According to the publication date, this patent should have expired in 2006. The last legal event recorded however is a correction made in 2007. Does this mean that is was renewed? Would an inventor correct an expired patent? Why would a renewal not be recorded as a legal event?
Not sure what you mean by "renewed". However this page
says Status=withdrawn which means it's not an active patent and may never have been actually issued. Normally we would click on "all documents" on the left to get the full records, but in this case it says files have been destroyed, which supports the idea that it's not active. My expectation is that if something of interest had happened in 2007, the file would not have been destroyed. In any case, this stems from a 1986 application. While I am far from being an expert on EPO matters, it seems unlikely that any protection to anything would linger after 28 years.
You have also asked about the US counterpart US5278057. Looking at USPTO PAIR
it is showing as expired in 2006 due to non-payment of maintenance fees, in 2006. Even if the assignees had paid the fees it would have expired in 2010 (there is a terminal disclaimer on the face of the patent).
Application was filed in 1986 and withdrawn in 1990. No patent was granted, since the applicant failed to respond to a communication from the examining division. Also, no renewal fee was paid after 1990. The 2007 change seems to merely relate to an update of the inventor record in the database. It has nothing to do with the application still being pending.
BTW, the "A3" kind code you mentioned refers to the search report when published separately. The published application itself is EP0198288 A2.
