Although, the length of utility and plant patent protection (patent term) was previously seventeen years from the date of patent grant, utility and plant patents filed after June 8, 1995 now have a patent term of up to twenty years from the date of filing of the earliest related patent application. Utility and plant patents which were applied for prior to June 8, 1995, and which were or will be in force after June 8, 1995, now have a patent term of seventeen years from the date of patent grant or twenty years from the date of filing of the earliest related patent application, whichever is longer. Utility patents are subject to the payment of periodic maintenance fees to keep the patent in force. Patent terms can be extended under some specific circumstances. See the U.S. Code Title 35 - Patents for a full description of patent laws. When approached with this legal assertion, as a patent counselor for your client, you need insights to help you define and determine your defense. No, I am not: A patent is defined by its language, and many times, proper preparation for a Markman Hearing, or Claim Construction Hearing, can determine the summary judgment. If you are accused of infringing on a claim, you want to find ways to minimize the scope of the claim [on the other hand, if you are accusing, you want to broaden a claim's scope]. With IP Street, you can scrutinize a claim in various ways. Your patent is invalid: Since the USPTO granted the patent, the presumption is that all of its claims are valid. Anyone can challenge the validity of a patent (request re-examination) whether or not an infringement injunction has been made. [Normally, when the USPTO learns of an infringement lawsuit, out of due diligence, they open a re-examination case.] The quickest path to invalidate a patent is to identify prior art. A utility patent application can be filed provisionally or unprovisionally. The non-provisional application establishes the filing date of your patent application and begins the examination process. Your patent application will be examined by the USPTO. A provisional application only establishes your filing date and expires automatically after one year. You may file a provisional application when you are not ready to enter your application into the regular examination process. A provisional application establishes a filing date at a lower cost for a first patent application filing in the United States. A provisional application allows the term "Patent Pending" to be applied to your invention. |
