Nos. 87-1206, 87-1211

United States Court of Appeals, Federal Circuit.

Before MARKEY, Chief Judge, BALDWIN, Senior Circuit Judge, and PAULINE NEWMAN, Circuit Judge.

MARKEY, Chief Judge.

DECISION

In No. 87-1206, E.I. DuPont de Nemours & Company (DuPont) appeals from those parts of a certified order of the United States District Court for the Southern District of Ohio, 654 F. Supp. 890, 1 USPQ2d 1833 (1987), finding that: (1) Mallinckrodt, Inc. (Mallinckrodt) had not infringed claims 1, 13, 14, 16, 18-20, 27 and 28 of United States Patent No. 4,082,840 ('840 patent) when it manufactured Technescan PYP (PYP) and sold it for use in blood pool imaging; (2) Mallinckrodt induced infringement, but did not directly infringe, those claims of the '840 patent when it manufactured PYP and sold it for use in bone scanning and cardiac imaging; and (3) Mallinckrodt had not willfully infringed claims 1, 7 and 10 of United States Patent No. 3,851,044 ('044 patent).1

In No. 87-1211, Mallinckrodt cross-appeals from those parts of the order which held: (4) the asserted '840 and '044 patent claims and claims 1, 5 and 19 of DuPont's United States Patent No. 4,016,249 ('249 patent) are valid; and (5) Mallinckrodt had not proved laches.2

The findings of noninfringement and nonwillfulness in the infringement of the '044 patent were clearly erroneous. The holdings in respect of validity and laches were correct.

OPINION

I. No. 87-1206

A. Infringement

Because the district court erroneously interpreted the asserted claims of the '840 patent, its findings that Mallinckrodt did not infringe those claims when it manufactured PYP and sold it for blood pool imaging, and did not directly infringe when it sold PYP for use in bone scanning and cardiac imaging, are clearly erroneous.

The record does not support the district court's determination that DuPont 'limited the claims of the patents in suit to99mTc-stannous-polyphosphate complexes formed in vitro.' 654 F. Supp. at 907, 1 USPQ2d at 1845. The asserted composition claims are drawn to no99mTc-stannous-polyphosphate complexes of any kind; they are drawn to stannous-phosphate complexes. Similarly, the asserted method claims are drawn to methods of preparing stannous-phosphate complexes, not99mTc-stannous-polyphosphate complexes.

The phrase 'for forming a complex with technetium-99m' in the preambles of independent composition claims 1, 27 and 28 is a statement of intended use, not a claim limitation. Loctite Corp. v. Ultraseal Ltd., 781 F.2d 861, 868, 228 USPQ 90, 94 (Fed. Cir. 1985). Infringement occurred when Mallinckrodt made the claimed composition, and when it performed the claimed methods of making that composition. 35 U.S.C. Secs. 154, 271(a) (patent excludes making, using, or selling). Whether the claimed stannous-phosphate complexes were sold for blood pool imaging, and whether99mTc-stannous-polyphosphate complexes actually form during blood pool imaging, are therefore irrelevant considerations in determining infringement of the asserted '840 claims.

It is improper for courts to read into a claim a limitation explicitly set forth in another claim. SRI Int'l v. Matsushita Elec. Corp., 775 F.2d 1107, 1122, 227 USPQ 577, 586 (Fed. Cir. 1985) (in banc). The district court committed further legal error, therefore, when it expressly read into claim 1 of the '840 patent the limitation of nonasserted claim 15 it interpreted as requiring that technetium-99m-stannous-polyphosphate complexes be formed in vitro only.

Mallinckrodt's argument that the specification and prosecution history of the '840 patent show an intent to limit the invention to use in bone scanning is without merit. The claims, not the specification, measure the invention, Environmental Designs, Ltd. v. Union Oil Co., 713 F.2d 693, 699, 218 USPQ 865, 871 (Fed. Cir. 1983), cert. denied, 464 U.S. 1043 (1984), and no reason appears in this case for limiting the claims in light of the specification. That the inventors did not in prosecuting their application foresee use of the claimed stannous-phosphate complexes in blood pool imaging is irrelevant to whether manufacture of the claimed complexes, for that or any other use, infringes the asserted claims. Inventors are entitled to the benefit of all uses to which their inventions can be put. E.g., Roberts v. Ryer, 91 U.S. 150, 157 (1875); B.G. Corp. v. Walter Kidde & Co., 79 F.2d 20, 22, 26 USPQ 288, 290 (2d Cir. 1935) (L. Hand, J.).

Mallinckrodt has not challenged the finding that it induced infringement of the asserted '840 claims when it sold PYP for bone scanning and cardiac imaging. The finding of inducement, rather than a finding of direct infringement, was based on the erroneous limitation of the claims to in vitro reconstitution of PYP. As above indicated, when Mallinckrodt made PYP it infringed the claims drawn to the composition and to the method of making it.

The finding that manufacture of PYP did not infringe the asserted '840 patent claims because it was sold for use in blood pool imaging is clearly erroneous and must be set aside. Anderson v. City of Bessemer City, N.C., 470 U.S. 564, 573 (1985); Fed. R. Civ. P. 52(a).3

B. Willfulness

Having made the unchallenged finding that Mallinckrodt infringed the '044 and '249 patents, the district court said it was exercising its 'discretion' in finding that infringement nonwillful, 654 F. Supp. at 909, 1 USPQ2d at 1846, and noted that Mallinckrodt did not copy the inventions, id. at 903, 1 USPQ2d at 1841.

A determination of willfulness or nonwillfulness is a distinct finding of fact, not an exercise of discretion, and is based on the totality of the circumstances. Kloster Speedsteel AB v. Crucible Inc., 793 F.2d 1565
