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

PER CURIAM. 

DECISION 

Allegra D. Hemphill appeals from an order issued by the United States District 

Court for the District of Columbia enjoining her from filing any new patent infringement 

lawsuits against Proctor & Gamble Company (“P&G”) and Kimberly-Clark Corporation 
(“K-C”) without prior leave of court. In view of Ms. Hemphill’s history of bringing 

meritless and duplicative litigation against P&G and K-C, we hold that the trial court did 

not abuse its discretion by entering the order. We therefore affirm. 

BACKGROUND 

Ms. Hemphill is the named inventor on United States Patent No. 4,557,720 (“the 

’720 patent”), which claims a “vaginal swab” having a core member, an adsorbent layer, 

and an outer housing with an annular band. Ms. Hemphill has prosecuted a number of 

actions and appeals based on the ’720 patent, none of which has been successful. 

Ms. Hemphill first suit in March 1999 against Johnson & Johnson/McNeil-PPC, 

Inc., in the United States District Court for the District of Maryland (“Hemphill I”). In that 

action, she alleged that certain sanitary napkin products infringed claim 2 of the ’720 

patent. The Maryland court noted that, during prosecution, Ms. Hemphill had 

distinguished her invention over the prior art by stating that her vaginal swab had “an 

elongated structure . . . to be introduced into the vaginal cavity” and “d[id] not behave, 

operate, or function like a sanitary napkin.” Hemphill v. McNeil-PPC, Inc., 134 F. Supp. 

2d 719, 723, 726 (D. Md. 2001). The Maryland court thus construed the claim term 

“vaginal swab” to mean a device having “a size and structure for cleansing or applying 

medicine within the vaginal canal.” Id. at 726. Based on its claim construction and Ms. 

Hemphill’s disclaimers, the Maryland court held that the defendants were entitled to 

summary judgment of non-infringement. Id. at 729. Ms. Hemphill appealed, and this 

court affirmed. Ms. Hemphill then sought certiorari from the United States Supreme 

Court, which was denied. 

2010-1047 2 
Ms. Hemphill next filed an action against P&G and K-C in the Maryland district 

court in November 2002 (“Hemphill II”). In Hemphill II, Ms. Hemphill alleged that P&G’s 

ALWAYS® products and K-C’s KOTEX® and POISE® products infringed claim 1 of the 

’720 patent. Applying the same claim construction that it had applied in Hemphill I, the 

Maryland court again concluded that the defendants’ accused sanitary napkin products 

did not constitute “vaginal swabs” as that term was used in the patent. Hemphill v. 

Procter & Gamble Co., 258 F. Supp. 2d 410, 416-18 (D. Md. 2003). The Maryland court 

granted summary judgment of non-infringement on that ground. 

Ms. Hemphill appealed the decision in Hemphill II, and this court affirmed the 

Maryland court’s judgment, upholding that court’s application of the prior claim 

construction to the same claim terms. Ms. Hemphill’s request for review by the 

Supreme Court was denied. Despite the resolution of that case against her, Ms. 

Hemphill filed a motion in the Maryland district court in June 2005 seeking entry of a 

“Final Judgment” in her favor. That motion was denied, and Ms. Hemphill 

unsuccessfully appealed to this court and sought certiorari from the Supreme Court. 

In July 2007, Ms. Hemphill filed another action, this time in the United States 

District Court for the District of Columbia, accusing the ALWAYS®, KOTEX®, and 

POISE® products of infringing claim 2 of the ’720 patent (“Hemphill III”). The D.C. 

district court granted the defendants’ motion to dismiss the complaint on the ground of 

res judicata. Ms. Hemphill moved for reconsideration under Federal Rule of Civil 

Procedure 60(b), arguing that P&G and K-C had engaged in fraud during the course of 

the litigation. The D.C. district court rejected Ms. Hemphill’s claims as “baseless 

accusations” and denied relief. Ms. Hemphill then filed an appeal with the United States 

2010-1047 3 
Court of Appeals for the D.C. Circuit, which transferred the case to this court. We 

summarily affirmed the district court’s decision and denied Ms. Hemphill’s subsequent 

request for reconsideration. 

On January 2, 2009, Ms. Hemphill filed the present lawsuit against P&G and K-C 

in the D.C. district court, alleging “fraud upon the court” and “conspiracy” (“Hemphill IV”). 

Specifically, Ms. Hemphill alleged that P&G, K-C, and their attorneys had deceived the 

courts in prior cases by “claiming that the products Ms. Hemphill accuses of infringing 

her ’720 patent were ‘sanitary napkins’ . . . [when] they knew or should have known that 

the personal hygiene products with brand names Always®, Kotex® and Poise® . . . are 

labeled as ‘pads’, ‘maxi-pads’, ‘mini-pads’ etc.” She further alleged that the defendants 

had submitted false declarations and exhibits that deceived the courts regarding which 

products were accused of infringement. On March 31, 2009, the D.C. court dismissed 

the complaint based on res judicata, concluding that Ms. Hemphill “could have raised—

and indeed did raise—the same accusations in Hemphill III” in her Rule 60(b) motion. 

