The aroma of freshly baked bread filled Leo’s kitchen. He twirled a strand of spaghetti around his fork, savoring the flavor of the tomato sauce he’d been perfecting for years. His pasta-making machine was going to change the world. No more long queues at the pasta store. Fresh, homemade pasta in minutes.

He wiped his hands on his apron and reached for his laptop. The patent application should be finalized soon. He’d spent countless hours perfecting the design, tweaking the internal mechanisms, and ensuring it produced the perfect pasta shape. This was the moment of truth.

The screen displayed the rejection notice. "Prior art exists." Someone else, a large appliance manufacturer, had already developed a similar product. Leo’s fork clattered to the floor, the delicious meal suddenly tasting like ashes. He felt a deep sense of disappointment.
