T 1024/18 – Another Turn of Events for Description Amendments
This decision appears to bring description amendments back to requiring amendments to the description to conform with any amended…
From 1 November 2014 the European Patent Office will change its practice and allow additional searches for European regional phase patent applications (Euro-PCT applications) that are found to lack unity of invention.
At present there is a discrepancy between direct filed European patent applications and European patent applications which are European regional phase applications derived from an International (PCT) filing, a so-called Euro-PCT.
For a direct filed European patent application if the search examiner finds that the claims define more than one invention, the applicant is provided with the opportunity to request additional searches for the unsearched subject matter. If additional searches fees are made, the applicant can then pursue their application based on any of the searched inventions. If they take this option they then also have a greater flexibility with respect to amending their claims; because the EPO does not allow amendment of the claims to include any unsearched subject matter. Also, they have the opportunity to file a respective divisional patent application for any of the other searched inventions with the benefit of the results of the search prior to incurring the cost of filing a divisional patent application.
This flexible approach is presently not the case for Euro-PCT patent applications because there is no opportunity during the European regional phase to request additional searches when a lack of unity is found. For this type of application there is only an opportunity to request additional searches during the International phase.
Currently, when filing a Euro-PCT application for which the EPO was the International Search Authority (ISA) or International Examination Authority (IEA), the claims of the Euro-PCT must be based on one of the searched inventions. For a Euro-PCT for which the EPO was not the ISA or IEA, for example the USA or Japan was the ISA or IEA, the claims can optionally be based on an unsearched invention; this is because a supplementary search is conducted by the EPO for this type of application. This therefore leads to a further discrepancy and puts Euro-PCT applications for which the EPO was the ISA or IEA at an even further disadvantage.
In either case, for a Euro-PCT application, regardless of the ISA or IEA, it is presently not possible to pay additional search fees when a lack of unity is identified for the first time during the European regional phase.
However, the option of requesting additional searches will be available on or after 1 November 2014 for Euro-PCT patent applications as follows:
The above will be possible regardless of whether additional searches were requested during the International phase.
This will place all European patent applications, regardless of their filing origin, on a more even footing and allow the same flexibility of approach for a Euro-PCT application in the ongoing prosecution, which is presently available to direct filed European patent applications.
