Subject-matter experts conduct searches in patent and non-patent databases
Prior art searches are essential to invalidating (or validating) patents. Prior art searches in patent litigations are tougher and require unconventional approaches because the searcher is trying to outperform the patent examiner. A thorough prior art search identifies potential weaknesses in a patent, and that information can be used to build a stronger case.
LitAgility’s team of subject experts is highly skilled at conducting prior art searches. Our approach involves not only human experts but also proprietary Deep Web and AI / ML tools. Searches are typically conducted on diverse sources, such as patents, scientific articles, conference presentations, websites, YouTube videos, marketing brochures, and more.
The search involves multiple steps as described below:
- Comprehensive search in multiple sources as mentioned above
- Analysis of the hits obtained based on key patent claim elements
- Charting of claims against key prior art references, with excerpts and drawings citations
- Highlighting of key 102/103 references
Our technical experts use a narrow-to-broad search approach on most projects. This approach maximizes the probability of finding key art. Frequent interactions and iterations with clients ensure that the results fill gaps in arguments as much as possible.
Search Approach Example: Narrow to Broad Search Approach
Client deliverables:
- A PowerPoint/Excel/Word report containing the list of relevant prior art, along with source pdf documents
- Access to an intuitive interface with rich text evidence organized by claim element within BridgeIP™. This makes reviewing, annotating, commenting, and exporting to templated charts easy.
- Detailed search strategy report with keywords and class codes searched
