investigations
- Licensing and monetization campaigns
- Litigation preparation
- Demand letters and negotiations
- Portfolio valuation
- Litigation funding assessments
- Internal enforcement strategy discussions
The service also works as a natural continuation of our Target Scouting process. Once potential infringing products and companies are identified, clients can selectively choose the targets they wish to pursue, and LogicApt develops detailed EoU charts tailored to those products.
At LogicApt, we understand that effective EoU charts must balance technical depth with practical usability. Our goal is not simply to create technical documentation, but to provide litigation-ready analysis that helps clients make informed enforcement and monetization decisions with greater confidence.
Whether you are preparing for licensing discussions, evaluating litigation opportunities, or building a broader patent monetization strategy, LogicApt’s Evidence of Use Charts provide the technical clarity needed to move forward strategically and effectively.
