Food and drug production has been regulated by the United States since 1906. The Food and Drug Administration (“FDA”) is one of the oldest consumer protection agencies in this country. The FDA protects the public from unsafe foods and drugs to medical devices and cosmetics. It also protects the rights and safety of patients in clinical trials of new medical products.
The Drug Price Competition and Patent Term Restoration Act of 1984, commonly known as the Hatch-Waxman Act (“Act”), was passed to expedite the FDA’s approval of generic drugs. Studies show that since its inception, the Act increased the number of generic drugs by 50%, with almost every leading drug, off-patent, competing with at least two generic brands. The generic drug industry has become a multi-billion dollar industry.
The Act attempts to increase competition and drive down drug prices while simultaneously maintaining the brand name drug companies’ incentive to invest in new research. It is arguable that the Act has achieved its purpose. Brand name drug companies (“Branders”), however, are fighting to retain their monopoly on patents. These Branders have found loopholes in the Act by which they extend their patents and tie up generic approval. To put the story in context, one week of patent extension translates into hundreds of millions of dollars for Branders. In response, legislators are fighting to close these loopholes and to lower healthcare costs. This paper is a research guide for individuals interested in the generic pharmaceutical industry, whether it is a consumer, chemist, consultant or attorney. The rise in healthcare costs and the inclusion of prescription drug coverage by the Medicare Program are just two of the catalysts for this growing field. This paper guides individuals to current laws, regulations, cases and news-worthy articles concerning the industry. Furthermore, the paper explores public policy arguments and political rhetoric surrounding generic pharmaceuticals.
a. TerminologY: The amount of time you spend searching a subject is decreased when the correct spelling and terminology are employed. When I first started searching the internet and library cataloging systems, I grew frustrated because the search yielded an unfocused result. I have included the following search terms to help you with your search and allow you to supplement this pathfinder with updated searches. Here are the Trigger Words: (1) generic drug, (2) pharmaceutical drug, (3) Hatch-Waxman Act, (4) pharmaceutical patent, (5) abbreviated new drug application, (6) generic pharmaceutical, and (7) pharmaceutical patent extension.
By today’s standards a thorough search begins with Google. It’s true, Google’s search engine yields a plethora of websites, information and advertisements. Many of the hits, however, will be worthless to your research. Nevertheless, begin your search with Google and if you see any interesting sites, click on the link.
A word of advice: if a website ends in “.gov,” it is government sponsored, “.org,” organizationally sponsored, “.edu,” school sponsored, and “.com” is a catch-all. Be careful to evaluate the websites to make sure you are not receiving any false or misleading information.
I would suggest you arm yourself with a background and history of the industry before you dive into particularized research. A wealth of knowledge as to patents, generic drugs and the regulation of the industry can be found on www.fda.gov. FDA.gov contains links to the Orange Book, Center for Drug Evaluation and Research (“CDER”), and the majority of information that anyone would need. The website also provides a Drug Information Pathfinder.
To search for books, use the #trigger”>Trigger Words and search Amazon.com. It is nice to search Amazon before going to your local library because a search yields the most popular and current books in the market. Additionally, you can browse the books online before searching for the hard copy. The search on Amazon will also yield journal articles and periodicals that you can order for a low price without having to subscribe to the journal.

Since the enactment of the Act, Branders have attempted to block the approval of generic patents in three primary ways: (1) the 180 Day Exclusivity Provision, (2) the 30 Month Automatic Stay, and (3) the Citizens’ Petition. Following is an analysis of the courts’ holdings and rationales. Note that in 2003 the 108th Congress enacted legislation, Title XI of H.R. 1, which amended the Act. The discussion below incorporates these Amendments.
2. Matthew Bender – http://bender.lexisnexis.com or Matthew Bender, Intellectual Property Counseling and Litigation, Part III “Litigating the Intellectual Property Case.” If you want to understand the litigation process of pharmaceutical patents, Matthew Bender Authority is a great place to start. It provides you with boilerplate language, checklists, and strategies. The resource is an invaluable outline of litigation procedures ranging from pre-filing discovery to damages. The resource also contains an appendix for local patent rules of practice. Other volumes that may be of help in preparing for litigation are: (1) American Jurisprudence Trial and (2) Proof of Fact. All three of these secondary sources can be found at your nearest law library.
3. 180 Day Exclusivity Provision
The first generic applicant to file a paragraph IV certification is awarded a 180-day exclusivity period by the FDA. Prior to the 2003 Amendments, this provision was abused by generic companies and Branders. For example, Branders would offer to pay the generic company a premium over what they would make in the market. In return, the generic company would not market the product and the exclusivity period would not initiate. Thus, other generic companies were blocked from entering the market because the exclusivity period never ran.
