Finding Intellectual Property Publications


patent is an intellectual property right granted by the Government of the United States of America to an inventor "to exclude others from making, using, offering for sale, or selling the invention throughout the United States or importing the invention into the United States" for a limited time in exchange for public disclosure of the invention when the patent is granted.

patent does not grant the inventor the right to make, use, offer for sell, etc. only the right to exclude others from doing so.  U.S. patents are effective only within the United States. The federal government does not enforce a patent that is responsible of the patentee.

There are three types of U.S. patents:  Utility, Design, and Plant. Utility Patents cover new and useful processes, machines, articles of manufacture, composition of matter, or any new and useful improvement to any of the above.  Design patents cover new, original, and ornamental design for an article of manufacture, and finally Plant Patents cover distinct and new varieties of a plant.  In the United States patents are granted by the federal government and governed by federal law.  Since 1985, Utility and Plant Patents are granted for a term which begins with the date of the grant and usually ends 20 years from the date of application subject to the payment of appropriate maintenance fees, while Design Patents last 14 years from the date granted. 

Since June 8, 1995 inventors have had the option of filing a "provisional application for a patent".  Because it is not examined, etc. like a traditional (nonprovisional) patent application, an earlier filing date can be established.  A provisional application is only good for 12 months, cannot be renewed, and a traditional application should be filed within 12 months to lock in the early filing date.  This low cost first filing method allows the term "Patent Pending" to be applied in connection to a description of the invention.

Besides the United States, other nations also grant patents, and while the types are similar, there are some very marked differences in the protection granted, the processes, etc.  One of the most notable is in what constitutes "new".
