     Before:  Randolph, Rogers, and Tatel, Circuit Judges.

     Opinion for the Court filed by Circuit Judge Randolph.

     Randolph, Circuit Judge:  "The active ingredients in most 
prescription drugs constitute less than 10% of the product;  
inactive 'excipients' (such as coatings, binders, and capsules) 
constitute the rest.  The term 'generic drug' is used to 
describe a product that contains the same active ingredients 
but not necessarily the same excipients as a so-called 'pioneer 
drug' that is marketed under a brand name."  United States 
v. Generix Drug Corp., 460 U.S. 453, 454-55 (1983).  New 
drugs, including new generic drugs, may not be marketed 
without the Food and Drug Administration's approval.  The 
Drug Price Competition and Patent Term Restoration Act of 
1984, Pub. L. No. 98-417, 98 Stat. 1585, revised the proce-
dures for obtaining the FDA's approval.  One of the provi-
sions in the "Hatch-Waxman Amendments," as this Act is 
known, conferred on the first generic drug applicant a 180-
day period during which it would be free of competition from 
generic applicants who file later.  The FDA implemented this 
provision through a regulation.  In Mova Pharmaceutical 
Corp. v. Shalala, 140 F.3d 1060 (D.C. Cir. 1998), we sustained 
a district court injunction against the FDA's enforcement of 
one of the regulation's requirements, finding it inconsistent 
with the statute.  In response to Mova, the FDA revised its 



system for granting the 180-day exclusivity period.  The 
questions in this case concern the validity of the revision.

                                      I


     In July 1998, the FDA tentatively approved Purepac Phar-
maceutical Company's application to market the generic drug 
ticlopidine hydrochloride, marketed by other companies under 
the brand-name "Ticlid."1  Although Purepac's application 
has become ready for final approval, the FDA is withholding 
action.  Purepac must, the FDA insists, wait until the first 
ticlopidine applicant--Torpharm, a division of Apotex, Inc.--
markets its product for 180 days.  At the time of this writing, 
it is not certain when these 180 days will start running.  The 
FDA has not yet finally approved Torpharm's application.

     With matters thus at a standstill, Purepac decided to take 
legal action. It sued for an injunction and a declaratory 
judgment, challenging the validity of the FDA's post-Mova 
revision and claiming that Torpharm was not entitled to the 
180-day exclusivity period because it had not been sued for 
patent infringement (a claim we will explain later in this 
opinion).  Other companies intervened on Purepac's side;  
Torpharm and the companies who market the brand-name 
drug intervened as defendants.2  The district court denied 
Purepac's motion for a preliminary injunction and this appeal 
followed.

                                      II


     Under the Hatch-Waxman Amendments, an applicant 
seeking to market a new drug--that is, a "pioneer appli-
cant"--must file a "New Drug Application."  See 21 U.S.C. 
s 355(a).  Among other things, the application must include 
full reports of investigations of the drug's safety and effec-
__________
     1 Ticlid is widely prescribed for patients who have a high risk of 
thrombotic strokes and who cannot tolerate aspirin.

     2 Invamed, Inc. and Teva Pharmaceuticals U.S.A., Inc. inter-
vened as plaintiffs;  Hoffman-LaRoche Inc. and Syntex (U.S.A.) 
Inc, in addition to Torpharm, intervened as defendants.

tiveness.  See 21 U.S.C. s 355(b)(1).  An applicant seeking to 
market a generic drug may submit an "Abbreviated New 
Drug Application."  As the name suggests, an abbreviated 
application is less demanding than a pioneer application;  it 
may, for instance, rely on the safety and effectiveness studies 
submitted by the pioneer applicant.  See 21 U.S.C. 
s 355(j)(2)(A)(i)-(v);  Mead Johnson Pharm. Group v. Bowen, 
838 F.2d 1332, 1333 (D.C. Cir. 1988).  An abbreviated applica-
tion also must include a certification that, for each of the 
patents applicable to the pioneer drug, the proposed generic 
drug would not infringe the patent because (I) the patent 
information has not been filed;  (II) the patent has expired; 
(III) the patent will expire on a stated date; or (IV) the 
patent is invalid or will not be infringed by the manufacture, 
use or sale of the drug for which the abbreviated application 
applicant seeks approval.  See 21 U.S.C. s 355(j)(2)(A)(vii)(I)-
(IV).

