DECIDED: March 29, 2007

Before MICHEL, Chief Judge, LOURIE and BRYSON, Circuit Judges. 

MICHEL, Chief Judge. 

Citizen Electronics Company, Ltd. (“CE”) appeals from a final order of the United 

States District Court for the District of Columbia dismissing its declaratory judgment 

(“DJ”) complaint against OSRAM GmBH and OSRAM OPTO Semiconductors GmBH 

(collectively, “OSRAM”) for lack of subject matter jurisdiction. Citizen Elecs. Co. v. 

OSRAM GmBH, No. 05-1560 (D.D.C. Dec. 20, 2005) (“Citizen II”). The district court 

held that CE’s DJ complaint was barred under the doctrine of res judicata because CE 

had already litigated the issue of subject matter jurisdiction in Citizen Electronics Co. v. 
OSRAM GmBH, 377 F. Supp. 2d 149 (D.D.C. 2005) (“Citizen I”). Because the district 

court correctly determined that it lacked subject matter jurisdiction over CE’s DJ 

complaint, we affirm. 

INTRODUCTION 

CE and OSRAM are competitors in the field of white light emitting diode (“white 

LED”) technology. OSRAM is the owner or assignee of U.S. Patent Nos. 6,066,861, 

6,245,259, 6,277,301, 6,576,930, 6,592,780, 6,613,247, and 6,812,500, all directed to 

white LED technology. On January 18, 2005, CE filed an action against OSRAM for a 

declaratory judgment that its white LEDs did not infringe upon OSRAM’s patents, or that 

the patents were invalid. 

On April 27, 2005, OSRAM filed a motion to dismiss the DJ action under Fed. R. 

Civ. P. 12(b)(1) for lack of subject matter jurisdiction. In its motion, OSRAM stated that 

“[i]n response to Citizen’s provoking a fight by filing this surprise declaratory judgment 

action, OSRAM has taken action to protect its patent rights in Europe.” Specifically, on 

March 14, 2005, OSRAM filed a patent infringement case against CE in Germany on 

related foreign patents directed to white LED technology. On July 14, 2005, the district 

court ruled in favor of OSRAM, dismissing CE’s DJ action. Citizen I, 377 F. Supp. 2d at 

157. The district court held that CE failed to prove that there was an “actual 

controversy” under the Declaratory Judgment Act, 28 U.S.C. § 2201(a), on January 18, 

2005, the time the suit was filed. While noting that OSRAM had filed suit in Germany 

against CE, the district court nonetheless found it to be irrelevant since this event 

occurred after the filing of CE’s complaint. Citizen I, 377 F. Supp. 2d at 155 n.7. CE did 

not appeal the district court’s decision. 

2006-1211 2
On August 2, 2005, CE filed a second DJ action against OSRAM.1

 To support its 

allegation of an “actual controversy,” CE reiterated the events allegedly leading to an 

“actual controversy” in its first complaint and listed the following “new” facts for 

consideration by the district court: (1) that on May 2, 2005, OSRAM issued a report on 

its website describing the action against CE in Germany; and (2) also on May 2, 2005, 

OSRAM issued a press release mentioning action taken by OSRAM in the International 

Trade Commission pursuant to Section 337 of the Tariff Act of 1940 seeking to exclude 

from entry into the U.S. certain white LEDs manufactured, imported, or sold by another 

company, Dominant Semiconductors, and stating, “Our objective in taking legal action 

against Citizen and issuing warnings to Dominant is to prevent unauthorized use of our 

technology.” 

In response to the second DJ complaint, OSRAM again filed a motion to dismiss 

for lack of subject matter jurisdiction, arguing that the new facts in the second complaint 

were barred from consideration by the district court under the principles of res judicata. 

CE filed an amended complaint on November 11, 2005, adding the fact that OSRAM’s 

German complaint was formally served on CE under the Hague Convention on 

September 28, 2005. 

On December 20, 2005, the district court ruled in favor of OSRAM and dismissed 

CE’s second DJ action. In its opinion, the district court first acknowledged that the case 

presented a “novel issue of whether jurisdictional facts that occurred after plaintiff filed 

its first suit but prior to the Court’s dismissal of that suit may be relied on in a second 

suit to cure the jurisdictional defect.” Citizen II, slip op. at 3. Relying on the decisions

 CE’s second DJ action did not include U.S. Patent No. 6,812,500. 

2006-1211 3
made by the Court of Appeals for the District of Columbia Circuit in Dozier v. Ford Motor 

Co., 702 F.2d 1189, 1191 (D.C. Cir. 1983) and GAF Corp. v. United States, 818 F.2d 

901, 912-13 (D.C. Cir. 1987), the district court held that CE was estopped under the 

doctrine of res judicata from relying on events prior to July 14, 2005—the dismissal date 

of CE’s first DJ action—as evidence of an “actual controversy.” Since the district court 

refused to consider any facts known prior to its dismissal of the first DJ action, the only 

event that it considered with regard to the second DJ action was service of process, 

which the court found to be insufficient to cure the jurisdictional defect. Citizen II, slip 

op. at 8. 

