A patent lawyer is a legal professional who specializes 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. In addition to filing patent applications, patent lawyers also provide advice on patentability, conduct patent searches, and represent clients in disputes related to patent infringement. Their expertise is essential for navigating the complex legal landscape surrounding intellectual property rights.
