The Famous Pfizer Viagra Patent
Much has been written about the Pfizer Viagra patent. Recently, a District Court held the patent to be valid. All the fighting about this patent is directly related to Pfizer's $1 billion a year in U.S. Viagra sales. The patent itself has been valuated somewhere in the neighborhood of $10 billion.
But have you taken a look at the famous Pfizer Viagra patent? I did, and following are some interesting observations. Click here to see Pfizer's Viagra patent.
First, I am surprised to see how short the detailed description is. At less than six columns, it's one of the shorter patents out there. This goes to show, being brief is a virtue - even when you're dealing with a $10 billion patent. Second, notice how many pages of cited references there are. At 6 pages, that's a lot of references, and no doubt led to a stronger and more valuable patent. Lastly, note there are only two inventors. Though the testing and development of this drug probably cost somewhere in the billions of dollars and involved hundreds or thousands of people, it was only two guys that invented this drug and only two guys that will go down in history.
As inventors and developers of technology, we can only hope to have successful inventions. But it is certain that in order to realize a return on R&D investment, individuals and companies must pursue patents for their inventions. Thus, my recommendation to inventors and technology companies is to seriously consider pursuing patents for their inventions with the U.S. Patent and Trademark Office, especially in cases involving inventions that may generate significant revenue.
