INTRODUCTION The public's interest in medicine and good health is substantial. However, this interest is harmed when important medical devices or pharmaceuticals, although infringing on valid patents, are suddenly taken off the market after a court grants a permanent injunction. While permanent injunctions were automatically granted by the Federal Circuit before the Supreme Court's holding in eBay v. MercExchange, courts now have more discretion to deny injunctive relief. Now that courts have this newfound discretion after eBay, the public should no longer expect to be harmed by the sudden removal of medical supplies from the marketplace. Unfortunately, this has not been the course that all courts have taken post-eBay. To protect the public interest, courts should apply a rebuttable presumption in medically-related patent cases, finding that the public interest weighs against granting an injunction. This Comment highlights the necessity for this rebuttable presumption to help protect the public health. Part I provides a brief overview of the history of injunctive relief in patent infringement cases prior to 2006 and the few exceptions applied to deny injunctions. Part II analyzes the eBay v. MercExchange case, from its beginning in the district court to its remand back to the district court after the landmark decision in the Supreme Court. Next, Part III provides an overview of general trends regarding injunctive relief in patent infringement cases post-eBay and also analyzes the courts' treatment of injunctive relief in recent cases in the medical patent space. Finally, in Part IV expresses the importance of the public interest in medicine and the public health and lays out the multiple reasons why it is necessary that the courts to apply a rebuttable presumption of public interest to deny injunctive relief in patent cases involving medically-related patents. Lastly, a set of hypothetical situations is offered to emphasize the necessity of the rebuttable presumption. Copyright © 2014 Lance Wyatt. J.D. Candidate, 2014, SMU Dedman School of Law; B.S.

No. 1] Rebuttable Presumption of Public Interest in Protecting the Public Health 299 I. INJUNCTIVE RELIEF IN PATENT INFRINGEMENT CASES PRIOR TO 2006 A. Injunctive Relief Overview The United States Constitution provides Congress with the enumerated power "to promote the progress of science and useful arts, by securing for limited times to ... inventors the exclusive right to their respective ... discoveries."1 Pursuant to this power, the Patent Act of 1952, as amended, governs patent law in the United States.2 A patent grants its holder the "right to exclude others from making, using, offering for sale, or selling the invention throughout the United States" for a certain amount of time.3 When this right to exclude is infringed upon, courts "may grant injunctions in accordance with the principles of equity to prevent the violation of any right secured by patent, on such terms as the court deems reasonable."4 Courts have traditionally established that a plaintiff seeking a permanent injunction must satisfy a four-factor test before being granted such relief.' These factors include: (1) that [the plaintiff] has suffered an irreparable injury; (2) that remedies available at law, such as monetary damages, are inadequate to compensate for that injury; (3) that, considering the balance of hardships between the plaintiff and defendant, a remedy in equity is warranted; and (4) that the public interest would not be disserved by a permanent injunction.6 However, not all courts have followed this four-factor test. B. Federal Circuit's "General Rule" The Federal Circuit Court of Appeals, established in 1982 and given exclusive patent appellate jurisdiction,' did not follow this traditional four-factor test prior to 2006.8 Instead, the Federal Circuit followed a "general rule that an injunction will issue when infringement has been adjudged, absent a sound reason for denying it."9 This "automatic injunction rule," or "general rule," arose U.S. CONST. art. I, § 8, cl. 8. 2 35 U.S.C. § 101 (2006); see Sue Ann Mota, eBay v.

Chicago-Kent Journal of Intellectual Property because the Federal Circuit would automatically apply a presumption of irreparable harm to patentees upon a finding of infringement.0 This presumption of irreparable harm was justified based upon the right to exclude granted by patents.11 Thus, successful plaintiffs were granted injunctions as a matter of course for over three decades.12 C. Public Health Exception While most successful patentees received permanent injunctions under the general rule, there was an exception to this rule.13 Prior to 2006, courts would deny an injunction "in order to protect the public interest."14 For example, in City of Milwaukee v. Activated Sludge, Inc., the Seventh Circuit denied permanent injunctive relief to protect the public health.15 While the defendant had infringed on the plaintiffs patented sewage treatment process, the court found that enforcing a permanent injunction would have closed the only sewage plant in the entire community.16 An injunction would have left the community without means to dispose of raw sewage other than running it into Lake Michigan and polluting the waters.1' Furthermore, such an order would have posed environmental and health risks to over half a million residents.18 The court concluded that: It is suggested that such harmful effect could be counteracted by chemical treatment of the sewage, but where, as here, the health and the lives of more than half a million people are involved, we think no risk should be taken, and we feel impelled to deny appellee's contention in this respect.19 Courts have also used the public interest exception to protect the public health when certain medically-related patents were involved.2 For example, in Vitamin Technologists v. Wisconsin Alumni Research Foundation, the defendant had infringed a patented process that produced vitamin D.21 This process 10 Davis, supra note 7, at 435-36. 11 See MercExchange, LLC v. eBay, Inc., 401 F.3d 1323, 1338 (Fed.

Cir. 1988); Datascope Corp. v. Kontron, Inc., 611 F. Supp. 889 (D. Mass. 1985), aff'd, 786 F.2d 398 (Fed. Cir. 1986); Vitamin Technologists v. Wis. Alumni Research Found., 146 F.2d 941 (9th Cir. 1944). 21 Vitamin Technologists, 146 F.2d at 942. [Vol. 13 No. 1] Rebuttable Presumption of Public Interest in Protecting the Public Health 301 contributed to the cure or amelioration of the disease, rickets.22 Even though these patents were found to be invalid, leaving the patentee without remedy, the court noted the public health implications of an injunction in dicta.23 While the patented process at issue could have been used to help cure rickets, a disease affecting the poor, the patentee withheld the practice of the patented process for this purpose.' The court noted "it is a public offense to withhold such processes from any of the principal foods of the rachitic poor"25 and concluded that such refusal warranted the denial of a permanent injunction.26 Further, in Datascope Corp. v. Kontron, Inc., the plaintiff alleged that the defendant had infringed its patented dual lumen heart catheter (IAB)27 and sought preliminary injunctive relief.28 Although preliminary injunctions and permanent injunctions differ in scope, the same traditional four factors are analyzed. 29 The defendant made a showing that it would be irreparably harmed by a preliminary injunction because it would suffer losses in sales, be forced to lay off employees, its good will would be injured, and it would have to write off inventory and capital improvements.30 More importantly, the defendant made a showing that the public interest would be harmed by a preliminary injunction because the record showed that “some physicians prefer defendant’s dual lumen IABs.” 31 Ultimately, the court denied the plaintiff’s request for injunctive relief with respect to the defendant’s dual lumen IABs.32 Additionally, some courts have modified permanent injunctions in medically-related patent infringement cases to allow for transition periods to accommodate the public interest.33 In Shiley, Inc. v. Bentley Labs., Inc., injunctive relief was granted against the defendant for the plaintiff’s patented bubble blood oxygenator.34 However, due to concerns of potential short-term supply problems from the sudden impact of the injunction, the court ordered that the injunction “contain a six-month transition period to allow an efficient and non-disruptive changeover for those institutions who now employ the [infringing device] exclusively.” 35 While the public interest exception was used to deny some medicallyrelated patent injunctions, most injunctions were still granted.36 The Federal Circuit’s “general rule” was abrogated, however, upon the Supreme Court’s holding in eBay Inc. v. MercExchange. 37
