MEMORANDUM IN SUPPORT OF PFIZER INC.’S MOTION FOR LEAVE TO INTERVENE 1 Pfizer Inc. (“Pfizer”), by and through undersigned counsel, hereby submits this 
Memorandum of Points and Authorities in Support of Pfizer’s Motion for Leave to Intervene for 
a Limited Purpose, pursuant to Rules 24(a) and 24(b) of the Federal Rules of Civil Procedure.  
Pfizer seeks to intervene in this action brought by Public Health and Medical Professionals for 
Transparency (“Plaintiff” or “PHMPT”) under the Freedom of Information Act, 5 U.S.C. § 552, 
as amended (“FOIA”) for the limited purpose of protecting statutorily-protected confidential 
information relating to its COVID-19 vaccine.   
PRELIMINARY STATEMENT 
In this action, Plaintiff seeks to compel the Food and Drug Administration (“FDA” or 
“Agency”) to respond to its FOIA request on an expedited basis and to produce a significant 
volume of data and information submitted by Pfizer to FDA as part of its application for regulatory 
approval of the Pfizer-BioNTech COVID-19 vaccine (“the vaccine” or “Comirnaty”).  The vaccine 
received FDA approval, through a BLA, for use in individuals 16 years and older on August 23, 
2021.  See News Release, U.S. Food & Drug Admin., FDA Approves First COVID-19 Vaccine 
(Aug. 23, 2021), https://www.fda.gov/news-events/press-announcements/fda-approves-first-
covid-19-vaccine . 
Pfizer supports the public disclosure of the vast majority of this information to promote 
transparency and the public’s confidence in the vaccine, and Pfizer seeks to intervene for the 
limited purpose of ensuring that information that is exempt from disclosure under FOIA is not 
disclosed inappropriately.  Indeed Pfizer, FDA, the Centers for Disease Control and Prevention 
(“CDC”), and other government agencies already have made public extensive data about the 
vaccine.  By way of example, Pfizer has shared the following information over the course of 
developing the vaccine: Case 4:21-cv-01058-P   Document 41   Filed 01/21/22    Page 6 of 16   PageID 1770Case 4:21-cv-01058-P   Document 41   Filed 01/21/22    Page 6 of 16   PageID 1770

FACTUAL BACKGROUND 
Plaintiff submitted its FOIA request for this information to FDA on August 27, 2021.  
Compl., Ex. A.1, ECF No. 1-1 (the “FOIA Request”).  In the FOIA request, Plaintiff seeks, 
pursuant to 21 C.F.R. § 601.51(e), data and information contained in the biologics license 
application (“BLA”) for the vaccine, including inter alia, test protocols, safety and effectiveness 
data, correspondence and written summaries of discussions relating to the biological product file, 
adverse event reports, lot testing records, and other data, “with the exception of publicly available 
reports on the Vaccine Adverse Events Reporting System.”  See FOIA Request 2.  While Pfizer 
supports the public review of much of this information which will help build trust and confidence 
in the vaccine, the records Plaintiff has requested also contain information exempt from production 
under FOIA, including the personal privacy information of individuals who participated in clinical 
trials and confidential business and trade secret information of Pfizer, such as its proprietary 
manufacturing processes.  See 5 U.S.C. § 552(b)(4), (b)(6).  Case 4:21-cv-01058-P   Document 41   Filed 01/21/22    Page 8 of 16   PageID 1772Case 4:21-cv-01058-P   Document 41   Filed 01/21/22    Page 8 of 16   PageID 1772
 
