Q2. Which three criteria are universally required for a pharmaceutical invention to be patentable in most jurisdictions?

• Novelty, inventive step (non‑obviousness), and industrial applicability (usefulness)
• Commercial success, long shelf life, and market exclusivity
• Prior disclosure, public domain status, and biological origin
• Formulation stability, dosage accuracy, and manufacturing cost reduction

Correct Answer: Novelty, inventive step (non‑obviousness), and industrial applicability (usefulness)

Q3. In patent law, what is the significance of the “priority date” for a pharmaceutical patent application?

• It is the date used to assess novelty and prior art against which the invention is judged
• It is the date the patent is granted and enforceable worldwide
• It is the expiration date of the patent term after grant
• It refers to the manufacturing start date for the validated batch

Correct Answer: It is the date used to assess novelty and prior art against which the invention is judged

Q4. Which statement best describes a “composition of matter” patent claim in pharmaceuticals?

• A claim covering the chemical entity (active pharmaceutical ingredient), salts, esters, and stable polymorphs
• A claim limited only to synthesis steps of a compound without claiming the product
• A claim that protects marketing materials and brand names
• A claim describing only the therapeutic indication without structural details

Correct Answer: A claim covering the chemical entity (active pharmaceutical ingredient), salts, esters, and stable polymorphs

Q5. What is an SPC (Supplementary Protection Certificate) in the EU context?

• A mechanism that extends the effective protection period of a patented medicinal product to compensate for regulatory approval time
• An additional patent granted automatically after the national patent expires
• A certificate that registers manufacturing sites for GMP compliance
• A compulsory license issued for public health emergencies

Correct Answer: A mechanism that extends the effective protection period of a patented medicinal product to compensate for regulatory approval time

Q6. Which form of IP protection is most appropriate for confidential validation protocols and proprietary process know‑how that should not be publicly disclosed?

• Trade secret protection with confidentiality agreements and limited disclosure
• Filing a utility patent that publicly describes all details
• Registering the protocol as a trademark
• Uploading protocols to open access repositories to claim prior art

Correct Answer: Trade secret protection with confidentiality agreements and limited disclosure

Q7. Which of the following is a correct description of “novelty-destroying prior art” in pharmaceutical patenting?

• Any public disclosure, including publications, patents, or public use, that predates the priority date and discloses the claimed invention
• A confidential internal report that was never shared externally
• A poster presented at a closed meeting attended only by inventors
• Laboratory notebooks kept under an inventor’s control and not published

Correct Answer: Any public disclosure, including publications, patents, or public use, that predates the priority date and discloses the claimed invention

Q8. How does “data exclusivity” differ from patent protection for pharmaceutical products?

• Data exclusivity prevents regulatory authorities from relying on innovator safety/efficacy data for a fixed time, independent of patent status
• Data exclusivity automatically extends patent term by the same duration
• Data exclusivity is identical to trademark protection for drug names
• Data exclusivity allows anyone to use the clinical data immediately after filing

Correct Answer: Data exclusivity prevents regulatory authorities from relying on innovator safety/efficacy data for a fixed time, independent of patent status

Q9. What is the primary legal remedy sought in a patent infringement action relating to a generic drug launch?

• An injunction preventing sale of the infringing generic product and possible monetary damages
• A compulsory license allowing immediate generic commercialization
• Revocation of the innovator’s marketing authorization
• Automatic award of patent ownership to the generic manufacturer

Correct Answer: An injunction preventing sale of the infringing generic product and possible monetary damages

Q10. Which concept describes minor modifications to an existing drug (e.g., new salt form or polymorph) aimed at extending patent life?

• Evergreening
• Public domain dedication
• Patent pooling
• Compulsory licensing

Correct Answer: Evergreening

Q11. In the context of patent claims, what is the difference between an “independent claim” and a “dependent claim”?

• An independent claim stands alone in scope; a dependent claim incorporates and narrows an independent claim
• An independent claim is always narrower than dependent claims
• Dependent claims are filed in different jurisdictions only
• Independent claims protect trademarks while dependent claims protect copyrights

Correct Answer: An independent claim stands alone in scope; a dependent claim incorporates and narrows an independent claim

Q12. What is the purpose of conducting a freedom‑to‑operate (FTO) analysis before pharmaceutical product commercialization?

• To identify third‑party IP that could block commercialization and assess risk or need for licenses
• To validate the analytical methods used during product release
• To obtain GMP certification for the manufacturing site
• To protect trade secrets by publishing all process details

Correct Answer: To identify third‑party IP that could block commercialization and assess risk or need for licenses

Q13. Which international treaty allows a single patent application to be filed to seek protection in multiple countries?

• The Patent Cooperation Treaty (PCT)
• The Berne Convention
• The Madrid Protocol
• The TRIPS Agreement

Correct Answer: The Patent Cooperation Treaty (PCT)

Q14. What is “compulsory licensing” in the pharmaceutical IP context?

• A government authorization allowing a third party to produce a patented product without the owner’s consent under specified conditions
• A voluntary license granted by the patent holder for royalties
• A permanent transfer of patent ownership to the state
• A measure allowing patents to be extended indefinitely

Correct Answer: A government authorization allowing a third party to produce a patented product without the owner’s consent under specified conditions

Q15. Which of the following best describes the “experimental use exception” relevant to pharmaceutical research?

• A limited legal allowance to use patented inventions for non‑commercial research without infringement in some jurisdictions

• Limiting claims only to a single batch number and shelf life
• Focusing claims exclusively on marketing language and brand slogans
• Disclosing all manufacturing trade secrets directly in the claim text

Correct Answer: Claiming the novel composition, key excipient interactions, and unique manufacturing parameters with dependent claims covering critical features

Q17. Which of the following is true about “prior art” searches performed during pharmaceutical patent prosecution?

• They aim to discover publications, patents, and public disclosures that might affect novelty or inventive step
• They are unnecessary if an invention is already in development for several years
• They are limited to in‑house documentation and laboratory notebooks only
• They always guarantee that no future patent opposition will be successful

Correct Answer: They aim to discover publications, patents, and public disclosures that might affect novelty or inventive step

Q18. How does the doctrine of equivalents affect patent infringement analysis for pharmaceuticals?

• It can find infringement even when the accused product does not literally meet claim language but performs substantially the same function in substantially the same way to achieve the same result
• It allows any similar product to be automatically licensed without negotiation
• It limits infringement to exact literal claim language only
• It is only applicable to trademark disputes, not patents

Correct Answer: It can find infringement even when the accused product does not literally meet claim language but performs substantially the same function in substantially the same way to achieve the same result
