ANTARES PHARMA, INC., Plaintiff-Appellant, v. MEDAC PHARMA INC. and Medac GmbH, Defendants-Appellees.
No. 2014-1648.
United States Court of Appeals, Federal Circuit.
Nov. 17, 2014.
771 F.3d 1354
Azure cannot have it both ways. If the term “MAC address” is properly construed to refer only to addresses assigned to peripheral devices by a hub device, then the accused products do not infringe. If, on the other hand, the term is broadly and unreasonably expanded to cover addresses assigned at the time of manufacture, then the asserted claims are invalid. See MagSil, 687 F.3d at 1381 (“[A] patentee chooses broad claim language at the peril of losing any claim that cannot be enabled across its full scope of coverage.“); Liebel-Flarsheim Co. v. Medrad, Inc., 481 F.3d 1371, 1380 (Fed.Cir.2007) (“The irony of this situation is that [the patentee] successfully pressed to have its claims include a jacketless system, but, having won that battle, it then had to show that such a claim was fully enabled, a challenge it could not meet.“).

Before DYK, REYNA, and TARANTO, Circuit Judges.
DYK, Circuit Judge.
Plaintiff-Appellant Antares Pharma, Inc. (“Antares“) appeals from a decision of the United States District Court for the District of Delaware denying Antares’ motion for preliminary injunction. Antares seeks to enjoin alleged infringement of claims 31, 34, 35, and 37 of a reissue patent, RE44,846 (“the ‘846 patent“). Because we hold that these reissue claims are invalid for failure to comply with the “original patent” requirement of
BACKGROUND
I
Antares is a developer of automatic injection devices used to self-administer
On June 22, 2012, roughly 22 months after the ‘015 patent issued, Antares sought a reissue for the patent pursuant to
The ‘846 reissue patent was granted on April 15, 2014. The specification and claims 1-22 were left unaltered; claims 23-37 were added. The originally allowed claims recite various embodiments of a jet injection device and specify, for example, the exact depth the needle assist plunges to, the force at which the medicant is expelled, and the gauge of the needle. The reissue claims (claims 23-37) cover embodiments of injection devices (not restricted to jet-injection devices) with particular combinations of safety features. Claim 31, for example, covers certain injectors containing at least a latch, pushbutton, and needle guard. By Antares’ own admission, the reissue claims recite a different invention from what was originally claimed. See Appellant Br. 14-15 (“These are two different inventions.... [Original c]laim 1 is directed to ‘jet injection device’ performance.... [Reissue c]laim 31, on the other hand, is directed to safety features for any ‘injection device.‘“) (emphasis in original).

Defendants medac Pharma, Inc. and medac GmbH (collectively, “Medac“) manufacture and sell pre-filled, hand-powered methotrexate syringes. On September 10, 2013, Medac submitted a 505(b)(2) new drug application (“NDA“) with the FDA for their pre-filled methotrexate syringes, which they intend to sell under the trade name RASUVO. Antares does not accuse the methotrexate medication itself of infringing any patents; rather, Antares accuses the injection device housing the methotrexate of infringing various claims. Because the product prospectively sold under the application would allegedly infringe claims of the ‘846 patent, the filing of the application constitutes an act of artificial infringement under
Antares filed suit against Medac in the District of Delaware on February 28, 2014, initially alleging infringement of certain patents not involved in the present appeal based on Medac‘s filing of the 505(b)(2) NDA. On March 14, 2014, Antares filed a motion for preliminary injunction. On April 18, 2014, Antares filed an amended complaint, adding the ‘846 patent to the list of patents it was asserting against Medac, and amended the motion for preliminary injunction accordingly, asserting
On May 5, 2014, Medac counterclaimed for invalidity and non-infringement of the patents-in-suit. On May 28, 2014, Medac filed its opposition to the motion for preliminary injunction, arguing that the asserted reissue claims of the ‘846 patent were invalid for violating the recapture rule and failing the original patent requirement of
On July 10, 2014, the district court denied the motion for preliminary injunction, finding that Antares failed to carry its burden of showing a likelihood of success on the merits with respect to the ‘846 patent because claims 31, 34, 35, and 37, added during reissue, are likely invalid for violating the recapture rule. The court found that, during the original prosecution, the applicants repeatedly distinguished the prior art by focusing on the fact that the claims were limited to jet injectors. During reissue, when the applicants sought to claim safety features not limited to jet injectors, they were broadening their claims to cover non-jet injectors. Because the court held that the recapture rule was violated, it did not consider the question of whether the original patent requirement was satisfied. The court held that Antares would likely suffer irreparable harm and that the balance of interests was in equipoise.
