are you infringing if you are providing a part that is used in a patented product
Further, you may be considered to infringe a patent if you import items into the United States that are made by a patented method, unless the item is materially changed by subsequent processes or becomes a trivial and nonessential component of another product.he basis of the demand letter appears to be my use of anotherâs product. A patent owner has the right to exclude others from making, selling, offering to sell, importing or using a patented invention. Thus, you may be liable for infringement due to your use of someone elseâs technology.
