European Patents

September 12, 2017

In my patent analysis practice, I continue to see an increase in requests to review European (EP) patents. This is likely due to a variety of reasons, including case law decisions in the United States in recent years, along with the promise of a European Unified Patent Court (UPC). In any case, I find it advantageous as a US-based patent analyst to be familiar with European patent practice because there are many differences from US practice, and of course there are different resources available for European patent review.

For example, while Google Patents provides support for EP patents, there is additional information available from European Patent Office (EPO) websites such as Espacenet (technical information) and European Patent Register (legal information, like the USPTO’s Public PAIR). And once a European patent is granted, it is currently enforced in each separate designated contracting state (nation) after validation procedures (such as providing language translations); renewal fees are also thereafter paid to each contracting state. This makes determining current status more difficult — one must determine in which nations the granted patent is enforceable (a topic for a future blog post).

With regard to European patents, the Chrome browser “Patent Claims Tree” extension has been updated to:

  1. provide a link to both Espacenet and the European Patent Register for a given EP patent, such as when viewed in Google Patents
  2. handle claims viewed in Espacenet
  3. provide enhanced German claim text analysis
  4. fix claims extraction for EP patents in Google Patents (based on updates to Google Patents)