This appeal followed. This court has jurisdiction pursuant to 28 U.S.C. 

§ 1295(a)(1). 

DISCUSSION 

We review a district court’s application of res judicata de novo, Shell Petroleum, 

Inc. v. United States, 319 F.3d 1334, 1338 (Fed. Cir. 2003), but apply the law of the 

pertinent regional circuit. Epic Metals Corp. v. H.H. Robertson Co., 870 F.2d 1574, 

1576 (Fed. Cir. 1989). 

It is well settled that the principles of res judicata2 apply to questions of 

jurisdiction as well as to other issues. American Sur. Co. v. Baldwin, 287 U.S. 156, 166 

(1932); see also Underwriters Nat’l Assurance Co. v. N. C. Life & Accident & Health Ins.

Guar. Ass’n, 455 U.S. 691, 706 (1982). In the District of Columbia Circuit, a prior 

dismissal for lack of subject matter jurisdiction precludes relitigation of the same 

 2

 The parties agree that res judicata is an umbrella term covering two types 

of preclusive effects of judgments: claim preclusion and issue preclusion. The type of 

res judicata invoked by the district court here is issue preclusion. 

2006-1211 4
jurisdictional issue in a later suit, unless the doctrine of “curable pleading defects” 

applies. Dozier, 702 F.2d at 1191. “The ‘curable defect’ exception applies where a 

‘precondition requisite’ to the court’s proceeding with the original suit was not alleged or 

proven, and is supplied in the second suit—for example, the Government’s filing of an 

affidavit of good cause in a denaturalization proceeding, proper service of process, or 

residency adequate to invoke diversity jurisdiction.” Id. at 1192 (internal citations 

omitted). Here, CE alleges that the events subsequent to its January 18, 2005 filing 

date, i.e., OSRAM’s filing of a patent infringement suit against CE in Germany on March 

14, 2005, OSRAM’s website report and press release of May 2, 2005, and service of 

process on September 28, 2005, cure any jurisdictional defect that CE may have had in 

its first DJ action. In contrast, OSRAM argues that CE is estopped from relying in the 

second DJ complaint on events that occurred before dismissal of CE’s first DJ action on 

July 14, 2005 as supporting an allegation of an “actual controversy.” 

Although CE contends on appeal that Federal Circuit law applies, its argument 

on this point is precluded by its agreement below that D.C. Circuit law applies. Under 

D.C. Circuit law, the “curable defect” doctrine is limited to events that occur after the 

original dismissal for lack of jurisdiction, here July 14, 2005. Id. at 1192 n.4. As the 

district court correctly observed, Dozier explicitly holds that “a plaintiff cannot relitigate a 

jurisdictional dismissal by relying upon those facts that existed at the time of the first 

dismissal.” Citizen II, slip op. at 6 (citing Dozier, 702 F.2d at 1192 n.4). Here, the 

German suit of March 14, 2005 and OSRAM’s statements of May 2, 2005 existed at the 

time of dismissal of CE’s first DJ action. Therefore, CE is estopped from relying on 

these events as supporting an “actual controversy” in its August 2, 2005, second DJ 

2006-1211 5
complaint. 

CE points to GAF Corp., 818 F.2d at 912-13, as evidence that later D.C. Circuit 

decisions undermine the holding of Dozier. However, the D.C. Circuit explicitly stated in 

GAF Corp., “A claim of jurisdiction is not precluded if, however, in the interim 

subsequent to the initial dismissal there are developments tending to ‘cure’ the 

jurisdictional deficiency identified in the first suit.” GAF Corp., 818 F.2d at 912-13 

(emphasis added). Thus, CE’s argument must fail. 

Finally, CE argues that D.C. Circuit law conflicts with Federal Circuit standards 

for DJ actions purportedly espoused in Arrowhead Industrial Water, Inc. v. Ecolochem, 

Inc., 846 F.2d 731, 734 (Fed. Cir. 1988) and GAF Building Materials Corp. v. Elk Corp. 

of Dallas, 90 F.3d 479, 483 (Fed. Cir. 1996). Specifically, CE asserts that our decisions 

in these cases would have precluded CE from filing an amended complaint prior to the 

district court’s first dismissal on July 14, 2005. We decline to read these cases as 

creating a conflict with D.C. Circuit law or even relevant here, as neither GAF Building 

Materials nor Arrowhead are directed to issue preclusion or res judicata in general. 

Assuming they were relevant, to the extent that a conflict may exist our precedent 

clearly requires us to follow D.C. Circuit law, not Federal Circuit law. 

Since CE was estopped from relying on the events of March 14, 2005 and May 2, 

2005, the district court did not err in holding that service of process did not cure its lack 

of subject matter jurisdiction over CE’s DJ action.
