The sunlight streamed through the window, illuminating the dust motes dancing in the air as Marco polished his self-cleaning window prototype. He whistled a jaunty tune, anticipating the upcoming presentation to investors. He felt a light, almost bubbly feeling as he envisioned the future. His invention would change the world! No more tedious window washing.

The phone rang. It was his lawyer. The tone was somber. “I have some bad news, Marco. Someone else patented something remarkably similar… a year ago.”

He dropped the rag, the jaunty tune dying in his throat. He ran a hand through his hair, the buoyant sensation fading. The investors, the future… it all seemed to shrink away. He knew it was over. He was devastated.