Notwithstanding the district court’s warning that “[i]t is time for Ms. Hemphill to 

accept the judgments of the courts and to cease suing Defendants,” Ms. Hemphill 

subsequently moved for reconsideration, or in the alternative to alter or amend the 

judgment under Federal Rule of Civil Procedure 59(e). She again argued that the 

defendants had deceived the court and had “tampered with the evidence” pertaining to 

the accused products. The defendants requested that the district court impose 

sanctions against Ms. Hemphill, including a pre-filing injunction that would limit her right 

to file new patent infringement actions against them. The district court denied Ms. 

2010-1047 4 
Hemphill’s Rule 59(e) motion on April 29, 2009, and ordered Ms. Hemphill to show 

cause why she should not be sanctioned for her conduct in the litigation. 

After Ms. Hemphill again attempted to reassert her fraud arguments, the district 

court granted in part P&G and K-C’s motion for sanctions under Federal Rule of Civil 

Procedure 11. The sanctions order, issued on June 1, 2009, enjoined Ms. Hemphill 

from filing any new patent infringement lawsuits against P&G or K-C without first 

obtaining leave of the D.C. district court. The court further required Ms. Hemphill to 

certify and explain how any new complaint raises matters not previously decided by any 

federal court. On June 29, 2009, Ms. Hemphill appealed the sanctions order to the D.C. 

Circuit, which transferred the appeal to this court. 

DISCUSSION 

 Although Ms. Hemphill attempts to reassert her fraud claims and by extension 

her earlier patent infringement claims, the only matter properly before this court is the 

district court’s sanctions order, because Ms. Hemphill failed to take a timely appeal from 

the district court’s dismissal of her complaint and the denial of her Rule 59(e) motion. 

Under 28 U.S.C. § 2107(a) and Federal Rule of Appellate Procedure 4(a), Ms. Hemphill 

had 30 days from the date of the order denying her Rule 59(e) motion (i.e., until May 29, 

2009) to file an appeal on the merits of the dismissal order. However, she filed her 

notice of appeal on June 29, 2009, and she referenced only the district court’s sanctions 

order in that notice. Because we lack jurisdiction to address Ms. Hemphill’s arguments 

pertaining to the allegations of fraud and conspiracy, we confine our discussion to the 

sanctions order. 

2010-1047 5 
 When reviewing the imposition of sanctions under Rule 11, this court applies the 

law of the regional circuit in which the district court sits. Q-Pharma, Inc. v. Andrew 

Jergens Co., 360 F.3d 1295, 1299 (Fed. Cir. 2004). Under D.C. Circuit law, the 

appellate court reviews a Rule 11 determination for an abuse of discretion. See Lucas 

v. Duncan, 574 F.3d 772, 775 (D.C. Cir. 2009). A court’s decision to impose an antifiling injunction is also reviewed for abuse of discretion. See SEC v. Banner Fund Int’l, 

211 F.3d 602, 616 (D.C. Cir. 2000). 

 The D.C. Circuit’s decision in In re Powell, 851 F.2d 427 (D.C. Cir. 1988), sets 

forth guidelines for anti-filing injunctions involving pro se litigants. The Powell court 

emphasized that an injunction is “an extreme remedy” and that, in fashioning 

appropriate injunctive relief, the court must “take great care not to unduly impair a 

litigant’s constitutional right of access to the courts.” Id. at 430-31. In particular, “the 

district court should endeavor to create an adequate record for review.” Id. at 431. 

Moreover, a pro se litigant should be afforded an opportunity to oppose the entry of an 

anti-filing order before it is entered. Id. Finally, “it is incumbent upon the district court to 

make substantive findings as to the frivolous or harassing nature of the litigant’s 

actions.” Id. In so doing, the court should make findings “as to any pattern” of behavior, 

looking to “both the number and content of the filings as indicia of frivolousness and 

harassment.” Id. We conclude that the D.C. district court did not abuse its discretion in 

imposing the sanction of an anti-filing injunction in this case. 

First, the district court created a full record to support the injunction, reviewing 

hundreds of pages of largely repetitive filings by Ms. Hemphill and providing clear 

explanations for its rejection of each of Ms. Hemphill’s claims. The district court’s order 

2010-1047 6 
dismissing Ms. Hemphill’s complaint chronicles the decade-long history of Ms. 

Hemphill’s litigation of the ’720 patent. The record also shows that the court 

considered, but declined to grant, an earlier motion to impose sanctions on Ms. 

