* Protein Design Labs Inc., of Mountain View, Calif., granted a worldwide, nonexclusive license under its antibody humanization patents to IDEC Pharmaceuticals Corp., of San Diego. IDEC agreed to pay a licensing and signing fee of $1.3 million and will potentially pay royalties on sales of the covered product, a humanized antibody under development as a treatment for steroid-resistant inflammatory diseases. The license is Protein Design's fifth — and second to IDEC — thus far this year for humanized antibodies independently developed by others.
