Which company won the patent for an innovative flying warehouse designed to deliver parcels to customers using drones?

Introduction / Context:
This question checks your awareness of recent technology related business news and the use of drones for parcel delivery. Major e commerce companies have been experimenting with drones and airborne warehouses to speed up deliveries and reduce ground infrastructure. Knowing which company filed a patent for a flying warehouse helps you relate current affairs with innovation in logistics and supply chain management.

Given Data / Assumptions:
- The question states that one company has won a patent for a flying warehouse designed to deliver parcels by drones.
- The options list well known commerce and payment brands: Flipkart, Amazon, Snapdeal, Paytm and Walmart.
- We assume the question refers to a widely reported international patent for an airborne fulfilment centre that works with delivery drones.

Concept / Approach:
The core concept is simple factual recall from current affairs and technology news. However, even if you do not remember the headline perfectly, you can use logical elimination. Among the options, only one company is globally known for aggressive experimentation with drone based delivery and futuristic warehouse ideas. That reputation serves as a strong clue to the correct answer, even without remembering the exact article or patent number.

Step-by-Step Solution:
Step 1: Recall which company is famous for developing a programme called Prime Air to use drones for fast parcel delivery. Step 2: Remember that news reports described a patent for an airborne fulfilment centre or flying warehouse that would stay in the sky and release drones with packages. Step 3: Connect this futuristic concept with the company that often files ambitious patents in logistics and retail technology. Step 4: Identify that company as Amazon, while the other options are either Indian commerce companies or do not match this specific patent story. Step 5: Conclude that Amazon is the only option that fits both the patent and the global drone delivery project.

Verification / Alternative check:
A quick mental verification is to ask which brand you associate most strongly with images of small quadcopter drones flying parcels to customers. That brand is Amazon through its Prime Air promotion videos and many news articles. None of the other listed companies have been consistently in global news for similar projects. This cross check confirms that Amazon must be the company that secured the patent for a flying warehouse to work with drones.

Why Other Options Are Wrong:
Flipkart is a major Indian e commerce company but it has not been widely reported as owning this specific flying warehouse patent.
Snapdeal is another Indian marketplace that has not been linked to such a large scale drone patent story.
Paytm is primarily known for digital payments and financial services, not for warehouse or drone patents.
Walmart has logistics strength and has tested drones, but the famous airborne warehouse patent in this context belongs to Amazon and not Walmart.

Common Pitfalls:
A common mistake is to guess an Indian e commerce company such as Flipkart simply because the exam is for Indian students. Another error is to think of Walmart as a strong rival and assume that it must also have filed the most futuristic logistics patents. Some learners also misread the question and focus on drones rather than the key phrase flying warehouse, which points more clearly to Amazon. Carefully reading the entire stem and linking it to widely reported innovations avoids these traps.

Final Answer:
The company that won the patent for a flying warehouse designed to deliver parcels via drones is Amazon.
