Dear all,

As an IP lawyer in Belgium, I would like to ask if you'd know by any chance a case law involving this situation (whatever the origin of this litigation and the type of IP):

a company exploits an IP without the authorization of the creator and of his producer/editor/etc (licensee or assignee). but the latter does not accept to sue this infringer because it appears it is a related company (parent company or subsidiary of the infringer).

Still, the creator wants to enforce his rights against the infringer and, possibly, his cocontractor.

Do you know case law about this issue? I cannot find any!

Thanks

Elton
