Viagra generic entryThe story of Viagra’s patents and generic entry of sildenafil citrate is a valuable one because it covers many of the nuances of drug patenting and generic entry in the United States.
This article will describe the multiple patents, patent term extension, pediatric extension, litigation, out-of-court-settlement, and authorized generic fighter brand elements which led to Viagra’s long patent life and limited early entry of generics, and Pfizer’s post generic-entry strategy to limit the impact of competitors.
was approved in 1998, and the original patent covering Viagra was, which received a 283-day patent term extension giving it an expiration date of March 29th, 2012. This 14-year patent life is longer than many other drugs, but Pfizer was able extend the patent-protected life even further.
The ‘534 patent was filed in 1990, and in 1994 (four years prior to Viagra’s launch) Pfizer filed a second patent:. Because the ‘012 patent was filed prior to June 8th 1995 its term is17 years from the grant date, rather than20 years from the filing date, which is how expiration is determined for patents filed after Jun 8th 1995. The ‘012 patent was granted on October 22nd, 2002, so the original expiration date was set to October 22nd, 2019 — more than twenty years after the drug’s launch. The patent’s expiration was extended to April 22nd 2020 because Pfizer responded to an FDA request to perform pediatric clinical trials, granting six months of “” protection.
Pfizer successfully defended Viagra’s patents in many over the years, but one lawsuit stands out. Despite prevailing in awhich affirmed the validity of patent 6,469,012, in 2013 Pfizer announced an, granting Teva a license to manufacture and sell genericstarting in December 2017, more than two years before Viagra’s patent expiration. Importantly, this was not a ‘‘ patent settlement, as Teva was required to pay Pfizer a licensing fee to produce the generic.
Generic drugs sell at a discount to the branded version, which hurts branded revenues, but there are things which brands can do to limit the impact. A popular tactic it to launch an. In this strategy the branded firm licenses a third party to market the branded drug under another name, compelling the generic entrant (in this case Teva) to compete in the generic market. The authorized generic for Viagra was and it was.
Viagra’s 2016 US sales were approximately 1.2 billion, and in 2017 they dropped to less than $800 million. With increased competition from Teva and from Revatio, revenues are expected to keep dropping, and widespread generic competition from the many companies with will further-decrease Viagra sales. It appears that Pfizer is responding to increased competition by increasing Viagra’s price — the has been a general increase over time.
The story of Viagra and the generic entry of sildenafil citrate illustrates the value of data and the need to continuously re-evaluate factors affecting generic entry. Reliance on the first patent would have vastly under-estimated the date of generic entry, and looking solely at the expiration date of the second patent would have missed the December 2017 generic entry.

Viagra patents – 10Viagra tentative.The FDA approved Viagra for use in the treatment of erectile dysfunction in men, which has been associated with a higher risk of sexual activity. However, the drug has not been proven to be safe and effective.
A total of 10 years of experience in the field of erectile dysfunction.
“I am an experienced sexologist and I have been with many patients for their sexual problems. I have been on Viagra for over a year now,” said Dr. Andrew Goldstein, Director of Sexual Medicine at the Mayo Clinic. “Viagra has been a game-changer for me. It’s been an exciting and exciting journey. My patients often come to me with questions, so I always ask them about their sexual problems and I always give them answers. It was a wonderful experience for me.”
About 6,000 patients have been diagnosed with erectile dysfunction, which is the inability to achieve or maintain a firm erection sufficient for sexual intercourse. The disease also causes a decrease in blood flow to the penis to facilitate an erection.
Viagra is a well-known drug used to treat erectile dysfunction and is one of the most popular medications for this condition.
“I had been on Viagra for over a year. I was on this for almost a year and it seemed to be working pretty well. It took me about 2 days to get to the point where I could have a hard erection,” said Dr. Goldstein, who has extensive experience in the field of erectile dysfunction. “My wife was very upset and I was so upset. I went to the local sexual health clinic and we asked if I could see a doctor. She said, ‘No, no, no. It’s not necessary.’ She told me that she was having a heart attack and I had a hard time keeping my erection hard enough for sex. I took Viagra because it made me last longer.”
Viagra has been a game-changer for men suffering from erectile dysfunction who had previously suffered from other health problems.
“In my experience, it has been an exciting and exciting journey,” said Dr. Goldstein. “I started taking Viagra because of my heart condition, so I was able to keep my erection hard enough for sex. I was also able to keep my erection strong enough for sex. Now I am taking it because of my new heart condition and my wife is upset and I cannot keep it hard enough for sex. I have been on it for a year and I am still very happy with the results.”
“I am very grateful to Dr. Goldstein for his experience,” said Dr.
“He has been a great partner for me and has been a great help in my treatment journey. He is very knowledgeable about the drug and has a very positive opinion about the patient.”
“I have had many patients experience the benefits of taking Viagra and I am very excited to have them on the market with me,” said Dr. “I am happy to be on Viagra and I hope that it will help me get back to enjoying life again.”
