EOU/CLAIM CHART PREPARATION

Evidence of Use (EoU) chart is used to define the extent a claim ‘reads onto’ a product, process, and or standard. Detailed evidence of use charts help in licensing agreements, pre-litigation research, and patent transaction opportunities

Evidence of Use (EoU) Claim Chart helps you and is of great value and is used to see how a product or service infringes a patent’s claim. 

• Recognize potential infringement of your existing patents. If you are selling patent assets, proof of patent infringement can strengthen the terms of the sale.
• Identify vertical technology areas or silos. Lots of technologies make use of common subsystems or techniques of getting their means. So, provisional patent and product literature studies seriously help in identifying the right target companies. We at PatentsKart, work closely with you during this significant phase to make out the number and kind of technology silos that set up the scope of your study.
• Evaluate potential patent infringement analysts; work with your specialist and counsel to analyze your patent portfolio and make out the candidates that have a high potential of being an infringer.
• Attorneys analyze these charts to prove infringement. Claim charts are extremely helpful in patent licensing negotiations, pre-litigation research and even during litigation. Claim charts provide the user with a verbal explanation of how they differ from one another so that if there is any overlap between patents on an invention it can be more easily determined when negotiating prices or validating ownership claims without having lawyers do all work for them.

EoU charts are typically generated in the following steps:

• Searching: Every infringement study starts with search and analysis based on the claims of the subject patent. Unlike a Patent Validity Search, EoU centers around patent literature that postdates the subject patent. As patent literature offers the detail that is frequently lacking in the actual product literature, this initial search provides a landscape of competitive and non-competitive companies. On a similar pattern, we perform a direct Google search for the existing products in the market
• Claims mapping: Using this information, we perform comprehensive searches of product literature, product catalogs, corporate websites, press releases, and more. We recognize products to pair with related patents and generate claims charts. The claim charts map the product literature, product terms, patents, figures, and pictures to the claims of the patent you are studying
• Analysis: In some cases, products are bought and reverse engineered. For some technologies, we can also make third-party laboratory analysis services to improve your claims charts further
• The release of results: We carry this powerful body of information in clear, well-organized reports and claims mapping charts

Yes. Whatever your intellectual property management goals may be (defensive, commercialization, or assertion), routine monitoring of the market for potential infringement, and maintaining a set of infringement-indicative claim charts will serve to increase the marketability and transaction probability of your patent portfolio. The first question that most buy-side parties will ask is: “do your patent assets have claim charts/evidence of use?
