Final answer:
Inventions may not become world renowned due to various factors such as limited practicality, lack of marketing, and legal restrictions on intellectual property rights.
Step-by-step explanation:
Inventions don't become world renowned objects for everyone to use due to various factors.
Firstly, not all inventions are practical or useful to a wide audience. Some inventions may only cater to a niche market or have limited applicability. For example, a specialized medical device may be groundbreaking but may only benefit a small number of people.
Secondly, the success of an invention depends on factors such as marketing, funding, and competition. Even if an invention is valuable, if it lacks proper promotion or faces stiff competition from similar products, it may not achieve widespread recognition.
Additionally, the legal aspects of intellectual property rights can hinder the availability of certain inventions to the public. Some inventors choose not to patent their inventions, allowing others to replicate or modify them without legal restrictions, limiting their exclusivity and potential impact.
