For the lawyers at Allergan Inc., providing top-flight legal counsel is only part of the picture.

Allergan's 36 lawyers, 23 of whom are based at the pharmaceutical company's Irvine, Calif., headquarters, primarily focus on making the company successful, said general counsel Arnold Pinkston. By enforcing patents and providing regulatory advice about marketing products, among other legal work, the lawyers play their role in improving the bottom line.
