1. Evidence of Use (EoU) Search and Claim Evidence of Use (EoU) Search and Claim Chart Services Chart Services By IIP Search 1. Introduction 1. Introduction In today’s fast-moving innovation environment, simply owning a patent is not enough. What matters is whether that patent is being used, or can be shown to be used—or potentially infringed—by products or services in the marketplace. That’s where an Evidence of Use (EoU) Search and Claim Chart become indispensable tools. At IIP Search, we provide a comprehensive service that helps patent owners, law firms, licensing professionals and in-house IP teams translate patented rights into concrete, defensible evidence of use, for licensing, enforcement or transaction purposes. 2. What is an Evidence of Use (EoU) Search? 2. What is an Evidence of Use (EoU) Search? An EoU Search is a systematic investigation to identify whether a patented invention is being practiced (used) by one or more third-party products, services or standards. The objective is to map each claim of the patent to elements found in publicly-available (or otherwise accessible) product specifications, user manuals, software code, standards documents or reverse-engineering data. Key aspects of an EoU Search include: •Reviewing the patent claims (independent and dependent) and their precise language. •Identifying relevant products, systems, or services that may embody one or more claims of the patent, based on filing/issue date, market launch, publicly-available information. •Collecting and analysing evidence such as datasheets, user manuals, screenshots, product descriptions, teardown reports, industry standard documentation. •Mapping the patent claim elements to feature(s) of the product/service—i.e., “Product X includes feature A which corresponds to claim element 1”. •Producing an EoU chart (also called a claim chart) that documents this mapping in a tabular format.

2. •Providing a summary report of findings, risk assessment, possible next-steps for licensing, enforcement or further investigation. Why this matters: •Enables patent owners to demonstrate use (or potential use) of the patented invention. •Helps in licensing negotiations: evidence of infringing use strengthens your position. •Supports litigation or pre-litigation readiness: shows a clear linkage between claim language and real-world product features. •Supports IP portfolio management by identifying valuable patents that are actively being used (by others) and thus may merit further monetisation. 3. What is a Claim Chart? 3. What is a Claim Chart? A Claim Chart is the deliverable document (often a multi-page table) that presents, claim-by- claim (and often element-by-element), the mapping between the patent claims and the identified product/service features and evidence. Typically, in one column you will have the patent claim language broken into elements/limitations; in the adjacent column you present the evidence of use – referencing product documentation, screenshots, figures, datasheets, standards citations etc. A well-crafted claim chart does more than just list matches—it explains how each claim element is met (or not met) by the target product or service, with reference to credible sources. It serves as the core of an infringement-analysis narrative. 4. Why Choose IIP Search for Your EoU & Claim Chart 4. Why Choose IIP Search for Your EoU & Claim Chart Needs? Needs?

3. •Defensible documentation: We focus on producing charts and reports that stand up to scrutiny—whether for internal licensing discussions, M&A due diligence, or enforcement campaigns. •Global coverage: Whether your patents cover US, Europe, India or other jurisdictions, we can handle multi-jurisdictional product markets and timelines. •Action-oriented insights: Beyond just producing a chart, our deliverables include strategic commentary—e.g., “Product A appears to meet 4 of the 7 independent claim elements; further investigation is recommended for feature X”, or “We identified product launches post-patent issue date that may merit licensing outreach”. 5. Our Service Workflow 5. Our Service Workflow Below is a high-level overview of how we deliver our Evidence of Use & Claim Chart services: Phase Description We collaborate with you to define the patent(s) in scope, target products/services, jurisdictions, timeline and deliverable level (licensing vs litigation) 1. Project kick-off & scope definition 2. Patent claim analysis We dissect the patent(s), map claim elements, establish key claim features, conduct relevant prosecution history review if needed 3. Product/market scouting We identify potential accused products/services—based on market launch, publicly-available documentation, standards involvement We collect product specification sheets, user manuals, industry standards, teardown reports, press releases, etc-—and evaluate relevance to claim elements 4. Evidence gathering We prepare the claim chart mapping each claimed element against the product feature + evidence, including cross-references and supporting data 5. Claim chart preparation We provide an executive summary, scoring or gap-analysis (e.g., how many claim elements are met, any missing links, recommended next steps) 6. Strategic commentary & report

