These are patents by a cleaning company in Denmark named Vikan. I would like to understand if these are patents that are European only or also US patents. Also, when I look on the European patent website, Espacenet, on INPADOC legas Status for WO2005108015, it shows PRS Code WWW as one of the last PRS dates and says, WIPO INFORMATION: WITHDRAWN IN NATIONAL OFFICE". Does that mean that they withdrew their patent application for this item?
Let me answer you with.
1) If a patent is of series EPXXX..XX, it is filed only in EP. It doesn't get patent rights in US. 2) WO2005108015 is a WIPO application. It gives an inventor liberty/time to file patents in other countries taking priority from WIPO application. 3) So, after filing WIPO application, the inventor can file another patent in US and other countries. 4) Basically, same invention is filed in different countries. 5) And, these are clubbed under one as a 'family members'.
Specifically, in your case, WO2005108015, has only two members. DK200400741 and WO2005108015. So, as it doesn't have any US patents in family.
