The law is constantly changing. Moreover, no general discussion can incorporate all the specific facts of your particular situation. Consult an attorney for particular legal questions.


What’s a Patent?


A Patent Is A Limited Monopoly

A patent is a time-nation monopoly the government grants to novel, non-obvious inventions in exchange for the inventor making public, through the application process, a description of how to make the invention. The monopoly--currently 20 years from the effective application date, if maintenance fees are paid for the 4th, 8th, and 12th years--is for the making, using, or selling of the patented invention in the jurisdiction of that government. Filing a proper patent application soon after the invention is reduced to practice is important. To avoid loss of rights and reduce future disputes, consult a intellectual property attorney early if you, or a group you are involved with, may have a patentable invention. In the USA, potential patent rights may be forfeit if the invention is commercialized or publicly described more than one year before the patent application; some foreign jurisdictions require application before any commercialization or public description.

Generally Spherical Object with Floppy Filaments to Promote Sure Capture, Pat 4,756,529

An amusement device which as a substantially  spherical configuration, and which is formed from a large plurality of floppy, elastomeric filaments that radiate in a dense, bushy manner from a central core region. The filaments are sufficiently floppy to collapse on impact, thus to absorb enough energy to avoid any tendency to bounce. They are also sufficiently dense and floppy that they tend to quickly thread their way between the fingers of a user on contact with the hand. These features promote sure and quick capture of the device during the act of actching. Inventor Scott Stillinger, Issued 12 July 1988.
