What are the reasons that may lead to the inadmissibility of a claim for compensation as an ancillary claim in an intellectual property infringement lawsuit?

The court may decide not to accept the claim for compensation as an ancillary claim in an intellectual property infringement lawsuit if the element of fault is not conclusively proven, or if the merits of the compensation claim require a more specialized examination that may prolong the duration of the original case, thereby allowing the right holder to submit the claim for compensation in an independent lawsuit.
