n. 1) a trespassing or illegal entering. 2) in the law of patents (protected inventions) and copyrights (protected writings or graphics), the improper use of a patent, writing, graphic or trademark without permission, without notice, and especially without contracting for payment of a royalty. Even though the infringement may be accidental (an inventor thinks he is the first to develop the widget although someone else has a patent), the party infringing is responsible to pay the original patent or copyright owner substantial damages, which can be the normal royalty or as much as the infringers' accumulated gross profits.
