Infringement & EoU — Final Code

What is an Infringement or Evidence of Use (EoU) Search?

A Patent Infringement Search (often combined with an Evidence of Use search) is a targeted investigation to identify products, processes, or technologies in the market that may be using your granted patent claims without authorization.

Unlike a Freedom to Operate (FTO) search, which is defensive, an Infringement Search is offensive and strategic. It involves a detailed, element-by-element comparison between your patent’s independent claims and a competitor’s product specifications.

The objective is to determine whether every essential element of your patented invention is being commercially exploited without your consent.

Frequently Asked Questions

Find answers to top questions about Patentability Search, novelty evaluation, and the patent filing process.

What is an "Evidence of Use" (EoU) chart, and how does it prove infringement? ▼
An EoU chart is a side-by-side comparison mapping each specific element of your patent claim to the features found in a competitor's product, providing a clear visual "receipt" of infringement.
Can you perform "teardowns" of competitor products to find hidden infringement? ▼
Yes. We physically or digitally dismantle products to find "hidden" infringement in internal hardware, circuitry, or embedded source code that isn't visible from the outside.
How do you map patent claims to specific product features? ▼
We use "Claim Charts" where the left column contains the legal claim language and the right column contains technical proof, such as annotated photos, lab results, or code snippet.
What is the difference between a "Claim Chart" and an "EoU Chart"? ▼
A "Claim Chart" is the structural format; an "EoU Chart" is the specific application of that format used to demonstrate that a product on the market is currently utilizing your IP.
Can you identify potential licensees for my patent portfolio? ▼
Yes. We identify companies whose product lines overlap with your patent claims, highlighting them as prime candidates for revenue-generating licensing deals.
Do you monitor the market for new products that might infringe on my IP? ▼
We offer "IP Watching" services, providing alerts the moment a competitor launches a product or service that enters your protected technical space.
What happens if the infringement is happening in software or "under the hood"? ▼
We utilize advanced reverse engineering, API analysis, and technical documentation review to uncover evidence that is not accessible via standard user interfaces.
How "court-ready" are your infringement reports? ▼
Our reports are designed to meet legal requirements of countries of interest and provide a high-confidence technical basis that attorneys can use to initiate litigation or C&D letters.
Do you cover global markets or just specific jurisdictions? ▼
We search global product databases, international import/export records, and localized technical forums to find infringement across all major jurisdictions.
How do you handle "Standard Essential Patents" (SEPs) and mapping to industry standards? ▼
We map your patents to specific industry standards (like 5G, Wi-Fi, or HEVC). If a product is compliant with that standard, the report demonstrates it must infringe your patent.