Antares appealed the denial of the preliminary injunction with respect to the asserted claims of the ‘846 patent. We have jurisdiction pursuant to
DISCUSSION
I
Antares argues that the district court incorrectly applied the recapture rule and that, under the “overlooked aspects” cases, the recapture rule is inapplicable. In this respect, Antares relies on Mostafazadeh, 643 F.3d at 1360. Antares argues that, while the recapture rule generally prohibits a patentee from “regain[ing] through reissue the subject matter that he surrendered in an effort to obtain allowance of the original claims,” the recapture rule is entirely inapplicable if the reissue claims recite “overlooked aspects” of the invention. Mostafazadeh, 643 F.3d at 1358 (quoting In re Clement, 131 F.3d 1464, 1468 (Fed.Cir.1997)); see also In re Youman, 679 F.3d 1335, 1347 (Fed.Cir.2012). Antares argues that overlooked aspects are “patentably distinct (1) inventions; (2) embodiments; or (3) species not originally claimed[,] not mere incidental features of the originally-claimed invention.” Mostafazadeh, 643 F.3d at 1360 (citation omitted).1 Because we hold that the asserted claims of the ‘846 patent fail the original patent requirement of

The original patent requirement is well-established, being recognized in the reissue statute and longstanding Supreme Court jurisprudence. The current statute governing reissues provides in relevant part:
Whenever any patent is, through error ..., deemed wholly or partly inoperative or invalid ... by reason of the patentee claiming more or less than he had a right to claim in the patent, the Director shall ... reissue the patent for the invention disclosed in the original patent....
Supreme Court cases have recognized this requirement for more than 150 years.4
The Supreme Court‘s definitive explanation of the original patent requirement appears in U.S. Industrial Chemicals, Inc. v. Carbide & Carbon Chemicals Corp., 315 U.S. 668, 62 S.Ct. 839, 86 L.Ed. 1105 (1942). There, the Court analyzed a reissue patent relating to a process for the production of a chemical compound. The original claims required the presence of water as a catalyst. After the patent was issued, it became clear that water was not required as a catalyst. The patentee asserted that the original claim was in error because it required the presence of water, and the patentee sought and obtained a reissue that omitted that “erroneous” requirement. The patentee subsequently brought suit for infringement of the newly added claims, which omitted the water limitation. Id. at 670-75, 62 S.Ct. 839. The Court held the reissue claims invalid for failing to satisfy the “same invention” requirement. Id. at 680-81, 62 S.Ct. 839. It explained that a reissue claim is for the “same invention” if the original patent specification fully describes the claimed inventions, but not if the broader claims “are [ ] merely suggested or indicated in the original specification.” Id. at 676, 62 S.Ct. 839. “[I]t is not enough that an invention might have been claimed in the original patent because it was suggested or indicated in the specification.” Id. The reissue claims were invalid because, although the original specification hinted at the fact that water might be optional (see id. at 672, 62 S.Ct. 839 (“Water can be admitted in the reaction vessel....“)), it was nonetheless clear that the invention disclosed in the original patent required the presence of water. Id. at 676-78, 62 S.Ct. 839. That hint, suggestion, or indication that water was optional was not enough to save the reissue claims. Id. Circuit cases immediately following Industrial Chemicals adopted the same test.6
Whenever any patent is wholly or partly inoperative or invalid ... the commissioner shall ... cause a patent for the same invention ... to be reissued to the patentee....
35 U.S.C. § 64 (1946) (emphasis added).
The 1952 Amendments changed the language from “the same invention” to “the original patent,” so that the provision reads: “[w]henever any patent is, through error ..., deemed wholly or partly inoperative or invalid ... the Director shall ... reissue the patent for the invention disclosed in the original patent....” Id.
Despite the change in language relating to the “same invention” requirement, it appears that no change in substance was intended. There is nothing in the statutory language or legislative history suggesting that Congress intended to overturn the long line of Supreme Court cases culminating in Industrial Chemicals by this change in language. As explained in P.J. Federico, Commentary on the New Patent Act, reprinted in 75 J. Pat. & Trademark Off. Soc‘y 161, 205 (1993):
While the old statute stated that the patent is reissued “for the same invention,” the new statute states that the patent is reissued “for the invention disclosed in the original patent.” Here, again, there is no indication in the printed record that any change was intended, although a slight broadening effect has been argued.7
So too, in Warner-Jenkinson Co. v. Hilton Davis Chemical, 520 U.S. 17, 117 S.Ct. 1040, 137 L.Ed.2d 146 (1997), although not directly addressing the “same invention” requirement, the Supreme Court explained that “[t]he 1952 Patent Act is not materially different from the 1870 Act with regard to claiming, reissue, and the role of the PTO,” and that “[s]uch minor differences as exist between those provisions in the 1870 and the 1952 Acts have no bearing on [our precedent] and thus provide no basis for our overruling it.” Id. at 26, 117 S.Ct. 1040.
After the 1952 Amendments, the circuit courts and our predecessor court continued to view Industrial Chemicals as articulating the applicable test, irrespective of the passage of the 1952 Amendments. See, e.g., Bolkcom v. Carborundum Co., 523 F.2d 492, 502 (6th Cir.1975); McCullough Tool Co. v. Well Surveys, Inc., 343 F.2d 381, 389 (10th Cir.1965); Riley v. Broadway-Hale Stores, Inc., 217 F.2d 530, 531 (9th Cir.1954); In re Rowand, 526 F.2d 558, 559-60 (CCPA 1975).
