Infringement Contentions


What does the search mean?

Infringement Contention refers to the document disclosed by the plaintiff to the defendant specifying the product that is infringing certain claims of the patent. This infringement contention document is created to clarify to the defendant how the product infringes one or multiple claims of the patent owned by the plaintiff. The document comprises evidence of infringed claim elements of the plaintiff’s patent. The evidence should have clearly explained how the product is similar to infringing claim elements.

Challenges Faced [by the lawyer if he wants to do infringement contention himself]

Different challenges can be faced by an individual while trying to perform infringement contention.

  • Lack of Resources: The infringing product/process needs to be verified clearly which causes the analyst to analyse the product/process thoroughly using multiple resources. However, it may be difficult for an individual to have access to multiple resources which may lead to unverified or partially verified data.
  • Time-Consuming: The verification of data related to the product/process is time-consuming as one needs to analyse the product/process from scratch. So, it may not be very efficient for an individual like a lawyer, to perform the verification.
