Litigation Services for the Medical Device Industry

Nature of our Practice

Knobbe Martens was founded in 1962 and is one of the nation’s largest and most prominent full-service intellectual property law firms. Much of the firm’s practice consists of representing clients in litigation involving all types of intellectual property disputes before federal and state courts, federal agencies such as the U.S. International Trade Commission and the U.S. Patent and Trademark Office, and private arbitrators. The firm limits its practice to its area of expertise – intellectual property law – and thus all of its litigation involves disputes concerning patents, trademarks, copyrights, trade secrets, acts of unfair competition and false advertising, rights of publicity, and related licensing and antitrust issues.

The firm represents a diverse range of clients, some enforcing their intellectual property rights and others accused of infringing the intellectual property rights of others. Our clients are a diverse group, ranging from individuals to Fortune 500 companies.

We represent companies in all areas of the medical device industry including implantable devices, temporary interventions and related tools, equipment and methods in both the therapeutic and diagnostic and screening environments. Our services in these areas include patentability searches and opinions, preparation, filing and prosecution of patent applications, non-infringement and invalidity searches and opinions, “design around” assistance, patent appeals, interferences, reexaminations and reissues, inter partes reviews, litigation, and intellectual property components of investment diligence. Our lawyers and patent scientists have degrees in biology, mechanical engineering, electrical engineering or closely related fields and many have advanced degrees including Ph.D.s and M.D.s. Many also have work experience in the medical device industry.

The firm prides itself on its outstanding success in litigation. The firm’s clients have prevailed in the vast majority of cases that have proceeded through trial. Moreover, the firm is proud of the numerous cases where its clients have succeeded without the need for a trial, by obtaining preliminary injunctions or summary judgments, or by negotiating a favorable settlement.

Many of the firm’s cases have caused the courts to decide important legal issues in published opinions. Those decisions and opinions, available for public review, show unparalleled success before both trial and appellate courts throughout the country. Below you can find a representative list of certain cases that best show the wide variety of litigation experience accumulated by the firm’s lawyers.

In addition, because many of the firm’s clients are frequently involved in intellectual property disputes in foreign countries, the firm regularly acts as a liaison with foreign lawyers in resolving those disputes abroad. The firm also acts as co-counsel with general practice law firms who desire our firm’s intellectual property expertise.

Litigation Philosophies

The lawyers of the firm are committed to approaching each case with an emphasis on achieving the client’s business goals through the litigation process. Thus, the firm is willing to assume whatever role in the litigation that best serves the client’s interests. By advising clients as to the potential benefits and risks of any lawsuit, clients are able to make informed business decisions at every stage of a litigation proceeding. Because clients typically desire to avoid litigation, and the costs normally associated with litigation, the firm routinely explores settlement and alternative dispute resolution as methods to minimize the risks of litigation. Often an out-of-court settlement is the most attractive option for many clients, and we will aggressively seek settlement if settling is in a client’s best interest.

If a case cannot be settled or won by a dispositive motion, with the client’s assent, the firm will aggressively pursue that case through trial and appeal. The firm’s success rate at trial, and in recovering lawyer’s fees from opposing parties, demonstrates our ability to advise clients prudently as to whether a case should be settled or taken to trial.

The Litigation Lawyers

The firm’s success in representing a diverse group of clients lies in the qualifications and abilities of its litigation lawyers. Because all of the firm’s litigation lawyers focus their practice on the litigation of intellectual property disputes, they are specialists in this area of the law, while also having experience prosecuting and licensing patents, trademarks, and copyrights. Additionally, our litigation lawyers have backgrounds particularly suited for intellectual property litigation. For example, the vast majority of our litigation lawyers have undergraduate or even graduate degrees in engineering, the physical or life sciences, or computer science. Virtually all of our lawyers are admitted to practice before the U.S. Patent and Trademark Office.

Before joining the firm, many of the lawyers served as law clerks for federal judges, including several judges of the U.S. Court of Appeals for the Federal Circuit, the court with exclusive, nationwide appellate jurisdiction over patent cases and appeals from the U.S. Patent and Trademark Office. Many senior lawyers in the firm have served as expert witnesses, mediators, or special masters in intellectual property litigation handled by other firms. The firm’s litigation lawyers are frequently asked to present important legal issues to appellate courts by writing amicus curiae (“friend of the court”) briefs on behalf of legal associations or industry trade groups. They also frequently write and speak on a variety of issues pertaining to intellectual property litigation to audiences worldwide.

By limiting their practice to intellectual property, the firm’s lawyers have accumulated vast litigation experience exclusively within the intellectual property field. Because the federal courts have jurisdiction over patent, trademark, and copyright cases, our lawyers have an unmatched degree of experience in the federal courts litigating intellectual property cases. Supporting the litigation lawyers are numerous other lawyers, scientists, and paralegals, enabling the firm to handle intellectual property cases of all sizes, regardless of the technology at issue.

Selected Client Litigation Victories and Accomplishments
  • Masimo Corporation
    The firm represented Masimo Corporation in multiple patent infringement cases involving pulse oximeters. After one jury trial and appeal, Masimo settled a case against a primary competitor and received $330 million and additional future royalties.  After a subsequent jury trial against another competitor, Masimo received a $466 million award, which the court subsequently upheld.
  • KFx Medical Corp.
    The firm represented KFx Medical Corporation, which owns patents directed to improved methods for attaching soft tissues to bone, which are widely used in rotator cuff repair. After a liability trial in August 2013, a jury found all three KFx patents were valid and willfully infringed by Arthrex. In October 2013, the same jury awarded $29 million in damages for the infringement. The district court granted additional damages and interest, bringing the total award to $35 million. The Federal Circuit summarily affirmed the district court judgment and the U.S. Supreme Court subsequently denied certiorari. Hundreds of thousands of rotator cuff surgeries are performed each year in the United States utilizing KFx’s patented technique.

    On July 14, 2009, the Patent Office completed the reexamination proceeding of I-Flow’s U.S. Patent No. 5,284,481. I-Flow continues to enforce its patent rights against Apex Medical Technologies, Inc. with the legal representation provided by Knobbe Martens.