4. Phase Description We send the deliverables to you, incorporate your feedback, and finalise the report and claim chart in your preferred format (PDF/Excel) 7. Review & delivery 6. Use 6. Use- -Cases & Client Benefits Cases & Client Benefits Here are typical scenarios where our EoU & Claim Chart services bring high value: •Patent licensing: You own patents and wish to approach potential licensees. A clear EoU chart shows how the patents are practised in the market—strengthening your negotiation position. •Enforcement readiness: You suspect a product infringes your patent. The claim chart shows precisely how each claim element is mapped to the accused product—helping counsel evaluate strength of the case. •Due diligence / M&A: A potential buyer or investor wants to assess the monetisation potential of your patent portfolio. EoU charts provide a transparent view of which patents are actively being used and in which markets. •Product launch risk-assessment: Before launching a new product, you want to assess whether it may infringe third-party patents. We can run EoU investigations on relevant competitor patents to reveal risk. •Portfolio monetisation: You wish to identify “sleeping” patents that may be quietly practised by others. EoU mapping can uncover where others are using your inventions—opening licensing or enforcement opportunities. 7. Case Study (Hypothetical) 7. Case Study (Hypothetical) Client: A mobile electronics company with a patent covering a novel charging architecture. Challenge: The client believed rival manufacturers were using the patented architecture in their latest devices but lacked concrete proof. Our Approach: We analysed the patent claims, identified major devices launched after the patent’s issue date, collected publicly-available teardown data, manufacturer datasheets and standards documents. We mapped each claim element to features in the accused devices and prepared a detailed claim chart. Result: The client obtained clear mapping showing >80% of claim elements were present in two competitor devices. They used the chart to open licensing negotiations and to

5. strengthen their enforcement strategy. Benefit: The client gained actionable evidence, elevated the value of their patent, and avoided the uncertainty of informal speculation. 8. Frequently Asked Questions (FAQs) 8. Frequently Asked Questions (FAQs) Q1. What is the difference between an EoU Search and a regular Patent Infringement Search? An infringement search typical asks “which patents may this product infringe?”. An EoU Search starts with your patent and asks “which products/services may be practising this patent (and how)?”—and then maps the evidence. Q2. How long does an EoU & claim-chart project take? It depends on patent complexity, number of products, jurisdictions, and depth required. Typical turn-around is 4-6 weeks for a focused analysis; more complex portfolios may take longer. Q3. Can the deliverable be used in court or arbitration? Yes—our deliverables are structured to be defensible: clearly citing sources, mapping each claim element, and providing credible evidence. They are well suited for licensing discussions, pre-litigation, and litigation support. Q4. Is reverse-engineering required? Not always. In many cases, publicly-available product literature (manuals, datasheets, press releases) suffices for mapping claim elements. In more contested cases, reverse-engineering or teardown reports may be incorporated as needed. Q5. Will you cover global products and multi-jurisdictional patents? Yes. We tailor the scope as per your needs—whether US-only, Europe, India, Asia-Pacific or global. We identify product markets relevant to the jurisdictions of interest. Q6. What do you deliver? Typically: •A detailed claim chart (Excel and/or PDF) mapping each claim element to product feature + evidence. •A report summary/executive overview, including key findings, gap-analysis, risk/monetisation insights. •Supporting source-list/documentation (product manuals, datasheet links, standards references).

6. 9. Why This Matters for Your Business 9. Why This Matters for Your Business Patents are only as valuable as the ability to enforce, license or monetise them. Without credible evidence that the patented invention is being used (by you or by a third party), your options for monetisation are limited. A high-quality EoU Search and Claim Chart transforms your patent from a dormant asset into actionable intelligence. By working with IIP Search: •You gain visibility into how your patents map to real-world commerce. •You are better equipped to negotiate licences or pursue enforcement confidently. •You reinforce your IP strategy with data-driven evidence rather than mere assertions. 10.