MEMORANDUM IN SUPPORT OF PFIZER INC.’S MOTION FOR LEAVE TO INTERVENE 4 After FDA denied Plaintiff’s request for expedited processing of the FOIA request, 
Plaintiff commenced this action on September 16, 2021.  See Compl. ¶¶ 41–53. 
This Court held a Scheduling Conference in this matter on December 14, 2021.  In briefing 
submitted to this Court in advance of that Conference, counsel for FDA emphasized that the 
Agency supports Plaintiff’s general right to the information sought in its FOIA request, subject to 
standard exemptions under FOIA for sensitive business and confidential personal information.  
See, e.g., First Joint Report 6 (Nov. 5, 2021), ECF No. 18 (“FDA is committed to transparency, in 
general, and in particular with respect to records related to the Biological License Application 
(‘BLA’) for the Comirnaty vaccine”).  FDA expressed concern, however, about its ability to 
adequately review the volume of requested information in the timeframe that Plaintiff proposed in 
order to protect against the inadvertent disclosure of trade secrets, sensitive commercial and 
financial information, and confidential personal information about clinical trial test subjects.  See, 
e.g., First Joint Report 7 (“To ensure protection of this information, and other information subject 
to withholding under the FOIA exemptions, FDA must carefully review and, if necessary, redact 
exempt information on a line-by-line basis. . . . [I]t is not feasible for FDA to review and produce 
the substantial volume of records that Plaintiff seeks to obtain on a short timeframe.”); Second 
Joint Report 5 (Nov. 15, 2021), ECF No. 20 (“This type of review for more than 329,000 pages 
will necessarily require time if the agency is going to be able to perform the careful analysis 
necessary to protect sensitive information.”).  At the Scheduling Conference, the Court suggested 
that intervention by Pfizer would be advisable given these concerns.  Pfizer was not aware of 
Plaintiff’s FOIA request or this litigation prior to reading news reports about this Scheduling 
Conference in December 2021.   Case 4:21-cv-01058-P   Document 41   Filed 01/21/22    Page 9 of 16   PageID 1773Case 4:21-cv-01058-P   Document 41   Filed 01/21/22    Page 9 of 16   PageID 1773
 
MEMORANDUM IN SUPPORT OF PFIZER INC.’S MOTION FOR LEAVE TO INTERVENE 5 On January 6, 2022, the Court issued an Order requiring disclosure of more than 12,000 
pages of information responsive to Plaintiff’s FOIA request by January 31, 2022, and subsequently 
at a rate of 55,000 pages every 30 days, including production of redacted versions of any 
documents for which FDA claims a privilege, exemption, or exclusion.  See Order, ECF No. 35.   
In light of FDA’s statements regarding its capacity to review the requested information at 
an increased pace, and this Court’s order to produce this information on an expedited basis, Pfizer 
seeks leave to intervene in this action for the limited purpose of ensuring that information exempt 
from disclosure under FOIA is adequately protected as FDA complies with this Court’s order.   
ARGUMENT 
I. PFIZER IS ENTITLED TO INTERVENE AS A MATTER OF RIGHT UNDER 
RULE 24(A) 
Rule 24(a) of the Federal Rules of Civil Procedure sets forth the requirements for 
intervention as a matter of right.  See Fed. R. Civ. P. 24(a)(2); Entergy Gulf States Louisiana, 
L.L.C. v. U.S. EPA , 817 F.3d 198, 203 (5th Cir. 2016).  To intervene pursuant to Rule 24(a), an 
applicant must satisfy four requirements: 
(1) the application for intervention must be timely; (2) the applicant 
must have an interest relating to the property or transaction which is 
the subject of the action; (3) the applicant must be so situated that 
the disposition of the action may, as a practical matter, impair or 
impede his ability to protect that interest; (4) the applicant’s interest 
must be inadequately represented by the existing parties to the suit.

of the Orleans Levee Dist. , 493 F.3d 570, 578 (5th Cir. 2007)); see also In re Lease Oil Antitrust

