[Patentpractice] PoA/Representation of licensee and licensor?

Wed Jun 11 15:28:06 UTC 2025

"claims relating to the Patent Rights [i.e., full interest in several
existing foreign patents]."  Reading between the lines, there is the
possibility that you are taking responsibility for applications in their
international phase or even before an international filing. If so, beware
of switching applicants, and see 1.46(b)(" person who otherwise shows
sufficient proprietary interest in the matter must have been identified as
the applicant for the United States in the international stage of the
international application or as the applicant in the publication of the
international registration under Hague Agreement Article 10(3).").  And, if
the international phase claims Paris priority to an earlier filing, beware
of diversity of the applicants under Paris article 4C.(4), PCT article
8(2)(a).

 Regarding your question, though, I think a joint representation is an
ethics nightmare.
