To qualify for any form of patent in the US, an inventor must file a patent application with the PTO – an agency within the Department of Commerce – which is expected to be in three parts.

The first is the ‘specification part’, which generally describes the invention. The second is the ‘claims part’, which provides a more detailed statements explaining clearly how the invention works or is assembled. The third is the ‘drawings part’ that gives an illustrative framework of the invention.

Any inventor seeking to get a patent for his invention would need to hire a patent lawyer or a specially qualified professional called a patent agent to help guide him or her with the preparation of the application.
An official at the PTO, known as a patent examiner, would then review the application to determine if it qualifies for a patent.

This goes without saying that the applicant cannot receive any patent rights until the PTO approves and issues the patent.

It is expected that the patent examiner could ask the applicant to answer various questions about his or her invention, during the patent examination process.

By law, an applicant for patent is required to disclose all relevant information in his or her possession before the patent could be issued.
An important factor that the PTO would have to consider before granting an approval for any patent is the usefulness of an invention.

What this means is that no patent will be granted for any invention that is deemed only useful for illegal or immoral purpose.

What causes ED in men?
Erectile dysfunction is a condition that affects men. It is characterized by an inability of the male to successfully have an erection. For a long time researchers and medical experts were unclear as to what was responsible for male impotency. Many were convinced that the condition of erectile dysfunction was one caused primarily by psychological factors.

Simply put, the man’s impotency was simply locked up in his head. Although recent events have revealed that this indeed is one of the factors responsible for impotency, it only accounts for less than 30% of the recorded cases.

Instead, most of the men who are diagnosed with erectile dysfunction are found to suffer from physically induced symptoms. There are many reasons why this might occur but men who suffer physically induced impotency find that their body is unable to deliver adequate blood flow to the male organ.

The effect of an erection in a man is triggered by the absorption of blood by tissues located within the penis.. As this tissue absorbs the inflow of blood, it becomes bigger and gains in mass.

It remains this way until ejaculation, at which point the vein responsible for the outflow of blood releases its constricted stance and allows the held blood to flow out of the penile area.

However, for men who are suffering from physical impotence, the inflow of blood which is required for the inflation of this penile tissue does not occur. This might be as a result of insufficient pressure from the heart or weak arteries which are unable to support the required flow of blood.

The treatment of this kind of impotency is achieved with Viagra pills. Viagra tablets are also referred to as PDE-5 inhibitors. As a result of their actions many of the blood vessels in the body—in this case the penile arteries are able to relax and allow an increase flow of blood into the penis.

The arteries remain in this state for as long as the effects of Viagra are found to last. This is normally found to be at least 4 hours.

There are many conditions that have been shown to be responsible for this form of impotency. For instance, cardiac conditions, Multiple sclerosis and diabetes can result in a weakened flow of blood in the system, Popular lifestyle habits such as drinking and smoking also contribute towards the degeneration of the arteries.

For all these conditions and more, the symptom of erectile dysfunction can be treated by using anti impotence pills like Viagra.

Viagra tablets are produced by the pharmaceutical company Pfizer. Since its release 10 years ago, more than a billion Viagra tablets have been sold. One of the reasons behind its huge popularity can be traced to the efficiency of the tablet.

Sold in dosages of 25mg, 50mg and a 100mg Viagra tablets have proven to be successful in more than 80% of the cases treated.

Taking of Viagra pills, just like every other drug, can sometimes result in negative side effects. These is as a result of the increased flow of blood in the body.
