FAQs Patent Questions

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: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:Patent application publications are available on the Web and at the patent and trademark depository libraries.

Answer:
If an applicant or a practitioner chooses not to print copies of U.S. patents and patent applications publications through the USPTO Patents on the Web system or through the E-Patent Reference system, commercial sources that provide patents very quickly and inexpensively are available, and copies of U.S. patents and patent application publications are also available at the Patent and Trademark Depository Libraries (PTDLs).
