Can eHarmony Inc. sue EliteSingles USA (Affinitas GmbH.) for patent infringement?

They both use the "29 dimensions of stupidities" feature.
Please be alerted EliteSingles in only a copycat of eHarmony. Nothing more than that! eHarmony, is a 15+++ years old obsolete site and a HOAX, based on a big scientific fraud, only sustained by big marketing budget.
The Big Five normative test had been proven/revealed as an incomplete and incorrect model to assess/measure personality of persons.

A prospective client will not perceive eDarling/EliteSingles sites as better, superior or different than eHarmony's ones.
