✍️ Sample Patent Bar Exam Questions & Answers
1. What does 'first to file' mean in patent law?
The 'first to file' system, adopted in the U.S. with the America Invents Act (AIA), means that the first inventor to file a patent application for an invention is generally entitled to the patent, regardless of who was the first to invent. This system simplifies the process by making the filing date paramount, providing greater certainty and reducing disputes over inventorship dates. It encourages prompt filing of patent applications.
2. What is the 'on-sale bar' under 35 U.S.C. § 102(a)(1) of the AIA?
The on-sale bar renders a patent invalid if the claimed invention was on sale in the United States before the effective filing date (with a one-year grace period for the inventor's own sales under the AIA).
3. Which doctrine requires a patent applicant to be bound by arguments and claim amendments made during prosecution to distinguish prior art, even after the patent issues?
Prosecution history estoppel prevents a patentee from recapturing claim scope surrendered during prosecution through narrowing amendments or arguments distinguishing prior art.
4. What does 35 U.S.C. § 101 refer to?
35 U.S.C. § 101 is a foundational section of U.S. patent law that defines what types of inventions are eligible for patent protection. It states that "Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter... may obtain a patent therefor." This section establishes the broad categories of patentable subject matter, setting the initial hurdle for patent eligibility.
5. What is the best practice for maintaining design patents performance over time?
Scheduled preventive maintenance catches potential issues before they cause failures, maintaining reliability and extending equipment life.
6. Which of the following is true regarding the filing of a continuation application claiming priority to a design patent application?
A continuation design application must be filed before the patenting, abandonment, or termination of proceedings in the parent design application.