     Our concern is with IV, the method Torpharm and then 
Purepac used.  In a paragraph IV certification, the generic 
applicant must give notice to the owner of the patent, and to 
the holder of the approved application for the drug covered 
by the patent.  See 21 U.S.C. s 355(j)(2)(B)(i).  FDA approv-
al of the abbreviated application may be made "effective 
immediately," unless a patent infringement suit is brought 
against the applicant within forty-five days from the date the 
patent owner or application holder receives notice of the 
paragraph IV certification. See 21 U.S.C. s 355(j)(5)(B)(iii).

     No one brought a patent infringement suit against Torp-
harm (or Purepac) and it is therefore unnecessary to describe 
the provisions dealing with the various contingencies of such a 
lawsuit.  The section directly in dispute--the section confer-
ring the 180-day period of exclusivity--reads as follows:

          If the application contains a certification described in 
     subclause (IV) of paragraph (2)(A)(vii) and is for a drug 
     for which a previous application has been submitted 
     under this subsection continuing3 such a certification, the 

__________
     3 This should probably read "containing." See Mova Pharm. 
Corp., 140 F.3d at 1064 n.3.



     application shall be made effective not earlier than one 
     hundred and eighty days after-

          (I) the date the Secretary receives notice from the 
          applicant under the previous application of the first 
          commercial marketing of the drug under the previous 
          application, or

          (II) the date of a decision of a court in an action 
          described in clause (iii) holding the patent which is the 
          subject of the certification to be invalid or not infring-
          ed,

     whichever is earlier.

21 U.S.C. s 355(j)(5)(B)(iv), as amended by Pub. L. No. 
105-115, 111 Stat. 2296 (1997).

     The FDA's original regulation implementing this section, 
promulgated in 1994, provided:

     If an abbreviated new drug application contains a certifi-
     cation that a relevant patent is invalid, unenforceable or 
     will not be infringed and the application is for a generic 
     copy of the same listed drug for which one or more 
     substantially complete abbreviated new drug applications 
     were previously submitted containing a certification that 
     the same patent was invalid, unenforceable or would not 
     be infringed and the applicant submitting the first appli-
     cation has successfully defended against a suit for pat-
     ent infringement brought within 45 days of the patent 
     owner's receipt of notice submitted under s 314.95, ap-
     proval of the subsequent abbreviated new drug applica-
     tion will be made effective no sooner than 180 days from 
     whichever of the following dates is earlier:

     (i) The date the applicant submitting the first application 
     first commences commercial marketing of its drug prod-
     uct;  or

     (ii) The date of a decision of the court holding the 
     relevant patent invalid, unenforceable, or not infringed.
59 Fed. Reg. 50,338, 50,367 (1994) (emphasis added).  The 
italicized language embodied what the parties and our Mova 
opinion call the "successful defense" requirement:  the first 

generic applicant was entitled to the 180-day exclusivity 
period only after it had successfully defended a patent in-
fringement suit.

     Mova held that this portion of the regulation was "inconsis-
tent with the statutory text and structure."  140 F.3d at 
1076.4  As the court read the statute, it provided that a later 
generic applicant could not start marketing its product for 
180 days after either commercial marketing by the first 
applicant, or a court decision declaring the patent invalid or 
not infringed.  Id. at 1069.  The FDA's successful defense 
requirement read the commercial marketing "trigger" out of 
the statute.  As a result, first applicants who were not sued 
could never receive the benefit of the exclusivity period.  Id.

     After Mova, the FDA issued a "Guidance to Industry" 
announcing its intention to "formally" remove the successful 
defense requirement from the regulation and to conduct a 
rulemaking proceeding to issue new regulations under 
s 355(j)(5)(B)(iv).  In the meantime, the FDA said it would 
follow the statute as Mova interpreted it.  That is, the agency 
would inform "the first applicant to submit a substantially 
complete" abbreviated application, "with a paragraph IV cer-
tification," that the applicant was eligible for 180 days of 
market exclusivity even though it had not been sued for 
patent infringement.  The FDA added that it expected first 
applicants to begin marketing their product "promptly upon 
approval."