MEMORANDUM IN SUPPORT OF PFIZER INC.’S MOTION FOR LEAVE TO INTERVENE 6 (quoting Brumfield v. Dodd , 749 F.3d 339, 341 (5th Cir. 2014)); Wal–Mart Stores, Inc. v. Texas 
Alcoholic Beverage Comm’n , 834 F.3d 562, 565 (5th Cir. 2016) (same).  Intervention should be 
allowed “where no one would be hurt and the greater justice could be attained.”  John Doe No. 1 
v. Glickman , 256 F.3d 371, 375 (5th Cir. 2001); see also Wal–Mart Stores, Inc. , 834 F.3d at 565 
(same).  As set forth below, the requirements for intervention as of right are satisfied here.   
A. Pfizer’s Motion to Intervene is Timely 
First, Pfizer’s motion to intervene is timely.  Pfizer first learned of this litigation just one 
month ago.  Rule 24 does not provide a specific deadline by which parties should move to 
intervene, but courts routinely treat motions filed within several months after an intervenor learns 
of its stake in an action as timely.  See, e.g., John Doe No. 1 , 256 F.3d at 377–78 (finding 
intervenor’s motion to intervene timely when filed a month after it became aware of its stake in 
the lawsuit);  Wal–Mart Stores, Inc. , 834 F.3d at 565–66 (holding motion to intervene was timely 
when filed three months after defendant filed its answer following denial of motion to dismiss).   
Moreover, the Fifth Circuit consistently emphasizes that courts “should discourage 
premature intervention because it wastes judicial resources.”  John Doe No. 1 , 256 F.3d at 376 
(quoting Sierra Club v. Espy , 18 F.3d 1202, 1206 (5th Cir. 1994) (internal quotation marks and 
alterations omitted)).  “Thus, the timeliness clock runs either from the time the applicant knew or 
reasonably should have known of his stake in the case into which he seeks to intervene or from the 
time he became aware that his stake would no longer be protected by the existing parties to the 
lawsuit.”  Id.  (internal quotation marks and citations omitted).  Here, Pfizer learned of this action 
from news reports in connection with the December 14, 2021 Scheduling Conference, and 
reviewed FDA’s statements raising concerns about its ability to review the BLA adequately for 
FOIA-exempt material under the Court’s timeline shortly thereafter.  In light of the above, Pfizer 
filed its limited motion to intervene on January 21, 2022.  Accordingly, Pfizer’s motion is timely.   Case 4:21-cv-01058-P   Document 41   Filed 01/21/22    Page 11 of 16   PageID 1775Case 4:21-cv-01058-P   Document 41   Filed 01/21/22    Page 11 of 16   PageID 1775
 
MEMORANDUM IN SUPPORT OF PFIZER INC.’S MOTION FOR LEAVE TO INTERVENE 7 B. Pfizer Has a Direct Interest Relating to the Action  
Pfizer satisfies Rule 24(a)’s second element, which requires that it have a “direct, 
substantial, [and] legally protectable” interest in the property or transaction that forms the basis of 
the controversy.”  Espy, 18 F.3d at 1207.  Pfizer’s interest in protecting its proprietary trade secret 
and confidential commercial information meets this standard.  A “property interest . . . is the most 
elementary type of right that Rule 24(a) is designed to protect.”  Texas v. United States,  805 F.3d 
653, 658 (5th Cir. 2015) (internal quotation marks and citation omitted).  Courts routinely grant 
motions to intervene in FOIA cases involving FDA where a manufacturer seeks to protect its 
confidential business information.  See, e.g., Pub. Citizen Health Rsch. Grp. v. FDA , 185 F.3d 898, 
900 (D.C. Cir. 1999) (noting that a drug manufacturer intervened to protect confidential 
information from disclosure under FOIA); Appleton v.  FDA, 310 F. Supp. 2d 194, 196–97 (D.D.C. 
2004) (permitting New Drug Application (“NDA”) holders to intervene as a matter of right in 
FOIA lawsuit seeking release of materials from  the FDA’s review of NDAs). 
C. Disposition of this Action May Impair Pfizer’s Ability to Protect Its Interests  
Based on FDA’s recent statements about its ability to review the BLA adequately for 
Pfizer’s confidential information under the required timeline, there is a risk that this matter could 
result in inadvertent disclosure of FOIA-protected material.  Pfizer’s ability to protect its interests 
would be directly impaired if its trade secrets and other proprietary information were disclosed as 
a result of this action.  See, e.g., Appleton , 310 F. Supp. 2d at 197 (“[D]isclosure[] resulting from 
the disposition of this action could impair the applicants’ ability to protect their trade secrets or 
confidential information.”).  While much of the information sought by Plaintiff relates to the safety 
and efficacy of the vaccine, and Pfizer supports the disclosure of that information to promote 
confidence in the vaccine, certain other information in the BLA reflects Pfizer’s trade secrets and Case 4:21-cv-01058-P   Document 41   Filed 01/21/22    Page 12 of 16   PageID 1776Case 4:21-cv-01058-P   Document 41   Filed 01/21/22    Page 12 of 16   PageID 1776
 