The 2003 Amendments, however, require abandonment of the 180 day exclusivity if marketing is not initiated within a regulated time frame. For more detailed information on how the FDA deals with the exclusivity period visit FDA.gov. Case Law includes Abbott Lab. v. Geneva Pharm., Andrx Pharm., Inc. v. Biovail Corp. Intern, and McGrew v. Schering-Plough Corp., all of which are cited within this pathfinder under the subsection “Case Law.”
4. The 30 Month Automatic Stay
If a Brander indicates its intent to bring a patent infringement suit, the FDA is prohibited from approving the drug for 30 months or until such time that the patent is found to be invalid. Prior to the 2003 Amendments, abuse of this provision occurred when the Branders amended and added to their listings in the Orange Book. Additional listings required the generic companies to file additional notices, which allowed the Branders to file additional infringement suits, thereby forcing another 30 month stay. The Amendments changed this procedure and now allow only one 30 month stay. Case law includes Mylan Pharm., Inc. v. Thompson and F.T.C v. Mylan Labs., Inc.
5. The Citizens’ Petition – The Citizens’ Petition gives ordinary citizens a voice in the FDA approval process. Oftentimes, however, the Branders themselves file the Citizen Petition to generate market attention. Branders have employed scare tactics and caused citizens to become alarmed or concerned about the safety or efficacy of certain generic drugs, prompting additional letters to the FDA. This has the effect of slowing the generic approval process as the scientific merits must be reviewed by the FDA. The Office of Chief Counsel must review the Citizens’ Petition along with the Office of Generic Drugs’ opinion to render a legal opinion. This process takes time and is a way for Branders to slow and block generic approval. For an example of this tactic, read the recent decision of Glaxo v. Leavitt & Roxane regarding the blockbuster drug Flonase®. Due to the 2003 Amendments’ crack down on the 180 day exclusivity petition and the 30 month automatic stay, the Citizens’ Petition has become the Branders’ tactic of choice. Recently, Scott Gottlieb, Deputy Commissioner for Medical and Scientific Affairs at the FDA gave a speech concerning the recent influx of Citizen’s Petitions. An excerpt from this speech, delivered on April 7, 2006, can be found in the Appendix of this paper.
6. CRS Issue Brief for Congress – www.library.piercelaw.edu: The Pierce College of Law contains one of the most prominent Intellectual Property databases online. The college is the premier cataloger and indexer of legal issues involving intellectual property. Anyone can use the database and you need not be a registered student to conduct a search throughout their extensive collection.

1. Abbot Lab. v. Geneva Pharm., 182 F.3d 1315, (9th Cir. 1999).
Patentee brought action against proposed competitors that filed ANDAs, alleging infringement of patent. The 9th Circuit Court of Appeals held that a third party’s sales of claimed product prior to critical date rendered patent invalid.
2. Andrx Pharm., Inc. v. Biovail Corp. Intern., 256 F.3d 799, (C.A.D.C. 2001).
In an action challenging FDA approval of ANDA, generic drug manufacturer filed counterclaim against competitor alleging antitrust violations. The Court of Appeals for the District of Columbia held that the manufacturer’s complaint should not have been dismissed with prejudice. It remained possible for manufacturer to allege intent and preparedness to enter market, and hence injury-in-fact necessary to establish standing.
3. McGrew v. Schering-Plough Corp., 2001 WL 950790 (D. Kan. Aug. 6, 2001).
Plaintiff alleged violation of Kansas antitrust laws. Defendants removed the case to federal court on June 22, 2001. Plaintiff contends that such removal was improper, because the court lacked subject matter jurisdiction. The court agreed, and denied defendants’ motion for an injunction.
Generic drug manufacturer moved for preliminary injunction ordering brand-name drug manufacturer to de-list its patent from the FDA “Orange-Book” and directing the FDA to approve its ANDA. The District Court held that the generic drug manufacturer was entitled to preliminary injunction since it demonstrated that the public interest favored granting the injunction, and that the balance of harms to the parties did not weigh against granting.
FTC and various states sued manufacturer of generic drugs and suppliers of active ingredients alleging violations of federal and state antitrust laws as a result of allegedly illegal licensing agreements allowing for allegedly excessive pricing of drugs. Defendants moved to dismiss. The District Court held that: (1) FTC could sue for monetary damages, as well as injunction; (2) states could not recover for excess payments for drugs made to competitors of named parties; (3) restitution and disgorgement were available under state statutes only when expressly provided for; (4) monopoly claim was stated; (5) claim of unreasonable restraint on trade was stated; (6) claim of price fixing was stated; and (7) distributor of active ingredients could be included in suit, even though not a signatory to allegedly illegal licensing agreements.