     In November 1998, while this case was pending, the FDA 
published an interim rule in the Federal Register amending 
its regulation to eliminate the successful defense requirement. 
The interim rule accomplished this by deleting from the 
regulation the following language, italicized above (21 C.F.R. 
s 314.107(c)(1)):  "and the applicant submitting the first appli-
cation has successfully defended against a suit for patent 
infringement brought within 45 days of the patent owner's

                                     III


     We come at last to Purepac's legal arguments.  In essence, 
Purepac maintains that the regulation containing the success-
ful defense requirement did not entitle Torpharm to the 180-
day exclusivity period because Torpharm had not been sued 
for patent infringement.  As Purepac sees it, even after Mova 
the FDA still had to require, as a condition for exclusivity, 
that the first generic applicant be sued for patent infringe-
ment, although the FDA could no longer insist that the 
applicant defend the suit successfully.

     The FDA's Guidance for Industry embraced a different 
interpretation of Mova and of the severability of the regula-
tion:  under the Guidance, a first applicant like Torpharm did 
not have to be sued in order to be entitled to the exclusivity 
period.  Purepac opposed the Guidance on a procedural 
ground, claiming that the FDA had gone beyond the mandate 
of Mova, and thereby effectively amended the regulation, 
something agencies may do only through notice and comment 
rulemaking, or through an interim rule.  The FDA's promul-
gation of an interim rule duplicating the Guidance puts an end 
to Purepac's arguments in this regard.

     In apparent anticipation of the FDA's issuing an interim 
rule (as the Guidance suggested it would), Purepac's brief 
also contended that the agency could not validly use this 
procedure because it would be unable to show "good cause" 
under 5 U.S.C. s 553(b)(B), a necessary condition for dispens-
ing with pre-promulgation notice and comment.  See Mid-
Tex Elec. Co-op., Inc. v. FERC, 822 F.2d 1123, 1131-33 (D.C. 
Cir. 1987).  The basis for this contention is basically the same 

__________
     5 The interim rule also amended 21 C.F.R. s 314.107(c)(4) by 
deleting the phrase "if sued for patent infringement." See 63 Fed. 
Reg. at 59,712. The original regulation had provided that the first 
applicant should notify the FDA of the date that it commenced 
commercial marketing, "if sued for patent infringement."  See 59 
Fed. Reg. at 50,368.


as Purepac's procedural challenge to the Guidance:  Mova did 
not strike down the regulation's requirement that the first 
applicant must defend a lawsuit before being eligible for the 
180-day exclusivity period;  the only portion of the regulation 
Mova rendered unenforceable was the requirement that the 
applicant "successfully" defend the lawsuit;  and because this 
so-called "lawsuit" requirement remained untouched by 
Mova, the FDA would have no grounds for claiming that it 
faced some pressing need, some good cause, to dispense with 
notice and comment before promulgating an amendment to 
the regulation.  Purepac also advanced the same line of 
reasoning to support its position that the FDA's response to 
Mova was irrational and inconsistent with s 355(j)(5)(B)(iv).

     We see the FDA's revised system for granting exclusivity 
as consistent with the statute and with our Mova decision.  
Section 355(j)(5)(B)(iv) does not, on its face, require the first 
applicant to be sued in order to benefit from market exclusivi-
ty.  It provides, as we said in Mova, that the 180-day 
exclusivity period for the first applicant begins running upon 
the occurrence of one of two events, whichever is earlier--
commercial marketing by the first applicant, or a court 
decision in favor of the applicant.  140 F.3d at 1069.  The 
second condition obviously presupposes a lawsuit.  The first 
does not.  The words of the statute provide no reason to 
think, as Purepac must, that the only "commercial marketing" 
contemplated in s 355(j)(5)(B)(iv) is marketing that takes 
place while the first applicant is defending a lawsuit or after 
the lawsuit has concluded.  The regulation, as it now stands, 
is fully consistent with the statute.  By removing the lan-
guage embodying the successful defense requirement, the 
FDA eliminated a significant difference between its regula-
tion and s 355(j)(5)(B)(iv).

