501(c)(4) Organizations: Giving with an Edge

These nonprofit entities—which are commonly known by reference to Section 501(c)(3) of the Internal Revenue Code—are operated exclusively for a broad range of charitable purposes.  501(c)(3) organizations come in a wide range of flavors, including private foundations, donor-advised funds, and public charities.

The firm has defeated an appeal of a decision in favor of our client, Janssen Biotech, Inc., entered by an arbitral tribunal last year.  In that arbitration, Genmab A/S demanded milestone payments and an extended royalty term with respect to the subcutaneous formulation of daratumumab (marketed as DARZALEX FASPRO in the United States) under the relevant license agreement between Genmab and Janssen. Genmab had sought an award of $405 million plus interest in accrued milestone payments for DARZALEX FASPRO, as well as a declaration that Genmab was entitled to a new 13-year royalty term from the date of DARZALEX FASPRO’s first commercial sale...
