  • Status: Filter by the legal status of the patent (e.g., pending, granted, expired).
  • Authority: Filter based on the patent office (e.g., USPTO, EPO).

Filtering is crucial for managing large sets of data and focusing on what's most applicable to your needs.

Tagging: Organize Your Finds

Tagging allows you to categorize the patents you find based on keywords or themes. This is especially useful when dealing with large volumes of patents or when you need to share findings with team members. Tagging helps in:
