Step 1: Understanding the Concept:
A patent is a legal right granted by a government to an inventor, protecting their invention from being made, used, or sold by others for a limited period.
Obtaining a patent follows a strict, formal legal and administrative procedure.
Step 2: Detailed Explanation:
Let us arrange the steps of obtaining a patent in their correct chronological order:
-
Step 1: (B) Development of a patentable product:
The inventor must first conceive, design, and develop a novel, non-obvious, and industrially useful product or process.
- (A) Filing an application to the Patent Office:
The inventor submits a formal patent application containing the specification, claims, and technical drawings to the national patent office to secure a filing date.
-
Step 2: (D) Scrutiny and publication of the application by the Patent Office:
The patent office reviews the application for formal compliance, and publishes it in the official patent journal (usually 18 months after the filing date) to make it available for public knowledge.
-
Step 3: (C) Clearing the public challenges or any other issues raised by the Patent Office:
During the opposition period, the public can challenge the patent.
The patent office also conducts a substantive examination, issuing an examination report.
The inventor must address and clear these objections and public challenges before the patent is officially granted.
Therefore, the correct chronological sequence is: (B) $\rightarrow$ (A) $\rightarrow$ (D) $\rightarrow$ (C).
Step 3: Final Answer:
The correct chronological sequence of steps is (B), (A), (D), (C).