6. Glaxo v. Leavitt & Roxane, 2006 WL 453211 (D.Md. 2006).
Plaintiff Glaxo Group Ltd. (“GSK”) filed a Motion for a Temporary Restraining Order. The Court held that the balance of harms and the public interest clearly weigh in GSK’s favor. The court ordered that during the FDA’s review, the approval and any future approval by the FDA of an ANDA allowing the marketing and sale of a generic version of GSK’s Flonase® Nasal Spray shall be suspended.

I hope that this pathfinder aids individuals interested in the pharmaceutical industry. The industry provides an interesting forum for debate as well as endless amounts of jobs. In today’s society, the independent contractor has a unique opportunity to capitalize on the pharmaceutical industry. One can create a particularized specialty and carve out a niche in this market. The more informed one is on the political rhetoric and the status of the FDA, the easier it will be to take advantage of the opportunities.
I enjoyed my research on this topic because the case law is new, the articles are opinionated, and the laws are changing. President Bush’s agenda includes many changes to the FDA and the generic pharmaceutical industry. Generic drugs increase competition among the pharmaceutical companies and ultimately drive prices down for the consumer. Many big businesses, like Ford and Delta, need this type of price reduction because their payouts for family healthcare plans have become unmanageable.
Branders are some of the leading lobbyists in today’s society. Their wealth allows them to carry a heavy hand in Washington, D.C. As the generic industry grows, they too will have the funds with which to lobby. The legislation pending is uncertain, and this pathfinder serves to provide you with the tools capable of staying at the forefront of these changes. For any additional questions, please feel free to e-mail me at [email protected].
Note: this is an excerpt from the speech and is does not represent the entire speech.
It’s a pleasure to be here with you today and to continue to learn about all of the ways that the generic drug industry’s tremendous progress is helping patients get access to better, more affordable care. At FDA, one of our highest priorities is to enable this progress. As a practicing physician, I am well aware of the enormous contribution to our nation’s health by the more than twelve thousand medications on the market for which American patients will spend an estimated $248 billion last year. I know first-hand some of the improvements in health that have been made possible by the introduction and appropriate use of better medications.
The price of a generic drug can be as low as 20 percent of the price of the brand name product it mimics, according to our analysis of IMS data that is being posted today to our website. Most of these price reductions occur after only two or three generics enter the market. Further, generics are a large and growing part of total medicine use. Newly-completed analysis by FDA shows that about two-thirds of all prescription drugs used in the U.S. in 2004 was generic according to IMS data on U.S. retail sales. Generic drugs represented 66.4 percent of the total prescription doses (extended units) sold in 2004, compared with 61 percent in 2001. Generic drugs are going to continue to grow in importance. According to IMS, brand name medication with annual sales of approximately $64 billion will come off patent in the next 5 years.
The Office of Generic Drugs receives about 40 to 50 first generic submissions a year and has a very strong record of timely approvals for the first generic to reach the market after the parties resolve any patent issues. These first generics have the greatest impact on the market and the public health. They can significantly reduce costs to patients. We promptly review and approve these first generics. Generic companies often receive our approval to market their products on the same day that any patents or exclusivities expire.
Moreover, even after the FDA issued a tentative approval, some potentially important generic drugs have remained unavailable because of legal challenges. In particular, the process of filing citizen’s petitions has come under attack recently by some who assert that sometimes “frivolous” petitions are being used solely to delay the generic approval process.
On that issue, we believe these petitions provide the public an invaluable tool for getting good scientific arguments in front of FDA, and we do not support efforts to close off this important route of dialogue. But we are also looking at ways to make additional improvements in our process for handling these petitions, to make sure that they don’t inappropriately delay entry of legitimate generic drugs because of inefficiencies in our own process.
We are also going to take a strong stand against sponsors who use the litigation process to cast doubts about the generic drug approval process through overly aggressive PR that undermines our finding of safety and effectiveness. Legal battles shouldn’t be allowed to spill out of the courtroom and into the doctor-patient environment and stoke patients’ fears.
The Office is also exploring expediting the review of first generic applications for which there are not patent or other issues that would delay full approval. This approach would focus scarce review efforts on applications that can be approved and made available sooner to the American public. Since the goal is to get generic drug products into the marketplace more quickly, after appropriate patents have expired, it is more effective to focus efforts on reviewing applications that can be approved and marketed while reviewing other applications closer to the time the products could actually be marketed.
