TECHNICAL SERVICES · EVIDENCE OF USE (EOU) AND INFRINGEMENT ANALYSIS
Evidence of Use and Infringement Analysis
Identify evidence of patent use through comprehensive claim-to-product analysis, enabling confident enforcement, licensing, litigation, and strategic IP decisions.
WHY IT MATTERS
The problem it solves
Helps determine whether your patent is being infringed by a product, system, or process
Supports informed enforcement, licensing, acquisition, and litigation decisions with evidence-backed technical analysis.
Reduces uncertainty by identifying publicly available evidence demonstrating product implementation.
Assists patent owners in evaluating the commercial value and enforceability of their patent portfolio.
Enables organizations to prioritize high-value infringement and licensing opportunities.
Provides technical evidence to support pre-litigation investigations and claim chart preparation.

What it does
Determining whether a product, system, or process practices the elements of a patent claim can be time-consuming and technically complex. Potentially relevant products and technologies may be difficult to identify and establishing how they map to specific claim elements often requires detailed technical research and analysis. A thorough EOU search provides the evidence needed to evaluate potential infringement and inform enforcement, licensing, and other strategic decisions.
Trexo conducts comprehensive EOU searches to identify products, systems, and processes that may practice one or more patent claims. Through detailed claim-to-product mapping and technical analysis, we identify and document evidence supporting each relevant claim element. Our breadth of technical expertise helps uncover relevant EOU evidence while reducing the time and cost of searching.

COMMONLY ASKED QUESTIONS
About Evidence of Use (EOU) and Infringement Analysis
What sources do you use to identify evidence?
We analyze product manuals, datasheets, technical specifications, white papers, regulatory filings, websites, videos, product demonstrations, standards, developer documentation, product teardowns, conference presentations, research publications, and other publicly available technical resources. We also perform live experiments wherever possible, to gather the evidences.
Do you prepare claim charts?
Yes. We prepare detailed claim charts that map each claim limitation to corresponding evidence identified from the respective sources.
What technologies do you support?
Our team has expertise across mechanical engineering, electronics, electrical systems, software, AI/ML, telecommunications, semiconductors, robotics, medical devices, pharmaceuticals, biotechnology, life sciences, chemicals, materials science, optics and photonics, automotive, industrial automation, energy technologies, aerospace, consumer products, and many other technical domains.
Can the analysis identify evidence that is not explicitly stated?
Yes. Where appropriate, our experts infer product functionality from multiple publicly available sources and correlate the findings with patent claim limitations. Such inferences are clearly identified and supported by technical reasoning.
Can you analyze multiple products against the same patent?
Yes. We can evaluate multiple products, product families, or competitors against the same patent to identify the strongest Evidence of Use opportunities.
What makes your Evidence of Use and Infringement Analysis service different?
Our service combines deep technical expertise, comprehensive evidence collection, meticulous claim-by-claim mapping, technology-specific subject matter expertise, customized methodologies, and evidence-based reporting to deliver actionable insights that support patent enforcement, licensing, portfolio monetization, due diligence, and pre-litigation decision-making.
Why should I use a human over AI?
AI is excellent at searching and processing large volumes of data, but patent searching often requires technical interpretation, search strategy, and judgment. That’s where Trexo’s engineers and scientists add value to your patent search needs.
