A legal monopoly, granted by the U.S. Patent and Trademark Office (PTO), for the use, manufacture and sale of an invention. Patents on useful devices, called utility patents, last for 20 years from the date the patent application was filed. Design patents last for 14 years from the date issued. And plant patents last for 17 years from the date issued.
patent claim
A statement included in a patent application that describes the structure of an invention in precise and exact terms, using a long established formal style and precise terminology. Patent claims serve as a way for the U.S. Patent and Trademark Office (PTO) to determine whether an invention is patentable, and as a way for a court to determine whether a patent has been infringed. In concept, a patent claim marks the boundaries of the patent in the same way as the legal description in a deed specifies the boundaries of the property.
patent deed
The official document sent to an inventor by the U.S. Patent and Trademark Office (PTO) when that office has issued a patent for the inventor's creation.
patent drawing
Visual representations of an invention that are included in a patent application. Patent drawings must be included in the application unless the nature of the invention precludes such them, as would be the case with the formula for a new substance. Patent drawings should show all the features of the invention described in the application, including those features that distinguish it from prior art.
patent pending
The status of an invention between the time when:a utility patent application has been filed and when it is issued or rejected, or a provisional patent application has been submitted and when a subsequent patent application (filed within one year) is issued or rejected. Inventors often mark their devices "patent pending" to deter competitors from copying the idea or claim it as their own.
patent search
A search for documents that will determine whether a particular invention was novel and nonobvious when it was invented, and hence whether it may qualify for a patent. A patent search usually begins with a database of previously issued patents, and also covers other types of documents, such as journal articles and scientific papers, that describe unpatented inventions.
paternity suit
A lawsuit to determine the identity of the father of a child born outside of marriage, and to provide for the support of the child once the identity of the father has been determined.
pay-on-death (POD) designation
A way to avoid probate for bank accounts, government bonds, individual retirement accounts and, in many states, securities or a car. To create a pay-on-death designation, you simply name someone on the ownership document (such as the registration card for a bank account) to inherit the property at your death. You retain complete control of your property while you are alive, and you can change the beneficiary (payee) at any time. At your death, the property is transferred directly to the beneficiary, free of probate.
pendente lite
Latin for "while the action is pending." This phrase is used to describe matters that are contingent upon the outcome of a lawsuit. For example, money may be deposited by the defendant with the court pendente lite in order to compensate the plaintiff if the defendant loses the case. If the defendant wins, she gets her money back.
pension
A retirement fund for employees paid for or contributed to by some employers as part of a package of compensation for the employees' work. Pensions became widespread during the Second World War, when they were commonly used as lures because there were more jobs than workers.
per capita
Under a will, the most common method of determining what share of property each beneficiary gets when one of the beneficiaries dies before the willmaker, leaving children of his or her own. For example, Fred leaves his house jointly to his son Alan and his daughter Julie. But Alan dies before Fred, leaving two young children. If Fred’s will states that heirs of a deceased beneficiary are to receive the property per capita, Julie and the two grandchildren will each take a third. If, on the other hand, Fred’s will states that heirs of a deceased beneficiary are to receive the property per stirpes, Julie will receive one-half of the property, and Alan’s two children will share his half in equal shares (through Alan by right of representation).
per stirpes
Under a will, a method of determining who inherits property when a joint beneficiary has died before the willmaker, leaving living children of his or her own. For example, Fred leaves his house jointly to his son Alan and his daughter Julie. But Alan dies before Fred, leaving two young children. If Fred’s will states that heirs of a deceased beneficiary are to receive the property "per stirpes," Julie will receive one-half of the property, and Alan’s two children will share his half in equal shares (through Alan by right of representation). If, on the other hand, Fred’s will states that the property is to be divided per capita, Julie and the two grandchildren will each take a third.
peremptory challenge
During jury selection, an opportunity for a party to a lawsuit to dismiss or excuse a potential juror without having to give a valid reason, as would be the case when a juror is challenged for cause. Depending on court rules, each party typically gets to make from five to 15 peremptory challenges. Although parties may generally use their peremptory challenges as they see fit, the U.S. Constitution has been interpreted to prohibit their use to eliminate all jurors of a particular race or gender from a jury.
permanent resident
A non-U.S. citizen who has been given permission to make his or her permanent home in the United States. If you acquire permanent residence, you will be issued a green card to prove it. The terms permanent resident and "green card holder" mean exactly the same thing. You cannot be a permanent resident without a green card and you cannot have a green card without being a permanent resident. As a permanent resident, you may travel as much as you like, but your place of residence must be the United States and you must keep that residence on a permanent basis. If you leave the United States and stay away for more than a year, you risk losing your green card.
personal injury
An injury not to property, but to your body, mind or emotions. For example, if you slip and fall on a banana peel in the grocery store, personal injury covers any actual physical harm (broken leg and bruises) you suffered in the fall as well as the humiliation of falling in public, but not the harm of shattering your watch.
