Opinion

REVISED OPINION

McKELVIE, District Judge.

This is a patent case. The Johns Hopkins University is a Maryland non-profit corporation with its principal place of business in Baltimore, Maryland. Johns Hopkins owns U.S. Patent Nos. 4,714,680 (the ’680 patent) and 4,965,204 (the ’204 patent). These patents are known collectively as the Civin patents, named after their inventor, Dr. Curt Civin, a physician and professor at The Johns Hopkins University School of Medicine and The Johns Hopkins University Hospital in Baltimore, Maryland. The patents disclose a method to prepare purified suspensions of human stem cells through the use of specific antibodies for therapeutic use in transplantation and other procedures.

Johns Hopkins granted an exclusive license to use the Civin patents to Becton, Dickinson and Company, a New Jersey Corporation with its principal place of business in Franklin Lakes, New Jersey. Becton Dickinson thereafter granted an exclusive license to Baxter Healthcare Corporation, which in turn conveyed its rights under the Civin patents to Nexell Therapeutics, Inc., a Delaware corporation with its principal place of business in Irvine, California.

Nexell produces the Isolex system, a magnetic cell separation device. When used in conjunction with the antibodies *409 identified in the Civin patents, this product can separate stem cells from peripheral blood cells and bone marrow for transplantation and other therapeutic uses. This device has been approved by the Food and Drug Administration (FDA) for commercial sale in the United States.

Defendant AmCell Corporation is a Delaware corporation with its principal place of business in Sunnyvale, California. Defendant Miltenyi Biotec, Inc. is a California corporation with its principal place of business in Auburn, California. Defendant Miltenyi Biotec GmbH is a German corporation with its principal place of business in Germany.

Miltenyi Biotec GmbH developed MACS, a magnetic cells separating technology. Based on MACS, AmCell produces CliniMACS, a device which permits large-scale magnetic cell separation. Mil-tenyi Biotec GmbH holds a license from Becton Dickinson to use the antibodies in the Civin patents for in vitro research. The license agreement excludes the use of the antibodies for in vivo therapeutic research.

On March 1, 2000, Nexell, Becton Dick-enson, and Johns Hopkins filed a complaint against AmCell, Miltenyi Biotec, Inc., and Miltenyi Biotec GmbH alleging that by selling or offering to sell the Clini-MACS device for use with certain antibodies, defendants infringed or actively induced others to infringe the Civin patents, breached the license agreement, and engaged in unfair competition.

On April 24, 2000, Miltenyi Biotec, Inc. and Miltenyi Biotec GmbH moved to dismiss the complaint pursuant to Fed. R.Civ.P. 12(b)(2) on the ground that this court lacks personal jurisdiction over them and under Fed.R.Civ.P. 12(b)(4) and (5) for insufficient process and insufficient service of process. The same day, AmCell answered the complaint and counterclaimed that Nexell, Becton Dickinson, and Johns Hopkins engaged in unfair competition and moved for a declaratory judgment that AmCell did not infringe the Civin patents or breach the license agreement. Because of ongoing jurisdictional discovery, the plaintiffs have not responded to the motions to dismiss. On May 16, 2000, plaintiffs replied to AmCell’s counterclaims.

On November 8, 2000, AmCell moved for a summary judgment of non-infringement. On December 18, 2000, Nexell, Becton Dickinson, and Johns Hopkins moved for a partial summary judgment of infringement against AmCell, Miltenyi Bio-tec, Inc., and Miltenyi Biotec GmbH. Sections 271(a), (b), and (c) of the patent statute set out grounds for liability for infringement, active inducement to infringe, and contributory infringement. Section 271(e)(1) lays out an exemption from infringement for activities related to obtaining regulatory approval. Plaintiffs claim that defendants infringe under §§ 271(a), (b), and (c) and that defendants’ actions are not protected by the exemption in § 271(e)(1). AmCell claims that it does not infringe the Civin patents under 35 U.S.C. § 271(e)(1) because it is pursuing approval from the FDA for use of the CliniMACS device in conjunction with antibodies covered by the Civin patents.

The court heard oral arguments on these motions on January 31, 2001. This is the court’s decision on those motions.

I. FACTUAL BACKGROUND

The court draws the following facts from the pleadings in this case; the affidavits, transcripts of depositions, and answers to interrogatories offered by the parties in support of and in opposition to the pending motions; and the court’s previous opinion construing the claims of the Civin patents, see Johns Hopkins Univ. v. CellPro, 931 *410 F.Supp. 303 (D.Del.1996) aff'd in relevant part, 152 F.3d 1342 (Fed.Cir.1998).

A. The Technology

The Civin patents pertain to pure suspensions of immature blood cells, known as stem cells, and the monoclonal antibodies used to produce the suspensions. Stem cells are a vital part of bone marrow and can develop into many different forms of mature blood cells. Blood consists of plasma, a liquid that makes the blood fluid and that contains proteins for clotting, and certain blood cells — red cells, platelets, and white cells. Red cells carry oxygen in the blood. Plateletes cause blood to clot. White cells help fight infections and are part of the immune system. White blood cells are further divided into two large families: lymphocytes and granulocytes. There are different types of lymphocytes such as T lymphocytes, also known as T cells, and B lymphocytes, also known as B cells. T cells govern certain immune responses and are the cells that are destroyed by the AIDS virus. B cells make antibodies, which are important for fighting certain types of infections.

Blood cells have a short life span, and thus the body must produce millions of blood cells each day. Blood cells are manufactured in the cavity of some bones in a tissue known as bone marrow. Some cells, known as pluripotent or multipotent stem cells, exist in bone marrow and can create a number of different types of cells. A stem cell produces other cells by dividing over and over until thousands of cells have been manufactured.

Stem cells are called immature because they have not determined what type of cell they will become. A stem cell may become a lymphoid stem cell that can later become a B or T cell. Alternatively, a stem cell can become a myeloid stem cell that can later become a red cell, a platelet, or a granulocyte. Stem cells are very rare and difficult to locate. Over time, stem cells become progressively more “differentiated,” which is the word used to describe blood cell maturation.
