ImmunoGen (Nasdaq: IMGN) and Seattle Genetics (Nasdaq: SGEN) provide technology that drug companies use to more efficiently deliver their medicines into patients.

Fool contributor Brian Orelli reported this week that Novartis (NYSE: NVS) recently paid $45 million up front to license ImmunoGen's Targeted Antibody Payload technology. For each drug developed, ImmunoGen could get $200 million in milestone payments, in addition to royalty payments if the drug makes it to market.

"It's pretty clear that targeted antibodies are the wave of the future," Brian wrote. "Big drugmakers are going to turn their antibody drug candidates into potent killing machines, but it'll be the technology developers like ImmunoGen and Seattle Genetics that will be raking in the dough."
