Read the whole patent

Listed from its EPO record in Patent Yard's archive of European patents past their term. Its claims, description and drawings are in the EPO PDF and on Google Patents, and the Claude kit works from them.

Why it's free to use

• Filed October 20, 2005 and granted March 16, 2011. A European patent lasts at most 20 years from filing, so its term ended October 20, 2025.
• Supplementary protection certificates extend only medicine and crop-protection patents, and it isn't classified as either.
• We check European rights only. A US or other national patent in its family could still be in force: check its family on Espacenet or Google Patents.
