Patent lawyers are legal professionals who specialize in helping inventors and businesses protect their inventions and intellectual property. They assist clients in obtaining patents, which are legal rights granted by the government that allow inventors to exclude others from making, using, or selling their inventions for a certain period of time. These lawyers also provide guidance on patentability, conduct patent searches, and represent clients in disputes related to patent infringement. Their expertise is crucial in navigating the complex legal landscape surrounding intellectual property and ensuring that inventors can safeguard their innovations effectively.
