     Some years ago on a hot summer day in south Florida a little boy decided to go for a swim in the old

swimming hole behind his house. In a hurry to dive into the cool water, he ran out of the back door,

leaving behind shoes, socks, and shirt as he went.

     He flew into the water, not realizing that as he swam toward the middle of the lake, a crocodile was

swimming toward him. His mother in the house was looking out of the window and saw the two. In great

fear, she ran toward the water, shouting to her son as loudly as she could. Hearing her voice, the little

boy became alarmed and made a U-turn to swim to his mother. It was too late. Just as he reached her,

the crocodile reached him. From the shore, the mother grabbed her little boy by the arms just as the

crocodile snatched his legs. That began an incredible tug-of-war between the two. The crocodile was

much stronger than the mother, but the mother was much too passionate to let go. A farmer happened

to drive by, heard their screams, raced from his truck, took aim and shot the crocodile.

     Remarkably, after weeks and weeks in the hospital, the little boy survived. His legs were extremely

scarred by the attack of the animal. And, on his arms, were deep scratches where his mother's fingernails

dug into his flesh in her effort to hang on to the son she loved.

     The newspaper reporter, who interviewed the boy, asked if he would show him his scars. The boy

lifted his legs. And then, with obvious pride, he said to the reporter, "But look at my arms. I have great

scars on my arms, too. I have them because my Mom wouldn't let go. "

      Never judge another person's scars, because you don't know how they were made.

When an invention is made, the inventor has three possible courses of action open to him: he can give the invention to the world by publishing it, keep the idea secret, or patent it.

A granted patent is the result of a bargain made between an inventor and the state, by which the inventor gets a limited period of monopoly (垄断) and publishes full details of his invention to the public after that period terminates (终止).

Only in most exceptional circumstances is the life-span of a patent extended to alter this normal process of events.

The longest extension ever granted was to Georges Valensi: his 1939 patent for color TV receiver circuitry was extended until 1971 because for most of the patent’s normal life there was no color TV to receive and thus no hope of reward for the invention.

Because a patent remains permanently public after it has terminated, the shelves of the library attached to the patent office contain details of literally millions of ideas that are free for anyone to use and, if older than half a century, sometimes even re-patent. Indeed, patent experts often advise anyone wishing to avoid the high cost of conducting a search through live patents that the one sure way of avoiding violation of any other inventor’s right is to plagiarize a dead patent. Likewise, because publication of an idea in any other form permanently invalidates (使无效) further patents on that idea, it is traditionally safe to take ideas from other areas of print. Much modern technological advance is based on these presumptions of legal security.

Anyone closely involved in patents and inventions soon learns that most "new" ideas are, in fact, as old as the hills. It is their reduction to commercial practice, either through necessity of dedication, or through the availability of new technology, that makes news and money. The basic patent for the theory magnetic recording dates back to 1886. Many of the original ideas behind television originate from the late 19th and early 20th century. Even the Volkswagen rear engine car was anticipated by a 1904 patent of a cart with the horse at the rear.

The passage is mainly about ().

A. an approach to patents

B. the application for patents

C. the use of patents

D. the access to patents