Hemphill. 

 Second, the court gave Ms. Hemphill an opportunity to oppose the entry of 

sanctions against her. To be sure, rather than informing Ms. Hemphill that she might be 

restricted from filing future lawsuits, as suggested by Powell, the district court ordered 

Ms. Hemphill to show cause “why the Court should not sanction her by assessing a fine 

for bringing this duplicative lawsuit.” Under the circumstances, however, we conclude 

that the order’s reference to monetary sanctions, rather than restrictions on filing, did 

not render it insufficient to support the final sanctions order. Significantly, Ms. Hemphill 

was placed on notice that she could be subjected to an anti-filing injunction, because 

P&G and K-C filed motions both in this case and in the earlier D.C. district court case 

requesting that the court impose such an order. In addition, in its pre-motion letter of 

February 25, 2009, P&G warned Ms. Hemphill of its intention to seek an anti-filing 

injunction. It is thus clear that Ms. Hemphill was put on notice of the possibility of an 

anti-filing injunction. Moreover, it seems highly unlikely that she would have responded 

any differently if the court had expressly referred to the requested anti-filing injunction in 

its order to show cause. In her response to the order to show cause, Ms. Hemphill did 

not address the specific proposed sanctions, but instead simply reasserted her fraud 

arguments, stating that “[t]he Court should not expect Ms. Hemphill to accept or be 

satisfied with the false product the defendants’ [sic] provided in the original lawsuit.” 

The district court cited that statement in its final sanctions order as a basis for its 

2010-1047 7 
conclusion that Ms. Hemphill would “continue pursuing her meritless infringement 

claims” unless the court took appropriate measures to prevent her from doing so. Thus, 

the district court’s failure to include a specific reference to the possible imposition of an 

anti-filing injunction in its order to show cause, while perhaps error under Powell, was 

harmless. 

 Third, the district court made ample findings regarding the harassing and 

frivolous nature of Ms. Hemphill’s actions, discussing both the number of her filings and 

their lack of merit. In its sanctions order, the court observed that, despite numerous 

warnings, Ms. Hemphill persisted in “embroil[ing] Defendants in never-ending baseless 

litigation.” The court also reiterated its concern that “absent sanctions, Ms. Hemphill will 

continue to harass Defendants indefinitely irrespective of the judgments of the courts.” 

Characterizing Ms. Hemphill’s claims as meritless attempts to “circumvent the courts’ 

judgments,” the court noted the repeated rejection of Ms. Hemphill’s patent infringement 

claims, as well as its own rejection, for the fourth time, of Ms. Hemphill’s asserted 

distinction between “sanitary napkins” and “pads.” 

The court’s findings are well supported by the record. Ms. Hemphill has engaged 

in a vexatious pattern of filing multiple duplicative lawsuits, forum-shopping among 

various district and appellate courts, and requesting reconsideration of every adverse 

ruling in every case. It is also apparent that her claims are without merit. Her 

infringement claims are baseless in light of the conclusions in Hemphill I (affirmed by 

this court) that Ms. Hemphill disclaimed coverage of sanitary napkin products during the 

prosecution of the ’720 patent and that key terms common to both claims of the ’720 

patent must be construed to exclude sanitary napkin products. 

2010-1047 8 
2010-1047 9 

There likewise appears to be no support for Ms. Hemphill’s assertions of fraud. 

Ms. Hemphill continues to provide no basis for her distinction between “sanitary 

napkins” and “pads,” nor does she present any evidence that her opponents’ use of 

such terminology was deceptive or misleading to the courts. Ms. Hemphill also provides 

no support for her suggestion that the defendants’ allegedly fraudulent exhibits, which 

depicted the ALWAYS®, KOTEX®, and POISE® products without their disposable outer 

wrappers, deceived the courts into believing that those accused products lacked such 

wrappers. In fact, the court in Hemphill II explicitly recognized that the accused 

products included disposable plastic wrappers but concluded that those wrappers did 

not satisfy the “outer housing” claim limitation in the ’720 patent. See Hemphill, 258 F. 

Supp. 2d at 417. 

Finally, the district court’s injunction does not impose an excessive burden on 

Ms. Hemphill’s filing rights. It is narrowly tailored to restrict only new patent 

infringement suits against P&G and K-C, and it allows Ms. Hemphill to litigate if she 

obtains permission from the court and certifies that the suit raises new, previously 

undecided issues. Moreover, the language of the injunction comports with that of other 

anti-filing injunctions upheld by the D.C. Circuit. See, e.g., Urban v. United Nations, 768 

F.2d 1497 (D.C. Cir. 1985). We therefore conclude that the district court did not abuse 

its discretion when it entered an anti-filing injunction against Ms. Hemphill.
