PatCheck Extension

Overview of Key Features

The PatCheck Extension simplifies patent research by displaying the simplified legal status of a patent directly in the result list of public patent databases. The protection status is visible at a glance without the need to consult additional sources.

Installation and activation via the Chrome Web Store or Edge Web Store are required for use.

Supported platforms: Espacenet, Google Patents, WIPO Patentscope, USPTO PPUBS.

Color-coded display of protection status in the result list

  • The patent number is color-coded to allow an immediate assessment of the protection status:
    • Red: Protection in force
    • Orange: Application pending
    • Green: No protection
    • Violet: File inspection required

This color coding provides quick orientation during research.

Overview of the global patent protection of an invention

  • Clicking the icon next to the patent number opens an overview showing the simplified legal status of all active family members of an invention.
  • The overview displays the countries in which the invention is filed for patent protection or already granted.

This provides a compact view of the international protection landscape.

Saving patents to PatCheck during research

  • Patents can be saved directly from Espacenet, Google Patents, WIPO Patentscope, and USPTO PPUBS into PatCheck.
  • All relevant results from different patent offices are centrally consolidated.

This supports structured processing of collected research information.

Monitoring function for individual patents

  • Patent monitoring can be activated directly in the result list.
  • Automatic notifications are sent when the protection status of a monitored patent changes.
  • New patents belonging to the same invention (new family members) are also reported.
  • Continuous observation of the simplified legal status is supported.

This monitoring reduces the manual effort required to track developments in protection status.

Adding notes to individual patents

  • Notes can be created for each patent during research.
  • Notes are displayed automatically for all related documents of the same invention.

This enables consistent documentation within a research process.

Extended CSV export in Espacenet

  • The Espacenet CSV export is extended to include the current simplified protection status.

This allows the data to be processed and analyzed more easily.

Summary

The PatCheck Extension enhances public patent platforms with a clear and easily understandable representation of the simplified legal status - both for individual patents in the result list and for entire patent families.

In addition, features such as saving patents, monitoring, and note management support the structured analysis and documentation of patent information.
