Opinion

ORDER

REVERCOMB, District Judge.

The plaintiff, a manufacturer of magnets, brought this suit to have the Court declare invalid certain important magnet patents granted to the defendant. The defendant counterclaimed for a declaratory *15 judgment and an injunction to prohibit infringement of its patents. The Court on July 28, 1989 heard oral argument on the defendant/counterclaimant’s motion for a preliminary injunction. Because the Court concludes that the equitable factors that must be considered in an application for a preliminary injunction weigh heavily in favor of the plaintiff/counterdefendant, the Court denies the motion.

I. The Facts

The patents of defendant/counterclaim-ant Sumitomo Special Metals Co. (“SSMC”) are for processes that it says have “revolutionized” magnet production. The processes enable manufacturers to produce magnets of unprecedented power at no more expense than that of previous state-of-the-art magnets, SSMC states. SSMC maintains that in the early 1980s it discovered a method of combining iron, boron, and various “rare earth” elements into magnets that are better than samarium-cobalt magnets, which previously had been the strongest magnets available. The iron, boron, and rare earth magnets have the added advantage of being made of elements that are more readily available than samarium or cobalt. .

The processes in SSMC’s patents involve “sintering,” a conventional technique by which the metals are reduced to a powder, compacted, and heated to a temperature just below the melting point, at which the physical and magnetic properties of the metals begin to change. SSMC’s Memo, at 3-5. SSMC’s discoveries, it maintains, include factors such as the proper mix of the metals, the temperature to which the powder must be heated, and the type of atmosphere needed for sintering. SSMC’s Memo, at 5-6. The first SSMC patent, issued on July 1, 1986, included all of these factors; later refinements and discoveries were the bases of additional patents.

SSMC manufactures its own magnets in Japan, but has chosen, as it may, to license the production rights to other companies. In the past few years nine large manufacturers — General Motors, Philips’ Gloeilampenfabrieken, IG Technologies, Vacuumschmelze, Krupp Widia, Aimants Ugimag, Shin-Etsu Chemical, TDK, and Hitachi Metals — each have signed contracts to pay SSMC for the right to produce and sell the patented magnets.

Plaintiff/counterdefendant Crucible Materials Corp. (“Crucible”) has not purchased the right to make magnets covered by SSMC’s patents, despite some negotiations between the two. Instead, Crucible chose to produce magnets that are admittedly covered by SSMC’s patents 1 and, with this suit, to challenge the validity of the patents in court. SSMC states that it has not taken action to enjoin Crucible from infringing on its patents during the past three years because (1) it was focusing its legal efforts on a dispute with General Motors concerning the patents and (2) it hoped to reach some sort of accomodation with Crucible. When Crucible filed this suit, SSMC counterclaimed to enjoin Crucible.

II. The Legal Standard

The standard for granting an injunction prohibiting patent infringement is no more stringent or lenient than that in other civil suits. H.H. Robertson Co. v. United Steel Deck, Inc., 820 F.2d 384, 387 (Fed.Cir.1987). Indeed, federal patent law explicitly provides broad equitable discretion for judges to “grant injunctions to prevent the violation of any right secured by patent, on such terms as the court deems reasonable.” 35 U.S.C. § 283. When a party applies for a preliminary injunction in a patent case, the Court should consider four factors: (1) whether the applicant has shown a reasonable likelihood of success on the merits; (2) whether it has shown that it will suffer irreparable harm without the injunction; (3) whether the balance of hardships tips in its favor; and (4) what effect an injunction would have on the public interest. See, e.g., Hy *16 britech Inc. v. Abbott Laboratories, 849 F.2d 1446, 1451 (Fed.Cir.1988).

III. Likelihood of Success on the Merits

The Court concludes that, at this stage in the litigation, SSMC has shown a reasonable likelihood of success on the merits.

Patents granted by the United States Patent and Trademark Office (“PTO”) are presumed valid until proven otherwise. 35 U.S.C. § 282. A challenger must prove invalidity by clear and convincing evidence. Ryco, Inc. v. Ag-Bag Corp., 857 F.2d 1418, 1423 (Fed.Cir.1988). Courts naturally must start with the presumption that the PTO, which holds expertise in the field, has made a reasonable decision in granting an exclusive right to use of an invention. See, e.g., American Hoist & Derrick Co. v. Sowa & Sons, Inc., 725 F.2d 1350, 1359 (Fed.Cir.), cert. denied, 469 U.S. 821, 105 S.Ct. 95, 83 L.Ed.2d 41 (1984).

The validity of SSMC’s patents is further bolstered by the fact that nine leading manufacturers, including General Motors and European and Japanese companies, have apparently acquiesced to SSMC’s patent and have agreed to pay SSMC for a license to make magnets covered by the patents. Such acquiescence is naturally strong evidence that industry experts view the patent as justifiable. See Eli Lilly and Co. v. Premo Pharmaceutical Laboratories, Inc., 630 F.2d 120, 136 n. 73 (3rd Cir.) (dictum), cert. denied, 449 U.S. 1014, 101 S.Ct. 573, 66 L.Ed.2d 473 (1980); Illinois Tool Works, Inc. v. Sweetheart Plastics, Inc., 436 F.2d 1180, 1187 (7th Cir.), cert. dismissed, 403 U.S. 942, 91 S.Ct. 2270, 29 L.Ed.2d 722 (1971).

Crucible argues that the patent will be declared invalid because the processes patented by SSMC fit into the “obviousness” exception in patent law, which prohibits patents from being issued to matter that “as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.” 35 U.S.C. § 103.