Thus, for example, in McCullough, the Tenth Circuit held a reissue patent valid over an invalidity challenge. Referencing Industrial Chemicals, the court stated that “[t]he original and reissue patents are for the same invention where the latter
Similarly, in Riley v. Broadway-Hale Stores, Inc., 217 F.2d 530, 531 (9th Cir. 1954), the court held that a single, vague reference in the original specification to shoulder pads without gaps in the padding did not adequately support the reissue claims, which claimed shoulder pads without gaps, when the original claims only claimed shoulder pads with gaps, and the specification described the gapped shoulder pads as an “essential feature” of the invention. Riley, 217 F.2d at 532. As the court explained, “[t]he broader claims of the reissue must be more than merely suggested or indicated in the original patent.” Id. “[I]t is not enough that an invention might have been claimed in the original invention because it was suggested or indicated in the specification.” Id. (quoting Indus. Chems., 315 U.S. 668, 675-76, 62 S.Ct. 839, 86 L.Ed. 904 (1942)).
Finally, in In re Rowand, our predecessor court rejected a reissue claim seeking coverage of a particular method for making Teflon tubing when the specification focused on describing the product itself. 526 F.2d at 560. The court held that a single, vague statement in the specification broadly summarizing the general method for making Teflon tubing did not adequately disclose the particular method claimed on reissue. Id. Citing to Industrial Chemicals, the court held that the invention claimed on reissue was not sufficiently disclosed and failed under
Since the creation of this court in 1982, we have addressed Industrial Chemicals and the original patent requirement on four occasions: In re Hounsfield, 699 F.2d 1320 (Fed.Cir.1983); In re Weiler, 790 F.2d 1576 (Fed. Cir.1986); In re Amos, 953 F.2d 613 (Fed.Cir.1991); and Hester Industries., Inc. v. Stein, Inc., 142 F.3d 1472 (Fed.Cir.1998). Significantly, none of those cases suggested that the 1952 change in language worked a substantive change in the “same invention” requirement or that the standard of Industrial Chemicals has in any way been altered by the legislative changes. Hester Industries simply noted there was a change in the statutory language and that “the essential inquiry under the ‘original patent’ clause of
Our cases shed light on Industrial Chemicals in two respects. First, they rejected a gloss put on Industrial Chemicals by the Board in later cases, which had interpreted Industrial Chemicals, Rowand, and In re Mead, 581 F.2d 251 (CCPA 1978) as creating an “intent to claim” test for the original patent requirement. In Hounsfield, we reversed the
IV
Applying the Industrial Chemicals standard, asserted reissue claims 31, 34, 35, and 37 are invalid. The original claims are significantly different in scope and coverage than the asserted claims. Claims 1-22 are focused on jet injectors, and every one of those claims contains the “jet injection” limitation. The asserted claims are focused on particular safety features and do not contain the jet injection limitation. Indeed, appellants themselves argue that the asserted reissue claims cover a different invention than that originally claimed. To be sure, the original patent requirement focuses on the original specification rather than the original claims. While the claims may be used to determine whether the written description requirement has been satisfied outside of the reissue context, Ariad, 598 F.3d at 1347, by definition in reissue the original claims do not disclose the invention claimed on reissue. Thus, we must look to the specification. The original specification here does not adequately disclose the later-claimed safety features to meet the Industrial Chemicals standard. The specification discussed only one invention: a particular class of jet injectors. This is clear from the title of the patent (“Needle Assisted Jet Injector“), the abstract (“A jet injection device...“), the summary of the in-
Although safety features were mentioned in the specification, they were never described separately from the jet injector, nor were the particular combinations of safety features claimed on reissue ever disclosed in the specification. Rather, the safety features were serially mentioned as part of the broader conversation: how to build the patented jet injection device. For example, Antares, in its briefing, emphasizes the “push button” safety feature claimed in the reissue. But, a “push button” is mentioned in only one passage in the specification: “Alternatively, a push button could be located at the proximal end of the device and be locked in an idle position. The movement of the needle guard could unlock the push button and allow the user to depress it and consequently fire the device.” Id. col. 12 ll. 9-13. These “suggest[ions]” or “indicat[ions]” of alternative inventions are not sufficient to satisfy the original patent requirement of
The situation here is quite unlike Amos, in which we held that the original patent requirement was satisfied. In Amos, the patentee sought to broaden his claims on an invention relating to the use of rollers to hold down work-pieces on a moving table. The specification expressly disclosed that rollers, as they approached the end of the table, could be “raised either mechanically by the roller cams or electronically by the computer controlling the router.” Amos, 953 F.2d at 614. The original claims only covered the manual embodiment. On reissue, the applicant sought to add the computer-controlled embodiment. Id. The Board denied the reissue because there was no objective intent to claim. Id. at 615. This court reversed the Board because the exact embodiment claimed on reissue was expressly disclosed in the specification. Id. at 617-19. Such an express disclosure is exactly what was missing here.
CONCLUSION
The claims on appeal are invalid for failure to satisfy the original patent requirement of