MEMORANDUM IN SUPPORT OF PFIZER INC.’S MOTION FOR LEAVE TO INTERVENE 8 confidential commercial information, the disclosure of which would cause substantial harm to 
Pfizer’s business interests.  As such, Pfizer satisfies Rule 24(a)’s third element.   
D. Pfizer’s Interests Are Not Adequately Represented by Existing Parties  
The final requirement for intervention under Rule 24(a) is that the “applicant’s interest 
must be inadequately represented by the existing parties to the suit.”  Entergy, 817 F.3d at 203.  
“The applicant has the burden of demonstrating inadequate representation, but this burden is 
‘minimal.’”  Id. (quoting Brumfield , 749 F.3d at 345); see also Trbovich v. United Mine Workers , 
404 U.S. 528, 538 n.10 (1972) (same).  Courts in the Fifth Circuit have held that the mere 
possibility that representation may be inadequate satisfies this requirement for intervention.  
Entergy, 817 F.3d at 203 (The applicant need only “show[] that representation . . . ‘may be’ 
inadequate.”) (quoting Haspel, 493 F.3d at 578); see also Espy , 18 F.3d at 1207 (same); see also 
Trbovich, 404 U.S. at 538 n.10 (same).  
FDA’s general interest in avoiding the disclosure of proprietary and private information 
does not ensure that FDA will adequately protect Pfizer’s business interests.  Indeed, it is well-
established in this Circuit that Government entities generally cannot adequately represent the 
interests of aspiring intervenors, especially where the government “must represent the broad public 
interest,” while the intervenor seeks to protect specific concerns, such as an individual company’s 
proprietary or economic rights.  Espy, 18 F.3d at 1208 (“Given the minimal burden on the movants 
to satisfy this requirement, we conclude that the government’s representation of the intervenors’ 
interest is inadequate.”); see also John Doe No. 1 , 256 F.3d at 381 (same).  Likewise, although 
Pfizer and Plaintiff share an interest in transparency regarding the vaccine, that commonality does 
not extend to Pfizer’s trade secrets or confidential commercial information.  Moreover, Pfizer is 
uniquely positioned to evaluate the potential commercial sensitivities associated with the 
production of its regulatory submissions and identify trade secrets and other protected confidential Case 4:21-cv-01058-P   Document 41   Filed 01/21/22    Page 13 of 16   PageID 1777Case 4:21-cv-01058-P   Document 41   Filed 01/21/22    Page 13 of 16   PageID 1777
 
