3D4Medical Ltd., et al. v. Orca Health, Inc. (S.D. Cal.)

Represented 3D4Medical Ltd. in actions against Orca Health, Inc. In one action, we defended 3D4Medical in Utah Federal District Court where Orca Health alleged over 10 state and federal tort claims, including unfair competition, trade secret misappropriation, and infringement of its trademarks, trade dress and patents. Before discovery began, multiple motions to dismiss the complaint under rule 12(b)(6) were filed as well as a motion to disqualify plaintiff’s counsel and to invalidate the asserted patents as being directed to ineligible subject matter. In addition, a separate lawsuit was filed in the Southern California Federal District Court against Orca Health for copyright infringement, trade dress infringement, unfair competition and breach of obligations under its End User License Agreement with 3D4Medical. After having already dismissed one of the two patents from case and just before the hearing on the Utah preliminary motions, a favorable settlement of both cases was reached.
