To determine whether or not you are infringing a patent, you or your attorney would need to compare a patent’s claims and the accused product, system, or process. To infringe a patent, the accused must perform each and every element of one or more of its claims, or actively encourage, sell or offer to sell a component that leads to another’s infringement. The best way to understand each claim is in light of the description provided through the patent (called the “specification”). A person knowledgeable in the technology should be able to read the specification and be able to tell how to make and use the invention.
