The time periods and laws described here are complex and what is presented here is a simplified version of the law.
It is recommended to consult a competent lawyer for advice in this regard, so that they can consider all the details of your situation, including all the dates involved.

In general, this means that if you are considering filing your patent application today or tomorrow, it is best to file it today and not tomorrow. Keep in mind that someone else could independently invent the same topic and publish it tomorrow or use it publicly tomorrow, anywhere in the world.
If you have published your invention or used it publicly at any time in the last year, you should pay close attention to the date on which this event occurred and be sure to consult a competent lawyer as soon as possible and, in any case, before a year has passed since its publication or public use. These are not the only factors that should be taken into account when deciding when to file a patent application (or when to consult a patent lawyer). Many other factors influence the time of filing a U. S.
patent application. On the one hand, there is always the possibility that another person may have filed or will soon file a patent application on the same subject. The sooner you file your request, the more likely it is that it will prevail against another person who has filed it or is about to file an application.

However, it is important to note that if there is a possibility that the inventor may wish to apply for patent protection in countries outside the United States, it is essential to seek advice from a competent lawyer before disclosing or selling the invention to the public. The reason for this is that, in many countries outside the United States, public disclosure of the invention at any time before filing a patent application may prevent its granting. For these reasons, it is advisable to consider the objective of filing the patent application before its public disclosure or sale. In the United States, there are at least two possible approaches to protecting an invention from imminent public use or disclosure: these approaches include filing a non-provisional U.
patent application or filing a United States provisional patent application. File your patent application as soon as possible and, in any case, do so before any public use or publication of your invention. Do not postpone consulting with a competent patent lawyer. How long does a US patent last? A patent granted pursuant to an international application filed before June 8, 1995 and which entered into force with 35 U.
C., § 154(a)(2), will have its term extended until twenty years from its international filing date. If you file a provisional patent application, your priority date remains as the filing date of the provisional application, but you can use the filing date of the non-provisional application to determine its duration. Patents expire when their term ends or they have been abandoned due to non-payment of maintenance fees. Understanding patent deadlines can help protect your intellectual property rights from being exploited, used or sold by someone else.
Patents whose parents had received extensions could apply for similar extensions since their applications were still protected. If the terminal disclaimer of the patent excludes part of its term after full legal validity of a reference patent (without specifying an exact date), then what appears on its front page regarding its duration will be incorrect if full legal validity of said reference patent changes due to 35 U. C., § 154(b)(2). If USPTO does not review an application within established time frames (which vary depending on each step), then its term may be extended.
This 1984 law allows holders of patents to receive an extension due to their patented product not being commercially available while they wait for regulatory approval. In accordance with current US law, patents have a term of 20 years from their first US filing date provided maintenance fees are paid on time. Understanding time frames related to patents including how long they remain valid and when applications should be filed can help protect your intellectual property rights such as inventions or business methods from being exploited, used or sold by someone other than you.
