Business Court Grants Partial Injunction on Non-Compete, Applies Blue Pencil Doctrine to Overbroad Covenant

In Galderma Laboratories v. Brenner, the Texas Business Court's Eighth Division granted in part a temporary injunction enforcing a non-compete agreement against a former executive, but reformed the covenant's scope under the blue pencil doctrine after finding certain service restrictions overbroad.
