FAQs Patent Questions
Question:Is it necessary to go to the USPTO to transact business concerning patent matters?
Answer: No. Most business with the Office is conducted by written correspondence. Interviews regarding pending applications can be arranged with examiners if necessary and are often helpful.
Question:Amendment documents that changes an existing claim must include a complete listing of all claims presented
Answer:
Any amendment document that includes a change to an existing claim, cancellation of an existing claim or addition of a new claim, must include a complete listing of all claims ever presented.
Question:If two or more persons make an invention jointly, they apply for a patent as joint inventors
Answer:
If two or more persons make an invention jointly, they apply for a patent as joint inventors. A person who makes only a financial contribution is not a joint inventor and cannot be joined in the application as an inventor.
