Litigation-Ready Evidence of Use (EoU) & Patent Infringement Claims
Build an unassailable case. TAEUS provides clear, technically precise Evidence of Use charts and infringement analysis to support high-stakes patent litigation and licensing campaigns.
Definitively Prove Infringement with Technical Engineering Evidence
High-stakes patent litigation and assertive licensing require concrete proof. Suspecting a competitor is infringing on your intellectual property isn’t enough—you need verifiable data that connects their product's functionality directly to your patent claims.
For thirty-five+ years, TAEUS has provided comprehensive litigation support for both sides of the aisle. We help patent owners establish rock-solid assertions to pursue damages, and we assist companies in successfully defending against meritless infringement claims using objective, empirical data.
Custom-Tailored EoU Charts and Claim Mapping
We translate complex technical findings into clear, accessible evidence that any judge, jury, or opposing counsel can easily understand. Our engineering team digs into the absolute fundamentals of a product—whether that means analyzing a few critical lines of code or tracing a transistor on a microchip.
Comprehensive Evidence of Use (EoU) Charts
We deliver detailed, color-coded claim charts that map every element of your patent claims directly to the target product's components or processes.
Technical Litigation Support
Our findings are compiled into custom reports designed to serve as the definitive "smoking gun." From initial technical discovery to providing expert witness insights, we support your legal team through every phase of a dispute.
Deep Synergies with Reverse Engineering
An airtight EoU chart relies on flawless technical data. By leveraging our in-house patent reverse engineering services, including hardware teardowns, semiconductor circuit extraction, and software decompilation, we uncover hidden infringement that standard discovery methods miss.
Frequently Asked Questions About Evidence of Use (EoU)
What is an Evidence of Use (EoU) chart?
An Evidence of Use chart is a legal and technical document that maps the specific claims of a patent directly to the features, components, or software code of a competing product to demonstrate clear infringement.
How does technical claim mapping help in assertive licensing?
High-quality claim mapping gives you immediate leverage in licensing negotiations. Presenting a competitor with undeniable technical proof of use drastically increases the likelihood of a successful, out-of-court licensing agreement.
Can your EoU analysis support patent defense?
Absolutely! If your company is facing allegations of infringement, our team can conduct non-infringement analysis and prior art searches to prove your technology does not overlap with the asserted patent claims.
