FAQs Patent Questions

Question:If two or more persons work together to make an invention, to whom will the patent be granted?

Answer:
If each had a share in the ideas forming the invention as defined in the claims – even if only as to one claim, they are joint inventors and a patent will be issued to them jointly on the basis of a proper patent application. If, on the other hand, one of these persons has provided all of the ideas of the invention, and the other has only followed instructions in making it, the person who contributed the ideas is the sole inventor and the patent application and patent shall be in his/her name alone.

Question:How long is a patent granted for?

Answer:
Patents expire 20 years from the date of filing. Many other factors can affect the duration of a patent.

Question:Is there any danger that the USPTO will give others information contained in my application while it is pending?

Answer:
Most patent applications filed on or after November 29, 2000, will be published 18 months after the filing date of the application, or any earlier filing date relied upon under Title 35, United States Code. Otherwise, all patent applications are maintained in the strictest confidence until the patent is issued or the application is published. After the application has been published, however, a member of the public may request a copy of the application file.