MEMORANDUM IN SUPPORT OF PFIZER INC.’S MOTION FOR LEAVE TO INTERVENE 9 information.  Thus, while Pfizer shares some interests with the existing Parties, Pfizer ultimately 
must intervene to protect its unique business interests and is best positioned to do so.   
E. Pfizer Has Standing in This Action 
The Supreme Court has held that “an intervenor of right must have Article III standing in 
order to pursue relief that is different from that which is sought by a party with standing.” See 
DeOtte v. Azar , 332 F.R.D. 173, 179 (N.D. Tex. 2019) (citing Town of Chester, N.Y. v. Laroe Ests., 
Inc., 137 S. Ct. 1645, 1648 (2017)).  This Court has found, however, that this standing requirement 
is limited to instances where a plaintiff-intervenor is affirmatively seeking relief.  See Franciscan 
All., Inc. v. Azar , 414 F. Supp. 3d 928, 938 n.3 (N.D. Tex. 2019) (concluding when defendant-
intervenors did not “seek relief” and “as long as they do not also intend to add an affirmative claim 
for relief during the district court proceedings, Putative Intervenors need not establish standing to 
intervene.”).  Because Pfizer is not seeking affirmative relief and is intervening for the limited 
purpose of protecting its business interest by ensuring compliance with FOIA’s statutory 
exemptions, the standing requirement should not apply here. 
Nonetheless, to the extent the standing requirement applies, Pfizer has standing to 
intervene.  To establish standing under Article III, a prospective intervenor must show: (1) injury-
in-fact, (2) causation, and (3) redressability.  DeOtte, 332 F.R.D. at 179 (citing Lujan v. Defs. of 
Wildlife, 504 U.S. 555, 560 (1992)).  Here, Pfizer’s injury-in-fact is the potential disclosure of its 
trade secrets and confidential commercial information and the associated economic harm to Pfizer.  
As to causation, the relief requested by Plaintiff could deprive Pfizer of its intellectual property 
rights if Pfizer is not afforded the opportunity to advocate for protection of certain confidential 
commercial information within the larger set of information to be disclosed.  Redressability, 
likewise, is satisfied, as the risk of injury to Pfizer likely will be minimized by its intervention and Case 4:21-cv-01058-P   Document 41   Filed 01/21/22    Page 14 of 16   PageID 1778Case 4:21-cv-01058-P   Document 41   Filed 01/21/22    Page 14 of 16   PageID 1778
 
MEMORANDUM IN SUPPORT OF PFIZER INC.’S MOTION FOR LEAVE TO INTERVENE 10 the implementation of a production protocol that safeguards against the disclosure of trade secrets 
and other confidential commercial information.   
Because it satisfies the requirements for intervention under Rule 24(a), Pfizer respectfully 
asks that this Court permit it to intervene in this action as a matter of right.   
II. IN THE ALTERNATIVE, THIS COURT SHOULD PERMIT PFIZER TO 
INTERVENE UNDER RULE 24(B) 
Alternatively, if the Court finds that Pfizer does not have the right to intervene under Rule 
24(a), Pfizer respectfully requests that this Court grant it permission to intervene under Rule 24(b).  
Courts have discretion to permit intervention where the movant “has a claim or defense that shares 
with the main action a common question of law or fact.” Fed. R. Civ. P. 24(b)(1)(B).  In 
considering a motion for permissive intervention, the Court considers whether the motion is timely 
and whether the proposed intervention will “unduly delay or prejudice the adjudication of the 
rights of the original parties.” Fed. R. Civ. P. 24(b)(3); see also United States v. Colvin , 203 B.R. 
930, 941 (N.D. Tex. 1996). 
 Pfizer’s interest in protecting its trade secrets and confidential commercial information 
shares questions of both law and fact in common with the present case.  As shown above, Pfizer’s 
motion also is timely.  Moreover, Pfizer’s intervention will not prejudice the Parties because Pfizer 
does not dispute that Plaintiff is entitled to non-exempt information from the BLA under its FOIA 
request and Pfizer does not seek any delay in the production of that information.  Rather, Pfizer’s 
intervention will facilitate production of the information Plaintiff seeks since Pfizer can assist the 
Parties in efficiently segregating and redacting any data and information that are subject to FOIA 
statutory exemptions.   Case 4:21-cv-01058-P   Document 41   Filed 01/21/22    Page 15 of 16   PageID 1779Case 4:21-cv-01058-P   Document 41   Filed 01/21/22    Page 15 of 16   PageID 1779
