The USPTO applauds the efforts of those in the private sector who are bringing their expertise to bear on behalf of America’s entrepreneurs, by empowering inventors with the information, tools, and resources needed to better navigate the ever-evolving IP terrain. Their contributions serve as a keen reminder that, by working together, we can build an ever stronger intellectual property system. This page contains links to external websites that offer certain services free of charge and/or with site registration that may assist persons faced with demand letters or infringement suits. The USPTO is providing these links for information purposes, in order to assist the public in locating free resources that may be helpful to them.

  • Related Suits
    Information about whether a patent has been the subject of a lawsuit can be helpful to someone who has received a complaint or a demand letter, including helping them identify other parties who might have faced similar issues and providing information about the outcomes of other lawsuits involving the patent.

  • More about the Patents, (e.g., Owners, Related Patent, Administrative and District Court Litigation History and Counsel)
    In order to determine how best to proceed after receiving a demand letter or after having been sued for infringing a patent, it is useful to determine as much information as possible about the patent. For example, information about other people and companies who have dealt with the patent and patent owner may be useful to identify how other parties and/or attorneys who might have faced similar issues resolved them. Information about market activity of patents can help provide information about how patents raised in materials you have received are used in commerce. Information about legal proceedings involving patents, including proceedings before the USPTO, can be useful in determining how to respond to a demand or infringement suit.
