Evaluating Large Patent Portfolios – Hybrid Approach

Home / Blog / Intellectual Property (IP) / Evaluating Large Patent Portfolios – Hybrid Approach

Evaluating huge patent portfolios for infringement and evidence of use (EoU) is a daunting task, being each time and labor-intensive. We have developed a method that simplifies the entire process. Our hybrid method is unfold throughout three phases:

  • Automated ranking & categorization based on the likelihood of infringement
  • Manual detailed analysis for EoU on leading databases
  • Drafting of customized claim charts

Phase 1

Phase 1 involves Automated Patent Portfolio Pruning, wherein, using our proprietary tool XLPAT we rank the patents in a Patent Portfolio into three categories – Gold, Silver & Bronze. 

Gold patents are the ones that have a high likelihood of getting infringed by products manufactured by competitors followed by silver and bronze patents.

Phase 2


Our Subject matter experts (SMEs) start with an initial evaluation of the Gold category patents. Here too we employ a two-pronged approach by using both human intelligence and our in-house tools to identify EoU effectively & accurately. 
Our advanced analytics tools that use NLP help identify and search for Standards and further map them with patents. The latest addition to our smart tool arsenal is one that converts Youtube video speech to text. This tool helps our SMEs analyze videos linked to competitor products rather quickly.
Phase 3
With the completion of the EoU analysis, our teams then start to prepare claims charts for the products identified. The EoU claim charts consist of the earliest launch date of the product/service, proof of sale, proof of use, revenue generated by the product, and additional information that could prove relevant for the client.