     Agencies occasionally promulgate a regulation merely du-
plicating the underlying statute.  As matters stand after the 
FDA's revisions, its regulation is of that type.  There is 
nothing irrational in the FDA's giving first applicants the 
180-day exclusivity period even if they have not been sued.  
On its face, the statute does the same.  Seen in this light, 



Purepac's real objection is to the words Congress used, not 
the FDA's revision of its regulation.

     Purepac points out that in the preamble to the final rule 
containing the successful defense requirement, the FDA stat-
ed that the statute--s 355(j)(5)(B)(iv)--"can be applied 
straightforwardly only when the applicant who seeks the 180-
day period of exclusive marketing has been involved in a 
patent infringement lawsuit."  59 Fed. Reg. at 50,353.  
Whether this and other remarks in the preamble were intend-
ed to convey the idea that the statute should be read to 
require a lawsuit against the first applicant, although not a 
successful defense of the lawsuit, is uncertain and, in any 
event, beside the point.  The FDA's current position is that, 
as a temporary measure pending a rulemaking proceeding, it 
will not infer requirements for exclusivity that are not in the 
statutory text.  Its explanation for this position is more than 
adequate:  the decision in Mova forced it to go back to the 
drawing board.

     Purepac also offers a policy reason for reading a lawsuit 
requirement into s 355(j)(5)(B)(iv).  If a first applicant is 
never sued for patent infringement, it is possible that neither 
of two "triggers" for the running of the 180 days of market 
exclusivity--commercial marketing or a judicial decision--
would ever occur.  Without a lawsuit there would be no 
judicial decision.  If the applicant never begins marketing its 
product, the 180 days would never run and all later generic 
applicants would be barred from bringing their products to 
market.  Purepac's point is hardly new.  Mova discussed it at 
some length, 140 F.3d at 1067, said in dictum that a lawsuit 
requirement "would have corrected the problem," id. at 1071,6 

__________
     6 It is not clear that the "problem" would be entirely solved. 
Suppose, as Purepac proposes, only the word "successfully" were 
eliminated from the regulation, thus retaining as a condition to 
receiving exclusivity that the first applicant "has successfully de-
fended against a suit for patent infringement brought within 45 
days of the patent owner's receipt of notice."  Suppose further that 
a first applicant is sued but that the suit does not result in a judicial 
decision finding the patent not infringed or invalid, so that the 



and then cautioned that "Congress may have intended to 
reward the first ... applicant for his enterprise whether or 
not he is later sued," thus suggesting that a lawsuit require-
ment might be inconsistent with congressional intent. See id. 
at 1071 n.11.  For this reason, Mova described a narrower 
answer to the problem:  for first applicants who are not sued, 
they must bring their products to market within a prescribed 
period in order to benefit from exclusivity.  See id.  There is 
some indication that the FDA will consider this alternative in 
the rulemaking promised in its Guidance, or in response to 
comments on its interim rule.7  That is the proper time and 
setting for Purepac to repeat its point and to offer its 
solution.  In the meantime, the FDA has implemented an 
interim measure, basically duplicating the statute.  The 
FDA's action, pursuant to which it is withholding final ap-
proval of Purepac's generic application pending Torpharm's 
commercial marketing, is not irrational, it is not inconsistent 
with s 355(j)(5)(B)(iv) and it is not contrary to the mandate in 
Mova.

     The district court's judgment denying the motion for a 
preliminary injunction is therefore affirmed.

     So ordered.


__________
judicial decision trigger in s 355(j)(5)(B)(iv) is not activated.  This 
could happen if, for instance, the suit is dropped or settled.  In 
those events, only commercial marketing could trigger the running 
of the 180-day period.  And the same problem Purepac identifies 
would exist if the first applicant fails to market its product.

     7 The Guidance stated that first applicants who are not sued will 
receive a letter from the FDA telling them that they will neverthe-
less receive the benefit of exclusivity, but warning that the agency 
"expects that you will begin commercial marketing of your product 
promptly upon approval."
