In its lawsuits, Howmedica says the three have caused it "irreparable harm" by selling products that infringe the patent. The company maintains that it received the patent covering a cup that fits into the pelvis and features a dual-locking mechanism almost a decade ago. After a re-examination, the validity of the patent was confirmed last year.

Howmedica has asked that the companies be barred from marketing any product that infringes the patent, as well as for monetary damages.
