An anonymous reader writes "Ars is reporting that the patent-holding company, along with the heirs of Dutch programmer, Joannes Jozef Everardus Van Der Meer (deceased 2004), have filed suit against Facebook for violating two patents relating to social media web sites. The two patents in question were filed for back in 1998, a full four years before Facebook founder Mark Zuckerberg first entered university at Harvard. Among the claims made in the lawsuit is that Facebook's "Like" button violates one of Van Der Meer's patents. Facebook even cited one of Van Der Meer's patents in one of their own filings later on. The suit seeks unspecified damages."
