The patent litigation world is one where competent evidence could be the making or the breaking of a case. In the litigious world of a lawyer, one of the newest pieces of evidence that has been used are product disassembly reports. These reports consist of studying a product thoroughly and breaking it down into parts to gain understanding of its architecture, operations, and the means of its creation. Product disassembly reports allow a claim to patent infringement, validity, and scope litigation to be better substantiated by explaining how a product works in totality.

This article examines how product disassembly reports are prepared and their contribution to the litigation process. Their advantages over existing approaches, shortcomings of the previous attempts, and also their role in the current complex world of IP is examined.

Past Obstacles/ Challenges for Evidence in Patent Litigation

Since the application of evidence in patent litigation is always a difficult situation, and mostly it still remains so, especially when it is applied for a legal argument based on very technical and sophisticated subjects, the key issues include:

• Opaqueness of a Product's Design: Recently most of the electronic products have a high level of integration and proprietary designs that make one difficult to understand what’s actually happening inside the product unless a breakdown or thorough investigation is being carried out.
• Reliance On External Testing: Most litigators had to rely on a much more primitive external testing technique whose output could only tell the tiniest information about what the internal structure and specific functions were in the product.
• Restriction of Access: Most companies try to enforce strict protective measures on their products and their designs, for instance, very few people are able to understand or reproduce designs for reverse engineering purposes.
• Lack of Evidence: There are multiple cases where engineering plans or product information have inadequate documentation, this becomes a challenge for litigators to prove infringement or defend the patent.

The Benefits/ Advantages of Product Disassembling Reports

The product disassembling reports help circumvent most of the mentioned threats, thus giving a parallel and orderly sketch on how pieces of evidence can be collected in a patent litigation case. These include:

• Finding Non-Market Features Only Available After Dismantling: Inside a product, there are functional features and mechanisms which, by merely checking out its exterior and the market files, will not be immediately obvious. These detail oriented disassembly reports provide an insight into what the design patterns are, what materials are used, how the product is assembled, all of which can expose patents for infringe accusations.
• Making Comparisons Without Ambiguity: While arguing an infringement case, the controversial product is placed next to the patent product. This makes it easier to determine whether infringement occurred. This is made easier by disassembly reports which provide instructions and elaborate how the features of the product are or are not patentable.
• Improvements on The Professor’s Expertise: With use of detailed disassembly reports, an expert does not have to rely on their opinion during litigation. It is safe to say he/she will be asked to show credible and relevant proof of a dispute and this is one of the easier paths the expert can take.
• Facilitating The Challenge for Validation: Disassembly reports allow for the location of prior art immobilized within goods and therefore can facilitate the argument for the dismantling of a misconceived patent. When it can be shown that the patented feature is not new, then litigators can argue that the patent is overreaching or has been given wrongfully.
• Precisely breaks down these technologies: With the advent of recent products, the disassembly report is able to break down complex technologies into simpler bits that are easily understandable for jury, judges, and even lawyers working on the contrasting side.

Conclusion

To sum up, these disassembly reports of products have changed the notion of gathering evidence in a patent case. Such reports offer several advantages compared to patent litigation issues encountered earlier since they provide accurate information about a product in an unbiased manner. Furthermore, databases are useful in revealing hidden information about a product, which aids in expert evidence, and makes it easy to compare. For these reasons, they are very crucial in patent defense and patent claiming. With technological advancement, the complexity of products is set to increase as well; hence, such reports will be of great importance.
